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 gun.
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.
10, 12, 13. Killing me.
T I don'hemean it's hurting. Just the anticipation.
63.
Oh!
67.3 pounds of force to break it.
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 180-pound Hyneman. Right?
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.
108 feet from this 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.
67.3 pounds of force to break it.
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.
1,000 rpms.
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.
196 rolls of duct tape, 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.
60 miles per hour.
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 175-pound mythbuster.
All for the glory.
All right.
Here we go.
AmericasCardroom.com brings poker back Million Dollar Sunday Tournament every Sunday
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 175 times a minute, though.
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.
20.
Kari picks up the pace.
Looking great.
Right on target.
Really good.
40.
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 shoot. 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.
