Do not try what you're about to see at home.
We're what you call experts.
On this gripping episode of Mythbusters...
Adam and Jamie spin out...
I can feel the breeze.
in a double bill about dangerous driving.
Freaking hell, that's hilarious!
First, is it true that some types of shoe...
Seriously, stop laughing!
make you worse behind the wheel.
Then, Adam's bladder is under pressure...
Okay, I can't even tell you
how badly I have to pee right now.
as the guys test if being about to burst
is as bad as being boozed-up.
That was bad, @#$%…….
Meanwhile, Tory, Kari and Grant are stuck,
tackling two tall tales about super adhesive.
This glue is incredible!
Can the superb glue
really turn a room upside down?
We'll be like rock stars!
And then, in a full-on head-on crash...
That is a headache!
Could this ultimate sticky stuff
really stand in for our seat belt?
Who are the mythbusters?
Adam Savage...
I got the chicken!
and Jamie Hyneman.
Between them, more than 30 years of special-effects experience.
Together with Grant Imahara...
Save yourselves!
Kari Byron...
That was awesome!
and Tory Belleci.
We're gonna die!
They don't just tell the myths,
they put them to the test.
At first, buckle up,
cause the mythbusters are going to hit the road.
That sounds like fun.
What's the first one?
I'll give you a hint.
How does that fit in?
Well, the myth is that there are certain types of shoewear
so poorly designed for driving that
they make you into a dangerous driver.
You don't actually think I'm going to wear those, do you?
In fact, I do.
I thought you would respond that way,
but I got something that will make you feel better.
- What's that? - Our second story,
which is that driving with an extremely full bladder
is supposed to be just as bad as driving while drunk.
And how's that gonna make me feel better?
Because I am gonna be the test subject.
Okay, that does actually make me feel better.
I thought it might.
So, it is a duo of driving myths.
Could it really be possible that
driving under the influence of a full bladder
is just as bad as driving when you're drunk?
But first up,
could it be true that certain types of footwear
will turn you into a hazard on the highway?
Well, supposing you do actually manage
to get me in a pair of those,
how do you propose we test them.
Why don't we do it like this,
we each wear a strange piece of footwear
with our foot all the way down on the accelerator.
Then we time how long it takes
to get from the accelerator all the way to the brake.
We pick the three worst shoes and test those
on a closed course under extreme conditions.
That works.
So the guys will put their best foot forward
with six shoe types
that already look dodgy to drive in.
Flip flops, high heels,
wedges, platform shoes,
elevator boots, and snow boots.
We're gonna choose the three worst,
the three that will affect your driving the most,
and we're gonna do that in small scale here in the shop
by putting on each pair of shoes,
and getting in the car while it's stationary,
and timing how long it takes us to move the foot
from all the way down on the accelerator
to all the way down on the brake.
The idea is that
the more a shoe slows a driver's response time,
the worse a driver that person will be.
All right!
So the guys are waiting for some reaction time tests.
Cool.
Here is how it's gonna work.
When that sign turns from green to red,
a timer starts.
I'll be sitting in the car
with my foot on the accelerator pedal.
The moment I see that timer start,
my goal is as fast as possible to get my foot
off the accelerator and onto the brake
which stops the timer.
And that's our reaction time.
Indeed.
And the three pairs that cause the slowest reaction times
will make it through to the real world road test.
What's first?
Flip flops. I like flip flops.
Well, there's entire states where people wear these 24/7
like Florida and Hawaii.
Who knows how dangerous it is to drive there?
As their name suggests,
flip flops are hardly precision footwear
which Adam discovers.
0.71.
To eliminate any little performance glitches,
the guys will both test each pair of shoes.
0.55, the gentleman is fast.
Then, average their results,
to sort the shoes in reaction time order.
High heels.
They may hurt.
But nothing makes my calves look better.
They have chosen footwear from every walk of life...
1.28.
whether it's high style heels...
I think production came up with a story
just so they can see me in these shoes.
extreme elevations...
