08x07 - Duct Tape Hour 2

[bunniefuu]

***

we consult with experts.

We take every precaution and

we have years of experience
in doing row situations.

On this episode of
"Mythbusters" --

amazing.

Strap yourselves in for
another duct tape-tacular.

***

Adam and Jamie are
stretched to the limit

and taken to the brink

as they try to cross a chasm

***

on a bridge made of duct tape.

All for the glory.

Meanwhile, Kari, Grant and
Tory are hitting the road.

What took you so long.

To find out if duct
tape can keep a car

from going to pieces.

She's a mad woman!

Then it's a race
to the finish line

***

to see if the sticky stuff

***

can stop a speeding
car in its tracks.

Who are the "Mythbusters"?

Adam savage.

***

and Jamie Hyneman.

I call it my pop g*n.

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

Joining them, Kari Byron,

***

Tory Belleci

***

and Grant Imahara.

***

they don't just tell it.

They put them to the test.

Mythbusters

oh, no.

Oh, yes.

That can only mean one thing.

Yes, it can.

It means back by popular demand,

time for the duct
tape special number 2.

It was one of our
most popular shows.

I'm giving it all
we've got, Captain.

When the "Mythbusters"
paid homage to

duct tape, fans
went into a frenzy.

***

because you asked for it,

they're putting
more duct tape tales

to the ultimate test.

Oh, it's for real.

***

so what do you have in mind?

I see in my mind EEG eye

a chasm, wide and deep,
spanned only by duct tape.

A duct tape bridge?

That you and I can walk across.

Sounds dangerous.

Exactly!

A duct tape ding Hi's one thing

but replacing steel and stone

in the tape's magical adhesive
and load g incapabilities

are about btctosttog d
thesthe ultimate limit

but we'll cross that
bridge when we come to it.

***

I think we should run
duct tape through

the paces in the shop downstairs,

a series of bench
tests, if you will.

Okay.

Look, obviously we are
already pretty familiar

with the awesome
power of duct tape.

But if we're going to
make a bridge out of

this stuff that safely su
spends us above a chasm,

we have to determine a couple
of things right up front.

One, how much do we need
to support our body weight?

Two, how will we
anchor the duct tape

to the sides of the chasm?

That's with we're about
to test and figure out.

So where do you want to begin?

Let' say we stretch
out a single strand

and see what it takes to break it?

Sounds good. Let's do it.

Step one, a single
strand strength test.

The role will be played
by a digital force gauge.

I will pull on the
duct tape with the hook

and it will tell me how
many pounds of force

it takes before it breaks.



T I don'hemean it's hurting.
Just the anticipation.



Oh!



Wow. That's more than
I would have thought.

Me, too.

They might be well acquainted
with duct tape's awesome qualities

but it still has the
power to surprise.

I didn't realize

the duct tape was going
to be that strong.

That means that we could, in fact,

build a bridge in theory

with, like,

three or four strips of
duct tape and nothing else.

Huh.

That little laugh means

Jamie's already plotting to
put that theory to the test.

I want to stretch four
across and sit on it.

-And sit on it?
-Yeah.

Okay.

One strand snaps at 67 pounds

so 4 strands should hold a


You ready to sit on this?

I am.

All right. Go for it.

Slow down. Slow down.

So you're hanging.

I am.

I would say I'm off the ground.

That's pretty stunning.

With a combined

load bearing capacity
of more than 260 pounds,

the four strands support Jamie.

But they're drooping
more than his mustache.

You droppin o6 et30fer t.Veee fdo

that's quite a bit.

Yep. Supporting me
but I have to say

four pieces of duct tape
does not a bridge make.

We're now going to try a strand
of eight pieces of duct tape

and see if we get less droop.

Will adding more tape
help the droop factor?

***

I'm ready.

With Jamie sitting
pretty on the porch,

Adam runs a tape over the tape

and the good news isn't good.

Four feet of droop instead
of five feet of droop.

You would think that

the doubles of the quantity
of duct tape would,

what, cut the amount of
droop in half but it didn't.

Hopes of a successful
bridge are saggy

until Adam lays on an idea.

***

then weaves a little magic.

