CHARLIE: Hey, guys, Charlie
here. You know my sister Kirby.

KIRBY: Hey!

CHARLIE: Today we're
hanging out in State
College, Pennsylvania.

KIRBY (off-screen):
We're learning how to be
test engineers by doing

stuff like this.

CHARLIE (off-screen): And this.

KIRBY: And this.

CHARLIE (off-screen): Whoa!

KIRBY: It's time
for Weird But True!

CHARLIE: It's time
for Weird But True!

(theme music plays).

CASEY (off-screen):
And, there you go!

KIRBY: I'm never
gonna be good at this.

(oven timer ding)

CASEY: Oh, sounds like my
homemade bread is done.

I gotta go run it over
to the homeless shelter.

CASEY (off-screen): So
I'll see you guys later!

CHARLIE: See ya Case!
Hey guys!

KIRBY: And our super talented
amazing sister strikes again!

CHARLIE: What's
goin' on, Kirb?

KIRBY: I mean, I love Casey,
but sometimes her achievements

are really hard to live up to!

(playing clarinet poorly)

(playing clarinet)

CHARLIE: Wow. Whoa!

What? Casey!

What? Wow!

Oh yeah, she's pretty
much good at everything.

KIRBY: Yeah.

I mean usually I can take her
achievements in like science

and math and history
and art and music,

cause I don't even like
the clarinet anyway.

CHARLIE: Ok, so what's
bothering today?

KIRBY: Today, that all
changed, when Mr. B.,

my science teacher,
gave us our final project.

CHARLIE: This year's final
project is the egg drop!

Students must build a
homemade contraption,

to protect an egg from
a fall to the ground.

To get an A you must beat
the school record set by a

legendary builder.

My favorite student, who's the
sister of somebody sitting in

this very room.

An amazing person named Casey.

No.

KIRBY: Yes.
CHARLIE: Really?

KIRBY: 100% she's considered
the best builder in the entire

history of my school.

Building is my thing.

I own building!

KIRBY (off-screen): I've
built vegetable boxes,

a dining room table, even a
chicken coop with windows and

shingles and everything!

It's my thing!

I should have that record, but
there's no way I'm gonna beat

Casey so I might as well
drop out now, leave school,

and go move to a deserted
island in the ocean.

CHARLIE: Kirb, deep breaths.

What if I could guarantee that
you could go into class with a

record-breaking egg protector?

KIRBY: What are
you talking about?

CHARLIE: So you can
build things, no problem.

And if we could test their
performance, we could

test our way to
a record breaking idea.

All we gotta do is figure
out how scientists test
their products.

KIRBY: Hmm, I
don't know Charles.

CHARLIE: I feel good
about this one, Kirb.

There's nothing we can't do
without some paper and glue.

So that means today we're
unraveling the world of.

KIRBY (off-screen):
Test Engineers!

CHARLIE (off-screen):
Test Engineers!

KIRBY: I don't know if
I can do this, Charles.

CHARLIE: All we have to do
is approach things calmly,

from an academic standpoint.

Like we do, right Kirb?

KIRBY: Like we do.

So, what is an
engineer anyway?

CHARLIE (off-screen): An
engineer is a person with

scientific training
who designs and builds
complicated products.

You've built chicken
coops and vegetable boxes,

you're an engineer Kirb.

KIRBY: So, engineers
build chicken coops?

CHARLIE: Not exactly, there
are a whole bunch of different

types of engineers.

CHARLIE (off-screen): Let's
see, there's agricultural.

Computer. Mechanical.

Nuclear. I've got 'em all.

And these are my favorite.

Super rare, limited
edition, mint condition,

first printing rookie cards.

Check 'em out.

Willem Kolff and Robert
Jarvik, biomedical engineers.

They led the team that
invented the Jarvik-7,

the world's first artificial
heart implanted in a human.

Or how about this one,
Harold Rosen,
electrical engineer.

He's known as the father of
communication satellites.

Television, radio,
telephones, the Internet,

it all works today because
of these satellites.

And finally, look at
this one Bill Baker,

structural engineer.

Bill worked on
the Burj Khalifa,

the tallest
structure ever built.

It has 163 floors,
57 elevators,

and Bill Baker figured out
how to make it all stand up.

KIRBY: So they're builders?

CHARLIE: Like you.

