Please, do not try what
you are about to see at home.

We're what you call experts.

Can't you tell?

On this episode of
"Mythbusters"...

Ohh!

Come to mama.

Yeah.

Now!
Aah!

Hello.

I'm talking to you from a bunker
two leagues below a building

Known to the public as m5.

Behind me, the Hyneman watches

Hundreds of feeds from
"Mythbusters" of years past

But not out of narcissism.

No, this has a purpose.

The powers that be have allowed
the Hyneman

To sift through

All the constructions that
he's done over the past 10 years

To find one
that he found unsatisfying

And wants to revisit,

One that will bring a smile,
an invisible smile

Underneath
his prodigious moustache.

Would you shut up?

Yeah, can it, Adam,

Because this episode

Is all about second chances.

With over a decade of episodes
and 850 myths to choose from...

Two... One.

They've scanned the archives

For their greatest,
unsolved myth-teries.

Adam and Jamie have
a blast from the past...

Whoa!
...As they mix

Dynamite and diy once again.

Oh, what modern inventions
will we come up with next?

But can they deck the walls...

I call this
my psychedelic spring.

And paint a room with a boom?

Congratulations.
You finally made the death star.

Go.

Meanwhile,
Kari, Tory, and Grant...

Ha-ha!
- It floats.

Are fulfilling a fan fantasy...

Oh, this is gonna be
so awesome.

Going full steam ahead
to split a boat...

Mythity split it.
...Testing first by sea...

Come on, come on,
come on, come on!

Oh!

And then on land.

This is it, man.
Three, two, one!

But can they finally
splinter their timbers...

And tear a boat in two?

If there's one thing I like,
it's fast.

Who are the Mythbusters?

Adam Savage...

I reject your reality
and substitute my own.

And Jamie Hyneman.

It's almost too exciting.

Between them, more than 30 years
of special-effects experience.

Together with Grant Imahara...

This is why we can never have
anything nice.

Kari Byron...

Science gets more fun when I get
a bigger gun.

And Tory Belleci.

Say hello to my little friend!

They don't just tell the myths.

They put them to the test.

First, Adam and Jamie
are brushing up

On their arts and blasts.

For those of you
playing at home,

"painting with explosives"
is a show we did years ago

Based on an episode of
the british comedy "mr. Bean"...

In which a stick of dynamite
is placed in a bucket of paint.

And when it blows up,

It perfectly paints
the room it's in

Without destroying the room.

Yeah, but our explosives

Didn't do a very good job of it,
did they?

No.

I think we ended up more, like,

Staining the walls
than actually painting them.

Yeah, it was a jackson pollack
sort of a moment.

Yeah. Barely.

Yep.

The last time we tested this
weapon of mass decoration...

One.

Our painters and detonators...

Coverage... total crap.

Got paint on the walls...

That's horrible.

But you wouldn't call it
home improvement.

So, you think you can
actually do it this time?

You have a new design in mind?

Well, I'd like to try.

And as you know, I have a thing

About actually harnessing
the power of explosives

To do work instead of
just blowing crap up.

I have some ideas of my own.

Let's say, for this episode,

We go off to our separate
corners and each try a solution

And see if we can't
finally achieve

Painting with explosives.

Sounds like fun.
All right.

Boom.

So, the guys will split up

And each craft
their own room boom.

But that's going to take
some bomb-range r and d.

What a lovely day.

Let's blow something up.

And first
to take up the brush is Adam.

I'm going
all the way back to basics.

I'm gonna take
a little chunk of c-4

And a bag of paint
and a surface,

And I'm gonna blow up the c-4

And watch what it does
to the paint on the surface.

So, Adam's plan
is to start small...

C-4 goes here.

Paint hangs here.

My test canvas goes here.

Under the watchful
eye of j.D. Nelson

To explore what happens

When paint meets explosive
meets canvas.

Painting with explosives.

First experiment
in three, two, one, go.

Fascinating.
Fascinating.

It just, like, goes,
"pbht."

"pbht."

That's not at all
what I expected to happen.

That's information.

That was the whole point
of this test.

That fraction of coverage

Is a long way
from what Adam needs...

