ADAM SAVAGE...

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

NOPE. [ SIGHS ]

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

I'M GONNA TELL YOU THE STORY ANYWAY.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

IT COMES FROM THE FANSITE AND OBVIOUSLY IT'S FROM WORLD WAR I.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

ARE YOU GONNA MAKE SOME KIND OF JOKE

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

ABOUT ME BEING A BOY IN WORLD WAR I?

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

NO. I PROMISE I WON'T.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THE MYTH IS THAT IN WORLD WAR I,

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

GERMANS WERE VERY PRECISE

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

ABOUT THE DIGGING OF THEIR TRENCHES.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

TOWARDS WHAT END?

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THEY THOUGHT WHEN A MORTAR LANDED IN THE TRENCH,

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THE 90-DEGREE CORNERS

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

WOULD PREVENT THE BLAST PRESSURE WAVE

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

FROM TRAVELING TOO FAR IN THE TRENCH.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THEY REALLY WERE SPECIFIC ABOUT IT BEING SHARP CORNERS.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THEY DIDN'T WANT ROUNDED CORNERS

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THAT WERE WORN AWAY BY PEOPLE WALKING THROUGH.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

SHARP, SHARP CORNERS.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

THAT'S THE STORY.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

ALL RIGHT.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

EARTH-MOVING EQUIPMENT AND EXPLOSIVES!

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

SOUNDS LIKE A PERFECT DAY.

AREN'T YOU GONNA ASK ME ABOUT MY COSTUME?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

BUT COULD A CAREFULLY CONSTRUCTED CORNER

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

REALLY HAVE AN IMPACT ON SOLDIERS' SURVIVAL?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

IT'S A MYTH THAT SHAKES DOWN TO SHOCKWAVES.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

A CLUMSY CORNER WILL SUPPOSEDLY LET A SHOCKWAVE SAIL RIGHT PAST,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WHILE A PERFECT PITCH WILL STOP IT DEAD.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

BUT WILL THIS MYTH HIT THE WALL?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WHAT'S THE PLAN?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WELL, I'M THINKING ABSOLUTELY THIS IS A STORY

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT WE WANT TO START IN SMALL SCALE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

I'M THINKING SPECIFICALLY USING WATER RIPPLES AS OUR WAVES

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND WATCHING THEM MOVE THROUGH ENVIRONMENTS

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT MATCH THE SHAPE OF THE TRENCHES

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT WE'RE THINKING ABOUT.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT MAKES SENSE, AND I TELL YOU WHAT --

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WHY DON'T WE MAKE IT LIKE ONE OF THOSE WAVE MACHINES, YOU KNOW?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THE DESKTOP TOY THAT HAS OIL OVER TINTED WATER?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

FANTASTIC.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT WILL SLOW DOWN THE REACTION

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND HOPEFULLY WE CAN SEE WHAT'S GOING ON.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

EXACTLY.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

SO, SUPERSONIC SHOCKWAVES WE'LL LET RIP LATER.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AS THE GUYS FIRST DIVE INTO THIS MYTH WITH WATER.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Adam: THIS WHOLE STORY IS ABOUT HOW DIFFERENT-SHAPED TRENCHES

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AFFECT THE PROPAGATION OF BLAST PRESSURES

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THROUGH THOSE TRENCHES,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND WE WANT TO INVESTIGATE SOME OF THESE SHAPES HERE IN THE SHOP

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

BEFORE GOING FULL SCALE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WE'VE DECIDED TO BUILD OUR TRENCHES OUT OF CLEAR ACRYLIC,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND WE'RE GOING TO FILL THEM FULL OF OIL AND WATER

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

TO WATCH THE WAVE PROPAGATION.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

ISN'T THAT COOL?!

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WE'RE GONNA BUILD ONE LONG STRAIGHT ONE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

IT'S NOT PRETTY, BUT IT'LL DO.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WE'RE GONNA BUILD ONE THAT'S, KIND OF, LIKE A STEP.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

FREAKING SEXY, MAN.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND THEN WE'RE GONNA BUILD ONE LOOSEY GOOSEY ONE

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

TO SEE WHAT EFFECT THE ROUND EDGES HAVE

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT'S DIFFERENT THAN THE SHARP EDGES.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT'S HOW YOU ARE MEANT TO BE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

YES.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

IT'S ALL FALLING INTO PLACE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Narrator: WITH THE THREE TINY TRENCHES BONDED TOGETHER,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THE FILLING CAN COMMENCE -- FIRST WITH WATER,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND THEN WITH BABY OIL.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THIS IS ALL THE BABY OIL SAN FRANCISCO HAD TODAY.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

SOMEWHERE IN THE WORLD, THERE'S A LOT OF ROUGH BABIES.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

NARRATOR: THE TRICKY TRIO OF OIL, WATER, AND FOOD DYE...

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Adam: THAT LOOKS COOL, DOESN'T IT?

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Narrator: ...SHOULD ENSURE

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT ANY WAVE PROPAGATION PATTERN IS CRYSTAL CLEAR.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

[ LAUGHS ]

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

I LIKE IT WHEN MY WAVES SMELL LIKE BABIES!

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Narrator: BUT WHAT'S ALSO CLEAR

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

IS AN EXPLOSION IN AIR IT AIN'T.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Adam: NOW BEFORE YOU GET ALL UP IN ARMS

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

ABOUT THE FACT THAT THIS MYTH IS ABOUT BLAST-PRESSURE WAVES

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND WE'RE DOING A BUNCH OF SCALE EXPERIMENTS

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WITH PLEX BOXES AND OIL AND WATER,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

PLEASE REMEMBER THAT AN OCEAN WAVE...

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WHOA!

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

...A SOUND WAVE... [ GLASS BREAKS ]

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

...AND A BLAST-PRESSURE WAVE

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

ARE ALL EFFECTIVELY, MECHANICALLY THE SAME THING.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THEY ARE A MOVING WAVE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND SINCE THIS WHOLE STORY IS ABOUT THE IDEA

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

THAT THE SHAPE OF A TRENCH CAN AFFECT A WAVE,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

WE CONSIDER THESE SCALE TESTS TO BE TOTALLY VALID

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

AND ANALOGOUS TO WHAT WE EXPECT TO SEE WHEN WE GO FULL SCALE.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Narrator: THE FINAL INGREDIENT FOR THIS ACCURATE ANALOGY

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

IS TO CREATE A CONSISTENT CREST.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

NOW I'VE GOT TO FIGURE OUT A WAY TO DO THIS MECHANICALLY,

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

BUT I THINK I'VE GOT AN IDEA.

WORLD WAR I's TRENCH WARFARE WAS RETCHED,

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AND THIS TIME GETS HAMMERED.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AND BEFORE YOU CAN SAY "SURF'S UP,"

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

HE'S GOT WAVES AS SMOOTH AS SILK,

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

MEANING THE EXPERIMENT CAN BEGIN.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

Adam: SO, THIS IS OUR IMPULSE WAVE.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

IT IS OUR STAND IN FOR A SHOCKWAVE.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

THE MOTOR IS GIVING AN EXACTLY PERFECT PULSE

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AND DELIVERING A WAVE THAT CARRIES

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

ALL THE WAY TO THE END OF OUR TANK

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

WITH A MEASURABLE AMPLITUDE -- THAT IS, A HEIGHT.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

NOW WHAT WE'RE GONNA DO IS PUT THIS RIG

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AT THE SAME EXACT ORIENTATION IN EACH OF OUR TANK TRENCHES

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AND SEE WHAT EFFECT THEIR SHAPE HAS

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

ON THE AMPLITUDE OF THE WAVE AT THE END.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

Jamie: SO ARE WE READY TO MARK IT DOWN?

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

YEAH. LET'S GET OUR CONTROL DONE.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

LIGHTS!

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

ISN'T THAT COOL?

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

HERE WE GO.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

Narrator: ON CUE, THE MACHINE RIPPLES INTO ACTION

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

BEFORE ADAM MARKS THE WAVES' HIGH AND LOW POINTS

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

AT THE FAR END OF THE STRAIGHT TRENCH.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

Adam: OUR CONTROL WAS SUCCESSFUL.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

OUR WAVE-IMPULSE MACHINE GAVE US A WAVE HEIGHT

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

FROM TOP TO BOTTOM AT THE END OF THE TANK

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

OF THREE QUARTERS OF AN INCH.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

NOW WE WANT TO FIND OUT IF WE GET THE SAME RESULTS

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

WHEN WE RUN THIS SAME TEST THROUGH A RIGHT-ANGLE BEND.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

OIL AND WATER WAVE TEST IN A RIGHT-ANGLE TANK.

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

THREE, TWO, ONE...

Narrator: SO ADAM HITS THE WORKSHOP ONCE MORE,

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

JUST RIGHT OFF THE TOP OF MY HEAD.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

IT'S A LOT LARGER ON THIS END THAN IT IS ON THIS ONE.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

YEAH. THAT IS COOL.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

Jamie: OUR RIGHT-ANGLE TANK SEEMS TO BE QUITE EFFECTIVE

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

AT REDUCING WAVE AMPLITUDE.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

AFTER THE FIRST CORNER, IT WAS REDUCED BY TWO-THIRDS,

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

AND AFTER THE SECOND CORNER, IT WAS REDUCED BY THREE-QUARTERS.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

THAT'S SIGNIFICANT.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

Narrator: YEP, BY THE TIME THE WAVE REACHES THE END OF THIS TANK,

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

ITS SIZE HAS BEEN SEVERELY SLASHED,

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

MEANING THAT THE SHARP CORNERS

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

DID SHIELD THEIR SHOCKWAVE STAND IN.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

SOFT CORNERS, HERE WE COME.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

Narrator: SO, HOW WILL THEIR CURVED CORNER COMPARE?

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

GO.

HUH...LOOKS LIKE A PRETTY CLEAR RESULT

IT LOOKS A LITTLE BIGGER DOWN HERE.

IT DOES LOOK A LITTE BIGGER DOWN THERE.

IT LOOKS A LITTLE BIGGER DOWN HERE.

WE MIGHT HAVE SOMETHING.

IT LOOKS A LITTLE BIGGER DOWN HERE.

AND ON CLOSER INSPECTION, THEY DO.

IT LOOKS A LITTLE BIGGER DOWN HERE.

THIS TEST'S WAVE HEIGHT IS A QUARTER OF AN INCH --

IT LOOKS A LITTLE BIGGER DOWN HERE.

LOWER THAN THE CONTROL, BUT HIGHER THAN THE SHARP-TURN TANK.

IT LOOKS A LITTLE BIGGER DOWN HERE.

SO, WHAT DOES THAT MEAN FOR THE MYTH?