KIRBY: But what do
test engineers do?

CHARLIE: Well they build
and create methods to test

products over and over and
over to make sure they're safe

and follow specifications.

KIRBY: Ok, but
here's my question.

KIRBY (off-screen): Why
are they so important?

If a product is
already developed,

why does it have to be tested?

CHARLIE: Well it's so often
that a product doesn't perform

the way it's supposed to.

Or, in some cases,
it's a total fake.

Let me show you something.

Here's some examples of
why we need test engineers.

CHARLIE (off-screen): Let's
start with this one.

Ladies and gentlemen.
We've burst the worst.

Reversed the curse. History will
know that I was the first.

Have I got a product for you,
this right here is the

cure for diabetes!

CHARLIE (off-screen): Takes
out the bad stuff and fills
you with glad stuff.

It never fails!

KIRBY: But there's
no cure for diabetes.

CHARLIE: Exactly.

See the truth is, some guy
mixed together a bunch of

plant extracts and lied
about it being a cure!

KIRBY: He was
ripping people off!

CHARLIE: Yeah, but now test
engineers test products like

this to make sure
that we're not duped.

And in other cases the
product "failures" were
completely accidental.

Ladies and gentleman.

CHARLIE (off-screen): Built to
astound, travelers abound.

Takes you clear across
the Puget Sound.

Have I got a product for you,
this right here is the

Narrows Bridge, Pride of Tacoma!

CHARLIE (off-screen): No
town or city has seen a
bridge so pretty.

It never fails!

It did fail.

It couldn't handle the wind,
which made it so wobbly that

eventually it
just broke apart.

But now, test engineers test
bridge designs in wind tunnels

to make sure they're safe.

Test engineers also test
little things that just might

need a tweak or two.

Ladies and gentlemen.

CHARLIE (off-screen): Before the
glow, you'll be in the know.

Saves the house, the
yard, the whole chateau.

Have I got a product for
you, this right here is
the smoke detector!

(beeping)

It spots the smoke and gas
before the flames amass.

It never fails!

It never failed.

But it was absurdly expensive.

Nobody could afford it.

So, by testing different
versions over decades and

decades, they were able
to create one that

everybody could afford.

See, test engineers help
in a whole bunch of ways.

KIRBY: They help us
from getting duped,

they make things safer, and
they can fine tune things to

make them even better.

CHARLIE: So we
have a game plan!

KIRBY: Wait, we do?

CHARLIE (off-screen): Yeah!

You build an egg protector,
which we can test and test and

test and test until we're
sure it can break the record.

KIRBY: But we don't
know how to test things.

CHARLIE: We don't know how
to test things yet, Kirb.

But the answer is
always out there!

And I think I know
where ours is today.

Guys, we're heading to
Penn State University.

CHARLIE (off-screen): We're
off to visit the research lab

at Penn State's College
of Engineering to learn
from the pros.

They're experts in
testing products.

KIRBY (off-screen):
Weird but true.

CHARLIE: Hey, guys!

We made it to State
College, Pennsylvania,

home of Penn State University.

Penn State!

KIRBY: We're here to
meet with Dr. Memari,

who's a professor of civil
and architecture engineering,

and the director of the
Pennsylvania Housing
Research Center.

CHARLIE (off-screen): His
favorite Weird But True fact

is, the glue like substance on
stick it notes is actually a

failed super
adhesive invention.

His research focuses on
testing materials that can

help buildings withstand
extreme weather.

KIRBY (off-screen): So if he can
help a skyscraper withstand a

hurricane, maybe he can help
me with my egg drop design.

CHARLIE: Let's go say hi.

KIRBY: Let's go.

CHARLIE: Dr. Memari,
it's nice to meet you.

DR. MEMARI: Nice
to meet you, same.

CHARLIE: Kirby's got a
big egg drop project,

and we're trying to figure out
how to test the devices that

she's creating so we can
guarantee that she can break

the school record and protect
an egg from the biggest drop.

And we heard that a
lot of what you do is
testing materials.

DR. MEMARI: We like to
break things so that
we learn from them.

So we test like a column, or
a beam, or a wall, or a glass,

or a window.

DR. MEMARI (off-screen):
We test them to failure.

We understand their capacity.

And then we throw in
the factor of safety,

so that when you put it
on the building it
doesn't actually fail.