I feel like I'm able to actually walk
a lot faster in them.
It's probably an illusion.
I can feel the breeze.
even the Arctic circle.
All right, bunny boots.
Ready when you are.
I got my foot stuck behind the brake.
And after a full day of testing...
0.51. Nice.
the mythbusters have all the reaction time data...
0.53. He is in the zone!
and embarrassing flashbacks...
Those are fabulous.
they could ever need.
0.54.
What have we got?
Well, it is actually really close,
the three worst ones were snow boots,
high heels, and wedges.
Those are the three we're gonna be testing on the road.
I'll be darned.
High heels, wedges, and bunny boots.
The values that we got from these boots
are quite close to each other.
But this was a controlled test in the shop.
Out of the field
when we're doing sophisticated driving maneuvers,
the difference might be much greater.
I would put my money on the bunny boots
as giving us the most amount of trouble on the road.
Coming up, Kari, Tory and Grant
have themselves a sticky situation.
Now, ever since we started testing duct tape myths
and doing all things duct tape,
all the fans want us to test another substance.
You mean super adhesive.
Exactly. They think it's so amazing
that it can do all these crazy things.
All right, so, like what?
Super adhesive seat belt,
and the old classic, upside down room.
Dude, sounds like it could get messy.
Super adhesive is the perfect glue
when you're hanging out for a quick fix.
But can super adhesive really let you turn a room upside down
or stick you safely to your seat
if you have a car crash?
You know, these all sound great,
but first, I'd like to know what we are up against.
Yeah, the fans got some pretty outlandish claims.
Before we dive in,
I'd like to do some tests,
see, like how much mass can it carry.
All right, sounds good to me.
With science on the menu,
Tory muscles together a rig
designed to see how strong the super adhesive really is.
So, I built this oversized barbell
that can take up to a thousand pounds
that we can lift with our forklift.
It is a heavy duty rig,
especially when you hear what it is up against.
All right, so this first test is just one drop, right?
One tiny little drop.
Somehow I thought it would be a bigger drop.
Yeah.
Yep, it's just a single drop of glue.
But will that be enough to raise the bar?
All right, I know the super glue is strong.
And these are near ideal surfaces.
But we're talking about one drop.
My guess, 250, maybe 275 pounds.
To find out,
they'll add weights to the bar until the glue gives out.
The question is,
how many pounds till it grounds?
All right, 100 pounds.
- Yes, 100 pounds. - Looks like it holds.
It's so far so good,
and two lifts later...
200 pounds. Do it.
- No problem. - Nice.
It could have Grant's prediction covered.
Okay, this is 300 pounds.
Nice.
That's pretty surprising.
One drop of glue, 300 pounds.
But the test ain't over...
You got any more in you? You could do it.
until the drop drops off.
- 650. Let's do it. - Do it!
- I can't even believe it. - No problem.
- I can't even believe it. - 650!
How much further can it go?
I don't know, let's see if we can go up to a thousand.
Oh my God.
So then, it's 650 pounds is the strength of one drop.
Seven drops should be enough to lift
the weight of your average American car,
which is about 4,000 pounds or two tons.
We're gonna see if that works.
I have so much faith in this glue.
I really do think this car
is gonna go up off the ground with seven drops.
Six, seven.
All right, seven drops of glue.
Kari climbs into the hot seat and it is go time.
All right, Kari.
- Holding. - Yes!
It works! It's off the ground.
No way!
Seven drops is enough to lift a car.
That is insane!
Oh my God. We lifted a car with glue!
This is amazing.
We lifted a car with seven drops of glue.
Now, I knew this stuff was strong,
but I didn't know it was this strong.
But this is Mythbusters,
we're not gonna stop here.
We have a whole bunch of tests just to find out
how well this glue works.
Isn't that the truth, with upside down rooms
and seat belt stand-ins,
there's a lot more to come on stunned.
I never glued a bed to the roof before.
For some years, the headlines have had it in for high heels.