IT LOOKS A LITTLE BIGGER DOWN HERE.

SO THE MYTH IS THAT IN WORLD WAR I,

IT LOOKS A LITTLE BIGGER DOWN HERE.

GERMANS BUILT THEIR TRENCHES ON PRECISE 90-DEGREE ANGLES

IT LOOKS A LITTLE BIGGER DOWN HERE.

ON THE ASSUMPTION THAT IT WOULD LIMIT THE STRENGTH OF SHOCKWAVES

IT LOOKS A LITTLE BIGGER DOWN HERE.

TRAVELING THOROUGH THE TRENCHES.

IT LOOKS A LITTLE BIGGER DOWN HERE.

OUR SCALE TESTING HERE IN THE SHOP

WITH OUR SMALL-SCALE TRENCHES

OUR SCALE TESTING HERE IN THE SHOP

IN ALL THE SHAPES THAT WE'VE TRIED

OUR SCALE TESTING HERE IN THE SHOP

SEEMS TO SUGGEST THAT THEY MIGHT HAVE BEEN RIGHT.

OUR SCALE TESTING HERE IN THE SHOP

THIS IS ONE OF MY FAVORITE SCALE EXPERIMENTS

OUR SCALE TESTING HERE IN THE SHOP

WE'VE EVER DONE.

OUR SCALE TESTING HERE IN THE SHOP

WHAT DO YOU THINK?

OUR SCALE TESTING HERE IN THE SHOP

WELL, THIS STORY IS ABOUT BLAST PRESSURE.

OUR SCALE TESTING HERE IN THE SHOP

WE NEED EXPLOSIVES. ABSOLUTELY.

OUR SCALE TESTING HERE IN THE SHOP

THAT IS DEFINITELY THE NEXT STEP --

OUR SCALE TESTING HERE IN THE SHOP

DIGGING SOME TRENCHES AND BLOWING SOME STUFF UP.

OUR SCALE TESTING HERE IN THE SHOP

YEP. I'M GONNA GET A COSTUME ON.

OUR SCALE TESTING HERE IN THE SHOP

OKAY. [ LAUGHS ]

OUR SCALE TESTING HERE IN THE SHOP

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ OLD-TIME HORN HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

ALL RIGHT, I'VE GOT A CRAZY MYTH FOR YOU.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

IT INVOLVES CLOWNS AND CAR CRASHES.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

TWO CLOWNS ARE DRIVING TO A PARTY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THE CLOWN IN THE PASSENGER SIDE HAS A BIG BUNCH OF BALLOONS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHAT HAPPENS?

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THEY GO OUT OF CONTROL AND CRASH THE CAR?

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

EXACTLY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, THE DRIVER CLOWN IS WEARING A SEATBELT,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

SO WHEN THEY CAREEN INTO A WALL, HE'S FINE,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT THE PASSENGER IS NOT.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHAT, AND THE BALLOONS SAVE HIM?

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

EXACTLY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: IT'S A MYTH THAT MAKES FOR ONE HECK OF A HEADLINE.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ HORN HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT CAN A BUNCH OF PARTY BALLOONS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

REALLY ACT AS AN IMPROVISED AIRBAG,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

OR WILL THIS ROAD-SPEED WIPEOUT GO POP?

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

ALL RIGHT, THIS IS WHAT WE SHOULD DO.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE SHOULD CRASH TWO CARS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE'LL HAVE THEM TRAVELING AT ROAD SPEEDS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

OF AROUND 35 MILES AN HOUR,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND WITH THE FIRST CAR, WE'LL SEE WHAT HAPPENS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

TO AN UN-SEAT BELTED PASSENGER.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

GREAT, AND FOR THE SECOND ONE,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE CAN PUT AN AVERAGE BUNCH OF BALLOONS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

IN THE PASSENGER SEAT

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND SEE WHAT THAT DOES TO THE G-LOADS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

OKAY. LET'S START CLOWNING AROUND.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Tory: SO, WE ARE TESTING THE MYTH THAT A BUNCH OF BALLOONS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WILL SAVE A CLOWN'S LIFE IN A CAR CRASH.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, WE ARE GONNA BE CRASHING A BUNCH OF VEHICLES,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT BEFORE WE STICK A CLOWN AND BALLOONS IN THERE,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE NEED TO TRANSFORM THAT INTO A CLOWN CAR.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

LET'S GO TO WORK.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: ACCORDING TO POLICE REPORTS,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THE CLOWNS WERE DRIVING A RUN-OF-THE-MILL RUNAROUND

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

LIKE THIS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

I JUST FEEL SILLY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

I DON'T KNOW WHY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: ALBEIT ONE THAT HAD BEEN PIMPED FOR A PARTY.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Tory: YEAH. IT'S A BLUE CIRCLE.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: AND AFTER TORY FINISHES HIS STRIPES AND STARS,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THIS CAR IS READY TO TAKE THE PLUNGE.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Tory: SO, THE CLOWN CAR IS DONE.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW IT'S TIME FOR THE FUN PART.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE'RE GONNA TAKE IT UP WITH THE CRANE

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND DROP IT STRAIGHT ON ITS NOSE,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AS IF IT'S CRASHING INTO A WALL AT 35 MILES AN HOUR,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND FIND OUT WHAT KIND OF FORCES WE'RE GONNA GET.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: THE VERTICAL DROP...

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHOA! DIRECT HIT!

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

...IS A CURIOUS WAY TO CRASH CARS,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT WITH NO CHANCE OF A ROGUE RUNAWAY...

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

OH!

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

...OR A FLATTENED FENCE...

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Adam: NO, NO, NO, DON'T.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

...IT'S THE MOST RELIABLE RIG FOR A PARTY-BALLOON PILE UP.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ HORN HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Tory: SO, FIRST UP, WE ARE GONNA DO A CONTROL TEST

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WITH THE DRIVER BELTED IN AND THE PASSENGER NOT BELTED IN

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND SEE WHAT KIND OF G-LOADS WE GET.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, REMEMBER, THERE WON'T BE ANY BALLOONS IN THAT TEST.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

IN THE SECOND TEST, WE'RE GONNA DO THE EXACT SAME THING,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT THIS TIME PUT A BUNCH OF BALLOONS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

IN FRONT OF THE PASSENGER AND SEE WHAT DIFFERENCE THAT MAKES.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: AND DO TO JUST THAT,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THE GUYS FIRST NEED A COUPLE OF CLOWNS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHO, ONCE DRESSED TO KILL...

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

I'M MAKING HIM SMILE.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ LAUGHING ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: ...ARE PUT INTO THEIR RESPECTIVE HOT SEATS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHERE JUST LIKE THE MYTH, THE DRIVER IS BUCKLED UP,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

BUT HIS PASSENGER IS NOT.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

HOW COME THE CLOWN WOULDN'T WEAR A SEATBELT?

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THE FINAL PIECE OF THE PUZZLE IS TO ADD THE DATA SENSORS,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND THAT MEANS IT'S TIME TO GET SCIENTIFIC.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WHAT I HAVE HERE IS AN ACCELEROMETER.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, WE'LL HAVE TWO OF THEM.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

ONE WILL BE ATTACHED TO THE CLOWNS HEAD AND TO THE CHEST.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, WHEN THE CRASH HAPPENS,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

VOLTAGE WILL BE SENT TO THE DATA LOGGER,

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND THAT WAY, WE'LL BE ABLE TO RECORD THE EVENT.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THEN WE'LL LOOK AT THE DATA LATER

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND FIND OUT HOW MANY G's THE CLOWN ENDURED.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

A SURVIVABLE G-LOAD IS ANYTHING UNDER 100 G's.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

THAT'S OUR BENCHMARK.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

NOW, TO MEASURE THAT, WE HAVE OUR PCB ACCELEROMETERS

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

AND THE HELP OF OUR FRIEND DAVID FROM NATIONAL INSTRUMENTS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

[ HONKS ]

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Narrator: AND WITH THAT, EVERYTHING'S SET FOR LIFTOFF.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

Kari: SEND IN THE CLOWNS.

Narrator: NEXT UP, IT'S TIME TO CALL IN THE CLOWNS.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

NOW IT'S TIME TO RAISE THE CAR.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

THERE WE GO.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

WE CAUGHT A BIG ONE.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

Kari: WE'VE CALCULATED THAT IF WE RAISE THE CAR 41 FEET

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

FROM THE BUMPER TO THE GROUND,

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

WE CAN ACHIEVE A 35-MILE-PER-HOUR CRASH.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

ALL RIGHT, THIS IS CLOWN CAR CONTROL TEST.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

IN THREE, TWO, ONE...

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

Narrator: IN "TRENCH TORPEDO,"

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

ADAM AND JAMIE'S SMALL-SCALE TEST...

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

IT LOOKS A LITTLE BIGGER DOWN HERE.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

...HAS SHOWN THAT A SHARP CORNER CAN STOP A WATERY WAVE.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

THIS IS REALLY, REALLY COOL.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

Narrator: BUT HOW ABOUT AN EXPLOSIVE ONE?

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

WELL, THAT SEEMED TO WORK PRETTY WELL.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

MAYBE THERE IS SOMETHING TO THE TECHNIQUE.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

YEP, I THINK IT'S TIME TO BUILD SOME REAL TRENCHES

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

AND USE SOME REAL EXPLOSIVES.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

LET'S GET DIGGING. OKAY.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

SO, TO DIG THE DIRT ON THIS MYTH FULL SCALE,

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

THE GUYS MARCH TO A MEMORABLE LOCATION.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

Adam: WE'RE IN IONE, CALIFORNIA, TODAY,

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

AND I'M STANDING ON THE EXACT SPOT

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

WHERE WE ACTUALLY TESTED THE "DRAIN DISASTER" MYTH

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

OF ALL THINGS.

WE'VE GOT ALL OF OUR SENSORS IN PLACE.

WHOA!

TODAY, HOWEVER, WE'RE GONNA GO BACK IN TIME

WHOA!

AND DIG A BUNCH OF WORLD WAR I TRENCHES

WHOA!

AND SUBJECT THEM TO SOME ENEMY FIRE.

WHOA!

IT'S GONNA BRING BACK A LOT OF MEMORIES FOR JAMIE.

WHOA!

Narrator: LIKE IN THEIR SHOP TESTS,

WHOA!

THE GUYS ARE GONNA THROW TOGETHER THREE TRENCHES.

WHOA!

Adam: TRENCH NUMBER ONE.

WHOA!

Narrator: THE STRAIGHTAWAY, THE RIGID RIGHT ANGLE,

WHOA!

AND THE SHODDY SERPENTINE.

WHOA!

