The stuff we do is dangerous.

Don't try this at home.

We're
what you call experts.

On this episode of
"Mythbusters"...

...Adam and Jamie
go full throttle...

...For the most dangerous stunt
in "Mythbusters" history...

Did such an aggressive wheelie,
his head fell off.

...Testing the viral video

That a motorcycle could
surf the surface of a lake.

I want to try it.

But will it be man over bike?

Could he
plant himself right here

And just start flying?

Or will Jamie torque on water?

Meanwhile, kari, tory, and grant

Get the drop on
a free-fall free-for-all...

Oh!

I don't even want to know
what the g's are on that.

...Finding out if a criminal

Could make a parachute

Out of the paraphernalia
inside a hotel room.

What is that,
the new fall fashion?

Ah!

But will their crazy canopies...

Gonna be
a lot of wet floors

With all these shower curtains
missing.

...Let buster
skydive and survive?

Come on.

Open!

Oh!

Who are the Mythbusters?

Adam savage...

This is science in action.

...And Jamie hyneman.

Buh-bye.

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

Together with grant imahara...

That is crazy.

...Kari byron...

Aw!

...And tory belleci.

It's about to get real.

They don't just tell
the myths.

They put them to the test.

Jamie, you remember when

Kari, grant, and tory
did the episode about

A sports car
skipping across the lake?

I do.

50 miles an hour.

That car didn't skip!

It flipped!

We got one similar to that
this time,

Except this time,

It's a motorcycle
riding on the water.

A motorcycle actually
riding on top of water.

Apparently.

We got a motorcyclist,

He's riding down the freeway
way too fast,

He comes to a bend,

And when he comes to the bend,
he can't make it.

So he plows right through it,
and there is a lake,

Except that
he stays on top of the lake

And makes it
safely to the other side.

Sounds dangerous and fun.

I'm in.
Excellent.

I can't stop it.

Motorbikes and water

Seem like
a catastrophic combination.

Yet, according to this myth,

If you take the lake
at freeway speeds,

You could burn aqua
all the way to the other side.

But will
this physics-defying feat

Prove more sink than skim?

Clearly,
this episode ends with

One of us--
I'm guessing it's you --

Riding a big, powerful
motorcycle

And attempting to
keep it on top of the water.

Yeah, but I don't think

We should just
jump right into this,

Because it involves
high speed, crashes,

Drowning, broken bones.

It's risky.

All right, well,
they do make

Some very powerful
r.C. Motorcycles.

What say we take one of those
out into the field,

Ride them
over a small body of water,

And see what we can learn
on the high-speed camera.

Sure, why not.

Now, we're not gonna be going
stampeding towards full scale

Right away in this story.

We've come to a, basically,
off-road motorcycle park

Not far the "Mythbusters" shop,
and we're gonna be doing

A little bit of experimenting
with these.

These are the little
radio-controlled motorcycles,

And they happen to have
a gyroscope in the rear wheel

To help them stabilize
as they go.

The top speed on them
is about 20 miles an hour.

What that'll do in water,
I have no idea,

But that's what
we're here to find out.

Well, our scale bikes
require a scale pool,

And that's just what this is.

With a nice, gentle transition
over there,

It's only
a couple of inches deep,

And with the aid of
our high-speed camera,

Hopefully, it will illuminate
some key things we need to know

About whether or not bikes
can stay on top of the water.

And with the h20 ready to go,

It's time for
the wheels to meet the water.

Here we go.

Oh!

Oh!

Nice!

Mr. Hyneman delivers.

No riding a bike through water.

He wheelies through water.

It's not quite the "wheel" deal,

As this myth is about
skimming on two wheels, not one.

But luckily,
they don't have long to wait.

Yeah, this is it.

Whoo!

As the hyneman
masters the two-wheel maneuver.

Yeah!

Whoo!

And four triumphant trips later,

It's time to see if
the bike's riding

The top of the pond
or the bottom,

Thanks to the high-speed review.

Let us
see what we can learn.

Wow.

Sort of on the surface
right in the beginning

'cause it's coming off of
that initial ramp.

The rear wheel is down,
though.

And it's
going down further.

At this point, it's clear that
both wheels are down.

It is definitely
deep in the water.

It's almost deep enough
where I can say

It really feels like
it's riding on the bottom.

It's not
the news they were looking for.

On each and every run,
their bike is

Driving through the water
and not over it.