But does fancy footwear really lead to dodgy driving?
Well, in the shop, Adam and Jamie's
health hazard heels were just that.
But now it is time to see
if there will be a risk on the road.
So we got a closed course and a car
with racing harnesses in it.
What could be a better day?
And they'll super charge the testing
with a stunt driving shoe show down.
We brought out an old friend, Mark Ralph,
who is an instructor at the Alameda county EVOC training center.
Jamie and I are gonna line up
a bunch of complicated driving maneuvers.
Just remember, let the car do the work.
We can get really good at them.
And now.
That was nice.
And then we're going to see
if it's even remotely possible to do them
in some fancy footwear.
That is so much fun!
And there's more fun to come,
because those silky stunt skills
are gonna be the basis for our fancy footwear test track.
That's the end of the straight way.
And to say it's extreme is an understatement.
The first part of the course is accident avoidance.
The moment the light changes,
Jamie has to choose a lane.
Accident avoidance means not hitting any cones,
it also means not hitting any people.
After the accident avoidance
comes the forward 180
which we have been practicing.
He's gotten pretty good at it, too.
He's got a nudge this pedestrian.
Then he goes into a reverse 180.
Like that.
The reverse 180 leads naturally
to a zig zag slalom which requires
very precise application at both the gas and the brake,
so that might be very difficult with weird shoes.
And the whole thing gets timed.
So try and get the best possible time.
Yep, a time trial is the ideal way
to put the shoes through their paces.
And first up is the control.
The regular shoes benchmark.
Regular shoes, control test,
in 3, 2, 1. Go.
First one is working out great.
To make it through quickly,
you have to move your foot from pedal to pedal back and forth,
back and forth, back and forth.
It is working fine with the shoes that I've got on.
But, what it does with fancy footwear,
we'll see.
All right, well, your first one was 1'22,
second was 1'21.
I think that's your benchmark.
- Okay. - My turn.
3, 2, 1, go.
If any kind of alternative shoe
that was going to inhibit my ability to drive at all,
it's going to show up on this course.
How did I do?
1'17.
1'17. I've been hitting that every time.
I guess that's my benchmark.
That's pure fun right there.
They burn through their control laps in times
that the hazardous heels might find hard to match.
Super adhesive had set a really high standard.
It's off the ground.
We lifted the car with nothing but glue.
But could it fail at the first myth?
All right. So now that we have seen
the power of super adhesive,
what's the first myth?
All right, this myth comes from the '70s.
Apparently rock bands would go to hotels,
and pull these pranks.
And one of the pranks
is that they would glue the furniture from the room
on the ceiling.
Okay. The crazy part of this to me
is not just the logistics, but time restraints.
They would have had to do it, like overnight.
We should not only glue our furniture up,
we should do it within a day.
All right, let's get to it.
Rock stars have a history of hotel room hi-jinxs.
But can you really turn a room
upside down with super adhesive?
So this is the room that we're gonna turn upside down.
Now, it is built to code,
and has everything you would find in a hotel room.
We have a desk with a computer on it,
we got a light stand, we got a bed with sheets,
that ain't going to be easy.
We have a coffee table with a whole bunch of stuff on that.
We have a couch,
there's a plant, there's a television.
There's some dirty laundry.
I mean, this is one of our rooms.
Although none of these items weighs as much as a car,
what's critical is the materials they're made from.
These lumpy, absorbent surfaces
are a super adhesive's kryptonite.
It would be difficult to get them to stick to the floor,
let alone the ceiling.
And we don't have that much time.
But my guess,
the most difficult thing to stick to the ceiling...
the bed.
With the check-out clock ticking,
Tory needs to first stick the bed,
not to the ceiling, but to itself.
What I'm trying to do is get as much glue
on the mattress as possible.
And even then, I don't know how well it's gonna stick.
Seven drops was enough to lift a car.
But it's taken seven bottles
to stick the mattress to the base.
But eventually, it's set for liftoff.
All right, so this tool is normally used
to lift sheetrock up to the ceiling.