Adam: THAT LOOKS COOL.

WHOA!

Narrator: AND ONCE THEY'RE ALL MARKED UP, THE DIGGING CAN GO DOWN.

WHOA!

WHERE, THANKS TO SOME HEAVY MACHINERY...

...AND A TIME-LAPSED MONTAGE,

THEIR THREE 50-FOOTERS GET SUNK FAST.

...AND A TIME-LAPSED MONTAGE,

BUT THAT DOESN'T MEAN IT'S JOB DONE.

Adam: NOT MANY PEOPLE KNOW THIS,

BUT THAT DOESN'T MEAN IT'S JOB DONE.

BUT JAMIE'S FAMILY ARE COLOR FARMERS.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

THEY'VE BEEN FARMING COLOR LIKE THIS

BUT THAT DOESN'T MEAN IT'S JOB DONE.

ON SPECIALLY TREATED PIECES OF PLYWOOD

BUT THAT DOESN'T MEAN IT'S JOB DONE.

OUT IN THE FIELDS FOR YEARS.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

THIS IS TOTALLY NOT TRUE.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

NOT EVEN A LITTLE BIT.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

IN FACT, WE ARE COLOR-CODING OUR TRENCHES

BUT THAT DOESN'T MEAN IT'S JOB DONE.

SO THAT BOTH FROM A SEQUENCE AND NARRATIVE STANDPOINT,

BUT THAT DOESN'T MEAN IT'S JOB DONE.

YOU CAN CLEARLY SEE WHICH TRENCH WE'RE DOING AT A GIVEN TIME,

BUT THAT DOESN'T MEAN IT'S JOB DONE.

BUT ALSO EXPERIMENTALLY,

BUT THAT DOESN'T MEAN IT'S JOB DONE.

THEY'LL HELP YOU SEPARATE THEM IN YOUR MIND.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

Narrator: THE COLOR CODING DOES HELP TAILOR-MAKE EACH TUNNEL...

BUT THAT DOESN'T MEAN IT'S JOB DONE.

IT'S COMING ALONG NICELY.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

...BUT THE BOARDS ARE ALSO THERE TO SHORE UP THE SIDES.

BUT THAT DOESN'T MEAN IT'S JOB DONE.

Adam: WHY ARE WE SHORING UP THE SIDES?

WELL, REALLY SPECIFICALLY,

Adam: WHY ARE WE SHORING UP THE SIDES?

IT'S SO THAT WE GET PERFECTLY STRAIGHT EDGES

Adam: WHY ARE WE SHORING UP THE SIDES?

AND PRECISE CORNERS FOR OUR BLAST WAVE TO MOVE THROUGH.

Adam: WHY ARE WE SHORING UP THE SIDES?

THAT'S HOW WE'RE GOING TO ASSESS THE SOUL OF THIS STORY.

Adam: WHY ARE WE SHORING UP THE SIDES?

Narrator: OF COURSE, THERE'S ONE PART OF ONE TRENCH

Adam: WHY ARE WE SHORING UP THE SIDES?

WHERE STRICTLY STRAIGHT SIDES ARE NOT THE ORDER OF THE DAY.

Adam: WHY ARE WE SHORING UP THE SIDES?

Adam: THIS ONE -- THE IMPRECISE CORNER TRENCH --

Adam: WHY ARE WE SHORING UP THE SIDES?

WE ARE LEAVING UNCOVERED WITH THE WOOD ON THE CURVY PARTS

Adam: WHY ARE WE SHORING UP THE SIDES?

TO GET THE BIGGEST DIFFERENCE THAT WE POSSIBLY CAN.

Adam: WHY ARE WE SHORING UP THE SIDES?

ALSO, FOR VISUAL SYMMETRY,

Adam: WHY ARE WE SHORING UP THE SIDES?

WE'RE GONNA PAINT IT BLUE TO MATCH THE WALLS.

Adam: WHY ARE WE SHORING UP THE SIDES?

HERE WE GO.

Adam: WHY ARE WE SHORING UP THE SIDES?

WOW! WHOO-HOO!

Adam: WHY ARE WE SHORING UP THE SIDES?

YEAH!

Adam: WHY ARE WE SHORING UP THE SIDES?

Narrator: ADAM'S TICKLED PINK BY THE BLUE,

Adam: WHY ARE WE SHORING UP THE SIDES?

BUT WHAT'S MORE IMPORTANT

Adam: WHY ARE WE SHORING UP THE SIDES?

IS THAT WITH THAT, IT'S TIME TO BRING ON THE BOOM.

Adam: WHY ARE WE SHORING UP THE SIDES?

OUR TRENCHES ARE DUG.

THEY'RE SHORED UP.

OUR TRENCHES ARE DUG.

HECK, THEY'RE EVEN COLOR CODED.

OUR TRENCHES ARE DUG.

NOW, IT'S TIME FOR THE EXPLOSIVES.

OUR TRENCHES ARE DUG.

OUR BENCHMARK CONTROL TEST WILL BE THIS TRENCH --

OUR TRENCHES ARE DUG.

THE 50-FOOT-LONG STRAIGHT.

OUR TRENCHES ARE DUG.

IT SHOULD GIVE US A FANTASTIC IDEA

OUR TRENCHES ARE DUG.

OF WHAT HAPPENS TO A BLAST WAVE

OUR TRENCHES ARE DUG.

AS IT TRAVELS THROUGH EXACTLY THIS CONFIGURATION.

OUR TRENCHES ARE DUG.

AND WHEN WE'VE GOT THAT DATA,

WE'RE GONNA DO THE EXACT SAME TEST IN THIS ONE,

AND WHEN WE'VE GOT THAT DATA,

WHICH IS THE CLASSIC GERMAN SHARP-EDGED RIGHT-ANGLE TRENCH.

AND WHEN WE'VE GOT THAT DATA,

AND WE'LL COMPARE THE TWO.

AND WHEN WE'VE GOT THAT DATA,

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

THROUGH OUR SOFT-CORNERED SERPENTINE TRENCH,

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

AND IF THERE'S ANYTHING TO THIS STORY WHATSOEVER,

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

WHAT WE EXPECT TO SEE IS A HIGHER BLAST PRESSURE

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

WHERE I'M STANDING THAN IN THE CORRESPONDING SPOT

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

IN OUR HARD-CORNERED TRENCH.

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

ALL RIGHT, LET'S BRING ON THE EXPLOSIONS!

AND FINALLY, WE'LL BE SENDING AN EXPLOSIVE BLAST WAVE

Narrator: IT'S ENOUGH TO MAKE A CLOWN FROWN,

BUT CAN PARTY BALLOONS REALLY SAVE YOUR LIFE

Narrator: IT'S ENOUGH TO MAKE A CLOWN FROWN,

IN A 35-MILE-AN-HOUR FENDER BENDER?

Narrator: IT'S ENOUGH TO MAKE A CLOWN FROWN,

TO FIND OUT, THE MYTHBUSTERS CONTROL CAR

IS ABOUT TO CRASH LAND.

TO FIND OUT, THE MYTHBUSTERS CONTROL CAR

ALL RIGHT, ARE YOU READY TO DROP THE CLOWN CAR?

TO FIND OUT, THE MYTHBUSTERS CONTROL CAR

Kari: IN THREE, TWO, ONE...

TO FIND OUT, THE MYTHBUSTERS CONTROL CAR

WHOO!

I DON'T THINK THOSE CLOWNS SURVIVED.

WHOO!

Narrator: TO THE NAKED EYE,

WHOO!

THE 35-MILE-AN-HOUR HEAD-ON LOOKS HORRIFIC.

WHOO!

BUT SURVIVAL IS ALL ABOUT THE G-LOAD,

WHOO!

WHERE ANYTHING OVER 100

WHOO!

MEANS THERE'S BEEN A CLOWN CATASTROPHE.

WHOO!

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

THAT'S WELL OVER OUR BENCHMARK FOR FATALITY.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

BUT EVEN MORE INTERESTING,

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

THE PASSENGER THAT DIDN'T HAVE A SEATBELT ON OR AN AIRBAG

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

EXPERIENCED 630 ON THE CHEST AND 340 ON THE HEAD.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

THAT IS DEVASTATING.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

IT'S GONNA BE REALLY INTERESTING

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

TO SEE IF THE BALLOONS WILL HAVE ANY IMPACT ON THE NUMBERS.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

Narrator: SO, CUE CLOWN CAR 2.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

Tory: ANOTHER DAY, ANOTHER CLOWN CAR.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

LIKE THE CONTROL TEST, THE DRIVER CLOWN IS BUCKLED UP

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

WHILE THE PASSENGER ISN'T.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

YOU THINK THIS WIG ABSORBED ANY OF THE ENERGY?

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

Narrator: BUT UNLIKE THE CONTROL TEST...

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

TORY, IT'S FUN TIME!

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

DROP 2 WILL HAVE THE MYTHICAL BALLOON BARRIER.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

Kari: ALL RIGHT, NOW IT'S TIME TO PUT THE BALLOONS IN THE CAR.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

NOW, THE THEORY HERE

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

IS THESE BALLOONS ARE GONNA ACT AS AN AIRBAG.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

NOW, THE GOAL OF ANY AIRBAG

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

IS TO SLOW THE PASSENGER'S FORWARD MOTION

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

AS EVENLY AS POSSIBLE IN JUST A FRACTION OF A SECOND.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

I'M NOT SURE THESE BALLOONS ARE GOING TO FUNCTION THAT WAY,

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

BUT IT'S SURE GONNA BE FUN TO FIND OUT.

Kari: NOW, THE DRIVER WITH SEATBELT EXPERIENCED 150 G's.

ALL RIGHT, THIS IS CLOWN CAR DROP WITH BALLOONS.

ARE YOU READY?

ALL RIGHT, THIS IS CLOWN CAR DROP WITH BALLOONS.

OKAY, IN THREE, TWO, ONE...

ALL RIGHT, THIS IS CLOWN CAR DROP WITH BALLOONS.

NEGATIVE ONE!

ALL RIGHT, THIS IS CLOWN CAR DROP WITH BALLOONS.

[ GRUNTS ]

ALL RIGHT, THIS IS CLOWN CAR DROP WITH BALLOONS.

NOW THAT IS WHAT I CALL A PARTY.

I DON'T THINK THEY SURVIVED IT THOUGH.

NOW THAT IS WHAT I CALL A PARTY.

Narrator: ONCE AGAIN, THE CRASH WAS A SMASH

NOW THAT IS WHAT I CALL A PARTY.

AS THE PASSENGER PUSHED PAST THE BALLOON BARRIER

NOW THAT IS WHAT I CALL A PARTY.

AND WIPED OUT ON THE WINDSHIELD.