And that means,
for this myth to stay afloat,

Adam and Jamie are
going to need a plan "b."

Next, kari, tory, and grant
shoot the breeze.

All right, so,
this next one

Sounds like
a hollywood action movie,

But apparently,
it's totally legit.

All right,
let's hear it.

All right, so, wanted criminal,
surrounded by police,

Tracked down to
the 20th floor of a hotel.

After
a protracted negotiation,

They break down the door,
and guess what they find?

Money, jewels.

Yes.

But also
a homemade parachute.

That one sounds familiar.

The guy was stuck in
his hotel room for three hours,

And he started
making a homemade parachute

Out of
sheets and shower curtains,

But he never made the jump

Because the police broke in and
caught him before he could.

So, he never jumped.

We don't know if
the parachute actually works.

Exactly.

Can you make
a homemade parachute

Out of things you can find
in a standard hotel room.

Cool.

Yep,
this audacious escape escapade

Comes straight from
the criminal mind.

Supposedly, this bad guy

Was going to wing it
with a makeshift chute.

But could he have

Defeated gravity
for this getaway?

Is there any way
an improvised parachute

Could let you down safely?

All right, guys,
how about this?

We get all of

The standard contents
from a hotel room.

You know, drapes, sheets,
shower curtains, lamp cords.

And then we have three hours
to build a parachute.

Oh, that's great.

We can connect
each of our chutes to buster

And drop him from 20 stories,
just like in the myth.

All right, well,
we better get crackin'.

The police
are on their way.

Where's he going?

Yep. First, it's
a build-off, or "chute-out."

We're working on the myth that
you can make a parachute

Out of common things
you might find in a hotel room.

Now, that gives us
so much material.

We've got
the bedding on the beds,

The curtains,
the blackout curtains,

The rods, the strings,

Any cords you can find from
lamps or tvs or ethernet cables,

And the wealth
that is the bathroom.

I mean, we have
shower curtains, towels --

Anything you can think of.

Now, we have
three hours to do this,

Because the burglar
only had three hours,

To see which of us
can come up with

The most successful parachute.

And the clock starts now.

So, the first decision is to
choose their weaving of choice.

So, what I'm gonna use is
this blackout curtain.

It's fabric coated by plastic.

That's gonna
give me a lot of wind resistance

And not only that --
that plastic coating

Is gonna give me more strength.

Hopefully, this'll work.

I'm starting out with
the lightest,

Least-porous materials
that I could find,

Which are the shower curtains,
the liners.

I'm going to attach them

And make them
the base of my parachute.

I figure they'll
hold the air the best.

What I'm doing is

Using these curtain rods
to make a frame.

And, then, from that, I'm gonna
drape this duvet cover over it.

The reason I chose a duvet cover
as opposed to regular sheets is

I didn't want to sew any seams.

I think
if I have any seams on there,

It's going to be not as strong.

Indeed,
because strength is vital,

Considering what their
improvised chutes have to mimic.

Now, the way a parachute works

Is by increasing the
surface area of a falling object

So that way,
it has more contact with air.

And it's this air resistance

That decelerates
the terminal velocity of a human

From 120 miles an hour
to less than 5 miles per hour

For a soft landing.

So that's
what we're trying to match.

Yep,
it's a head-to-head challenge

That's going to require
some clever crafting.

Whoa.

What hotel
are you staying in?

The ritz?
I don't know.

This looks more like
the kind of hotel

Where you could
rent the hot tub by the hour.

And each mythbuster
is opting for

A different shape of canopy.

It's quite a challenge,

Especially with
shower curtains and sheets.

Grant's going for
144 square feet of fabric.

I already ripped it.

That's not a good thing.

While kari is
sewing sheets into

A more traditional dome design.

I'm using the cord from
the curtains to tie it together,

And then I'm leaving
a hole right in the middle

So that it should
sail down straight.

If that doesn't work, I'm gonna

Tie a pillow to my head
like a helmet.

And tory is

Patching together
a rectangular chute.

So, we're already
one hour into this challenge,

And I'm looking at
the size of my parachute.

I don't think
this is gonna be good enough.

I don't think
I'm gonna get this done.

It's my harness.

What is that,
the new fall fashion?

Okay, time pressure
is starting to get to me

Because I just don't think
I can get this done.

I don't think I can
get this done in three hours.

With less than
five minutes to go,

The guys race to
stitch up this challenge.