Boom. Pbht.

And the action replay
reveals why.

Whoa.
The paint's still there.

Wow.

It's totally not vaporizing.

Its' too far away.

That is radical.

Awesome. Okay.

I know what to do next.

Yep.

For test two, Adam's got

Something different
on his plate.

So, the difference between
this blast and the last one

Is that I am going to move
the paint much closer...

In fact,
right on top of the c-4...

And second, as you probably
already surmised by this,

I'm going to give the c-4
a reflecting backing plate,

This big, heavy piece of steel.

Oh, cool.
There it is.

There you go.

I'm not actually sure
if this is gonna work,

But it's gonna be really
different than the last one,

And that's gonna
tell me something.

In three, two, one, go.

Whoa!

That was far more effective.

The backing plate
certainly reflected the paint

Onto the board
and everywhere else.

There we go.

Hi, there.
How you doing?

Hi.

The high-speed shot
of my blue-paint explosion

Is absolutely gorgeous.

I got exactly the vaporized fog
of paint that I was looking for,

And most of it ended up
on the four-by-eight of wood

That I had placed there
to receive the paint.

It's about as far as you'd get

If you wanted to roll
that much paint onto that board.

And that's exactly the kind of
coverage Adam was looking for.

But he still thinks
he can improve on it.

In this test,
I'll be using this.

It's actually a thin sheet
of plasticized, sheet explosive,

Sort of a c-4 jerky,
if you will.

But don't eat it!

No. I'm gonna paint with it.

But will spreading
the explosive under the paint

Also spread the coverage?

All right, here we go.

Final explosion
in three, two, one, go.

That was more powerful
than I expected it to be.

That was
a little too much oomph.

Well, let's go see how it did

With the painting anyway.

It was less a lick of paint
and more a riot of color.

That goes there.

But piecing back together
his canvas has inspired Adam.

Well, for me, that was a very
successful and excellent day

And not just because I spent
the day blowing stuff up.

Because in blowing stuff up,
I actually learned...

I believe I learned
everything I need to know

To paint with explosives,

Including
how much explosives is too much.

Time to get to work.

So, Adam heads back to the shop,

Where another Mythbuster has
been playing with his nozzles.

The way I see it, if I can get

A single blast of paint
going through a nozzle

To cover an entire wall
perfectly evenly,

Then if I have multiple nozzles
painting multiple walls,

I can get
a single blast of paint

To paint a whole room.

I'm thinking that this
sort of flattened orifice here

Is restricting the paint

To where
it doesn't come out in a cone,

But rather,
it comes out in a rectangle.

And that's exactly what I need.

It's exactly what he needs.

But a hose
is a long way from an explosion.

With that in mind,

I've broken out this rig
that I built some time ago

Because it'll allow me to test
with up to about 700 p.S.I.,

And we'll see
if that fans it out more.

Jamie's aiming

For a rectangular spread
onto the wall.

Too far open.

But it's a delicate business

Of tweaking his nozzle
just so...

I liked the first one better.

Until eventually,
he finds his goldilocks ratio.

Three, two, one.

It's looking pretty good.

Yep,
and with his nozzle in hand,

Jamie heads to the bomb range...

To put part two
of this theory to the test.

Solid as a rock.

My theory
is that this time around,

We need to contain
the paint and the explosives

In something like
this high-pressure, scuba tank,

And when the explosives go off,

The paint will be propelled
out the nozzle of the tank

Kind of like a spray nozzle.

And we'll end up with
our nicely painted wall,

Hopefully not a pipe bomb.

Yep.

Jamie's method
all comes down to pressure.

But first, what happens

When you put explosives
inside a tank of paint?

All right.

This is test one, c-4,
no nozzle,

In 3, 2, 1, go.

Ah.

That...
that actually is quite nice.

It looked like
it sent most of the paint out.

No rupture.

It didn't blow,

So tank two is filled with paint

And then fitted with
the patented, Hyneman nozzle.

But will the combo
of rectangular nozzle

And pressurized paint
cover the wall?

In three, two, one.

Uh, well.

Once again, the tank survived,

But the nozzle doesn't seem

To have made
any difference to the coverage.