NOW THAT IS WHAT I CALL A PARTY.

ALL RIGHT, DAVE, THE BIG QUESTION ON EVERYONE'S MIND --

NOW THAT IS WHAT I CALL A PARTY.

DID THE BALLOON SAVE THE CLOWN'S LIFE?

NOW THAT IS WHAT I CALL A PARTY.

WELL, IN THE FIRST DROP WITH NO BALLOONS,

NOW THAT IS WHAT I CALL A PARTY.

THE PASSENGER SAW 340 G's AT THE HEAD, 630 G's AT THE CHEST.

NOW THAT IS WHAT I CALL A PARTY.

AND THE DROP WITH THE BALLOONS,

NOW THAT IS WHAT I CALL A PARTY.

THE PASSENGER SAW 350 G's TO THE HEAD, AND 620 AT THE CHEST.

NOW THAT IS WHAT I CALL A PARTY.

SO, THE RESULTS ARE PRETTY MUCH THE SAME.

NOW THAT IS WHAT I CALL A PARTY.

THE BALLOONS DIDN'T DO ANYTHING FOR HIM.

NOW THAT IS WHAT I CALL A PARTY.

ALMOST NO DIFFERENCE AT ALL.

NOW THAT IS WHAT I CALL A PARTY.

THANKS FOR YOUR HELP.

NOW THAT IS WHAT I CALL A PARTY.

COME ON, I'LL SHOW YOU MY BALLOON ANIMALS.

NOW THAT IS WHAT I CALL A PARTY.

WHOO-HOO!

NOW THAT IS WHAT I CALL A PARTY.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

IS NOT ENOUGH TO SAVE YOUR LIFE IN A CAR CRASH,

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

BUT IT'S NOT SUCH AN OUTLANDISH IDEA.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

AN AIRBAG IS AN INFLATABLE, AND SO IS A BALLOON.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

MAYBE THERE IS A BALLOON OUT THERE

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

OR A CONFIGURATION OF BALLOONS THAT WE COULD MAKE

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

THAT WOULD SAVE YOUR LIFE IN A CAR WRECK.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

Narrator: IN OTHER WORDS, THE MYTH MAY BE DOWN,

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

BUT BURST IT AIN'T.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

COMING RIGHT UP IN "TRENCH TORPEDO,"

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

THE HIGH-SPEED SHOTS THAT PUT THE AWE IN AWESOME.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

WOW.

Tory: SO, IT TURNS OUT AN AVERAGE BUNCH OF PARTY BALLOONS

WELCOME BACK.

ALL EPISODE LONG, WE'VE BEEN TESTING A MYTH FROM WORLD WAR I

WELCOME BACK.

THAT A SHARP-CORNERED TRENCH IS BETTER IN WARFARE

WELCOME BACK.

THAN A SOFT, ROUNDED-CORNER TRENCH

WELCOME BACK.

BECAUSE IT INHIBITS BLAST WAVES

WELCOME BACK.

FROM TRAVELING THROUGH THE TRENCHES

WELCOME BACK.

SENT BY EXPLODING MORTAR SHELLS.

WELCOME BACK.

WE ARE NOW AT THE FULL-SCALE PHASE OF THIS TEST,

WELCOME BACK.

AND WE HAVE A BUNCH OF BEAUTIFUL TRENCHES OUT HERE

WELCOME BACK.

IN GOLD COUNTRY IN NORTHERN CALIFORNIA.

WELCOME BACK.

WE HAVE SOME EXPLOSIVES IN OUR ARSENAL...

WELCOME BACK.

NICE.

WELCOME BACK.

YET ANOTHER USE FOR DUCT TAPE.

WELCOME BACK.

...AND ANY MINUTE NOW,

WELCOME BACK.

WE'RE GONNA START BLOWING SOME STUFF UP FOR SCIENCE.

WELCOME BACK.

Narrator: INDEED, BUT FOR TEST ONE,

WELCOME BACK.

THERE WILL BE A TORPEDO, BUT THERE WON'T BE A TRENCH.

WELCOME BACK.

RIGHT HERE IN THIS VERY SPOT,

WELCOME BACK.

SHORTLY WE'LL BE SETTING OFF 25 POUNDS OF TNT

WELCOME BACK.

AS OUR OPEN AIR, UNOBSTRUCTED CONTROL TEST.

WELCOME BACK.

WE'VE GOT SENSORS PLACED AT 10-FOOT INCREMENTS

WELCOME BACK.

BECAUSE SHORTLY AFTER THAT,

WELCOME BACK.

WE'LL BE SETTING OFF EXPLOSIONS IN THE TRENCHES

WELCOME BACK.

AND COLLECTING AND COMPARING SIMILAR DATA.

WELCOME BACK.

Narrator: IN OTHER WORDS, THE OPEN AIR BLAST

WELCOME BACK.

SHOULD GIVE THE GUYS A BONUS BENCHMARK.

WELCOME BACK.

[ CHUCKLES ]

ARE YOU READY?

ARE YOU THE KEYMASTER?

ARE YOU READY?

I AM THE KEYMASTER!

ARE YOU READY?

ARE YOU GOZER?

ARE YOU READY?

I'M GOZER, BABY.

ARE YOU READY?

ALL RIGHT. HERE WE GO.

ARE YOU READY?

ABOVE GROUND BLAST IN THREE, TWO, ONE...

ARE YOU READY?

WHOA!

I COULD FEEL THAT.

THAT WAS LIKE A REFRESHING BREEZE

I COULD FEEL THAT.

THAT LASTED A VERY SHORT PERIOD OF TIME.

I COULD FEEL THAT.

[ LAUGHS ]

I COULD FEEL THAT.

Narrator: IT SURE WAS A REFRESHING FLARE UP,

I COULD FEEL THAT.

AND THE GOOD NEWS IS THAT THE HIGH SPEED'S THE BOMB.

I COULD FEEL THAT.

LOOK AT THAT.

I COULD FEEL THAT.

WOW, THAT MIGHT BE ONE OF THE PRETTIEST ONES

I COULD FEEL THAT.

WE'VE EVER GOTTEN ON CAMERA.

I COULD FEEL THAT.

BUT THE BETTER NEWS IS THEY GOT THE DATA.

I COULD FEEL THAT.

20 FEET FROM THE BLAST

I COULD FEEL THAT.

AND PRESSURE WAS 39 POUNDS PER SQUARE INCH.

I COULD FEEL THAT.

30 FEET, IT WAS 12,

I COULD FEEL THAT.

AND BY 50 FEET, IT HAD DROPPED TO JUST 5.

I COULD FEEL THAT.

STRAIGHT TRENCH. YEP.

I COULD FEEL THAT.

BUT HOW WILL THOSE NUMBERS DIFFER

I COULD FEEL THAT.

ONCE THE GUYS GET DOWN AND DIRTY?

I COULD FEEL THAT.

THE MYTH OF THE CLOWN CAR CRASH...

NOW THAT IS WHAT I CALL A PARTY.

THE MYTH OF THE CLOWN CAR CRASH...

...IS SO FAR LOOKING LIKE BALLOON BALONEY.

THE MYTH OF THE CLOWN CAR CRASH...

BUT ALL IS NOT LOST.

THE MYTH OF THE CLOWN CAR CRASH...

ALL RIGHT, SO THAT DIDN'T WORK.

THE MYTH OF THE CLOWN CAR CRASH...

THE CLOWN PUSHED RIGHT THROUGH THE BALLOONS.

THE MYTH OF THE CLOWN CAR CRASH...

TRUE, BUT THERE ARE OTHER TYPES OF BALLOONS

THE MYTH OF THE CLOWN CAR CRASH...

THAN THE ONES THAT WE TESTED.

THE MYTH OF THE CLOWN CAR CRASH...

WELL, IT SOUNDS LIKE WE SHOULD DO SOME SMALL-SCALE TESTS.

THE MYTH OF THE CLOWN CAR CRASH...

MAYBE WE SHOULD TAKE A WEIGHT,

THE MYTH OF THE CLOWN CAR CRASH...

DROP IT ON DIFFERENT TYPES OF BALLOONS

THE MYTH OF THE CLOWN CAR CRASH...

AND SEE WHICH BALLOON DECELERATES THE WEIGHT THE BEST.

THE MYTH OF THE CLOWN CAR CRASH...

I LIKE IT.

THE MYTH OF THE CLOWN CAR CRASH...

Grant: SO FAR, WE HAVEN'T HAD ANY SUCCESS AT ALL

THE MYTH OF THE CLOWN CAR CRASH...

WITH USING BALLOONS AS AIRBAGS.

THE MYTH OF THE CLOWN CAR CRASH...

THEY JUST DON'T CUT IT.

THE MYTH OF THE CLOWN CAR CRASH...

SO WHAT WE NEED TO DO NOW IS LOOK AT BALLOONS

THE MYTH OF THE CLOWN CAR CRASH...

AND FIND OUT WHICH ONE ABSORBS THE MOST ENERGY,

THE MYTH OF THE CLOWN CAR CRASH...

AND TO DO THAT, I'M GOING TO BUILD A BALLOON-CRUSHING RIG.

THE MYTH OF THE CLOWN CAR CRASH...

Narrator: AND TO RUSTLE UP SAID RIG,

THE MYTH OF THE CLOWN CAR CRASH...

GRANT FIRST WRESTLES UP SOME GIANT METAL RINGS.

THE MYTH OF THE CLOWN CAR CRASH...

HULA HOOP ANYONE?

THE MYTH OF THE CLOWN CAR CRASH...

OW.

Narrator: WHICH ARE THEN WELDED TOGETHER INTO A TUBE.

OW.

IT'S SCIENCE!

OW.

BEFORE BEING PLASTERED WITH PLASTIC.

OW.

DONE.

Narrator: THEN JUST TWO THINGS REMAIN.

DONE.

A WOODEN DROP DISC WITH A DEAD-ON DIAMETER.

DONE.

GOOD.

AND AN EXPLANATION OF HOW ON EARTH IT WORKS.

GOOD.

SO THE BALLOON BASHER IS FINALLY FINISHED.

GOOD.

I'VE GOT MY POLYCARBONATE CYLINDER

GOOD.

WITH THE STEEL-REINFORCING FRAME.

GOOD.

I'VE ADDED THIS PLUNGER RIGHT HERE WITH THE 50-POUND WEIGHT.

GOOD.

NOW, THE IDEA IS THAT WE DROP THIS ONTO EACH TYPE OF BALLOON.

GOOD.

USING THE SAME WEIGHT

GOOD.

AND THE SAME VOLUME OF BALLOONS EACH TIME,

GOOD.