So, what I've done is
I've ripped out

All the electrical wiring
in my hotel room.

Saw macgyver do this once.

And I'm gonna use that as
my stringers for my parachute.

I am feeling
pretty darn confident.

And with
some last-minute adjustments...

If this is
knotting on the ground,

What's it gonna do in the air?

Oh, man!

I got 60 seconds.

...The cutting,
taping, sewing, and sweating

Comes to an end.

And...

Done!

Done.

Done.

Three hours, three Mythbusters,

And three hotel rooms
full of fabric later,

And they've got three parachutes
ready for the drop zone.

You might think
it looks a little flimsy,

But, hey,
it's only got to work once.

Is this gonna save
buster's life? I don't know.

But if I had to
jump off a building

And I had a choice between
no parachute and this parachute,

I guarantee you,
I'll take this choice.

Wow, kari, that's a
nice-looking parachute you made.

It actually
looks like a parachute.

Yeah, it's an artistic rendition
of a parachute.

Let's see if it
actually flies like one.

All right.
Are you ready?

Let's do it.
All right.

Later, buster goes down...

- Whoa!
- Hey!

Look at him!
Hey!

...And the tension ramps up.

Let's launch the beast.
It's now or never.

But can a motorcycle
ever turn motorboat?

It's a myth that's
hell on two wheels,

But could a motorbike
ever turn motorboat?

Well, so far,
you can lead a bike to water,

But you can't make it skim.

However, all is not lost.

Well, I, for one,
learned a lot from that test.

Yeah, who knew that
you could wheelie across water

And that your head
would fall off?

Look,
I want to somehow see

If a motorcycle wheel
at speed

Gains real buoyancy
on the water's surface,

But how are we gonna
get one of these

Going 60 or 70 miles an hour
on water

Under
controlled conditions?

Well, riding on water
says "boat" to me,

So why don't we hang a wheel
off the side of a boat?

They make boats that
go 70 or 80 miles an hour?

You bet they do.

With top speeds of
over 90 miles per hour,

Powerboats sure can
pace across a pond.

But before they
feel the need for speed,

First they need to rustle up
the wheel in the water.

What you got?

Well, at its most basic,
this is the boat.

This is the motorcycle wheel
in scale to that boat.

Obviously, it can
sit in the water like this,

And when we
get up to speed,

If the wheel does get buoyancy,
it would rise up.

And then the question is,
how much weight can it support?

And that's
where this comes in.

We can put on barbell weights
of various sizes

Until we
determine how much weight.

Sure.

I think this is
pretty straightforward.

It may be
straightforward for Adam,

But for the rest of us,
here's a graphic.

The weight of a motorbike
means that in water, it'll sink.

But if its wheels were
spinning at highway speeds,

Could that keep it afloat?

To find out, the plan is to

Attach a motorbike wheel
to a speedboat.

Then, as the boat accelerates,

The wheel should
spin up onto the surface.

But will it stay above water

If the weight of a rider
is added to it?

It's a dastardly design,

But in the workshop,

Adam's
galloping through the build.

I don't know, for some reason,

It reminds me of
a horse rearing up.

a horse made of steel.

And before
you can say "chrome pony,"

His steel-rim rig
is ready to saddle up.

And at a local lake,
it's time to put it to the test.

The open air, the sun --

There's just nothing not to love
about boating.

Honestly.

Let's get this thing
in the water.

Okay.

This here
is our test platform --

20 feet long with
a 300 horsepower outboard engine

And a tunnel-hull design.

She is built for racing,
built for speed

And will go between
85 and 90 miles per hour --

Perfect for
our testing purposes.

First up, we need to
get our rig bolted to it.

The plan here is simple --

Bolt the wheel to the boat...

I claim this scientific rig
in the name of "Mythbusters."

...Lower the boat
into the water...

Perfect.

...And then take it for a spin.

Let's
get this party started.

All right.

Are you ready?
Ready.

Go!

But almost immediately,

It's clear that
there's a problem.

The tail end is so heavy that

The boat's not only
taking on water...

You're spilling water
over the side there.

...Its top speed has plummeted.

Our problem is,
there's so much drag,

The boat's not able to
get up on a plane,

Where it
sits on top of the water.

That's
where the real speed happens.

Jamie's gonna
crawl up to the bow,

I'm gonna rig the wheel up,

And we'll see if it works.