We're pushing the limits

With what we can get
with these tanks,

And the fact is that
I'm not creating

The kind of spread that I need.

I need more pressure
to get that spread.

So, I think
it's back to the drawing board.

Later, can the Mythbusters make
high art with high explosives?

Go.

Oh, my gosh.

And Kari, Tory, and Grant
weigh anchor on water.

Mythity split it.

But will the curse
of the bifurcated boat return?

The Mythbusters
have been testing, confirming,

And busting for over 10 years.

And now they're closing the case
on some unsolved myth-teries.

Now, if you guys
don't remember the story,

It goes like this.

A man is driving his speedboat
out of control

And crashes
into a channel marker,

Almost splitting
the boat in half.

Now, he tells
the insurance company

That he was only traveling
at 25 miles an hour.

When we tried it,
we couldn't split the boat.

We couldn't even get a tear.

Yeah, our results
were less than spectacular.

But according to you fans,

That's because our methodology
was totally wrong.

Because we didn't do it
on water.

Exactly. So, right here, right
now, we are gonna retest it.

We're gonna kill
two birds with one stone.

It was the myth
they said was cursed.

But despite the rain...

I'm pretty much over this one.

The problems...

Did we lose the cable?

The arguments...

Dude, we never use
the blue rope.

We always use the blue rope!
No, we haven't.

And the accidents...

Yeah!
Whoo!

Ohh!

The guys
could never split the boat.

Oh, the story's busted at 25.

However, the fans say
this land-loving test...

Was a flub.

All right. 10-year take 2.
What's the plan?

Well, it's obvious.

We have to test this on water
just like the fans asked.

Well, we need a boat
and a channel marker,

But how
do we get the two to crash?

Why don't we do it
the same way?

This time,
we just use powerboats.

You make it sound so easy.

Now we're older and wiser.

We are older.

Yep.

Although the myth is the same...
crash a speedboat

At 25 miles an hour
into a channel marker...

Instead of testing
on the runway,

They'll float their boat
on a lake.

And rather than using
a tow truck,

They'll use a pair of towboats.

So, to weigh anchor on water...

It's off
to big break marina in oakley.

So, that's the boat.

Oh, that is awesome.

There she is.

That brings back memories...
and not all of them good.

Now, remember, we have to crash
our boat into a channel marker.

Now, as you can see,
this marina is filled with them.

But for some reason,

They don't want us
to crash our boat into theirs.

So, we need to plant our own.

Now, this is no easy job.

I mean, we're talking about
a 40-foot pole

Being sunk
12 feet into the ground

While on top of the water.

And luckily for us,
rob, our friend here,

Has a floating pile driver.

Indeed.

And with rob driving

Our pole into the delta...

It's time to shape up
and ship out.

We've removed the engine
just like last time,

So we're going to replace

The equivalent weight
of the engine

With barrels full of water.

And with the barrels aboard,
it's time to hit the waves.

Check for holes.

Step one, it floats.

It floats.

And now to give it

The equivalent ballast
of an engine.

But to get it moving on water,

It's gonna need help.

These are our towboats.

That's right.
You heard me. Two boats.

Because there's too much
water resistance for just one.

Each of these boats has
a 175-horsepower engine.

That should be plenty of power

To get our speedboat
up to 25 miles an hour.

Up to 25 miles per hour...

Aaaagh!

And into the newly installed,
picture-perfect channel marker.

Before we rig all the important
components to this experiment,

I thought we needed
a little authenticity

And make this look
just like the viral photo.

And with the tow system working,
they're ready to test.

But while the cameras reset...

What the Oh, no!

Oh

Tragedy strikes.

You're probably wondering why

There's a giant barge
in the middle of our channel,

And we were wondering
the same thing.

And then, that barge

Got closer and closer
to our channel marker,

And it actually
knocked it over into the water.

In fact, our crew, right now,
is looking for it,

Trying to fish it out.

Did you guys find it yet?

Not yet.

This is so "Mythbusters."

I mean, everything was going
so smoothly.

Something had to go wrong.

But unlike the marker,
this myth ain't sunk yet.