WE CAN COMPARE AND FIND OUT WHICH TYPE OF BALLOON

GOOD.

ABSORBS THE MOST ENERGY.

GOOD.

Narrator: WITH THE RIG AT THE READY,

GOOD.

THE TESTING CAN TUMBLE STARTING WITH THE CONTROL.

GOOD.

HERE WE GO.

GOOD.

THIS IS CONTROL TEST WITH NO BALLOONS

GOOD.

IN THREE, TWO, ONE...

GOOD.

OKAY.

OKAY, CONTROL IS 100 G's.

Narrator: NEXT, IT'S TIME TO BRING ON THE BALLOONS.

8...

Narrator: NEXT, IT'S TIME TO BRING ON THE BALLOONS.

BEGINNING WITH THE TYPE FROM THEIR EARLIER TEST.

Narrator: NEXT, IT'S TIME TO BRING ON THE BALLOONS.

15 AIR-FILLED LATEX BALLOONS.

Narrator: NEXT, IT'S TIME TO BRING ON THE BALLOONS.

IN THREE, TWO, ONE.

Narrator: NEXT, IT'S TIME TO BRING ON THE BALLOONS.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

BARELY CURTAILED THE CRUSHER AT ALL

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

AS THE ACCELEROMETER DATA ALMOST MATCHES THE CONTROL.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

NOW, WE'RE GONNA MOVE ON AND SEE WHICH IS BETTER --

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

DIFFERENT MATERIALS AND DIFFERENT SHAPES LIKE THIS.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

[ BARKS ]

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

Narrator: WITH NO BALLOON LEFT BEHIND, NEXT UP IT'S...

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

BALLOON ANIMAL!

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

Narrator: TO ENSURE A CORRECT COMPARISON...

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

LOOK AT THAT ONE.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

THAT'S NOT A FREAK OF NATURE AT ALL.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

...THE GUYS FILL THE CYLINDER TO PRECISELY THE SAME DEPTH.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

I'M MAKING A PTERODACTYL. [ SQUAWKS ]

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

BUT WILL THEIR CURIOUS CREATIONS...

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

OH, THAT'S A GOOD ONE.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

YEAH. IT'S AN OCTOPUS.

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

...LOWER THE G-LOAD AT ALL?

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

BALLOON ANIMAL IN THREE, TWO, ONE...

IMMEDIATELY, IT'S CLEAR THAT THE REGULAR LATEX BALLOONS

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

THAT WORKED BETTER THAN I THOUGHT IT WOULD.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

THIS IS REALLY COOL.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

LOOK, IT GOES FROM 100 TO 6.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

WE GOT 6 G's FROM THE BALLOON ANIMALS?

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

YEAH.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

WITH THE G-LOAD SLASHED SO SIGNIFICANTLY,

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

BALLOON ANIMALS MAY YET BE TOP DOG.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

BUT NEXT IT'S...

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

LITTLE BALLOONS.

[ CHUCKLES ] THAT WORKED PRETTY GOOD.

ALL RIGHT, SMALL LATEX PARTY BALLOONS.

THEY'RE SO ADORABLE.

ALL RIGHT, SMALL LATEX PARTY BALLOONS.

THREE, TWO, ONE.

ALL RIGHT, SMALL LATEX PARTY BALLOONS.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

Narrator: TORY'S RIGHT.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

THESE MINIATURE MARVELS DID SUCH A GOOD JOB

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

THAT THEY CUT THE G's TO JUST 2.8.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

BUT CAN THAT BE BETTERED WITH THE NEXT PARTY PITCH?

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

BIG BALLOON.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

Narrator: THE ADVANTAGE OF THESE BAD BOYS

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

IS THAT THEY'RE MADE OF A THICKER LATEX,

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

WHICH COULD LOWER THE LOAD.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

WAAHH!

OW!

WAAHH!

Tory: ALL RIGHT, GIANT PARTY BALLOONS.

WAAHH!

HERE WE GO, IN THREE, TWO, ONE...

WAAHH!

OH, MY GOD. COME LOOK AT THIS ONE.

LOOK AT THE OVERSIZE ONE.

OH, MY GOD. COME LOOK AT THIS ONE.

WE'VE GOT 2.

OH, MY GOD. COME LOOK AT THIS ONE.

I THINK WE HAVE A WINNER!

OH, MY GOD. COME LOOK AT THIS ONE.

I KNOW, ISN'T THAT CRAZY?

OH, MY GOD. COME LOOK AT THIS ONE.

THAT'S AWESOME!

OH, MY GOD. COME LOOK AT THIS ONE.

SO, NOW WHAT WE NEED TO DO IS TAKE THIS TO FULL SCALE,

OH, MY GOD. COME LOOK AT THIS ONE.

FILL UP A CAR, DROP IT, AND SEE IF IT SAVES A CLOWN'S LIFE.

OH, MY GOD. COME LOOK AT THIS ONE.

YEAH, NOW IT'S A PARTY.

WHOO-HOO!

YEAH, NOW IT'S A PARTY.

OW.

YEAH, NOW IT'S A PARTY.

PLEASE DON'T TRY ANYTHING YOU'RE ABOUT TO SEE AT HOME.

YEAH, NOW IT'S A PARTY.

WE'RE WHAT YOU CALL EXPERTS.

YEAH, NOW IT'S A PARTY.

IN THREE, TWO, ONE...

WHOA!

IN THREE, TWO, ONE...

Narrator: ADAM AND JAMIE'S OPEN-AIR BLAST

IN THREE, TWO, ONE...

IS BEAUTIFULLY DONE AND DUSTED,

IN THREE, TWO, ONE...

WHICH MEANS NOW, IT'S TIME TO DIG DEEPER.

IN THREE, TWO, ONE...

WE ARE TIED IN HERE.

IN THREE, TWO, ONE...

FIRST UP IS THE CONTROL TRENCH.

IN THREE, TWO, ONE...

HERE WE ARE.

IN THREE, TWO, ONE...

50 FEET OF GREEN STRAIGHTAWAY THAT'S ABOUT TO GET ROCKED.

IN THREE, TWO, ONE...

Jamie: ALL RIGHT.

IN THREE, TWO, ONE...

STRAIGHT TRENCH IN THREE, TWO, ONE...

IN THREE, TWO, ONE...

WOW!

THINGS ARE FALLING. YEAH.

[ Laughing ] MANY THINGS ARE FALLING FROM THE SKY.

THINGS ARE FALLING. YEAH.

THAT WAS SPECTACULAR.

THINGS ARE FALLING. YEAH.

Narrator: SPECTACULAR AND SPINE-CHILLING.

[ CHUCKLES ] OH, MAN.

Narrator: SPECTACULAR AND SPINE-CHILLING.

THEIR STRAIGHT AND TRUE TRENCH HAS BEEN WELL AND TRULY TRASHED.

Narrator: SPECTACULAR AND SPINE-CHILLING.

Adam: WELL, OUR FIRST TRENCH TEST WAS --

Narrator: SPECTACULAR AND SPINE-CHILLING.

I THINK THE WORD I'M GOING TO USE IS GANGBUSTERS!

Narrator: SPECTACULAR AND SPINE-CHILLING.

THE LEVEL OF DESTRUCTION IS

REALLY SHOCKINGLY HIGHER THAN I WOULD HAVE EXPECTED.

THE LEVEL OF DESTRUCTION IS

THE FIREBALL ITSELF

THE LEVEL OF DESTRUCTION IS

REACHED ALMOST 35 FEET DOWN THIS TRENCH.

THE LEVEL OF DESTRUCTION IS

IT IS -- IT'S HORRIFYING.

THE LEVEL OF DESTRUCTION IS

IT'S JUST HORRIFYING.

THE LEVEL OF DESTRUCTION IS

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

SUGGEST THAT THE BLAST WAS HARSH,

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

BUT WHAT DO THE PCB SENSORS SAY?

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

Adam: WELL, OUR PRESSURE SENSOR DATA FROM THE TRENCH TEST

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

IS VERY, VERY INTERESTING.

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

EDITORS, WILL YOU HELP ME OUT?

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

DRAW TWO LINES.

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

FANTASTIC.

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

LABEL ONE "TRENCH" AND ONE "ABOVE GROUND."

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

NOW PUT DOWN THE SENSOR DATA THAT WE GOT.

Narrator: BOTH THE HIJINKS AND THE HIGH SPEED

SEE THAT?

SEE THAT?

SEE THAT?

THE TRENCH SEEMS TO

SEE THAT?

HAVE AN AMPLIFYING EFFECT ON THE SHOCKWAVE.

SEE THAT?

IT'S SIGNIFICANTLY HIGHER IN THE TRENCH THAN ABOVE GROUND.

SEE THAT?

NOW, DOES THE SHAPE OF THE TRENCH

SEE THAT?

AFFECT THAT AMPLIFICATION?

SEE THAT?

WELL, THAT'S THE QUESTION, ISN'T IT?

SEE THAT?

Narrator: IN "PARTY BALLOON PILEUP,"

THE GUYS NOW KNOW THE BEST-CASE BALLOON.

Narrator: IN "PARTY BALLOON PILEUP,"

I THINK WE HAVE WINNER!

Narrator: IN "PARTY BALLOON PILEUP,"

SO CUE MORE CAR-CRASH CARNAGE.

Narrator: IN "PARTY BALLOON PILEUP,"

Tory: WE'RE GONNA RUN THE TEST THE EXACT SAME WAY.

Narrator: IN "PARTY BALLOON PILEUP,"

WE HAVE OUR TWO CLOWNS --

Narrator: IN "PARTY BALLOON PILEUP,"

ONE IN THE PASSENGER SEAT WITHOUT A SEATBELT,

Narrator: IN "PARTY BALLOON PILEUP,"

ONE IN THE DRIVER SEAT WITH THE SEATBELT.

Narrator: IN "PARTY BALLOON PILEUP,"

BOTH OF THEM WILL HAVE ACCELEROMETERS ATTACHED TO THEM.

Narrator: IN "PARTY BALLOON PILEUP,"

WE'RE GONNA TAKE THE CAR UP WITH THE CRANE,

Narrator: IN "PARTY BALLOON PILEUP,"

DROP IT FROM 41 FEET SO IT'S TRAVELING AT 35 MILES AN HOUR,

Narrator: IN "PARTY BALLOON PILEUP,"

LET IT CRASH INTO THE GROUND,

Narrator: IN "PARTY BALLOON PILEUP,"

AND SEE IF THE BALLOONS MAKE A DIFFERENCE.

Narrator: IN "PARTY BALLOON PILEUP,"

Narrator: REMEMBER,

WITH REGULAR LATEX BALLOONS,

Narrator: REMEMBER,

THE CLOWNS PEAKED AT 620 G's --

Narrator: REMEMBER,

SIX TIMES OVER THE LETHAL LIMIT.