I'm trying to tease out

structural qualities in duct

tape to eventually yield for me

-- this is my goal, a bridge
that I can actually walk on.

It seems they might have
finally found their footing.

It doesn't feel that bad.

Do you want to try it?

No. I can see.

With the weight distributed
across all five strands,

the extreme sag might be solved.

Looks good.

With handrails, you
could walk across.

With five, you have a
good safety factor.

This stuff is amazing.

We might be able to build
a bridge out of this.

I think you're right.

Look, ma. No hands.

***

so last time we built a
cannon out of duct tape.

What are we doing with this time?

***

there's one more very important tool
to be carrying along in the car.

Duct tape. Yeah, sure.

If you get into a
minor fender bender,

you could hold things together
until you goat the mechanic.

Exactly.

I hate to ruin your party
but that's not a myth.

That works.

I have used duct tape to
fix my car in the past.

I think the myth
lies in the extreme.

Just what are you getting at?

I have some action
plans for you guys.

Everyone knows

a few strips of duct tape can
mend a minor automotive mishap.

But can it cure the most
extreme car catastrophe?

I have a plan. I'll
tear apart a car

and see if you can put it
back together with duct tape.

Good plan.

Sounds like a challenge to me.

Oh, you don't even know.

Putting the car back together
is only part of the challenge.

It will also have to stay
in one piece at top speed.

And so yet another unfortunate
automobile enters the driveway of doom.

All right.

Time to wreck this car.

This little adventure is really
going to put duct tape to the test.

The boys are going to have to put this
car back together after I destroy it.

Now, they think it will be easy.

I think they're underestimating
my destructive powers.

To really test the tape,

she wants that car in as
many pieces as possible

and has developed a disturbing
appetite for destruction.

I love destroying cars.

Breaking glass.

Crunching metal.

Awesome.

But when it comes
to raising the roof,

even Kari's dark side is defeated.

There's tools made for this.

I think I have some
friends that could help.

***

cue a crew of San Fran's finest

ready and willing to help Kari to
complete the deranged dismantling.

Just in time.

That is awesome.

What is that?

These are hydraulic cutting tools

and that is cutter
spreader combination.

These are cutters and use
them to cut apart the vehicle.

The tools are designed to
quickly open up vehicles

and free accident victims.

This makes my tools look silly.

***

narrator: The blades bright down
with more than 12,000 pounds o

Whoo! I love it.

Thank you, guys, so much.

This is really going
to ruin their day.

Great.

Bye, guys. Bye.

***

it took me a sledge hammerr, sa

tape to put it back together.

Boys!

Hah hah hah hah!

Os car.

Convertible now.

Here are your tools.

That is an impressive amount

eard oduct o this

tapesed to, like, you

know, tapen mper or fix a hose

but you know know, w not all nce.

They're in a sticky situation.

Kari's done her job real wel

she cut key structural
points in the car.

It is important to
get it straight.

Aa

this holds the doors on.

The roof on top and keep
the windshield in place.

This is where the duct tape
will have to prove itself.

Soon the air is filled with the
sound of ripping duct tape.

Aa

duct tape is essentially
made of three layers.

Vinyl layer on the
outside to contribute

to the water proofing qualities.

The fabric structure to
give it the core strength

and a natural rubber
pressure sensitive adhesive.

Generally comes in black or
silver and about 1 7/8 inches.

Aa

it can be duck tape, hurricane
tape, gaffer's tape,

tank tape and rigger's tape.

This is just part of the team.

The cut up car is
coming back the life

much to Kari's surprise.

I can't believe how quickly
you're getting this car together.

Just wait. We have made
a few improvements.

Is that a window from the door?

Yep.

Don't drive too fast.

With the redo complete,

Kari can't hide her admiration.

I'm going to drive this car

to give the duct tape
car a spruce up.***a

now the guys if they drive
will drive gingerly.

Aa

they don't want to see
the doors fall off.

Aa

***

and I want to see things fly.

Later, the highs and
lows of a bouncy bridge.

And next, can Kari demolish
the duct taped car?

Aa

Kari, Tory and Grant's duct tape car
fix is ready for the ultimate test.