So, with Jamie

Clinging on
as a counterbalance...

I've actually done this before
to hang on top of a car.

...It's the moment of truth.

Okay.

All right, here we go.

Come on! Come on!
Come on!

Come on! Come on!
Come on!

At first,
it all hangs in the balance,

But when Adam
gives the wheel a heave,

They finally pick up speed.

There he goes.

Yes!

As the boat clocks 50...

Yes! Yeah!

...Then 60 miles per hour...

Totally works!

...It's clear that
the wheel is riding the water,

Which is great for the myth.

What's less great is that

This crazy contraption
is so dangerous...

Yeah!

Whoa, whoa, whoa.

Wait up.

It's scary.

...That the guys decide to
quit while they're ahead.

Ooh.

Whoo!

All right, I've got
some good new and some bad news.

I am going to
start with the bad.

The bad news is is that

Our rig didn't quite
work as planned.

We had really wanted to
start to add weight

And experiment with
different speeds of the boat

To come up with a graph

Of speed-to-weight ratio
that would tell us

Exactly how fast
we'd have to hit the water at

For the motorcycle wheel
to support its rider.

And we didn't quite get that.

The good news is

Is that even though
it took everything we had,

We were able to
get the boat up on a plane

And the wheel
skipping across the water,

Which means that
there is something to this,

And it means we can proceed
with some confidence

To full scale
that this might just work.

Cornered by the cops,
could you improvise a parachute,

Defeat the free fall,
and flee to freedom?

To find out,

Kari, tory, and grant
have unraveled the rip cord

And now have three
makeshift chutes to deploy.

It's time to find out

If any of our
do-it-yourself hotel parachutes

Can decelerate buster
gently to the ground.

We've come out to treasure
island on a beautiful day

With a crane that could lift him
20 stories into the air.

We're going to drop him
with each of our designs,

But first, the control --
no parachute.

Now, to find out
exactly what buster

Is going to be experiencing
in this drop,

We're gonna attach
an accelerometer.

Now,
for him to survive this fall,

He has to withstand
less than 100 g's.

For him to
survive the fall without injury,

He has to withstand
less than 10 g's.

Don't look so sad, buddy.

Yep, once again,

Buster will have to
do what he does best

And take the fall from 200 feet.

All right, here we go.

Bye-bye, buster,
in three, two, one...

Ohh.

Oh!

God,
I don't even want to know

What the g's are on that.

Well,
thanks to the accelerometer...

All right,
let's see what we got.

...It's easy enough to find out.

Wow, look at that --
500 g's.

And he hit the ground
at 83 miles an hour.

He definitely
did not survive that.

But will jumping from 20 stories

With a homemade chute
be any better?

Oh!

Here's why we're hoping
our parachutes will work --

Gravity acts on all objects,
no matter how much they weigh,

Causing them to
fall at the same rate.

Go, go, go!

Yeah!

The only reason why
two objects

Won't fall at the same rate

Is because of air resistance.

These two pieces of paper,
in fact,

Do weigh the same amount.

But this one
has a lot more surface area.

It has to push a lot more
air molecules out of the way

To fall down, and thus...

In order for
this myth to be confirmed,

This is what our parachutes
will have to do.

You ready?

I'm ready.

And first to attempt that

Is tory's
blackout-curtain canopy.

That's something
you don't see every day.

Blackout-curtain
parachute drop,

In three, two, one...

Whoo!
Oh!

Yeah!

Amazingly, tory's chute deployed
and slowed buster down,

But unfortunately, not enough
to head off the impact.

Oh, buster
lost his head.

Oh, no.
And his hand.

Oh, that is a bad sign.

So, we just dropped
the blackout-curtain parachute.

And there's some good news,

But there's
some really bad news.

The good news is,
the parachute opened

And it
decelerated buster's descent.

However, the bad news --

When he hit the ground,
he hit it with 160 g's.

That's well over 100 g's.

Therefore, buster is dead.

That
brings the curtain down on tory.

But grant's frame-up
is still to go.

Aah!

Hey-oh!
Whoa!

Oh!
Ah!

We got
a technical difficulty.

Oh, boy.

Trouble in "mythbuster" land.

The wind has picked up,
and apparently,

Grant's rig does not like that.

Had to be a windy day,
didn't it?

Grant and his frame
are all bent out of shape.

But can the parachute
still bring buster down safely?

Look! It's batman!

you guys.