Narrator: REMEMBER,

BUT FOR THIS TEST,

Narrator: REMEMBER,

THE GUYS AREN'T JUST OPTING FOR THEIR OPTIMAL THICK BALLOONS.

Narrator: REMEMBER,

I LIKE TO PUMP SOME HELIUM EVERY NOW AND AGAIN. YEAH.

Narrator: REMEMBER,

THEY'RE ALSO PACKING THEM IN AS TIGHTLY AS POSSIBLE.

Narrator: REMEMBER,

THIS IS LIKE HOW WE USED TO PACK FOR FAMILY TRIPS.

Narrator: REMEMBER,

Kari: TAKE HER UP.

Narrator: REMEMBER,

Tory: SO, WE'RE ABOUT TO DROP THE CLOWN WITH THE BALLOONS.

NOW REMEMBER, OUR BENCHMARK IS 100 G's.

Tory: SO, WE'RE ABOUT TO DROP THE CLOWN WITH THE BALLOONS.

WE NEED TO SEE THE BALLOONS DECREASE THE G-LOAD BELOW THAT.

Tory: SO, WE'RE ABOUT TO DROP THE CLOWN WITH THE BALLOONS.

IF HE GOES OVER 100 G's,

Tory: SO, WE'RE ABOUT TO DROP THE CLOWN WITH THE BALLOONS.

THE CLOWN IS DEAD AND SO IS THIS MYTH.

Tory: SO, WE'RE ABOUT TO DROP THE CLOWN WITH THE BALLOONS.

ALL RIGHT, THIS IS CLOWN CAR DROP

WITH OUR BEST LATEX BALLOON.

ALL RIGHT, THIS IS CLOWN CAR DROP

HERE WE GO IN THREE, TWO, ONE...

ALL RIGHT, THIS IS CLOWN CAR DROP

YEAH.

OH!

YEAH.

[ LAUGHS ]

OH, MY GOSH!

[ LAUGHS ]

I THINK IT MIGHT HAVE WORKED, MAN!

[ LAUGHS ]

I THINK THAT CLOWN MAY HAVE SURVIVED.

[ LAUGHS ]

Kari: WHAT A BEAUTIFUL SIGHT.

I SAW THAT CLOWN CAR DESCENDING TOWARDS THE EARTH,

Kari: WHAT A BEAUTIFUL SIGHT.

AND THEN I SAW THE HIGH SPEED.

Kari: WHAT A BEAUTIFUL SIGHT.

NOW, IN THE HIGH SPEED,

YOU ACTUALLY SEE THE CAR START TO COMPACT.

NOW, IN THE HIGH SPEED,

THE BALLOONS SEPARATE

NOW, IN THE HIGH SPEED,

JUST ENOUGH FOR A CLOWN FACE TO PEEK THROUGH

NOW, IN THE HIGH SPEED,

AND A CLOWN NOSE TO DUST THE WINDSHIELD

NOW, IN THE HIGH SPEED,

AND THEN START TO GO BACK INTO THE CAR,

NOW, IN THE HIGH SPEED,

AS IF THE BALLOONS ARE BOUNCING HIM BACK.

NOW, IN THE HIGH SPEED,

ALL RIGHT, BYRON, HOW'D WE DO?

DID EITHER GUY GET UNDER 100 G's?

ALL RIGHT, BYRON, HOW'D WE DO?

NOW, YOU REMEMBER

ALL RIGHT, BYRON, HOW'D WE DO?

HE SUSTAINED OVER 600 G's WITH JUST THE PARTY BALLOONS,

ALL RIGHT, BYRON, HOW'D WE DO?

BUT THIS TIME ONLY 130.

ALL RIGHT, BYRON, HOW'D WE DO?

WOW!

ALL RIGHT, BYRON, HOW'D WE DO?

THAT IS A HUGE REDUCTION IN THE G-LOAD,

ALL RIGHT, BYRON, HOW'D WE DO?

BUT STILL, 130 G's TO YOUR BODY --

ALL RIGHT, BYRON, HOW'D WE DO?

THERE IS NO WAY YOU'RE GONNA SURVIVE THAT.

ALL RIGHT, BYRON, HOW'D WE DO?

YEAH, UNFORTUNATELY,

ALL RIGHT, BYRON, HOW'D WE DO?

WE'RE GONNA HAVE TO CALL THIS ONE BUSTED.

ALL RIGHT, BYRON, HOW'D WE DO?

[ GRUMBLES ] TOTALLY BUSTED.

ALL RIGHT, BYRON, HOW'D WE DO?

I THOUGHT FOR A SECOND THERE

ALL RIGHT, BYRON, HOW'D WE DO?

IT HAD A GLIMMER OF HOPE.

ALL RIGHT, BYRON, HOW'D WE DO?

NOPE. STILL DEAD.

ALL RIGHT, BYRON, HOW'D WE DO?

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

THE OVERSIZED LATEX BALLOON,

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

WE WERE NOT ABLE TO SAVE THE CLOWN'S LIFE,

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

SO THIS MYTH IS BUSTED, BUT WE'RE NOT GONNA STOP THERE.

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

THIS IS "MYTHBUSTERS."

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

IT'S TIME TO RAMP IT UP,

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

SO WE'RE GONNA GO BACK TO THE SHOP

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

AND SEE IF WE CAN COME UP WITH

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

SOME KIND OF CONFIGURATION OF BALLOONS

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

THAT COULD SAVE THE CLOWN'S LIFE.

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

Narrator: IN THEIR EARLIER SHOP TESTS...

Tory: SO IT TURNS OUT EVEN WITH OUR BEST BALLOON,

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

...THE GUYS TESTED ONE BALLOON TYPE AT A TIME.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

BUT NOW, IT'S ANYTHING GOES.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

GET TO WORK.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

AS THE MYTHBUSTERS GO HEAD-TO-HEAD

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

IN A QUEST TO FIND THE ULTIMATE LIFE-SAVING BALLOON BARRIER.

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

FIRST UP IS KARI...

THEY MIGHT BE LITTLE, BUT MAN, THEY DO A GOOD JOB!

TOO MUCH.

TOO MUCH.

TOO MUCH.

Narrator: ...WHO'S MAKING

TOO MUCH.

WHAT CAN ONLY BE DESCRIBED AS A WIENER WHOOPEE CUSHION.

TOO MUCH.

THAT MIGHT WORK.

THIS GIANT, MASSIVE WEENIE BALLOON

THAT MIGHT WORK.

SHOULD TAKE CARE OF A COUPLE ISSUES WITH THE BALLOON AIRBAG.

THAT MIGHT WORK.

ONE, THEY WON'T SEPARATE,

THAT MIGHT WORK.

SO THE CLOWN CAN'T PUSH RIGHT THROUGH THEM

THAT MIGHT WORK.

WHEN HE ACTUALLY GETS IN THE CRASH,

THAT MIGHT WORK.

AND TWO, THEY'RE ALL A LITTLE UNDER-INFLATED,

THAT MIGHT WORK.

SO THAT YOU CAN'T POP THEM WHEN HE HITS THEM.

THAT MIGHT WORK.

BESIDES, MY CLOWN SENSEI ONCE SAID,

THAT MIGHT WORK.

"ONE BALLOON WEAK. MANY BALLOONS STRONG."

THAT MIGHT WORK.

Narrator: MEANWHILE, GRANT IS ALSO GOING FOR

THAT MIGHT WORK.

THE "MORE MEANS LESS" APPROACH.

THAT MIGHT WORK.

YOU KNOW WHAT THIS IS?

THAT MIGHT WORK.

THAT'S RIGHT.

THAT MIGHT WORK.

IT'S GIANT BUBBLE WRAP.

THAT MIGHT WORK.

Narrator: FINALLY, THERE'S TORY,

WHO'S COMBINING BALLOONS FOR A REAL KNOCKOUT.

Narrator: FINALLY, THERE'S TORY,

I THINK WE'VE GOT A WINNER HERE.

YES SIR.

I THINK WE'VE GOT A WINNER HERE.

ALL RIGHT,

I THINK WE'VE GOT A WINNER HERE.

NOW WHAT I'M GOING TO DO FOR MY BALLOON AIRBAG

I THINK WE'VE GOT A WINNER HERE.

IS TAKE THE GIANT LATEX BALLOONS AND THE MYLAR BALLOON.

I THINK WE'VE GOT A WINNER HERE.

WHAT I'M GONNA DO IS INCORPORATE THE TWO.

I THINK WE'VE GOT A WINNER HERE.

I'M GONNA STUFF THE MYLAR WITH THE LATEX BALLOONS

I THINK WE'VE GOT A WINNER HERE.

BECAUSE ONE THING I WANT TO DO IS KEEP THE BALLOONS TOGETHER

I THINK WE'VE GOT A WINNER HERE.

INSIDE THE MYLAR

I THINK WE'VE GOT A WINNER HERE.

AND HOPEFULLY THAT'LL SAVE HIS LIFE.

I THINK WE'VE GOT A WINNER HERE.

OKAY, WHO'S FIRST?

I SAY LADIES FIRST.

OKAY, WHO'S FIRST?

YOU WANT THE WEENIE WHOPPER WHOOPEE TO GO FIRST?

OKAY, WHO'S FIRST?

[ BOTH LAUGH ]

OKAY, WHO'S FIRST?

YEAH, LET'S DO IT.

OKAY, WHO'S FIRST?

OKAY.

OKAY, WHO'S FIRST?

Narrator: JUST LIKE LAST TIME,

OKAY, WHO'S FIRST?

KARI LOADS HER DESIGN TO THE FOUR-FOOT MARKER

OKAY, WHO'S FIRST?

AND THEN TAKES THE PLUNGE.

OKAY, WHO'S FIRST?

OKAY, HERE WE GO IN THREE, TWO, ONE...

OKAY, WHO'S FIRST?

OH, COME ON. THAT WAS SO DELICATE.

LOOKED PRETTY GOOD.

OH, COME ON. THAT WAS SO DELICATE.

BUT UNLIKE LAST TIME,

OH, COME ON. THAT WAS SO DELICATE.

THEY'RE NOT GOING TO DISCLOSE THE LOADS

OH, COME ON. THAT WAS SO DELICATE.

UNTIL EACH DESIGN HAS BEEN DROPPED.

OH, COME ON. THAT WAS SO DELICATE.

NEXT UP, TORY'S FOUR-HEART CORONARY DESIGN.

OH, COME ON. THAT WAS SO DELICATE.

YOU KNOW WHAT I THINK?

OH, COME ON. THAT WAS SO DELICATE.