Sorry. I might have got
a little carried away.

Hey now.

And so it's off to a place

where the "mythbusters" performed
many crimes against inanity.

What took you so long?

What we'll do ***

is set up a course at
the alameda runway.

Start! Go through a
little "s" curve,

turn, hair pin turn and then
through a bump, a bump, a bump.

And a really tight turn.

The idea here is
to subject the car

to as much stress as possible
in the form of g force.

This is duct tape car on the
duct tape classic grand prix.

Lap one. Go ahead.

Okay. Here we go.

Car number 17 with
Byron at the wheel.

Into turn number one.Come on!

Kari drives as though the accelerator
is duct taped to the floor.

Now into turn number three.

Too much turn.

Through the crazy cornering,

the car is subjected
to tremendous g force.

Over the bump. And
back to the beginning.

We're going to die.

Okay. Lap number four.

Go, go, go, go!

I got to say right now, the
car is looking perfect.

That's five laps so far.

You are looking great.

Even your hood detail is still on.

Kari's doing between 40
and 60 miles per hour.

In a car with no
structural integrity.

Everything from the
roof to the doors

is being held on only by tape.

One wheel in the air.

Take it easy there, Kari.

Last lap.

And for the checkered flag.

You would think I would have --

it's a duct tape classic.

What do you know?

The duct tape car has
stayed the course.

All right.

That was ten laps.

Whoo! You know what?
It actually made it.

We survived.

Hair pin turns, "s" turns,
sandbags, I took air.

Still, duct tape is holding up.

That was on flat ground.

Now it is time to take
it to the next level.

We are sending it off road.

And in addition, it looks
like it's going to rain.

Okay. Let's go.

Maybe getting off the beaten track

will bring this myth unstuck.

Mad Maxine floors it.

Over there. In the brush.

After several soggy minutes,
thumping and bumping,

this duct tape myth
suddenly stalls.

Car's dead.

Only on "mhb,"usters everyone's
worried about the duct tape

but the only thing that's
busted is the engine.

The tape hasn't budged.

G force alone should have
torn that thing apart.

The mood ornament
did not fall off.

I have to say, I think we have
to call this one confirmed.

Absolutely confirmed!

Totally confirmed.

Aa

Jamie and Adam have worked
out the amount of duct tape

they'll need to build a bridge

but before they decide on a design

they need to know exactly what
space they'll be spanning.

This is our chasm.


wall to that wall.

It is this distance
that we have to span.

This 50-foot drop e last
featured in the seesaw saga

when it became the launching
pad for a little girl.

After sizing up the gap --

-inside is 104 and 2 inches.
-Awesome.

They return to base
for the plan to span.

All right.

How do you want to do this thing?

Well, I figured this is
basically a rope bridge

so let's make a bunch of
rope out of duct tape.

Okay. I could see that.

We make ropey strands and bind
them together to make the floor

and then, you know,

another couple of probably
thick strands for a railing.

That would actually
be pretty stable.

And then we could have some big ones along
the side stretched to make it stable.

The small-scale test showed
five strands of duct tape

eight layers thick can support
their weight without major droop

but to be safe they'll make
the walkway ten strands thick.

Adam's anxious.***a

I'm about to construct
what I hope will be

the ultimate automatic
duct taping machine.

Look out.

Adam's just itching to invent.

Step one, another cylinders which
fit together Russian doll style.

Attached to a metal strut.

Okay.

Which is welded to
a support frame.

Looking great.

Add duct tape and
behold the duct-o-matic

dispensing ten strands
simultaneously.

***a duct tape cable.

At this point, I trust
my life to that.

I can't wait to
show this to Jamie.

He's going to be like, well,
it's a little over elaborate.

Don't you think?

Check it out.

My ten-roll single pull
duct tape cable maker.

That seems to work.

I mean a lot of different
ways you could do it

but six one half a
dozen the other, huh?

Yeah.

With Adam basking in Jamie's
effusive admiration,

they measure out the
required distance.

Okay. That's 104
feet to right here.

And get down to some serious bridge
building starting with the floor.

Like we're making the
world's biggest sweater.

Hold on. Slow down.