He's gonna be "flat-man"
in a second.

Oh, man.

Oh, boy.

here we go.

This is
canopy parachute,

In three, two, one...

Hey! Hey!
Look at it!

Hey!
That kind of worked!

Whoo-hoo!

Yep, as it turns out,

That was an impact of 144 g's --

A quarter of the control,
but still a lethal landing.

He hit the ground
at 29 miles an hour.

That is well above
our benchmark of 100 g's,

Which is survivable.

So, buster died
with that parachute.

And for buster's final flight,

It's time to put
kari's six sheets to the wind.

Look, I like my design,
but honestly,

I wish I had
thought of kari's design.

I mean, look at it --
it looks like

A real modern day parachute.

Come on, criminal!

It's got
a huge amount of surface area,

And it's got a vent at the top
to direct the air through,

So it's gonna have
great stability.

I think this one has

A really good chance of
saving buster.

This is curtain parachute,

In three, two, one...

There you go!

Oh!

Aw!

You had
a little deployment issue.

Late deployment!

Kari's late-deploying chute
did decelerate buster,

But he still hit the ground
at 160 g's --

Well above the lethal limit.

Okay, this is not
looking good for the myth.

I mean, we looked at the data
for all the drops.

There is not
one survivable fall.

We have to
start from scratch.

Well, maybe
we try different fabrics,

Pick out the best parts
of each of our designs.

All right, well,
let's go back to the shop

And see if we can
figure out how to

Make a parachute
that actually works.

Youtube says "yes."

The Mythbusters say "maybe."

Yeah!

Whoo!

But can a motorbike really
skate the surface of a lake?

I think I might...
Have beat Jamie.

Maybe not.

Well, it's time for this myth

To surf up or ship out.

Ever since we first started
talking about doing this story,

We knew, of course,
we'd finish on a lake.

And we had a very specific
list of attributes

We considered critical
for this lake to have

In order for us to
have any chance of success.

Number one, the lake
needed to be smooth and calm.

Two, we needed
the land-to-water transition

To be incredibly gentle,

And, three,
we needed that transition

Between land and water
to be not too muddy.

And amazingly,
we found everything we need

In this lake
in ione, california,

And in a few minutes,
what looks like a lake

May end up, in fact,
being a motocross course.

But before Jamie
"trips the lake fantastic,"

They first need a rider
with some serious grunt

And some serious
stunt expertise.

Meet eric mccrummen.

What do you think, eric?
Are you up for it?

Sure.

Eric is the designated driver,

But there's
one last thing to clarify.

I am currently standing in

The path our motorcyclist

Is going to take
across the water,

And it is
38 inches deep in the middle.

If that motorcycle
makes it across,

It rode on the water.

That's official.

Yep, it'll be official,

But only if it works,

Which means it's time for

The rubber
to meet the reservoir.

Well, he's all set.

He's 375 feet away.

You want to wave him in?

Let's launch the beast.

It's now or never.

Okay.

Here he comes.

Whoa!

that worked!

He totally
stayed on top of the water.

That was beautiful.

He, like, parted it,
like a little red sea.

That was amazing!

Amazing is right.

Remember,
the lake is over 3 feet deep.

Yet, instead of sinking,

Eric sailed 50 feet
at 60 miles per hour.

But now
Adam and Jamie want more.

Do you feel like
you could go a little longer?

I think so.

Excellent!

I have to say, I'm pretty
pleased about this so far.

Eric successfully just
crossed 50 feet of open water,

Not fake water
with land underneath --

Deep, open water --
50 feet on a motorcycle.

So, now we're gonna
cross 100 feet.

He's gonna go for
a 100-foot length of water,

And we're just gonna
see how far we can get.

Yep, they're
doubling down on the dirt bike.

But will eric make it
to the other side this time?

I'm excited --
100 feet.

It's time to put our money
where our mouth is.

Let's do it!

The pressure is on
as eric revs the bike...

...Gets it
up to 60 miles per hour...

...And...

Wow! Yeah!

...Leaves the lake in his wake.

He was
on top of the water.

He was totally!
I mean, he was actually --

I saw him do this
on top of the water.

That was beautiful!

It's clear
from what we're seeing --

When this bike
goes across the water,

It's riding on the water.

Because we can see
the wheel is bouncing.

It's just like it was

When we were on the speedboat
doing our bench test.

That means that
it's hitting the water

And rebounding off of it.