And we're gonna to be using it to lift furnitures
so that we can glue it to the ceiling.
I bet it was never intended for that.
It's a delicate balance...
There's something you don't see every day.
between letting the glue harden...
I never glued a bed to the roof before.
and staying on top of the clock.
This is sticky!
Get it wrong...
All right, let's see if the glue holds the bed up.
and this myth will come crashing to earth.
That's pretty solid so far.
That is awesome.
It's holding.
That is one upside down bed,
with a cherry on top.
But there's no let up,
because the couch is next to go.
And thanks to its nice, flat feet...
I think we may have pulled it off.
the glue is now two for two.
All right, go, go, go.
This corner is holding.
It is a "don't try this at home" classic.
Nice.
Next piece of furniture.
So you look at the TV, and you think no problem.
It's got a huge flat base,
probably got about a hundred square inches
of surface area to glue to, right?
Wrong, this is gonna be a nightmare.
See, underneath the TV is as whole waffle pattern.
Double that with the fact
that this is an old school, heavy, tube type TV,
and you got a problem.
A problem that's gonna swallow serious time.
But they can't afford down tools,
so up goes the coffee table.
My hands are burning.
And 40 minutes later, the TV is set.
But eventually, with all hands on deck,
the glue triumphs again.
It's like magic!
Now, with no time to hang around,
up goes the desk, complete with accessories...
Of course it's a hell, we are talking about 70s' lamps.
and the shag carpet.
It's awesome.
Just as they are wondering what all of the fuss was about...
Mother scratcher.
they get stuck.
Now, the potted plant is one of
the lightest things in this challenge.
But the soft wicker basket just doesn't want to stick.
So, plan is, keep adding glue until it does.
- How's that? - That's pretty.
One bottle becomes two.
Two becomes three.
But after an hour's work,
they finally stick it to the plant.
And there's still time for a few final flourishes,
before the result floors them.
This is so psychedelic.
Isn't this crazy?
Well, looks like you can turn a room upside down with glue.
And I think this is confirmed.
Confirmed, but very, very strange.
Later, will super adhesive hang on in a head on?
Here we go!
But next,
it's the ultimate hot rubber high heel ho-down.
We have been testing the myth that certain types of footwear
can inhibit driving to the point where they make it dangerous.
We have done some controls,
and we selected the three types of footwear
we considered most likely to cause that difficulty.
And now it's time to put this story to the test.
That's why we're wearing our driving shoes.
This is just wrong.
Seriously, this could be dangerous, so stop laughing.
Seriously, stop laughing.
- Yeah. - Shall we?
- Yeah. - All right.
These red heels were the third slowest performers
in the reaction time tests.
I'm great!
Humans weren't meant to wear these things.
But when the rubber hits the road,
how will these shoes affect Adam's 1'17 benchmark.
Okay, red shoes in 3, 2, 1, go.
Unfortunately for Adam,
there seems to be trouble from the very start.
Harder to get up to speak because I am pointing my toes.
Because of the narrow toe...
Okay, that was different.
and the towering heel.
Then to the reverse 180, ladies and gentlemen.
Shifting from pedal to pedal seems harder.
A little understeer.
Could Adam and his stilettos do stay the distance?
Come on, baby.
Let's get home.
Daddy's got a new pair of shoes.
And he completes the lap.
But how much have high heels hampered his handling?
How did I do?
I don't know, what do you think?
I feel like, if anything, I was a couple seconds slow.
Nope, you were right on the money, 1'17.
No way!
Yep.
Adam has matched his control time exactly.
1 minute and 17.
But will there be a spike...
All right!
in Jamie's lap time?
You know, I might have a problem doing this,
if I was more insecure than I am.
As it is, it's just another day on the job.
All right.
High-heeled shoes driving test
in 3, 2, 1, go.
Jamie tries his hardest to put the pedal to the metal.
I think I'm getting a sense to where this story comes from.
So far so good.
I mean, just look at these things.
They look awkward.