That's a workout.

That's number five.

Let's bind them together.

Those five strands,

each one ten layers thick are stuck
together to form a narrow walkway.

It may not look like much

but it just might save my life.

Next, Jamie produces a pair
of handrails with a Twist.

Perfect.

The rope-like cable should
give them a good grip.

I like the way it seems
kind of nice to hold on to.

Yeah. I totally agree.

That's ten strands.

With the walkway,

handrails and stabilizing rails
complete, they're all set.

That's the great thing
about a duct tape bridge.

It's so portable.

Just fold and roll.

That's not bad.

Should we go build
a bridge with it?

I think so.

Okay.

***

it is the "mythbusters"
second duct tape special.

All right. Kari, why
do you look so happy?

I love the next myth.

And what is that?

This is sent in by
tons of viewers.

It is that you can stop a
car using only duct tape.

What?

Video two parts to the myth.

The first one is based
on a practical joke

that you can duct tape a car to a
telephone pole and won't go anywhere.

Technically not stopping a car
but preventing it from movie.

Technically.

The second part is stopping a car.

It is that you can use
one roll of duct tape,

build a barrier and catch a
car going 60 miles per hour.

Now that one I like.

Right?

Right.

The first part of this myth
is a prank par excellent.

A devious dude duck tapes a
friend's car to the pole.

He steps on the pedal
but can't escape.

***a

I think the whole point
of this is to see

how to keep the car stationary
with the least amount of duct tape.

All they need for this one is
a car and a convenient pole.

***

this is the last time
we carpool together.

Thanks the Adam's earlier test,

the team already knows the breaking
point of a string l strand of tape.



All they have to do is determine
the car's pulling power.

And work out how much tape it
will take to counter that force.

What we'll do is get
the force meter,

strap it to the car and
attach it to the pole.

Grant will drive forward.

At the point it stops
driving forward,

***a that's the force.

***

***

ccc

Max is 1,300. ***

arra****ulhe c* pls 1,300

strand of ducteaapbr

so in theory, wrapping the
car ulushobe jimt enough

to stop it aribe viy.Wang

go for 20 and see if it will work.

I think the duct tape might
actually stop this car.

Tory and Kari play a prank.

For science, you understand.

Hey, you kids. What are
you doing to my car?

I have a sneaking suspicion

there are prankster victims
everywhere blaming "mythbusters"

for this myth being true.

And so we say

in the hope of pranksters paying

the slightest attention,

please, don't try this at home.

What's this?

On your head.

Okay, Grant. Time
to rev up this myth.



A few breaks there.

It is holding the car in place.

Floor it!

Stopped the car with duct tape!

Yes!

***a

***b

I think it's confirmed.

Just five rolls of tape were enough
to keep the car in its pole position.

One strand broke. That was it.

Look at that.

I cannot believe this
myth is confirmed.

Confirmed!

Yeah!

Confirmed!

Yeah!

***

***

ccc

Adam and Jamie are rolling
out their duct tape bridge.

These five strips of
duct tape are our bridge.

We have walkway, two handrails
and two stabilizing rails.

Why are we hooking
them up to this truck?

***

if it stretches it droops and

we'll preassemble it up here
on the trucks and prestretch it

before we put it across the span.

They'll attach the walkway,

handrails and ropes to
steel anchor points.

T ti is o me t, melkwa

they'll anchor either
end of the elbridge

and help keep theuc
tape under tension.

Ches thtretg ine duct tape
should prevent any sudden sag.

With the bridge suspended
between the pickups,

Adam and Jamie go through their
pre-walk stretching routine.

I think this is going to work!

Hoping to take all the
elasticity out of the duct tape

before they venture out
over a 50-foot drop.

Prestretching this bridge is turning out
to be a little trickier than we thought.

Different components are stretching at
different rates under different loads.

We're just going to do the best
we can and hope that it works.

All right.

When they take their
first few practice steps

that's how you went to
grade school, right?

I don't want to do that.

It's immediately clear

they're going to need more tape.

I think we want to
add in some stringers

between these things and the floor

because you could be
like all -- dude, whoa,

yeah. See? I -- whoa!