It means that
we're riding on water.

And that means this myth
is well and truly confirmed.

But it's not
the end of the road yet.

Dude,
I believe we have proven

That you can ride a motorcycle
across the water.

I think we have.

But, you know,
I have a question.

What's that?

Is what is happening there

Actually
due to his momentum,

Like skipping a stone
across the water,

Or is a bike this powerful
capable of actually

Going out like a watercraft

And continuing to power its way
across the top of water?

That is
a good question.

I want to try it.

Okay.

Pulling the cords on
peculiar parachutes is not new.

But could you source
a successful chute

From your hotel room?

After
a free-fall free-for-all...

...Maybe not.

Buster did not
survive any of these drops.

So now they want to know if
anything in a hotel room

Could let you down safely.

Since our
do-it-yourself parachutes

Didn't quite
give us the results we wanted,

We've come back to the shop

To do some
small-scale experiments.

We're gonna test every fabric
you might find in a hotel room.

I'm gonna make small parachutes,

Put them on top of
a big, industrial fan,

Blow it upwards,

And see which parachute is

Actually going to
yield the best results.

Now, our benchmark for this test
will be real parachute material.

In the end,
what we're looking for

Is the material
that best matches

A parachute's loft and weight.

Oh, yeah, and something that can
also be found in a hotel room.

Now, instead of having
our parachute falling down,

We're gonna have it stationary

And have the fan
blow air up into the chute,

Acting as if
the parachuter were falling.

And then we're gonna find out

Which material
has the best wind resistance

So we can see which material
makes the best parachute.

Yep, it's all about the fabric

With the most air resistance,
or loft.

So, with a force meter attached,

They fire up the fan
for the control --

The real parachute.

Hey!

All right,
it looks good and stable.

1.79 for the control.

So, that's
our ideal performance.

1.79 is the lift to beat,

And the first makeshift chute
is the shower curtain.

We're at 1.86.

This has better wind resistance
than the parachute material.

Then they try
the blackout curtain.

2.0.
2 pounds?!

That is our best performer
so far.

And finally,
the remaining swatches.

Okay, we've settled at 1.37
for the polyester drape.

All right, 1.67
for the cotton sheet.

Next.

Okay, looks like
we got 1.65.

Canvas curtain
pretty good as a parachute.

That's five pocket parachutes

And five
impressive lift results.

But that's not
all they're looking for.

We have a winner --
the blackout curtain.

It was the most air-resistant,

And gave us
2 pounds of pulling force.

However, the problem here is
it's heavy.

So, what I need to do is

Weigh each of these
parachute materials

And see
which one is the lightest

And has similar air resistance
to our parachute material.

So it turns out,
the winner is -- shower curtain.

This is what we're gonna

Build our final parachute
out of.

So, while the blackout curtain

Had the most air resistance,

The shower curtain was lighter.

And that, coupled with its lift,

Makes it the best material
for full scale.

So, we've chosen
the shower curtain

As our final material
for our parachute.

And now that means
we have to scale up.

Here's how it goes.

Gravity over rho.

9.8 meters per second squared.

Diameter is
2 times the square root of...

A diameter equivalent to
17.4 feet.

Now, you could never get that
much shower curtain

Out of one room.

But if you had a whole floor?

Now you're talking.

With a diameter of 17.4 feet,

Their shower-curtain chute
is gonna be giant.

So they've opted for
the classic dome design.

But making a hemisphere
out of square curtains

Means they need a plan.

This is
a little pattern model of

What our finished parachute
should actually look like.

We're actually going to
take each of these pieces

And make a large pattern
out of paper

And then construct each one
out of shower curtain.

Now, it's hard to
actually figure the scale

Till you really
see the pattern laid out.

This is going to be
a huge parachute.

It's a mammoth task of

Attaching 24 curtains
with duct tape...

If this duct tape doesn't hold,
buster's doomed.

...And then
cutting out the six panels.

Now we stitch them
all together, right?

Oh, yeah.

All right.

Now, after actually

Making our pattern,
cutting it all out,

I think our original parachutes
were a lot more labor-intensive

And took a lot longer
to put together.

Is that all...
The pieces?

Yeah, that's it.
That's the pieces.

That's it
for the main chute.

Now to
bring in the reinforcements.

Our next job is to
reinforce this hole at the top,

Which is actually gonna
bear a large amount of the load.