Could painting be as easy as
"three, two, one, boom"?

Well,
when the Mythbusters tried this,

Their tnt diy was d.O.A.

I thought it would be
a little better than that.

Now, armed with seven years'
more explosives experience,

Their first stop
was painting and detonation 101.

That's information.

That was the whole point
of this test.

And back at the shop,

Jamie's "tankful"
for all that research.

Having seen this tank darn near
rupture from an explosion

Points out the fact that
when an explosive goes off,

The energy from it

Wants to travel outward evenly
in all directions.

It's almost
a spherical swelling.

So, you know,

Maybe a cylindrical tank
isn't the way to go.

Maybe we need a spherical tank.

But the problem is

That you can't just
go to the store and buy one

Like you can a scuba tank.

You got to make your own,
and that's not a simple task.

Not a simple task,

But the Hyneman mind
will find a way.

In fact,
it looks like he already has.

Jamie's thought up an ingenious,
flat-pack design

For his spherical tank.

There we go.

24 one-inch-thick washers

And 26 assorted other parts
to bolt it all together.

Looks like it ought to weigh
around 3,500 pounds.

That's a big, heavy sphere.

Yep. That's no moon.

So, it's off
to get those washers plasma cut

And then put it all together.

So, when this is all assembled,
it should hold

Upwards of 50,000 p.S.I.
From the blast.

At least, that's the plan.

That's the plan,
but with over 50 parts

All cut from one-inch,
heavy-duty plate...

this thing's a beast.

That's one giant, 3-d puzzle.

But as it's a brainteaser
of his own design,

Jamie has
this riddle wrapped in an enigma

All figured out.

The sphere's being made
in two halves,

And each half is basically

A stack
of different-sized washers

That get put
on top of each other

And welded together.

Now, the holes leave

A 10-inch-diameter cavity
in the middle of this sphere,

And that's where
the paint and the dynamite goes.

There we go.

Now,
when the explosive goes off,

All of that paint
has got to go somewhere,

And so, I'm hoping that it'll go

Right into these sort of
funnel shapes in these nozzles

And straight out
and paint our walls.

What it actually will do
as far as painting a house,

I'm not really sure,
but I'm having a ball.

Get it?
He's having a ball.

And as he works
long into the night,

It's clear Jamie's sphere
has turned to the dark side.

You know, if you want
to contain a high explosive,

That's what you got to do.

That's pretty.

Well, while Jamie's working on

Whatever flower of death
he's building

Back there behind the forklift,

I have been thinking seriously

About the explosions that I got
out on the bomb range.

Oh. Right.

So, they have given me
the ideas that I need.

I've got all the steel cut.

I'm about to start constructing

My painting device
here in the shop.

Yep.

And just like the Hyneman,
Adam's device ain't simple.

There's a lot of moving parts
to this painting rig,

But it's gonna be cool.

Adam welds some frames,

And then... well, we're not
quite sure what he's doing.

Whew!

Coming along.

And that's exactly
how he wants it to stay.

All right.

At this point, I'd like you
to take a moment and speculate

On how you think
my painting machine works.

'cause you know what's cool?

You're totally wrong.

I'm going way off
the reservation on this one.

Oh, what modern inventions
will we come up with next?

So, with Adam's secret device
apparently complete

And Jamie's giant death sphere
on the back of the truck,

The war on walls can begin.

Three, two, one, go.

At the big break marina...

What the

Oh, no!

There's been a big barge break.

And it seems as though

The bifurcated-boat curse
is back.

Ah, good, old, bifurcated boat.

In the great tradition
of the mythity split,

This is a completely cursed
experiment.

We lost our channel marker
to that barge.

But luckily,
we've procured another.

The bad news is we do lose
a little authenticity

As our seagull and our sign
are at the bottom of the lake.

Go ahead, Tory.
Back it in.

Yep,
with 10 years of experience,

Our crew certainly knows
how to salvage a myth.

And thanks to their quick
thinking and resourcefulness...

I feel like
we've done this before.

'cause you have.

Pole two is good to go.

And now that the fans
are getting their watery way,

Just how much difference
will testing in the drink make?

So, what's the big deal
with water?