They feel awkward.
How do you think you did?
I don't know, about the same?
Exactly the same, 1 minute 21 seconds.
Well there you go.
Time to move it up a notch.
You ready with the wedges?
I'm totally ready and I'm sparkly.
Go!
Now in the shop tests,
the wedges had a worse reaction time than the stilettos.
I felt my foot catch a little bit on the accelerator pedal there.
But on the track,
I don't really feel,
like it is getting in the way.
for both Adam
One eighteen.
and Jamie,
1 minute 22 seconds.
Pretty much right on the money.
it's left them with one last pair.
The worst case scenario shoes of all.
- Let's do it. - OK.
Snow boots in 3, 2, 1, go.
In their shop tests,
these bunny boots showed seriously dangerous tendencies.
I got my foot stuck behind the brake.
The early signs are promising.
I might have lost some time there.
But the stop watch barely skips a beat.
One nineteen.
One nineteen, wow, just a little bit slower.
Not by much though.
I'd say that's also within an acceptable margin of error.
That's crazy!
And Jamie's snow boot time.
On the money. One twenty one.
And we've tried hard to crack the experiment,
that we tease out any difference in types of footwear
and their effect on your ability to drive.
We built a course that required
lots of precision driving maneuvers.
And after all this testing,
we can't discern that there's any significant differents
between any of these shoes and how they affect
your ability to percisely drive.
None of the shoe styles we tried made any difference
whatsoever in the timing.
No.
And I think we got a pretty good spectrum there too.
I got to say, this is busted.
They're really busted.
Let's get out of here.
You do realize that this is
what's gonna stick with us throughout eternity?
Still to come, Adam brings his bladder to the brink.
I really, really, really need to go.
But next, can super adhesive stand in for a seat belt?
That's incredible!
Do not try what you're about to see at home.
We're what you call experts.
In super adhesive heroics,
All right, go go go!
the glue is one up with one to play.
Time to put the glue in the driver's seat.
Ok, super adhesive seat belt.
This is the idea that you can glue
yourself to the car seat
instead of using a seat belt to survive a crash.
We really want to give this a chance for working.
Why don't we get a car with leather seats,
that way we have a better bonding surface.
Ok, so car with leather seats,
we set up a towing system.
We crash it into a wall at regular street speed,
and put one guy in a seat with a seat belt,
and the other guy with super glue only and compare.
Sounds good.
Sounds real good.
Anyone who doesn't use a seat belt
should get their head examined.
But if your seat belt's not working,
the fan site suggests that super adhesive
can secure you to your seat and even save your life.
To peel the sticky facts from fiction,
it is off to the runway.
Ok, this is just nuts.
We're gonna crash some cars, so that's gonna be cool.
With cars to be crashed,
the guys rolled out a classic Mythbusters' tow system.
Here we go.
Complete with concrete k-rails,
I can't believe they continue to rent these to us.
and a car with the right stuff.
So for a super adhesive seat belt myth,
we've got perfect car.
It's got lether seat to give us the best chance of adhesion.
We're gonna have two passengers.
One is gonna be super glued onto the seat,
the one in the other side is gonna have no super glue at all,
that's our control, so we can compare the damage.
The glue free control job goes to Buster.
Buster loves me.
I've sewn him together so many times.
Strapped under a standard seat belt, he's a little put out.
Deal with it, Buster.
Because taking on the danger of the super adhesive hot seat
will be a brand new mythbuster.
I'd like to introduce you to Buster 4.0.
He is a calibrated test instrument
or better known as a crash test dummy.
We're gonna break him in,
well pretty fitting, a car crash.
You can have fun!
We got to break in somehow.
To secure him in the super adhesive hot seat,
the guys stick both his jump suit
and his rubber skin to the leather interior.
We don't recommand you to do this at home.
This belted brace approach will give
Buster 4.0 the best chance of
success in a 35 miles per hour head-on crash.
All right, let's see how strong this glue really is.
In the tow car, Grant hits the gas.