DR. MEMARI (off-screen):
You have a buffer.

It's safe.

KIRBY: So you guys are
trying to break the stuff?

DR. MEMARI: Absolutely.

KIRBY: You're trying to see.
DR. MEMARI: Absolutely.

KIRBY: What's the
absolute heaviest.

DR. MEMARI: And we get a
kick out of that, by the way.

CHARLIE (off-screen):
Dr. Memari has us set
up our

own test, so he can
evaluate our techniques.

So this is the lab
guys, where they test
the strength of glass.

KIRBY: So let's go through
some potential scenarios where

your windows might be damaged.

CHARLIE: For example, a group
of gorillas breaks out of the

local zoo and tries to
break into your house!

CHARLIE (off-screen):
What is the result, Kirb?

KIRBY: Bananas do
not break windows.

KIRBY (off-screen):
The chimps failed.

For the next few
experiments, we're gonna
need a lab assistant.

CHARLIE: Introducing
Architectural and

Engineering PhD
candidate, Mehrzad.

Thank you for contributing
to the scientific
community today.

MEHRZAD: Thank
you for having me.

CHARLIE: Weird but true,
they use chickens to
test the strength

of airplane windshields,

which is probably something
exactly like this!

KIRBY (off-screen): Oh,
that was so gross.

CHARLIE (off-screen): Oh man.

Chickens do not break windows.

Now we know.

El Nino sweeps up a farmer's
market stand in California and

brings watermelons all
the way to your house!

Watermelon didn't
break the glass either.

KIRBY: Based on our data, I'd
say glass is indestructible.

CHARLIE: It's the only
logical explanation.

CHARLIE (off-screen): Now
Dr. Memari and his right hand

man, Paul Kremer, review
our testing protocols.

We just collected some pretty
great data that we think could

really help you guys out.

KIRBY: Charles took a
slingshot, big slingshot.

CHARLIE: Pow.

KIRBY: And he loaded it
with watermelons, bananas,

bunch of stuff.

DR. MEMARI: To do what?

KIRBY: Slung it at the glass.

CHARLIE: To see when it
would break and when it
would not break.

DR. MEMARI: Wow. Paul what do
you think of this?

PAUL: Well, it seems like
maybe there are some things

you could do if you're trying
to really be more accurate

about when the glass
is going to break.

CHARLIE: What are you saying?

Is our, do we not have an
accurate experiment here?

PAUL: We have to think about
each and every variable that
we're working with.

How is it that I'm going to be
able to control this variable

during the experiment?

DR. MEMARI: That's where
Paul's expertise comes
in the picture.

Because he has to come up with
the equipment that actually

throws the right size,
at the right speed at
the right distance.

CHARLIE: It seems much more
regimented, these tests,

than we kind of thought.

Is that right?

DR. MEMARI: Scientific Method
governs really any testing

that we do.

CHARLIE: All right guys,
the Scientific Method,

it's kind of like a
set of guidelines,

or protocol that scientists
follow every time they do
an experiment.

Let's look into that
just a bit more closely.

Welcome, to the super serious
science laboratory where we do

everything by the book.

KIRBY: By the book!

CHARLIE: We follow
the Scientific Method!

KIRBY: To a T!

CHARLIE: Today's super-secret
highly classified scientific

experiment is about:
bright blue bouncy balls.

First we make an observation.

KIRBY: These bright blue
bouncy balls do not bounce

to the same height!

CHARLIE: We ask a question.

KIRBY: Does size affect
bouncy ball bounce-ability?

CHARLIE: And form
a hypothesis.

KIRBY: I hypothesize that if a
bright blue ball is larger it

will bounce higher.

CHARLIE: And we design
an experiment to test our

hypothesis that
keeps everything.

KIRBY: Everything.

CHARLIE: Everything the
same, except the one
variable we are testing.

KIRBY (off-screen): We're
comparing two bouncy balls

that are the same
color, same brand,

made out of the same material,
dropped from the same height,

bouncing at the
exact same spot.

The only difference
is the size.

CHARLIE: We analyze
our results.

KIRBY (off-screen): We
dropped each ball 50 times,

and calculated our
average bounce height.

CHARLIE: And we
revisit our hypothesis.