Well, here's why
it might make a difference

Doing it on water this time.

The boat
is sitting on the water.

Water is incompressible.

That means that there's pressure
on the hull.

That extra pressure
might translate

Into more impact force
on the bow,

Potentially
allowing it to split.

Second reason is that
the keel is now in water,

Helping
to keep the boat straight,

So you avoid possibly getting
a glancing blow.

Now, why might it not make
a difference?

Well, think about it.

The weight of the boat
is the same.

The speed is gonna be the same.

Therefore, we're gonna have
the same amount

Of kinetic energy
hitting that pole.

What do I think is gonna happen?

I don't think we're gonna get
a split, at least not at 25.

Grant's skeptical,
but after their cursed morning,

Tory is hoping they can
actually push the boat out.

All right,
there should be one word

Going through
your guys' heads right now,

And that's "bifurcation."

But will testing
this myth afloat split the boat?

All right.
The boat's in place.

Channel marker's up.

This is bifurcated boat,
take two.

Mythity split it.

In three, two, one, hit it.

The towboats accelerate...

And the mythity split
takes off...

there's the boat.

Oh, the rope's tensioning!

Boat's away.
Oh, here it comes!

Wow.
Okay.

Slowly speeding up

To the mythical
25 miles per hour.

Here comes the boater!

That looks so crazy.
Ghost boat!

Oh, it's beautiful.

But will the channel marker
finally make its mark?

Come on, come on,
come on, come on!

Come on!

Here it comes!
Headed straight for the pier.

What the heck?!

We just took the pillar down!

That was the wrong thing
to split.

The marker just got split.

I didn't see that one coming.

I didn't, either.

I didn't see that coming,
either.

That's not how it happened
in the myth.

That's a good shot, though.
It hit it right on the bow.

It did not
split the boat in half.

That is the most important
thing.

That's the important thing.

Important because in that
shocking, split-second impact,

The tables on this myth turned.

The marker bifurcated,

And the mythity split refused

To live up to its name
once again.

So, the whole reason
for this revisit

Is that fans said
that without water,

Our original tests were invalid.

You know what?
They were right.

See, the resistance of the water
kept the boat

Going straight on impact
without glancing off.

However,
the energy of the impact

Caused the pole to break
and not the boat.

So ultimately,
it's the same result...

A busted myth.

Just a slightly different way
of getting there.

Now, they say

That two of the happiest days
of a boat owner's life

Is the day he buys the boat
and the day he sells it.

But I won't be happy until
we cut that boat in half.

Yep.

It ain't over
until the mythity split splits.

One.

Can you paint a room
with a boom?

Well, after a little
trial and error...

Looks like I need a little bit
more work on my nozzle.

Each of the Mythbusters have
come up with a plan to find out.

Down at the range,

It's time to test
the state of their art.

I don't know
what Adam's been up to,

But I've had my hands full
building my paint bomb,

And I didn't have time
to build a room to paint.

So, we brought in
a team of carpenters,

And they put this

8-foot-high-by-12-foot-square
room together

As our blank canvas.

The canvas is primed.

Here we go.

But strangely,

Adam's not unloading his device
anywhere near it.

Allow me to introduce
the snowflake,

My painting machine.

It is named after both

Its hexagonal design
and its uniqueness.

And its design is informed
by exactly what I learned

Out here on the bomb range
earlier this week.

And this is the result.

Some might feel like

I have broken the rules
with this design.

Clearly, Adam's up to something.

All right. Good.

And as he welds

The final touches
to the snowflake,

Jamie's confused.

I'm guessing
the paint goes in the middle.

Yep, right along with
the explosives.

So these things are in the way.

What? Are they supposed to
disperse the paint or something?

Nope.

These panels are exactly
where I want them to be.

Well, how are you gonna paint
the house?

I'm not gonna paint the house.

I'm going to paint art
that goes in the house.

Oh.

"paintings" with explosives.

Yeah.

I thought I'm the one
that's supposed to cheat.

Yeah, I thought I'd steal
your thunder this time.

Usually,
it's the underhanded Hyneman

Who decides to bend the rules...

Hey, hey!

