Please, don't try anything you're about to see at home.
We're what you call experts.
On this episode of Mythbusters:
I'm gonna have to warn my mom before she watch this episode.
Adam and Jamie face off in an epic battle of fire...
That is insane!
and ice.
They want to test the viral video claim
that a fire extinguisher
can protect you from a flame thrower.
I lived!
Holy @#￥%……&.
Then, in the desert,
This is so cool!
Kari, Grant and Tory go high tech...
OK, helicopter's in position, and ready for the test.
to take on a myth from the movie "Body of Lies".
I'm getting ready to be kidnapped.
Using a car induced dust cloud,
can you really cloak your movements
from high-altitude a spy drone?
Who are the "Mythbusters"?
Adam Savage,
It's scientific.
and Jamie Hyneman.
Fun for the whole family.
Between them, more than 30 years of special effects experience.
Together with Kari Byron,
I was less excited after my first kiss.
Tory Belleci,
Why are we doing this?
and Grant Imahara.
Who wants some?
They don't just tell the myths,
they put them to the test.
What's on the docket?
Something you and I know quite well,
the meeting of opposites.
You're goona have to be more specific.
Okay. Fire versus ice.
It's a viral video that's been going around
one armed with a flame thrower,
the other armed with a fire extinguisher.
They both fire their devices
and fire and ice meet in the middle.
And apparently, according to the clip,
cancel each other out.
Dibs on the flame thrower.
Don't you want to hear more about the story?
No.
All right then.
Roll the clip.
What do you get when you cross an internet viral video
and an elemental duel?
An epic clash of fire and ice.
But can you actually beat back a flame thrower attack
with a plume of CO2 from a fire extinguisher?
The team want to know if these striking images
are film fakery or fiery fact.
So, where do you want to begin?
Oh, let's say we set up a small scale
as a proof of concept.
I mean, I can throw together
a little flame thrower in minutes.
But, as I'm thinking about it, you know,
they show a normal CO2 fire extinguisher in that clip.
And I'm not so sure they fire that far.
Easy enough to figure out.
We've got one down stairs.
Let's just throw up a gauge and see how far it propels.
Okey.
So, before the guys throw down small scale flames...
Well, let's scale it up.
they're going to check
that a standard 15-pound fire extinguisher,
like the one in the clip,
can even go the required distance.
So, 25 times 6 is 150.
60 feet between these guys,
which means each of these things
has to shoot 30 feet
in order to meet in the middle, at least.
Yeah, at least.
That's the mark to match.
But first here's Professor Savage
for "Firefighting 101".
Here's what you don't understand.
There is nothing special about these.
These are your standard issue run of the mill
what we call 15-pound CO2 fire extinguishers.
CO2 means carbon dioxide.
And that's what they are filled with.
And when pull the pin and squeeze the lever,
that CO2 comes out of the nozzle at the bottom of this cone,
and it flashes to a gas.
That CO2 gas comes out in a big smoky billow,
creating a nonoxygenated environment
where fire can't burn.
The question we are concerned with
is will it actually fire out 30 feet?
Honestly, I don't think so.
But that's why we are doing this test.
Three, two, one.
I think that's pretty far.
The target to get the myth over the first hurdle
was around 30 feet.
And after studying the high speed footage,
Adam's happy.
I'd say that the unmodified fire extinguisher
fired its gaseous billow 25 feet,
which is shockingly close to the clip.
I think it's time to put it up
against Jamie's impromptu flame thrower.
Impromptu and top secret.
Even though we tell people
not to do what we do at home,
when it comes to home made flame throwers,
I'm just not gonna show you how to do it.
With the curtain closed
on the flame thrower puppet show,
it's on to a proof of concept test.
And they won't be shooting it in the shop.
Obviously, we can't be squirting
lit gasoline around inside in shop.
So, we've come to the San Francisco Fire Department
Treasure Island Training Facility.
I'm ready to do battle with the Hyneman.
And we're goona to do it here.
But do what exactly?
The whole point of this exercise is to see
if my fire extinguisher can have any appreciable effect
on Jamie's flame thrower.
And to do it, he'll be wearing the full fire-proof suit,
or what he likes to call, his dancing suit.
How do you want to do this thing?
Well, for safety's sake,
why don't I stay put with my stream of fire
and you kinda walk into it with the extinguisher.
I like that better than the alternative.
- Let's do it. - Okay.
So, in small scale,
Adam and Jamie are looking to
explore the concept of the myth.
All right, fire extinguisher versus flame thrower, small scale.
Is it possible...