The pully spin up towards the target speed.
20, 25.
Looking good.
And Buster 4.0 hopes he'll stick it out.
Looks like he came right out of his seat,
and smashed into the windshield with his head.
That is a headache.
That is not a good seat belt.
Well that's one way to break a new crash test dummy.
But you know what, the glue didn't hold at all.
His head smashed right through the windshield.
Except for the super adhesive seat belt,
the test worked perfectly.
We got our car with the two busters up to 35 miles an hour
and he crashed straight into the k-rail.
And no big surprise, the glue did not
hold him in his seat.
Now the Buster with the seat belt stayed in his seat,
had no damage whatsoever.
Yep, seat belt Buster is alive and kicking.
But his stuck up buddy is down for the count.
So what's gone wrong?
Looks like the materials didn't really stick to the seats,
but it is not the glue's fault.
The glue actually held.
Yeah I think we should try this again.
And maybe we cover with the seat with
something that's a little stronger and
put him in a material that's
gonna bond to it.
Incredibly, it was the material
that gave way on the seat and the clothes.
So for crash test two,
Tori's replacing their new car's regular seat
while Kari and Grant work on buster.
So in addition to replacing our lether seat,
we're also doing away with the jump suit,
replacing it with a rubberized wet suit.
Why you ask?
It make his look really good.
We get the best possible bonding surface for our glue.
And that rubber suit will be sticking to
a glue friendly fiberglass racing seat.
This way when we glue Buster in,
we're glueing rubber against fiberglass,
that's two nonporous materials.
So hopefully, he will actually stay
in the seat this time we crash the car.
In addition, the body hugging contours on the racing seat
mean there's more surface area to stick to Buster.
Oh yeah, there you go. That's a good fit.
But it's still a huge ask.
All right. This is test two.
Rubberized suit and hard plastic seat.
In 3, 2, 1, go!
10, 15.
Looking good.
20, 30 miles an hour.
Here we go.
It looks like he just got ripped right out of that seat.
Well, it's pretty obvious it didn't hold.
I'm pretty comfortable at this point
saying super adhesive seatbelt totally busted.
Which means that to put the super in super adhesive,
guys will have to take this myth to the max.
So driving drunk versus driving with a full bladder
seems like a pretty straightforward set of tests to me.
Let's do this one with the regular driving test style course.
You know, maneuvering, parallel parking etc.
Do it once with a full bladder,
once at the legal limit.
You know, we should be careful.
We don't want to rupture your bladder.
So what say we get a medical professional in to supervise.
Let's get to drive.
The dangers of driving while drunk are well established facts.
But a recent study has suggested that an overfilled bladder
can make driving more hazardous than being intoxicated.
Is it possible that being desperate to pee
makes you drive as badly as being over the limit?
Well to find out,
it's back to the asphalt heaven, Alameda.
It is a perfect day for driving.
Even if doing it dangerously.
Especially!
This time it's out with the stunt driving
and in with something all together more traditional,
a standard driver instruction course
with a few well chosen distractions.
Well you know, when you got to go, you got to go.
Allow me to show you our course.
It begins and ends right here with a one mile long
very tight straight away.
This will test my powers of concentration and endurance,
both with a full bladder and under the influence of alcohol.
So the next part of the course is a very narrow, snakey little curve,
- followed by... - The roundabout.
I will enter over here,
and make three complete circuits of it before exiting towards...
The slalom.
First he goes through it forward,
then he has to go out in reverse,
- and move on to... - A very straightforward,
yet most difficult part of the driving test,
the parallel park.
This is the ultimate maneuver before...
The final test,
which is where Adam will have to respond to random
change of these traffic lights that will tells him
which lane he has to swerve into at speed.
They'll judge Adam's driving
on how he preforms each maneuver as well as on his speed.
Adam can't exceed 20 miles an hour going down the straightaway.
When he's doing the obstacle course,
he can't exceed 25 miles an hour,
and can't hit any cones or any pedestrians.