I THINK IT'S GONNA GO... [ RASPBERRIES ]

OH, COME ON. THAT WAS SO DELICATE.

Tory: ALL RIGHT, THIS IS STUFFED BALLOONS.

OH, COME ON. THAT WAS SO DELICATE.

HERE WE GO IN THREE, TWO, ONE...

OH, COME ON. THAT WAS SO DELICATE.

THAT LOOKED REALLY GOOD.

YEAH.

THAT LOOKED REALLY GOOD.

Narrator: LAST, BUT NOT LEAST,

IT'S GRANT'S TURN TO GO DOWN.

Narrator: LAST, BUT NOT LEAST,

Grant: YOU GUYS READY FOR THE MAGIC?

Narrator: LAST, BUT NOT LEAST,

Kari: YEAH, SHOWTIME.

Narrator: LAST, BUT NOT LEAST,

IN THREE, TWO, ONE...

Narrator: LAST, BUT NOT LEAST,

[ BALLOON POPS ]

OH, WE GOT A COUPLE OF POPS,

[ BALLOON POPS ]

[ BALLOON POPS ] BUT HEY --

[ BALLOON POPS ]

[ LAUGHS ] MAYBE MORE THAN A COUPLE.

[ BALLOON POPS ]

ALL RIGHT. LET'S SEE WHAT WE GOT.

[ BALLOON POPS ]

Narrator: LIKE THE TWO BEFORE IT,

[ BALLOON POPS ]

GRANT'S RIG LOOKED RIGOROUS,

[ BALLOON POPS ]

BUT WHO WILL COME OUT ON TOP?

[ BALLOON POPS ]

OKAY, REMEMBER WE'RE LOOKING FOR A NUMBER UNDER TWO G's,

[ BALLOON POPS ]

WHICH IS WHAT OUR BIG BALLOONS GOT.

[ BALLOON POPS ]

MY CONTRAPTION WAS 3.8.

[ BALLOON POPS ]

CLOSE, BUT NO CIGAR.

[ BALLOON POPS ]

THAT'S A PRETTY GOOD SCORE THOUGH.

[ BALLOON POPS ]

NOT REALLY.

[ BALLOON POPS ]

YOU GOT 2.8.

[ BALLOON POPS ]

OH, CLOSER.

[ BALLOON POPS ]

AND GRANT, YOU GOT 1.7!

[ BALLOON POPS ]

HEY, THAT'S GREAT!

[ BALLOON POPS ]

NOW TO GO FULL SCALE.

[ BALLOON POPS ]

OH, WE GOT SOME WORK TO DO.

[ BALLOON POPS ]

SO, THIS IS OUR WINNING SCENARIO.

[ BALLOON POPS ]

IT REDUCED THE IMPACT ENERGY TO 1.7 G's.

[ BALLOON POPS ]

NOW WHAT WE NEED TO DO IS MAKE 15 OR 20 OF THEM

[ BALLOON POPS ]

AND STUFF THEM INTO EVERY PART OF THE CAR

[ BALLOON POPS ]

AND SEE IF IT SAVES THE CLOWN.

[ BALLOON POPS ]

Narrator: ON THE OTHER SIDE OF THE BREAK,

[ BALLOON POPS ]

PROBABLY BETTER IF YOU DON'T WATCH.

[ BALLOON POPS ]

THERE'S CLOWN CHAOS

[ BALLOON POPS ]

AND "TRENCH TORPEDO" HITS PAYDIRT.

[ BALLOON POPS ]

BYE-BYE!

[ BALLOON POPS ]

WHAT'S ALL THIS?

[ BALLOON POPS ]

I PROPOSE A DUEL.

[ BALLOON POPS ]

YOU, ME,

[ BALLOON POPS ]

PAINTBALL GUN EACH,

[ BALLOON POPS ]

ONE TRENCH EACH.

[ BALLOON POPS ]

LET'S SEE WHO CAN LAND THE FIRST SHOT.

[ BALLOON POPS ]

I'M THERE.

[ BALLOON POPS ]

[ CHUCKLES ]

JAMIE, ARE YOU READY?

[ CHUCKLES ]

I'M READY IF YOU ARE.

[ CHUCKLES ]

LET'S DO IT.

[ CHUCKLES ]

[ CHUCKLES ]

OH! MY HEART IS POUNDING.

OW.

TRUCE!

OW.

I HAVE A HIT ON MY HEAD.

OW.

I DID IT! THE WAR IS OVER.

OW.

WHOO!

OW.

Grant: SO FAR IN OUR "PARTY BALLOON PILEUP" MYTH,

OW.

NOTHING HAS BEEN ABLE TO SAVE THE CLOWN PASSENGER'S LIFE,

OW.

BUT WE ARE IN THE BUSINESS OF EXTREME.

OW.

THAT'S WHY WE HAVE THIS.

OW.

THIS IS SOMETHING I LIKE TO CALL BALLOON BUBBLE WRAP.

OW.

IT GOT THE LOWEST G-LOAD

OF ANYTHING WE TRIED IN OUR DROP TESTS.

IT GOT THE LOWEST G-LOAD

IT'S FESTIVE AND PROTECTIVE.

IT GOT THE LOWEST G-LOAD

Narrator: BUT WILL IT BE PROTECTIVE ENOUGH IN A 35-MILE-AN-HOUR HEAD ON?

IT GOT THE LOWEST G-LOAD

PROBABLY BETTER IF YOU DON'T WATCH.

IT GOT THE LOWEST G-LOAD

TO FIND OUT, THE GUYS STUFFED THE CAR

IT GOT THE LOWEST G-LOAD

SO IT'S LITERALLY FIT TO BURST.

IT GOT THE LOWEST G-LOAD

Tory: YOU GUYS ARE PACKED IN THERE LIKE SARDINES.

IT GOT THE LOWEST G-LOAD

THAT OUGHT TO DO IT.

Kari: NOW, WITH THIS LAST AND FINAL TEST,

THAT OUGHT TO DO IT.

WE'RE TRYING TO GET BELOW 100 G's ON OUR CLOWN.

THAT OUGHT TO DO IT.

THAT IS OUR BENCHMARK FOR SURVIVABILITY.

THAT OUGHT TO DO IT.

WE'VE ADDRESSED ALL THE PROBLEMS THAT WE'VE EXPERIENCED

THAT OUGHT TO DO IT.

WITH ALL THE OTHER BALLOONS.

THAT OUGHT TO DO IT.

WE HAVE SMALL BALLOONS ON SHEETS OF PLASTIC.

THAT OUGHT TO DO IT.

THAT WAY, THE CLOWN CAN'T

THAT OUGHT TO DO IT.

PUSH THROUGH THE MIDDLE OF BALLOONS

THAT OUGHT TO DO IT.

AND IF ONE LITTLE BALLOON BREAKS,

THAT OUGHT TO DO IT.

IT'S NOT GONNA CREATE A BIG CAVITY

THAT OUGHT TO DO IT.

WHERE THE CLOWN CAN ACTUALLY FALL INTO THE WINDSHIELD.

THAT OUGHT TO DO IT.

Narrator: IT'S A SOUPED-UP SOLUTION THAT'S DO OR DIE FOR THE MYTH.

THAT OUGHT TO DO IT.

IF THIS DOESN'T WORK, NOTHING WILL.

THAT OUGHT TO DO IT.

ALL RIGHT. HERE WE GO.

THIS IS BUBBLE WRAP,

ALL RIGHT. HERE WE GO.

IN THREE, TWO, ONE...

ALL RIGHT. HERE WE GO.

[ LAUGHS ]

IT DID NOT LOOK GOOD.

[ LAUGHS ]

LET'S GO CHECK THE DATA FOR THE "PARTY BALLOON PILEUP."

ALL RIGHT, SO HOW DID THE CLOWNS DO

WITH THE BALLOON BUBBLE WRAP?

ALL RIGHT, SO HOW DID THE CLOWNS DO

OKAY, SO THE PASSENGER'S HEAD PEAKED AT 220 G's

ALL RIGHT, SO HOW DID THE CLOWNS DO

AND HIS BODY AT 230 G's.

ALL RIGHT, SO HOW DID THE CLOWNS DO

WOW, SO THE CLOWNS ACTUALLY

ALL RIGHT, SO HOW DID THE CLOWNS DO

EXPERIENCED A BIGGER G-LOAD THAN THE PREVIOUS TEST.

ALL RIGHT, SO HOW DID THE CLOWNS DO

SO, PARTY BALLOONS

ALL RIGHT, SO HOW DID THE CLOWNS DO

ARE NOT A SUBSTITUTE FOR AIRBAGS OR SEAT BELTS.

ALL RIGHT, SO HOW DID THE CLOWNS DO

STOP CLOWNING AROUND.

ALL RIGHT, SO HOW DID THE CLOWNS DO

WANT TO KNOW WHY WE DID WHAT WE DID

AND DIDN'T DO WHAT WE DIDN'T?

WANT TO KNOW WHY WE DID WHAT WE DID

LOG ON TO discovery.com/ mythbustersaftershow

WANT TO KNOW WHY WE DID WHAT WE DID

AND FIND OUT.

WANT TO KNOW WHY WE DID WHAT WE DID

IN THREE...

Narrator: ADAM AND JAMIE'S STRAIGHT TRENCH TORPEDO...

IN THREE...

...HAS JUST GONE OFF WITH A BANG,

AND AS WELL AS A SENSATIONAL HIGH SPEED,

...HAS JUST GONE OFF WITH A BANG,

IT'S BLOWN UP SOME SURPRISING RESULTS.

...HAS JUST GONE OFF WITH A BANG,

SURPRISING BECAUSE WHEN COMPARED TO THE OPEN-AIR CONTROL,

...HAS JUST GONE OFF WITH A BANG,

IT'S CLEAR THAT THE STRAIGHT TRENCH

...HAS JUST GONE OFF WITH A BANG,

AMPLIFIES THE BLAST PRESSURE.

...HAS JUST GONE OFF WITH A BANG,

THE QUESTION NOW IS WHETHER A CORNER

...HAS JUST GONE OFF WITH A BANG,

CAN CAUSE THOSE NUMBERS TO DROP DOWN.

...HAS JUST GONE OFF WITH A BANG,

AND FIRST UP, IT'S THE PINNACLE OF GERMAN ENGINEERING --

...HAS JUST GONE OFF WITH A BANG,

THE SHARP-SIDED TRENCH.

...HAS JUST GONE OFF WITH A BANG,

Jamie: THIS IS THE TRENCH THAT THIS STORY IS ALL ABOUT --

...HAS JUST GONE OFF WITH A BANG,

THE ONE WITH THE SHARP CORNERS AND RIGHT ANGLES.