I'm ready.
that a standard work place CO2 fire extinguisher
like the one in the viral video...
Let's light her up.
can snuff out an airborne jet of flaming gasoline?
Next up, Tory, Grant and Kari
kick up a dust storm for a kidnapping.
All right, guys, what do we got?
This one involves fast cars,
dust storms and spy drones.
Are we testing the myth from the movie "Body of Lies"?
Yes. And this is the one
where Leonardo Dicaprio is getting kidnapped,
but he's being monitored by a spy drone.
Now, to fool the drone, his kidnappers show up in cars,
drive in a circle, create a dust storm
effectively blinding it.
This would be awesome to test.
It's a classic scene from the silver screen.
In the movie "Body of Lies",
a band of highly organized SUV driving bad guys
kidnap our hero by cleverly cloaking their movements
from a high altitude spy drone with a dust cloud.
But can a manufactured-by-motor dust storm
really blind state-of-the-art military technology?
Now, my gut feeling is, this could possibly work.
I mean, have you ever driven on a dusty road
behind somebody?
The car in front of you disappears.
Yeah, but that's when you're enveloped in dust.
This myth is about someone
observing from above the dust cloud.
I think the good news is, we don't need a spy drone.
I think we can get the same kind of camera
and mount it onto something else in there,
like a helicopter.
All right, well it sounds like all we need now
is a dusty location,
some SUVs and a target to kidnap.
Oh, one more thing, you're totally blind
when you are driving in a dust storm.
So, maybe we need to come up with
some sort of a system for driving in a circle
without actually being able to see.
Yeah. I guess driving blind could be disastrous.
Correct.
By the time the team takes this test to the desert,
they'll require the military like precision and planning
to safely carry out the dangerous driving
So, it's a trip to the emergency vehicle operation's course...
Let's have some fun.
where Grant and Tory will test
the safty precautions necessary
to pull off the sand-eye-blind driving the myth requires.
It's gonnal require laser sharp concentration.
Sorry @#￥%……&.
Oh, no, @#￥%……&!
Grant didn't get the laser sharp concentration memo.
We haven't even started,
and it's a lot more dangerous than we thought.
Now, since what we are doing is creating a dust storm,
which means limited visibility.
And since we don't want to crash into each other,
we are instituting a number of safety procedures.
Every car will be outfitted with this strobe light.
It's got a portable rumble strip in the form of this chain.
Lay this out along the perimeter,
and that will tell us when we are on path.
And we'll gonna take these delineators
and create a giant circle that the cars can follow,
and we're gonna have a slapstick on the front of the car,
so when the car passes by, it hits it,
letting the driver know that he's still on track.
It's kind of like a giant "Wheel of Fortune."
And because we don't have our own dust storm,
we are going to create our own dust storm with opaque paper.
Ready for a dust storm?
Bye-bye.
What could possibly go wrong?
With the paper supposedly simulating
the visibility of a dust storm...
I'm ready.
and one fender-bender already under their belt,
the team starts slow and careful.
All right.
Let's start at five miles an hour
and move up to ten miles an hour.
In three, two, one, drive.
With just two drivers and not the full set of four,
the question is, can they drive nearly blind...
Start braking.
and in a tight circle safely.
You're way off course, stop.
The answer would appear to be...
no, no, they can't.
Where the hell am I?
Next, Jamie super sizes his sizzler...
It's 100% illegal.
while Adam pumps up the gas.
This viral video suggests that
if a mean-looking dude is going to
fire a flame thrower at you,
you can hold back the flames with a fire extinguisher.
Apparently, the cloud of CO2 will balance out
the burning gasoline by meeting it in the middle.
I'm ready.
First up though...
Okay, bring it in.
Adam and Jamie want to know how to go
with a more modest-sized flame thrower.
That worked.
It certainly put out Jamie's fire,
but it wasn't an unqualified success.
It seems my effective distance
is really about this distance,
not like the full 20 feet.
Yeah, it's interesting, it seems that there has to be
absolutely complete coverage of the CO2,
or it's gonna continue to burn.
Something the thermal imaging camera backs up.
The cold jet of CO2
only becomes truly effective at close range.
That's a problem,
because the myth would have us believe
it can hold back a full-sized flame thrower 25 feet away.
And a close look at the high speed
confirms the poor result in terms of distance.
Okay. I'm definitely pushing the flame back in here,
at just under ten feet.
I think I'm about to put it -- there it is.
I put it out.
But you had to almost be covering me
with the CO2 froth to go out, and in the clip...
They're 60 feet apart.
So I absolutely need to beef that thing up.