With a little curtain cord
taking up the slack,

The last element is the lines.

almost done.

This is it --
the last two lines.

And with that,

It looks like this canopy caper
is all stitched-up.

That might work.

Shower curtains
and duct tape --

Who would have thought?

Next stop --
30 stories high.

Cool.

Please don't try
anything you see us do at home.

This is dangerous work,
and we're professionals.

So far
in this parachute escapade,

For buster, it's been
more high dive than skydive.

But will that change with their

Best-case scenario
shower-curtain chute?

Dude,
this is super cool.

We're at
the mare island shipyard,

Where we've been given access to
a 50-ton crane.

Now, this is gonna
give us the ability to

Raise our parachute and buster
30 stories into the air.

We're going to drop him
into this dry dock

With all his accelerometers
and find out

If this is going to be
an effective parachute.

That's an extra 10 stories

To decelerate
their shower-chute.

Chin up, buddy.

So first, they need a frame
of reference at this height,

With the most successful chute
from their previous test.

All right,
go ahead and take it up.

Just like
its drop from 20 stories,

The frame
buckles under buster's weight.

The good news is,
it's doing

Exactly what it did
last time.

But now it has
more time to decelerate.

Okay, this is
hotel parachute with the frame,

In three, two, one...

Yeah.
Whoo!

Hey!

Oh. Oh!
Wow!

Dang,
he hit the ground hard.

Well, let's check the data
and see if he survived the fall.

Look, I'm not a doctor,
but that does not look right.

Yep, and closer examination

Proves that
even from 30 stories,

Buster still clocked
over 140 g's on his landing.

Clearly, a 1-room parachute
is a flop,

But can a 24-room
shower-curtain canopy

Do any better.

There's gonna be
a lot of wet floors

With all these shower curtains
missing.

I think they're gonna
bill it back to our room.

This is it --
the final experiment

To see if you could take
materials from your hotel room,

Make a parachute,
jump out, and survive.

Now, we've taken

Everything we've learned
from our small scale.

We're gonna use
our shower curtain.

We've made
a dome-shaped parachute,

We put a hole in the top,
and we have a drag chute.

This time, we're gonna be
dropping from 30 stories

To see if
buster will actually survive.

This is gonna be so awesome.

Now, we know
from our initial experiment

That without a parachute,

Buster's impact
can get to 500 g's,

And that's from 20 stories.

The goal for today with our

Super-final experiment
shower-curtain chute

Is to get that number
down to 100 g's from 30 stories.

Bonus is if we can
get that down to 10 g's --

That's a landing
you can walk away from.

The team preps the canopy

And, for stability,
adds a drag chute.

Now, I know
what you're thinking --

"why do you guys
have a drag chute?

That's no fair."

Well, actually,
it's my laundry bag,

And I travel with it
all the time.

Then the lines are attached.

All of these are 18-feet long,

Which should give us
the minimum our lines should be

So that it opens
to the perfect circumference

And drops
at the most stable rate.

I love
your optimism.

Let's take it up.

It's crazy, but a parachute

Made out of
shower curtains and duct tape --

I think it's gonna work.

Our science is sound.
The calculations all work out.

It works on paper.

I think buster
might actually land safety.

Well, buster will have to
find that out the hard way,

Or, if kari is right,
the soft way.

Suspended from 30 stories,

It's time for this myth's
shower-curtain call.

All right, here we go.

Shower-curtain parachute,
in three, two, one...

Come on.

Open.

Open!
Oh!

Do you think
it might have worked?

Did you see
how light he landed?

Let's go check the data.
Yes!

Initially,
buster was on a crash course,

But meters from the ground,

Amazingly,
the shower curtains opened

And gently slowed his drop.

The question now is,
did he survive?

Am I -- am I seeing
what I'm seeing?

Yeah, that's the peak
right there.

4 g's?!

He survived the landing
without injury.

That's so cool.

Our parachute worked,
and the best part is,

Buster received 4.2 g's,

Which means
not only did he survive,

He survived without injury.

However, the problem here is,

He had way more shower curtains

Than the criminal
would have had,

Way more time to build it,

And the criminal didn't have

The engineering
that we used to make this.

So, even though
buster isn't busted,

This myth is.

Next, we hook this up
to the ironing board

And go kite surfing!

Come on!
Whoo!

I can't pull it.

It's too strong.

After the break,

Jamie puts his life on the line.

Here he comes.