And stack the odds
in his favor.

But after 10 years...
And that's for you.

Clearly,
all that devious designing

Has rubbed off on Adam.

Well, this all started when
I was out here at the bomb range

Doing my preliminary tests
with painting and explosives.

I really,
really liked the patterns

That I was getting
on my target board.

And I thought,
"what if we made art?"

I'm still technically
"painting" with explosives.

I just figured
Jamie was gonna go whole hog

On getting that room
covered with paint,

And I could
kind of do my own thing.

And that's what I did.

Now it's time for the snowflake

To make its kinetic art debut

With six marbles of c-4
and some paint.

I call this
my psychedelic spring.

I'm ready to go.
Let's get to safety.

All right.

You ready, sir?

I'm ready.
All right. Here we go.

Painting with explosives

To make some art
in three, two, one.

Wow, that was quick.

It was quick.

But when you slow the explosion
to 1,000 frames per second...

Wow. That is insane.

It's also beautiful.

That's a piece of art
in and of itself.

Look! It's like
a clown's head exploded.

That is the loveliest thing

I have ever seen.

But did that explosive
pop of color create pop art?

That's beautiful!

All right.
There's one.

Oh. Oh, it's gorgeous!

That's beautiful.

The tale of destruction
wreaked on the canvas.

As Adam
canvasses his canvases...

Oh, yeah.

That's really nice.

It's clear that all six
were mostly covered with paint.

Well,
I don't know much about art,

But I know I like
making it with explosives.

Hey, well, two of them
have some nice colors going.

They show some promise.

Maybe... maybe you could take
an art class or something.

What do you think?

I'm very pleased.
I'm very pleased.

But while the results

Of Adam's art deco
are a little muddy,

It's the process
that was beautiful.

Nice. Can't wait to see
what Jamie comes up with.

Top that, Hyneman.

Next, will a rocket sled

Close the case
on this unsolved myth-tery?

This is it, man.

Hopefully,
we can cut this boat in half.

And can Jamie's paint ball
deck the wall?

I'd like to watch
this one from the bunker.

Do not try what you are
about to see at home.

We're what you call experts.

Rocket-sled track.

You guys ready for this?

If there's one thing I like,
it's fast.

Let's do it.

When we want to fly a wall down
a track and pulverize a car,

When we want to cause

A rear-end collision
at nearly 400 miles an hour...

that was one of the coolest
things I've ever seen!

We come here

Because, "A", there's no one
around to get in harm's way,

And, "B", nobody does extreme

Like our friends
at new mexico tech.

And today
is gonna be no exception.

So, why are we taking it
to these extremes

And using a rocket-powered sled?

Well, we tested
the myth just like it stated,

Crashing a boat at 25 miles
an hour into a channel marker,

But we couldn't
get it to split in half.

So, the myth is busted.

But now it's my favorite part
of the show,

Where we replicate the results.

Now, if it's worth doing,
it's worth overdoing,

and I would have to say
this is overdoing.

Now, this is the boat
that we're going to use.

It's not the exact same boat
as the one in the myth,

But it's gonna do just fine.

It will be weighted the same.

It's made of the same materials.

And the center of the bow

Is still hitting
the center of the pole.

There's only one difference.

Yep, and the reason
for that difference

Is very familiar
to the Mythbusters.

Cable broke.

And inside
nmt's high-tech classroom...

Hey, Van.
Welcome back.

Van Romero has the solution.

Flying the boat down a track
is a little tricky.

Getting a boat to go 100,
150 miles an hour...

What's gonna happen
with a fast acceleration

Is it's probably
gonna fly apart.

But we do have another option.

Instead of moving
the boat down the track,

Let's look at moving
the piling down the track.

Awesome.

If we do that,

We can accelerate this pipe
as fast as we want.

We won't have any problems.

The physics is identical

As long as we get
the closing speed

To match
the closing speed that we want.

The roles will be reversed,

And the pylon will hit the boat

Traveling at the top speed
of a speedboat.

So, it's time
to trek back to the track

And prepare the sled.

The first thing you'll probably
notice about the pole

Is unlike
our previous experiment,

It's metal instead of wood.