Sober, with an empty bladder,
Adam peels off three practice laps to
get to grips with the course.
And by starting with the full bladder test,
Adam can enjoy his hangover once the testing is well and truely over.
What's with the urgency room tent?
Well this experiment about me getting
a full bladder is not as simple
as drinking a ton of water,
having to pee, and then driving.
The fact is, you actually can drink too much water
and create a potentially dangerous situation.
That's why this whole experiment's gonna be monitored by a doctor,
a urologist, doctor Hsu here.
He going to ultrasound my bladder
to make sure my bladder is pumply full
and yet, I don't die, which is, you know, good.
And get this, I already have to pee a little bit.
So we're like ahead of the game.
Your bladder actually has 174 ccs in there,
average bladder has about 350 to 400.
So you're about halfway full right now.
What you're saying that is I should probably drink
like 180 ccs of water right now.
- More like 300. - 300!?
- You'll be fine. - Ok.
It can take up to an hour before a drink trickles into the bladder.
Here we go.
300 milliliters down the hatch.
But a drink this size and Adam's bladder already half full,
in just 20 minutes, he's feeling the pressure.
How you doing?
I definitely really have to go.
But I think I should wait just a little longer.
Another ten minutes, and Adam thinks he is full to the brim.
Yeah I feel a lot of pressure.
However the ultrasound identifies room
for even further extension.
Ok. I am gonna drink a little more water.
100 mills, and five minutes later,
Adam really is myth busting.
I really, really, really need to go.
But before he goes,
I am ready for the full bladder test.
Jamie wants to outline the scoring system,
in excruciatingly slow detail.
The way we're gonna score this test is
Adam starts out with 100 points.
Every time he does something wrong,
we subtract some points.
Now each cone is worth five points.
Oh, my god.
I can't even tell you how badly I have to pee right now.
Every time he screws up the test, that's 20 points.
And every mile per hour over the speed limit he goes,
that's 5 points.
Let's do it.
Pedestrians that he can hit,
well, let's just say that's a lot of points.
We'll worry about that when we get there.
- Bladder control test in 3...2... - He's such a...
- Man, I am gonna get even. - One.
Two crash tests have proved it.
Super adhesive is no seat belt.
Not yet.
So far we have been having no luck
with our super adhesive seat belt myth.
The failures are in the clothing the dummies were wearing
or in the seats themselves.
What we need to do is focus on
the strength of the bond of the glue.
We're doing that by giving the
glue an ideal bonding surface--two steel plates.
One's gonna go on the dummy's back,
and the other is going to go on a special new metal seat
that I'll be installing into the vehicle.
By taking the fabrics out of the equation,
the guys are putting the glue
and glue alone to the ultimate crash test.
May not be the most comfortable seat.
But if it works, Buster's gonna be glad he has it.
We're back at the runway,
and we're all set up for another crash.
Because we wanna find out
if just the bond from super adhesive
can withstand the forces of a car crash.
This time there will be no clothes ripping,
there will be no seat tearing.
We're not fooling around.
We've two identical super flat steel plates.
This one is welded onto buster's frame,
and the other welded into the car.
And those two are stuck together with, yep, you guessed it.
But will the super adhesive finally keep buster in the hot seat?
All right, for our final experiment,
we have the same circumstances as before.
Here we go in 3, 2, 1.
Looks good.
We have one Buster just seat-belted in the passenger side
and we have our main Buster, with two metal plates,
super adhesive glued together, sitting in the driver's seat.
Straight headed towards the K-rails.
Hey, you know that might have worked!
It might have worked!
Well, what do you think?
The plate's still connected.
It actually withstood the crash.
That's incredible.
That's quite a super adhesive.
This is incredible.
He actually held on.
The glue was strong enough to withstand this shock.
I'm impressed.
So am I.
The super adhesive has stuck fast.
And during an impact, impacting 16,000 pounds of force.
Now in theory, super adhesive should have more than enough
holding power to withstand the force of the bump in a car crash.