But can he motocross over
4,000 feet of water?

Whoa!

Obviously,

If you're gonna
ride a motorcycle on water,

Weight is a huge issue,
as is power.

And that's why I've chosen
this particular motorcycle --

Because it's made by
a company in indiana

Called service power sports,

And what they do is, they take
a lightweight aluminum chassis

That normally only has
a 250cc engine on it.

Instead, they put a 500cc,
high-performance,

2-cycle motor on it,

And that makes it,
power-for-pound,

About as good as you can get
in a dirt bike.

It's a rocket.

Welcome back.

All episode long,
we have been testing a story

That a motorcycle might just
be a viable water vehicle.

Seriously.

And with a motorcycle wheel
strapped to

The outside of
a high-powered speedboat

Going 70 miles an hour,

It really seemed like

There might be
something to this story.

Yeah!

So, then we got
a professional motocross rider,

And we gave him
100 feet of open water to cross,

And he was able to do it.

Wow! Yeah!

But now mr. Hyneman
has a brand-new question --

Is the motorcycle

Skipping across the water
on its own momentum

Or does it have enough power
to continue indefinitely?

And Jamie wants to try it.

Yep, while eric
crossed a mere 100 feet,

Jamie wants more.

It's
a nice flat run.

He wants to see if the bike can
get such a grip on the water

That he can
speed across the entire lake.

To do so, he'll literally be
putting his life on the line,

But not without
some modifications.

First, the run up to the water
needs to be smoother

To let Jamie really let rip.

I think that ought to do it.

Then the bike
needs a flotation device

So it doesn't drag him
to the bottom if he fails.

I believe
I've got enough flotation here

To make it float.

Maybe.

And finally,
a lifeguard team is on standby.

This is
where it's all about to happen,

But what exactly
is going to happen

Here at the transition
between land and water?

By the time
Jamie reaches this point,

He should be going
between 55 and 75 miles per hour

When he enters the water.

Could he just skip
all the way across the water

To the opposite side
of the lake,

About 3/4 of a mile away?

Or could he plant himself
right here and just start flying

And become his own cautionary
discovery channel documentary

About what not to do?

It's one of
the most dangerous experiments

In "Mythbusters" history.

Here he comes.

At breakneck speed,
Jamie hits the water,

And then...

Whoa!

It's man over bike.

Let's go over to him.

Adam and the medic team rush in.

He's good.

But it'll take more than
a 70-mile-an-hour high dive

To hurt the hyneman.

You all right, sir?

I'm just fine.

I think
it did a little bit of a --

What is it,
a half-gainer or something

Into the water?

Definitely no broken bones
or anything.

Good.

The good news is that
Jamie's fighting fit.

The bad news is that
he traveled only 80 feet,

Far less than eric's effort.

So, what went wrong?

This is one of those cases where

If it ain't broke, don't fix it.

We added this foam, just so that

We could retrieve the bike
without drowning it afterwards,

But it turned out that the spray
coming up off of the wheel

Was providing a certain
amount of lift back here,

Which, in turn, made more stress
on the front wheel,

Which made it plunge
and made me do a somersault.

So, I'm gonna go back to
the original type of bike --

We have a second one --

And have another try.

You heard that right.

Jamie's getting
straight back on the horsepower.

And what's more,

This time,
he's upping the speed to 80.

But will that allow him to
burn aqua all the way across?

Yeah!

Yeah!

Oh!

He's good!

Beautiful!

That was amazing!

It seemed to go on forever!

Riding, riding, riding, riding.

That's, like,
easily 300 feet or more, buddy.

That was amazing.

Piece of cake.

How you feeling?

Relieved it's over
and I'm alive.

Incredibly, Jamie hit the water,

Throttled the throttle,
and surfed for over 300 feet.

And while he wasn't able to

Get a good enough grip
to carry on across,

It's still myth,
well and truly, confirmed.

In case there's any doubt,
I'm standing on the bike.

It's in
about 8 feet of water, maybe.

So I was riding on water
for about 300 feet.

So, riding a motorcycle
across the water --

Busted, plausible,
or confirmed?

Confirmed.

Not recommended,
but it's confirmed.

Yes,
but only for 300 feet.

I was
hoping for further.

I'll settle for that.

And so will we,

So why not cue the music
for a motocross water montage?

Yeah!

Yeah!

Yeah!

That was amazing!

Have you had enough?

Of course you haven't!