The reason for this is that at
the speeds we're talking about,

Wood would simply shatter,

Where we know
the metal's not gonna shatter.

The more important thing

Is the sheer amount

Of kinetic energy
it's gonna generate.

The pole plus the sled
weighs almost 600 pounds.

It's gonna be traveling
at nearly 200 miles per hour.

See, the key to any good
rocket-sled experiment...

Lubrication.

That's the kind
of kinetic energy we need

To give this boat split
a fighting chance.

But first, the marker
needs a maritime makeover.

So, we're out here
in the middle of new mexico.

There's not a lot
of ocean around, so...

We decided to make it
more marine-like.

So, we brought a seagull.

Is that the most irritating
thing you've ever heard?

With the pole sitting pretty...

Aww.

It's the boat's turn
to get nautical.

Ocean spray.

We're going to add
a little water to this boat

Just to keep the fans happy.

They really like "bifurcated
boat" to be on water.

With the mythity split 3
in commission,

They hoist the sails.

So, it's floating on air.

Well, there's something
you don't see every day.

The boat's in place.

Now it's time to load up
the sled with rockets

And see if we can
split this boat in half.

Three, two, one!

Devious Adam
moved the goal posts...

Wow, that was quick.

And created
art with explosives.

That's beautiful!

But now it's the Hyneman's
turn to paint and detonate.

You need that.

I do.
It's time to load it up.

The myth requires
100% wall coverage,

So Jamie's reducing his boom.

On our first test, we used c-4,

Which is a very fast,
high explosive.

This time, we've slowed it down

To about 1/4 or 1/5 of that
speed with ditching dynamite.

This stuff goes off
at about 5,000 feet per second,

And I'm hoping that it'll have
a lot more push with it.

Maybe it'll push some paint.

But will it impress Adam?

No fricking way.

What... how... this looks like
it weighs 6,000 pounds.

Oh, it's only 3,500 or so.

Oh, my god.

How... how does this work?

Well you put the top on,
and you bolt it down.

You pour paint in, it fills up,
the dynamite goes off,

And it shoots paint
out through the jets.

If it's okay with you,

I'd like to watch this one
from the bunker.

Yeah.

This is... you know,
this is a dangerous thing.

It is a beautiful thing.

Nice work.

And with the dynamite
in position,

Jamie's planning
to paint the town red.

Who knows what the right
paint thickness will be

For this particular
spray-paint job.

I mean, normally,

You thin paint a little bit
when you put it in a sprayer,

So I figure
this wouldn't be any different.

And in any case,
the thinner the paint,

The more it's gonna break apart
when it's sprayed.

And why not hedge my bet?

Well,
with the paint payload on board,

The sphere is locked and loaded.

Congratulations.

After all these years,
you finally made the death star.

Well, let's get out of here

Before it is actually
the death star.

The circle is now complete.

So it's time to return to base
and use the force.

But can it paint an entire room?

Okay.

Painting with explosives,
the paint ball,

In three, two, one, go.

What happened?

Let's go check it out.
All right.

Wow.

That, uh, wasn't exactly
what I had in mind.

But, um...

You've made a four-wall
rorschach test.

Jamie, what do you see

When you look at this blot?

I see valentine's day.

Valentine's day?
Well, that's not the...

Wow.
That's quite romantic of you.

Who knew?

The death ball sprayed
a red mist over the walls,

But it looks less solid color
and more hollywood horror.

All that work,
and this is what we get.

Well,
it's food for thought, isn't it?

And even though he didn't coat
all of the walls,

Jamie's not disappointed.

Well, I'm tickled pink

That my ball actually withstood
the high explosive.

That was the main thing
that I was worried about.

And the paint actually
came out the jets quite nicely.

They did
what they were supposed to.

They directed the paint
at the walls,

And you can even see
that the jets were starting

To shape the spray
the way that I wanted to

So that it didn't end up
all right in the middle.

But as far as painting
a house with explosives...

It needs a little work.

Final analysis,

Painting with explosives...
what do you think?

Well,
we made some fine art today,

But as far as painting houses,
it's just not practical.

No, it's not gonna replace
house painters anytime soon.