Yep, based on the results so far,
the team believes the standard extinguisher
used in the clip will have no chance.
And if that's the case,
Adam wants a backup, to ramp it up.
So, he'll be making a second extinguisher
with extensive modifications and using the force.
Here's what's happening,
I clearly need more power.
I'm going to start the experiment process
by measuring the 15-pound fire extinguisher,
using my pressure swingometer.
And I'm gonna be comparing that
against all my subsequent measurements
from all the modifications I'm gonna make.
It might seem that what's happening here
is the meeting of opposites--
fire, and the thing that puts out the fire.
But in fact, it's actually just about force.
The fire's pushing forward with the force,
and I need to meet that with an equal and opposite force.
I don't need a white billowy cloud went to 25 feet.
I need to push the fire back from 25 feet.
So I'm going to start by
increasing the size of my extinguisher.
I will go from 15 pounds to 50 pounds.
Then with a few modifications,
we'll see if I can get that pressure wave
extending out almost 25 feet.
Go.
While Adam looks to beef up his blast,
Jamie invites his inner pyromaniac to the party,
by making a military grade flame thrower.
My task now is to make an honest-to-goodness flame thrower.
That's gonna be the manifold.
And given that we are using high pressures, flammable fluids
and they are lit,
I need to make sure that whatever I'm using is really sturdy.
With that in mind, I'm gonna use these air tanks.
They're made for thousands of psi.
So, given that we are only gonna be
putting hundreds of psi in them,
I figure that they're gonna be plenty safe for us to use.
The air tanks will contain the fuel.
But as for the details on the rest,
well, we can't show you that.
Seriously, this thing right here
is in a league of its own.
It's 100% illegal.
We were able to do it only under the direct supervision
of a number of different governmental agencies.
And let me tell you, it was an ordeal.
So, don't even think about it.
Which gives you an idea of what Adam is up against.
And after toying with a variety
of nozzles, outlets and tubing,
he decides H2O is the way to go,
in order to tackle Jamie's super sized sizzler.
Try it out.
to the CO2 stream to try and get more force.
I want to push back this fire.
And that's where this comes in.
It's a pressurized container full of water,
and I'm gonna feed through this tube
into a nozzle on the side of this nozzle,
which very much looks like this,
water comes in here, CO2 comes out here.
Hopefully, what ends up coming out of the business end
of the cone has a lot more force behind it.
Dude!
That was great.
Adam wanted more force and he's got it.
Mixing the stream of water to the super cold CO2
results in a cloud of fire quenching ice crystals.
And the additional massive of water
adds that much more force to the equation.
I've got my flame thrower,
and Adam has his beefed up fire extinguisher.
I guess there is nothing to do now but to take them out,
put them head to head and see what happens.
Kari, Grant and Tory are taking on
a hollywood tall tale of international espionage.
Can you really use a car-induced dust storm
to fool the aerial eye of a spy drone?
And to safely recreate the dangerous driving
required in the myth...
Sorry @#￥%……&.
the team's gonna need a lot of practice.
Start braking.
You're way off course. Stop.
But after a tough frustrating day of testing
and tweaking their guidance systems,
they realized the real issue
has been right in front of their eyes all along.
I can't see bugger all.
The basic thing we misjudged
is the transparency of our paper.
We were trying to get around 10 to 15% visibility.
But we ended up with basically 0% visibility.
Right now, we can't see anything.
So we're gonna have to come back tomorrow,
and come up with a better solution
to simulate the sandstorm.
Yep, what's required is a new day, a new location,
and a plan named after the second letter of the alphabet.
And this is plan B.
We'll put this burlap on the our windshields.
And this should give us about 10% visibility,
that of a dust storm.
Confident in their new solution,
the team has stripped back
their safety systems to the bare minimum,
and upped the ante by matching the myth's four cars.
So, with Grant coordinating communications...
Three, two, one, go.
and Tory, Kari and two mythterns behind the wheel,
it looks like they have nailed the visibility issue.
Yeah, it's been good.
Because although they can just barely see,
the view, just like in a dust storm, is severely limited.
And it's only their safety systems
that are keeping them on track.
This is insane!
And that means, they can go to work...
Everybody could just speed up a little.
practicing their four-car dust-making dance.
This is working!
Let's take it to the desert.
Adam and Jamie are about to turn up the heat...
Nice day for a flame thrower.
armed and extremely dangerous.
It's my own personal kick ass version
of a military flame thrower.
They have arrived at exactly the right location.
The first rule of firing a flame thrower
in the state of California is
that you pretty much can't do it.