This is going to be terrifying.

Duct tape cross struts between the walkway
and handrails will minimize wobble.

With the last-minute improvements,

the bridge is ready to go.


almost 400 pounds of the stuff

and the bridge is pretty much
ready to string across the chasm.

I marked a midpoint because in my
opinion once we pass this point

I think we are home free.

See, this point being the farther is where
the bridge can cause us the most trouble.

It could possibly turn turtle

and flip us over when we get here.

Getting the preassembled bridge across
the chasm is a feat in of itself.

They haul it 100 feet
to the other side

and use heavy machinery
to do heavy lifting

all without damaging
the duct tape.

It's one thing on the ground.

Quite another going it
go up across the chasm.

Not many people know

that Jamie has performed
surgery with a forklift.

***

it's beautiful

Adam and Jamie g
finally bridge the gap

between duct tape fantasy
and duct tape reality.

You know what?
That is my my friend.

That's a bridge.

That is a bridge.

Always a good day for us

when we're able to use tools and

materials in ways for which
they were never intended

and duct tape bridge, well,

I dare say the guy that
invented this stuff had

no intent whatsoever to use
it to make bridges with.

Will it work?

S the'eronly one
way to find out.E'

***

don't try anything you
have seen on the show.

We are what you call -- experts.

***

just five rolls of duct
tape can keep a car parked.

Then, Grant, Tory and Kari want to
super size this automotive myth.

How crazy is this myth to catch a
car with a single roll of duct tape?

Yeah, that does seem
a little ridiculous

but you saw how well it
held the car together

when you were driving
around like a maniac.

***

versus a car going 60?

I have seen crazier
things on the show.

Let's do it.

They're on the road again.

Telephone poles are few
and far between out here.

So they'll use something
a little more concrete.

We're setting up k-rail in an
arrow formation for two purposes.

One, it's going to hold our single
roll of duct tape car catcher

as well as serve as a barrier for
anything that may go out of control.

The tape is wound round
half-inch thick steel rods

forming a single strand ***

and then this fan fable doesn't just
look dubious but patently ridiculous

and then some.

Duct tape can do
that lot of things.

But stopping a car at 60
miles per hour with one roll?

I seriously doubt it.

Ready to put your life
on the line for science?

Oh, I'm ready.

Do we really need helmets, though?

Yes.

I'm going to watch
from a safe place.

I'm ready. Are you in position?

Stand by.

Okay.

This is single roll of
duct tape on your go.

Okay. Here we go.

Tory hits the gas.

Stop!

The car hits the duct tape.

And the myth hits the mcatom.

Okay.

So maybe you didn't
need the helmets.

I didn't get up to 60 miles
per hour. That was like 40.

Oh well. I can't believe it broke.

Couldn't stop a car.

Let's do what we do on the***a

show and super size it.

Yeah, but I mean, we can build a
wall ten feet thick with duct tape.

Where do we draw the line?

That's totally impractical.

Maybe 100 rolls of duct tape.

Sounds great.

This is how we'll do it.

We have two pipes
on either side here

and wrap the duct tape around it until it's
thick enough we think it will stop the car.

Back at alameda,

they have a solid wall three inches
thick made from 100 rolls of duct tape.

That is one thick
wall of duct tape.

No one's willing to drive
into this duct tape barrier

so they've got a plan.

In order to get the car
to hit the barrier,

we are going to tow it.

Tory's made a tow bar.

***

now at the bottom of the
wall is a steel plate

and connected to that
plate is a pulley.

The tow cable goes
through the pulley

so that as we tow the
car towards the barrier,

it is going to want to
center right on that pulley

and aim right for the wall.

And just in case the
cable comes loose,

the car goes awol -
how I have missed you so.

Grant's brought
along an old friend.

What this radio is doing is sending
a signal to the receiver on the roof

to control a valve down here.

The valve provides
air to the cylinder.

When I turn this off,

it actually takes the foot off the
brake and allows the car to roll.

When I go to safe, it closes
the brake and the car stops.

With the car under Grant's
control, they're good to go.

Got the car right here running.

The brakes are on.

I just need to flip the switch

and disengage the brakes
and it is ready to go.