KIRBY: We accept our
hypothesis and conclude that

when dropped from the same
height onto a wooden plank,

a large bright blue bouncy
ball will bounce higher than a

small bright blue bouncy ball.

CHARLIE: There you go.
KIRBY: Science.

CHARLIE: Boom.
KIRBY: It's amazing.

CHARLIE: Woohoo!
Back to the lab!

DR. MEMARI: For the more
scientific testing we use a

compressed air cannon.

CHARLIE (off-screen): In this
new trial to test the glass,

we'll keep everything constant
except the pressure from the

air cannon, which controls the
speed and direction that the

ball bearing will travel,
also known as velocity.

PAUL (off-screen): Before
we have you shoot,

we establish the
distance consistently
that you'll shoot from.

PAUL (off-screen): I'm thinking
we'll start with a low velocity,

and then have you move up at
progressively higher speeds

with the ball and, and see
what kind of damage we get.

CHARLIE: Sounds good.
PAUL: Okay.

PAUL (off-screen): So I'll
hand you the ball and let you
do the honors of shooting.

I've dialed in
to the regulator,

a pressure of 40 PSI.

Just hold the cannon level.

PAUL (off-screen):
Ok we're good.

CHARLIE (off-screen):
Three, two, one.

(shoots cannon)

Okay, we got a nice little
uh what's the name of that?

PAUL: That a Hertzian cone.

CHARLIE: A nice
little Hertzian cone.

CHARLIE (off-screen):
Cool science word.

Hertzian cone: an expanding
cone of glass that's ejected

on the opposite side of
the glass from the impact.

So it hits it and
the nub pops out.

PAUL (off-screen):
The backside, right.

CHARLIE (off-screen):
That's so cool.

PAUL (off-screen): So this next
pressure, I'll do, is 80 PSI.

CHARLIE: Three, two, one.

(shoots glass)

Ohh. There we go.

PAUL (off-screen): Right.

CHARLIE: Woo!

PAUL (off-screen): So we
see that the fracture
patterns emanate

out quite a bit from
the impact zone.

CHARLIE: So in this experiment
we were testing different

velocities of the
same size ball.

We were trying to control
everything and the only thing

that was changing
was the velocities.

CHARLIE (off-screen): Now, we're
gonna try different size balls.

So we're trying to keep the
velocity the same and testing

small to larger sizes.

And I think Kirby's gonna
give that one a shot.

KIRBY: You ready?
PAUL: Yep.

(shooting ball)

KIRBY: Yes!

PAUL: That was exciting.

PAUL (off-screen): And the
interesting thing is, this
ball went 70 feet per second.

So, much larger ball,
much lower velocity at
the same pressure.

KIRBY: Wow.

PAUL: But yet, it caused a
failure where the other

ball size couldn't.

CHARLIE: So that ball that I
shot was like the size of a

pea and the one that Kirby
shot was the size of.

KIRBY: Uh.

PAUL: Maybe a meatball.
KIRBY: Yeah, a meatball.

CHARLIE: Maybe a meatball?

Holy cow, that
wrecked the thing.

CHARLIE (off-screen): It all
comes down to control.

KIRBY: Mm-hm, and through all
these trials we got more data.

KIRBY (off-screen): We got to
figure out the breaking point,

or the success point.

And I think we can use
that for the egg drop.

CHARLIE: All right, Paul,
thanks so much for
teaching us today.

PAUL: You're welcome,
you're welcome, yes.

CHARLIE: Thanks so much
for hanging out with us.

KIRBY: Thank you so much.

CHARLIE: All right, guys,
looks like we got a lot

of work to do.

We're going to head back to
HQ and start putting together

some egg-protecting
contraptions.

KIRBY (off-screen):
Weird but true.

CHARLIE: Hey guys.

We just got back from the
testing lab at Penn State.

KIRBY: Super cool place.

CHARLIE: And now it's time
for Kirby to work her magic.

All right Kirb, I already
know you can build a

sweet egg protector.

Now all we have to do is apply
what we learned and test our

way to a record
setting design!

KIRBY: I think I might
be able to do this.

Alright.

(deep breath)

Deep breaths.

And it's time to
hit the workshop.

All right Kirb, you got this.

The idea's out there, you
just don't know it yet.

Why does the egg break?

Mr. B. mentioned
this in class once.

What was it?