But if somehow you get permission to do it, like we have,
you need to do it in a place
where you're not going to set anything on fire.
That's what brings us here
to the Yolo county bomb range in northern California.
Acres of barren landscape
where we can fire our flame thrower to our heart's content.
The danger lies in the risky combination
of flammable liquids and high pressure.
And here's how it works.
I've got two tanks full of fuel.
I've got a third tank
full of inert gas at high pressure
that I will use to pressurize the fuel tanks,
such that when I pull on the lever,
all of that fuel will empty out the end of this gun,
and burn in about four seconds.
Cue pyrotechnician extraordinary, J. D. Streett,
the man tasked with overseeing the safe use
for extremely dangerous piece of equipment.
And with the tanks now filled with gasoline...
Secondary valve opening up.
Adam and Jamie...
Safety is off.
get set for the first live lit test.
You're open.
The gun is hot, the pressure on.
It's time to let rip.
First flame test.
In three, two, one.
Dude!
That worked.
That was spooky as hell.
Jamie just test-fired our home-built flame thrower,
and it worked fantastically.
I think that might be the scarest thing
that's ever been built on this show.
It's right up there.
It looked to spray a wand of hot death,
between 60 and 80 feet,
which is exactly where we wanted it to be.
The stream of burning gasoline successfully matches
the mythical clip for distance and volume.
But for the test itself,
Adam will have to stand in the line of fire, literally.
To do that, he's going to use a safehouse.
And here's one he prepared earlier.
Right here.
Before we actually conduct the full size experiment,
we need to make sure that my shield here
will actually do its job.
I need to be able to stand in the path
of this flame thrower, and not get burnt.
Are you ready?
I'm ready.
So, Jamie's going to point it right at this thing
while there is no one behind it, and fire.
And only if we determined that will safely keep me from getting burnt
are we going to use it.
Glass house flame test,
in three, two, one.
That looks like it might keep me safe.
It looks good.
All the devices are working perfectly.
The flame looks exactly like it does
in the clip that we are trying to replicate,
and the glass house seems to be holding up just fine,
so I think Adam is going to be safe.
I think that worked beautifully.
Now, what we gotta do is wait for it to get dark.
Jamie's not lying.
because to match the mythical clip
and face off with fire and ice
they need a atmospheric nighttime backdrop.
Next on "Mythbusters,"
the team decamp to a deserted dusty desert location.
You can't tell, but I'm smiling right now.
Please do not try what you're about to see at home.
We're what you call experts.
Can't you tell?
Unmanned military spy drones are state of the art,
eyes in the sky.
But is it possible to obscure
nefarious ground level activities from their cameras with a dust cloud?
To find out, the team has decamped
to a dramatic and cinematic deserted desert location.
This is beautiful!
And at first light, it's time for action.
We've come out to the Black Rock Desert in Nevada
so that we can test our "Body of Lies" myth.
Now that's that you can hide from a drone in a dust storm.
This should be the perfect location
because it's entirely gypsum dust.
So here's the set up,
we are gonna create a giant ring out here in the desert,
similar to our practice run,
Hi, let's set it up.
drive around in a circle to create our dust storm.
Kari is gonna be our target.
We're gonna be driving around her,
and create as much dust as we can.
When we get enough dust,
we are gonna put her into one of the SUVs
and then all of them are gonna go in different directions.
And I will spot from the helicopter
and try and guess which of the cars the target is in.
My feeling is, if we create enough dust,
he's not gonna be able to tell.
The circle is complete.
So the first order of business for Tory and his team of drivers
is a practice run to find out if the dust making conditions
are the same as in the movie.
Now let's if we can kick up some dust.
The drivers start off slow,
using their high visibility cones to stay on track.
They build up speed.
You can't tell but I'm smiling right now.
And the result down here at ground level at least is impressive.
I think it's gonna work.
The thick dust hanging in the air,
makes for tough driving conditions.
Holy crap.
Look how hard it is to see.
And it looks just like the mythical movie scene,
but the true test will come once Grant gets an aerial perspective.
So we're not using a spy drone in this myth,
we are using a helicopter.
We've got the same type of camera,
the same lens and we're gonna set up the same framing
for judging this dust cloud.
It's as close as you can get to flying a spy drone without
actually flying a spy drone out of a military base.
All right,
I'm ready to be the kidnap target in this dust storm.
Now unlike the movie, I'm actually going to be in this car here.
This is for my protection because, let's face it,
four cars going around in circles in a practically blind dust storm
just doesn't seem like a good place to be standing around.
And that means it's go time.
Grant "Eye in the sky" Imahara,
establishes a high altitude vantage point.