At that point, the tow vehicle
will hit the accelerator

pulling the car down the track headed
straight for our wall of duct tape.

Here we go, Kari.

Brake is off.

Ease into it. Three, two, one, go.

Here it comes.

The pickup picks up speed.



The test car hurdles towards the
tape with duct tape destiny.

At the last second --

the experiment hits
a bit of a snag.

Somehow the car hit everything
except the wall of duct tape.

What happened?

I thought I saw the tow cable
slip off of the guide bar

but just a car length
before the k-rails.

The cable came through so late Grant
didn't have time to hit the brakes

but there is some good news.

The duct tape barrier's undamaged.

We are going to go back, take this
face your, figure out how to fix it,

we are going to try it again
because we are not giving up here.

Looking great.

Right on target.

Still ahead.

More duct tape demolition.

***

***

Kari, Tory and Grant want to see

if a duct tape pe r barrier
can stop a speeding car.

But on their first attempt,

failure was the option.

We lost the connection
between our tow vehicle

and this vehicland veered
to the right and crashed.

Now what we are going to do
is put a rope clip on there.

We moved the break away line
up to the tow vehicle itself.

If anything is
caught in the pulley,

that cable will break away
and everybody will be safe.

They're not about to let rain
dampen the quest for duct tape data.

Here we go.

The test car is soon
taxiing down the runway

with Tory and Grant
in hot pursuit.

It's got it!

That was awesome!

Yeah!

Once again, the car
caught the k-rails

but it also wiped out
the duct tape wall.

Didn't it?

Looks like the duct tape wall

wasn't strong enough
to stop the car.

Check it.

Oh, no.

The wall is still together.

We've got a problem.

It broke away from the k-rail.

You know what?

I think we better take a look at the
high speed and see what happened.

All right.

The duct tape wall stayed intact
and it ripped it out of the k-rail.

I can't believe that.

I mean, that's a huge amount of
shock that absorbed right there.

While the guys are absorbing the
shock of another failed test,

the fact that the wall's still in
one piece after being hit by the car

means this myth has a definite
whiff of plausibility.

***

we're about to find out if Jamie

and Adam can walk the walk on
the world's most unusual bridge.

We have spanned 100-foot chasm
with nothing but duct tape. Soon,

we will take that long walk
into duct tape history.

And just in case that
walk becomes a plunge,

a crane-mounted safety rig will
turn them into human pinatas.

I'm having a great
time. This will work.

***a

I know that this yo-yo fall
arrester will save my life

but if it has to save my life,

I'm going to fall
and pull up short.

Either way it is terrifying
and going to hurt.

It is not just pride that makes
me not want this bridge to fail.

The small-scale tests
say it should hold.

It should be fine.

It is duct tape. What
are you going to do?

Adam's a little lighter
than Jamie and going first.

It will be less
stress on the tape.

Just remember, if you
hear a ripping sound,

run really fast for
the other side.

Thanks for nothing.

-Good luck.
-Thanks.

Here we go. Nearly 200
rolls of duct tape,

a 50-foot drop and one


All for the glory.

All right.

Here we go.

Hey. I don't mind saying
I'm kind of freaked out.

Oh.

All right.

It feels pretty solid and
not hard to stay upright.

The handles are
working just great.

My heart is beating about


People walk on bridges
like this every day?

This is terrifying.

Nearing the middle of the bridge,

he enters the real danger zone.

This is where the duct
tape's most likely to fail

and flip Adam into thin air.

I'm passing halfway.

I'm past the danger of turtling.

But dude, this is rough.

Got about ten feet to go.

Now it feels much more
stable and I feel okay.

Two and a half minutes
after starting out,

Adam sets foot on solid ground.

Hey!

Good to see you.

Oh man. Feels good.

Good land. Good, solid ground.

It is another world first.

He's just crossed 100-foot chasm
on a bridge made of duct tape.

I wouldn't have called this

but actually felt quite
stable out at the center

and for the first 15 or 20 feet,

like the first third and last third
were the roughest test where itoves

around a lot more than feels good.

All right. Your turn!

Jamie steadies himself to
make the return journey.