And it turns out it does.
But this myth is still busted,
because unless you have a steel skeleton
with a 12 inch square steel plate welded to your back
and a identical 12 inch square plate
welded to a steel immovable chair in your car,
it's not gonna work for you.
Please, use a seat belt.
Well, not going home in that car.
Nope!
At the other end of the runway,
Adam couldn't be more ready
to test his bladder impaired concentration.
Bladder control test in 3, 2...
Man, I'm gonna get even.
One. Go.
The first challenge is the mile long straight way,
with a speed limit set at 20 miles an hour.
It is taking so long.
And it is clear that Adam's feeling the pressure.
Oh man, I can feel that pressure.
Next up is three turns of the roundabout.
Ok, here I go.
He only did two.
He's supposed to do three.
With his bladder becoming fuller by the minute.
Oh man, this hurts.
This is killing me!
There's a cone.
Adam's concentration is slipping.
This is awful.
Parallel parking.
I wish I was parking so I could pee, but I can't.
While he grimaces through accident avoidance,
Oh, yes!
it's the long, slow mile home,
Uranation is only minutes away.
lied with Jamie's deliberately distracting portable toilets.
That's the hardest of all.
But at last, he's finished.
How did I do?
Can I make a pee?
Well, first you got to do a piece to the camera I think.
- No. - No?
I'll see you in a minute, OK?
Adam is relieved.
But a full bladder absolutely
dented his concentration behind the wheel.
As for his score, well, that comes later.
We're making a point of not telling Adam
how he did on the full bladder test
so it doesn't skew how he does when intoxicated.
All right, fun's over.
Remember, Adam's full bladder driving
will be tested against the benchmark for driving impairment, alcohol.
Legally we can't actually have anybody driving
while fully intoxicated.
What we can do, however,
is bring Adam right up to the limit,
just under it and have him drive then,
with the supervision of law enforcement here.
And they're going to be using a breathalyzer on him.
We'll know exactly where he's at,
make sure we don't actually break the law.
With California law allowing a .08 alcohol reading,
Almost there.
Adam's ripe.
.75. I think that's actually our butter zone.
I have never driven anything as altered as I am now.
I can't believe the legal limit
honestly is as high as it purportedly is.
And to be on the safe side,
the police tag along.
OK, Adam, are you ready?
I'm ready, sir.
3, 2, 1 go.
But in the first slow straight away,
the officer might be reconsidering.
That's gonna be a dog leg left turn.
I hit a cone.
OK, here comes the first dog leg.
Because like the bladder test,
I hit a cone.
it's clear that Adam's driving is impaired.
Left turn, into three loop to loops.
Did I hit another cone?
That's two.
But how does his almost illegally boozed up brain
That was bad.
compared to the tolerated distraction...
That's accident avoidance. Here we go.
of a busting bladder.
You made that one all right,
but just barely.
Now back home again.
Well, once Adam is done,
it's almost time to find out.
Hi, Jamie!
Hi, Adam.
How did I do on that one?
Not so good.
Really?
Yeah.
Oh, shoot.
I kept on talking and losing focus.
I'm not surprised.
I have to see what Jamie's numbers say for the final analysis.
I am not necessarily in a position to make a judgment,
but I have to tell you,
I was far less capable of driving intoxicated
than when I had a full bladder.
I was in pain with the full bladder,
but intoxicated,
I just didn't have the ability to focus on several things at once.
And with a possible 100 points per test,
the results are.
Driving with a full bladder
gave you a score of 70 points.
Oh, that's not bad.
Driving while intoxicated
gave you 25 points.
So the myth that driving with a full bladder
is just as bad as driving while intoxicated is?
Busted.
Great.
Let's get out of here.
I'm driving.
OK, good. I'm happy about that.
Yep, the numbers don't lie.
Driving drunk is far worse.
But full bladder driving is a serious road risk.
So here's the news,
if you need to pee, pull over!
I love you, thank you for driving!
I am!
Have you had enough?
Of course you haven't.