...HAS JUST GONE OFF WITH A BANG,

AND BASED ON EVERYTHING WE'VE SEEN SO FAR,

...HAS JUST GONE OFF WITH A BANG,

BY THE TIME THE BLAST WAVE GETS TO THE END OF THIS TRENCH,

...HAS JUST GONE OFF WITH A BANG,

PAST ALL THESE CORNERS,

...HAS JUST GONE OFF WITH A BANG,

IT OUGHT TO BE FAIRLY SMALL.

...HAS JUST GONE OFF WITH A BANG,

GOING DOWN.

...HAS JUST GONE OFF WITH A BANG,

Narrator: TO PUT JAMIE'S PREDICTION AND THIS MYTH TO THE TEST,

...HAS JUST GONE OFF WITH A BANG,

THE GUYS POSITION THE EXPLOSIVE PACKAGE...

...HAS JUST GONE OFF WITH A BANG,

ABSOLUTELY BEAUTEOUS.

...HAS JUST GONE OFF WITH A BANG,

...AND THEN DEPLOY FOR DETONATION.

...HAS JUST GONE OFF WITH A BANG,

Adam: ARE YOU READY FOR THIS?

...HAS JUST GONE OFF WITH A BANG,

ARE YOU GOZER THIS TIME?

...HAS JUST GONE OFF WITH A BANG,

I AM, KEYMASTER.

...HAS JUST GONE OFF WITH A BANG,

ALL RIGHT. CALL IT OUT.

...HAS JUST GONE OFF WITH A BANG,

RIGHT ANGLE SHARP-CORNERED TRENCH.

...HAS JUST GONE OFF WITH A BANG,

YEP.

...HAS JUST GONE OFF WITH A BANG,

IN THREE, TWO, ONE...

...HAS JUST GONE OFF WITH A BANG,

WOW!

[ CHUCKLES ]

I DON'T KNOW.

[ CHUCKLES ]

I THINK THERE'S GONNA BE A CRATER THERE.

[ CHUCKLES ]

I THINK THERE MIGHT BE.

[ CHUCKLES ]

LET'S GO LOOK AT IT.

[ CHUCKLES ]

Narrator: IT'S GOODBYE YELLOW-BRICK ROAD

[ CHUCKLES ]

AS THE BLAST TEARS THROUGH THEIR TRENCH.

[ CHUCKLES ]

BUT AT GROUND ZERO,

TO SAY THE GUYS ARE HAPPY IS AN UNDERSTATEMENT.

BUT AT GROUND ZERO,

[ LAUGHING ]

BUT AT GROUND ZERO,

WOW. DUDE, CHECK THAT OUT.

BUT AT GROUND ZERO,

I THINK THIS TELLS PRETTY MUCH THE WHOLE STORY

BUT AT GROUND ZERO,

'CAUSE THAT'S INTACT.

BUT AT GROUND ZERO,

EVERYTHING UP TO THAT POINT IS NOT.

BUT AT GROUND ZERO,

AS YOU CAN SEE, THIS IS THE SAFE END OF THE TRENCH.

BUT AT GROUND ZERO,

THE FURTHER YOU GO THAT WAY, THE WORSE IT GETS.

BUT AT GROUND ZERO,

NOW, MOST OF THE ENERGY SEEMED TO TRAVEL DOWN THE TRENCH

BUT AT GROUND ZERO,

AND APPEARS TO HAVE GOTTEN ABSORBED BY THESE CORNERS

BUT AT GROUND ZERO,

BASED ON HOW BADLY DAMAGED THEY ARE.

BUT AT GROUND ZERO,

BY THE TIME YOU GOT HERE, THERE'S NOT SO MUCH ENERGY LEFT.

BUT AT GROUND ZERO,

Narrator: AT 20 FEET, THE PSI WAS 60.

BUT AT GROUND ZERO,

AT 30 FEET, IT WAS 19,

BUT AT GROUND ZERO,

AND AT 50 FEET, IT WAS JUST 7.

BUT AT GROUND ZERO,

A COLOSSAL CONTRACTION FROM THEIR TUNNEL TRENCH.

BUT AT GROUND ZERO,

BUT THE MYTH SAYS THAT

BUT AT GROUND ZERO,

ONLY PRECISE CORNERS CAN SHELTER A SHOCKWAVE,

BUT AT GROUND ZERO,

AND TO FIND OUT JUST THAT,

BUT AT GROUND ZERO,

IT'S TIME TO END WITH ANOTHER BREATHTAKING BANG.

BUT AT GROUND ZERO,

WE'RE ABOUT TO SEND ANOTHER BLAST THROUGH ANOTHER TRENCH,

BUT AT GROUND ZERO,

AND I'M STANDING RIGHT WHERE THE RUBBER MEETS THE ROAD

BUT AT GROUND ZERO,

FOR THIS ENTIRE STORY.

BUT AT GROUND ZERO,

THIS IS WHERE WE WILL COMPARE

BUT AT GROUND ZERO,

PRECISION ENGINEERING VERSUS

BUT AT GROUND ZERO,

YOUR NORMAL WEAR AND TEAR OF A SOFT-CORNERED TRENCH.

BUT AT GROUND ZERO,

I THINK --

BUT AT GROUND ZERO,

MY INTUITION TELLS ME THAT THE SHARP CORNERS ARE BETTER

BUT AT GROUND ZERO,

AND THAT WE'LL SEE A HIGHER BLAST PRESSURE

BUT AT GROUND ZERO,

AT THE END OF THIS VERY TRENCH.

BUT AT GROUND ZERO,

BUT ONLY ONE WAY TO FIND OUT.

BUT AT GROUND ZERO,

Narrator: FOR THE FINAL TIME,

BUT AT GROUND ZERO,

THE GUYS SET UP THE PCB SENSORS...

BUT AT GROUND ZERO,

IT'S LOOKING A LITTLE TOASTY.

BUT AT GROUND ZERO,

...POSITION THE PROJECTILE....

BUT AT GROUND ZERO,

THERE YOU GO. [ GRUNTS ]

BUT AT GROUND ZERO,

...AND RETREAT TO SAFETY.

HERE WE GO!

THIS IS 25 POUNDS OF EXPLOSIVES

HERE WE GO!

IN A SERPENTINE, SOFT-CORNERED TRENCH.

HERE WE GO!

THIS IS FOR REAL. THIS IS FOR THE MONEY.

HERE WE GO!

THREE, TWO, ONE...

HERE WE GO!

BYE-BYE!

HERE WE GO!

NEVER GET USED TO THAT.

GOSH.

NEVER GET USED TO THAT.

Narrator: THE SERPENTINE SALVO WAS A BLAST.

NEVER GET USED TO THAT.

AND FOR JAMIE,

IT'S THE HIGH-CLASS HIGH-SPEED

AND FOR JAMIE,

THAT SEEMS TO TELL THE STORY.

AND FOR JAMIE,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

OF THE SQUARE-CORNERED AND ROUND-CORNERED TRENCH

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

ON SPLIT SCREEN.

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

OKAY,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

NOW IF WE LOOK AT THE FIREBALLS IN THESE TWO DIFFERENT TRENCHES,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

WE CAN SEE THAT IN THE SQUARE-CORNERED TRENCH,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

THE FIREBALL STOPS MOVING JUST AFTER THE FIRST CORNER.

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

HOWEVER, IN THE ROUND-CORNERED TRENCH,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

THE FIREBALL PASSES THE FIRST CORNER AND THE SECOND CORNER

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

BEFORE IT STOPS MOVING.

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

NOW, VISUALLY,

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

THAT TELLS ME THAT YOU'RE GONNA BE IN MORE TROUBLE

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

AT THE END OF THE ROUND-CORNERED TRENCH.

EDITORS, LET'S PULL UP THE HIGH-SPEED FOOTAGE

Narrator: AND THAT'S SOMETHING THAT

THE DAMAGE AT ROCK BOTTOM SEEMS TO AGREE WITH.

Narrator: AND THAT'S SOMETHING THAT

Adam: MORE DESTRUCTION.

Narrator: AND THAT'S SOMETHING THAT

HELLO!

Narrator: BUT WHAT DOES THE DATA DICTATE?

HELLO!

WELL, I THINK WE GOT SOME GOOD DATA.

HELLO!

I THINK WE DID.

HELLO!

LET'S GET BACK TO THE SHOP AND CRUNCH IT.

HELLO!

OKAY.

HELLO!

WHAT DO THE NUMBERS SAY?

I'M GLAD YOU ASKED.

WHAT DO THE NUMBERS SAY?

I HAVE PREPARED THIS TO EXPLAIN THEM.

WHAT DO THE NUMBERS SAY?

WHAT, DID YOU MAKE A CAKE?

WHAT DO THE NUMBERS SAY?

NO!

WHAT DO THE NUMBERS SAY?

THESE ARE OUR FOUR EXPLOSIONS,

WHAT DO THE NUMBERS SAY?

AND THESE NUMBERS REPRESENT

WHAT DO THE NUMBERS SAY?

THE BLAST PRESSURES WE GOT IN THOSE EXPLOSIONS.

WHAT DO THE NUMBERS SAY?

OKAY.

WHAT DO THE NUMBERS SAY?

THIS IS INTERESTING.

WHAT DO THE NUMBERS SAY?

YEAH, I CAN SEE THAT THE STRAIGHT TRENCH

WHAT DO THE NUMBERS SAY?

ALMOST LOOKS LIKE IT IS AMPLIFYING THE PRESSURES

WHAT DO THE NUMBERS SAY?

BECAUSE THEY'RE ALMOST 10 TIMES AS HIGH

WHAT DO THE NUMBERS SAY?

AS THE ABOVE-GROUND CONTROL TEST.

WHAT DO THE NUMBERS SAY?

ABSOLUTELY.

WHAT DO THE NUMBERS SAY?

AND CHECK OUT THE DIFFERENCE BETWEEN

WHAT DO THE NUMBERS SAY?

THE RIGHT-ANGLE TRENCH AND THE SERPENTINE TRENCH.

WHAT DO THE NUMBERS SAY?

IT'S CLEAR THAT THE NUMBERS IN THE SERPENTINE TRENCH

WHAT DO THE NUMBERS SAY?

ARE HIGHER THAN THE ONES IN THE RIGHT-ANGLE TRENCH.

WHAT DO THE NUMBERS SAY?

I THINK THESE NUMBERS TELL US THAT THIS MYTH IS PLAUSIBLE.

WHAT DO THE NUMBERS SAY?

SO IT IS.

WHAT DO THE NUMBERS SAY?

PLAUSIBLE!

WHAT DO THE NUMBERS SAY?