Got to be busted.
Let's go home.

It would actually
be kind of nice

To be able to paint your house
in a millisecond, wouldn't it?

After the break...

After seven years
of waiting to find out

If we could
actually bifurcate a boat,

We're ready to go.

Meanwhile,

At a gallery
somewhere in san francisco...

what are
my bomb paintings about?

Well, I mean,
they're really about

The universal themes of art,

The explosive moment
of inspiration,

The randomness of our creation,

The marks of detritus
we leave on others' lives.

But mostly it's just 'cause
I like to blow up.

Yeah.

Deep in new mexico,
things are about to get fast.

So, I heard
you got some rockets for us.

This is the most
dangerous part of our day...

Loading the rockets
onto the sled.

It's dangerous all right.

In fact, it's so dangerous,
it requires a costume change.

This is an incredibly tense
moment,

And the reason is
that the rockets

Have their igniters
pre-installed.

So, just by handling them,
they could ignite,

And that would be a very,
very bad thing.

And the other thing
that makes it difficult

Is that the ignition level
is not very high,

One volt at one amp.

When you just walk around
in wool clothing,

You could generate
a static charge

Of upwards of 40,000 volts.

So, that's why we have to remove

Anything that's not cotton
and ground ourselves

Because we don't want
these things going off.

Yep, they're staying grounded

'cause
the power of these rockets

Could knock
more than their socks off.

To send this pylon down
the track at 200 miles an hour,

We are using vintage,
korean-war,

High-velocity aircraft motors.

That's gonna give us
the 200 miles an hour we need,

375 G's,
and 12,000 pounds of thrust.

It's gonna annihilate
the mythity split 3.

Indeed.

That pylon will be traveling

At the maximum speed
a super-fast speedboat can go,

Which means
there's no margin for error.

To the bunker.

Okay. So, our high-speed cameras
are in place.

We are ready to go.

This is the moment of truth.

What do I think is gonna happen?

Look, that's a fiberglass boat.

It's a steel pole coming at it.

That thing is gonna shatter
into a million pieces.

Mark my words.

Well, where the curse of the
bifurcated boat is involved,

Nothing is certain.

But they've cleared the decks.

All right,
the pylon is loaded and hot.

We've got our boat in place.

Batten down the hatches.

This is it, man.

Finally, hopefully,
we can cut this boat in half.

And now it's full steam ahead.

All right.
Rocket-sled pylon versus boat.

Three, two, one.

Yeah!

Wow!
We got bifurcation!

It cut right down the middle!

We did it finally!

Ha-ha!
Awesome!

That was awesome.

Yep, it seems
the curse has lifted,

And they finally split the boat.

Finally! After all this time,
we bifurcated a boat.

But you know
what that shows me?

That dude had to be going fast.

Real fast.
Yep.

Let's go check out the carnage.

All right.

Outside, it's clear
that this ship is wrecked.

I cannot tell you
how happy I am

That this boat
is finally split.

It split in two.

I mean, it's annihilated,
but there is a clear division.

The rocket sled
does not disappoint.

It does not.

Reaching 200 miles per hour
in only 200 feet,

The rocket-powered pylon
plowed into the prow,

Tossing the boat into the air

And leaving
two halves in its wake.

All right, so, my prediction

Was that when
the channel marker hit the boat,

It would shatter
into a million pieces.

But as you can see here,
it actually tore a hole

Almost
all the way down the hull,

Leaving this in two
pretty-much-intact halves.

I've never been happier
to say that I was wrong.

And it just goes to show

That even a blunt object
like our channel marker

Could turn into a knife
when you add enough speed.

There's no way that guy
was going 25 miles an hour.

We tried it over and over at 25.

We tried it off water, on water.

It took 200
before it started to split it.

We didn't even get a dent at 25.

I think
he might have been lying.

Seven years in the making,

Four channel markers, three
boats, a barge, and a crane,

But nothing could bifurcate
the boat

Until now...
With a rocket-powered sled.

But it looks like
this one's still busted.

Well, that was fun.

What do you think we could
put on the rocket sled next?

I don't know.

Maybe a bus.
Ooh.