Adam found it terrifying.

I'm going to find it
worse than terrifying

because I really
don't like heights.

His slightly heavier frame will
put added stress on the duct tape.

Oh gosh. Here we go.

And as soon as he puts
the best foot forward,

it's clear this won't
be a smooth crossing.

Now I know what it feels
like to be a spider.

Or maybe is it a bug in a spider

that really is quite hairy.

A third of the way across

and Jamie's struggling
to maintain his balance.

This wiggling around is

kind of something I
don't want to be doing.

Honestly, I'm not sure
he's going to make it.

Both Jamie and the bridge are
teetering on the brink of failure.

There's more ripped tape.

***

Tory, Grant and Kari are hoping

it will be first time lucky
for the duct tape roadblock.

It is the same set-up with one
or two heavy-duty add-ones.

We have shackles raided
at 30,000 pounds.

***a

this should do the job.

With Tory's tow bar good to go,

and Grant's rc braking system car
number three's ready for take off.

Are you ready?

I'm ready.

Okay. Brake is off. Here we go.

In three, two, one. Hit it.

Good. Got a good start.

Getting up good speed.



Kari picks up the pace.

Looking great.

Right on target.

Really good.



Oh, we are going to
do it this time, dude.

This is it!

Bull's eye.

The car hits the
duct tape dead on.

Yes!

That was worth all that stuff.

Oh my gosh.

Look at that.

That -- right through.

What would you say? Three inches?

Two and a half
inches of duct tape?

Easily.

That's three inches for sure.

Artora buc tto dhet pe d
didn't give up without a fight.

Despite being hit with a force
totaling nearly 3,000 foot pounds,

the duct tape stretched
like a piece of elastic

before finally snapping.

Well, stretched four, six
feet before it gave up.

Like with all that
time absorbing energy.

Still, an amazing
product but, nope.

Not able to stop a car.

Now, sure, we could have
made one two feet thick.

Let's face it.

We bust up a k-rail and that
stuff is made to stop cars.

Looks like this is busted.

We found something duct
tape finally can't do.

***

man.

Duct tape left over
to fix that thing?

***

meanwhile, Jamie's
trapped in a nightmare.

He's finding out the hard way

that one of duct
tape's main features,

its elasticity, isn't so great
when you're 50 feet off the ground.

Every movement triggers
more vibration.

It's taking all his strength
just to stay upright.

I'm going to sit here
and rest a second.

Okay.

Despite prestretching,
the tape's losing tension

and he hasn't even made it
to the perilous midpoint.

Hey, you passed the halfway point.

Is that all?

It feels like I've
been going for a mile.

And I don't mind saying
I'm hyper ventilating.

The bridge is so unstable he
must inch his way to safety.

It's taken him four
times longer than Adam

but Jamie finally makes
it back to terra firma.

Ladies and gentlemen,
they're made of brass.

James Hyneman, congratulations.

That is absolutely awful.

That's really saying something,

given the other ars he's faced
in the name of mythbusting.

I've been buried alive.

I've been charged by
great white sharks.

This thing here is terrifying
in a totally different way.

It's not so bad walking
across something like this.

Just like going over
the heights with it.

The problem is that
you're just on the verge

when you get a little
ways out into it of,

like, losing balance.

It's -- it's like there's
nothing solid to hold on to.

So, you know, walking across
it is this constant, intense

correction to try and dampen out the wiggly
waves you are setting up on these ropes.

Viewing both walks,

it is clear Adam was on
a much firmer footing.

Why was it so wobbly for me?

Could be me.

Could be the material, though.

We do know that it stretches
out quite a bit under a load

and Adam did, in fact,
put a load on it.

One way or another, it worked.

But it's not an ideal
material for a bridge.

***

I got say I'm pretty
impressed with this stuff.

It's a bridge. It's a rope.
It can sh**t. It can float.

Just two sides. And
infinite possibilities.

Verdict, is there anything
duct tape can't do?

Two episodes and
counting, almost nothing.

***

we're going to find crazier
crap to do with this stuff.

Yeah, but that's another episode.

Let's go.

All right.

I think we need to get
airborne with this stuff.

Absolutely.