CHARLIE: As the egg falls,
it has a certain amount of

kinetic energy in
the form of speed.

After it hits the
ground it has no speed.

So no kinetic energy,
but where does it go?

Well it turns into a force
that is applied to the egg

causing it to crack.

So if you think about it, if
you're able to slow down the

egg as it falls it will
have less kinetic energy and

there'll be less of a
force applied to the egg.

And it might not break.

KIRBY: I need to
slow the egg down!

And build something
like a parachute!

KIRBY (off-screen): If
we take a little cloth,

add some string, a little
holder for the egg and, boom.

CHARLIE: Test number one!

Remember guys, in order
for this to be a perfectly

accurate test, we have
to control everything.

Every time Kirby's gonna hold
out her hand and drop her egg

contraption from three
different heights.

First the top of the stairs.

Then the first layer of our
tree house and if we can make

it, the second layer
of our tree house.

Breaking Casey's record.

Every single time it's
gonna fall onto the same
service, the ground.

All right Kirb.
Give it a shot!

CHARLIE (off-screen): Ooh!

Let's see what we got.

(screams)

Casey's record has
not been broken.

KIRBY: Yet, I can try again.

What else did Mr. B. talk about?

CHARLIE: To reduce the force
on the egg you could also give

it some sort of protective
armor or skeleton.

When this breaks, it uses
up some of the energy.

So less of a force is applied
to the egg, and again,

it might not break.

KIRBY: A skeleton!
I can do that.

KIRBY (off-screen):
When it hits the ground,

these straws will break,
using up some of the energy.

CHARLIE: Test number two!

Same test, same height,
same everything.

The only difference is
the egg contraption
that we're dropping.

Let's go, Kirb.

KIRBY: Oh! It worked!

CHARLIE: Success!

KIRBY: Let's go to the
next level Charles!

Come on! Here we go!

Cross your fingers!

Ohh! Success again!

KIRBY: Yes!

We're going up Charles!

No one's done it
on the top level.

Come on, hand it up, we're
gonna beat Casey's record!

I'm so excited!

This is it. Let's go.

Egg Drop Champ!

It's happening!

CHARLIE (off-screen): Ohh!

The record has
not been broken.

KIRBY: Yet!

I'm on a role! One more time.

C'mon, Mr. B.

I know there was
one more thing.

CHARLIE: Have you ever
fallen on the sidewalk?

It hurts.

But have you ever belly
flopped onto a mattress?

It doesn't hurt as
much, that's because
it cushions you.

So if we can give
the egg a cushion,

it'll function by lengthening
the duration of the impact.

So that at any given time
there's less of a force

applied to the egg.

And again, it might not break.

KIRBY: A cushion!

Where's the foam?

It's beautiful.

I think this is the one.

I might have done it!

CHARLIE: Test number three.

CASEY: Hey guys.

KIRBY: Casey?
CHARLIE: Casey!

CASEY: Casey!

I just got back from
donating a femur.

You guys aren't doing an
egg drop back here are you?

KIRBY: No, no, no, no.

CASEY: You know, I've got the.

KIRBY: School record?

No I didn't know that.

CASEY: Hey, I've still
got my egg protector.

I can go grab it and we
can do some egg drops.

CHARLIE: Ooh, ho, ho, ho!

Buckle up and grab your
popcorn everybody because we

got a sister-sister
egg drop duel!

Don't go anywhere cause this
is the best thing to ever

happen ever.

CHARLIE (off-screen): Here it is
folks, the duel of the century.

Sister versus sister.

The school record on the line.

CHARLIE (off-screen):
Three, two, one, drop.

Casey's egg.

Ooh, did not make it.

CHARLIE (off-screen):
Kirby's egg?

An intact egg!

KIRBY: Yes!

Victory!

CHARLIE: We have a
new school record!

She beat you, Case.

CASEY: I know.
She's a good builder.

You know, I've got this bridge
that I've been working on to

try and help some baby
ducks cross the highway.

Maybe she can help me out.

CHARLIE: Yeah, for sure.

All right guys, looks
like we got a new
project on our hands.

But thanks so much
for stopping by!

Come by again when we discover
more things that are weird.

CASEY: But true.
CHARLIE: Well, see ya later!
Baby ducks?

CASEY (off-screen):
Really small.