Ok, we are in position, ready to begin the test.
Just like the Movie,
lead driver Tory and his three accomplices,
surround kidnapping target Kari.
We're starting test one for our "Body of Lies" target acquisition.
And increase the speed of circling,
attempting to mask their actions from Grant with a dust cloud.
Will it work?
We're starting to get a really good dust cloud.
When the team on the ground decide
the dust cloud thickness is at its apex,
they decide to go for it.
I'm getting ready to get kidnapped.
With swift military like precision,
one of the cars pulls out of the circle and alongside Kari.
Here we go.
I've got her.
From the ground, as she jumps in,
the scene is pretty much obscured,
but was it a success?
Was Grant and his high tech drone camera fooled?
All right, did you see me?
It's hot versus cold at 60 feet
or as we used to refer to when Jamie was duelling a lot
in the olden days, ten paces.
I will be armmed with a fifteen pound standard issue
cone-tipped fire extinguisher.
And I've got four gallons of high pressure gasoline
that's gonna give me a good 60 feet.
If the clip is real,
my white CO2 plume of smoke ought to meet his fireball
somewhere in the middle.
The myth suggests a standard 15-pound fire extinguisher
could stop an attack from a flame thrower
by meeting it in midair 25 feet away
and effectively putting it out.
However, as the less than spectacular performance against
Jamie's small scale flame thrower proved,
it is unlikely Adam is going to successfully beat back the burn.
This is gonna be scary.
This's a funny thing about flame throwers,
you are not supposed to place yourself in their path,
so we've taken every precaution.
Ok, everyone set?
We're going hot.
This house is made of fireproof glass, fireproof silicone, steel,
wooden sides that will keep the fire
from wrapping around and enveloping me.
I'm also wearing a full proximity suit with a hood.
On my command of go.
Ready.
All of this should keep me perfectly safe.
Well we're about to find out.
But just in case, Adam's mom, please look away now.
Two, one, go!
I lived! Holy @#￥%……&.
That was awesome.
I don't think my fire extinguisher did very much.
But that was awesome.
Yep, that was a little too much fire
for Adam's little extinguisher.
Tonight this is something else.
Three, two, one and then...
hellfire.
You just pulled the trigger and wait for it to run out.
It seemed to me like
I was pretty much bathing Adam and his little house in fire.
I don't think my extinguisher did very much
because for most of that test,
all I could see was fire enveloping my entire little house.
And I was totally protected.
It worked just like we planned.
The safety precautions worked.
Adam successfully survived five terrifying seconds
inside a giant fireball.
But as for an actual result,
it's over to the high speed footage.
I'm not having any effect on you whatsoever.
Completely enveloped in a fireball there.
It was like a mountain of fire rolling towards you.
That is insane!
I'm gonna have to warn my mom before she watches this episode.
She's gonna think I died in there.
The clip is pretty much busted,
but remember, I suspected it might not work
which is why I built this bad boy.
It's got a 1,500 psi high capacity
ball valve water in feed
to get the most amount of pressure
and volume out of the CO2 cloud as I possibly can.
I'm ready, Hyneman!
In the test in the shop,
I was able to have a significant amount of back pressure
at 25 feet.
That really ought to allow me
to push Jamie's fire ball back to where it belongs,
away from my little house here.
Meeting Jamie's flame in the middle may be a tough ask.
I'm ready!
But can Adam's modified monster
I'm ready!
even improve his chances of survival?
Three, two, one.
This is so cool.
We have our own helicopter.
We got these vehicles.
We're tearing up and down the desert creating dust clouds,
trying to hide Kari from
the cameras in the sky.
I mean I feel like a big kid
playing in a sandbox with all these toys.
But with the dust settling on test one,
did Tory and his toys manage to kidnap Kari successfully?
All right, did you see me?
Did Grant spot which vehicle Kari was smuggled into?
It's the car that went toward our camp.
You got me!
Grant had it covered.
In the key area, the center of the circle above Kari,
the dust cloud just wasn't thick enough to
deceive the pin sharp resolution of the military-grade camera.
Now if you look at the amount of dust being created by these SUVs,
it looks like a lot.
But from the air, it's a totally different story.
It looks like a ring of dust
and in the middle is Kari's car
which is still perfectly visible.
So if Tory and Kari are gonna get away with the kidnap,
they're gonna have to come up with a different technique.
All right, we're making those donuts,
Grant's having no problem seeing us.
Yeah we're not kicking up the dust that you see in the movie.
But one thing I happen noticing
is when we're flying across the desert at a high speed,
we are kicking up so much dust.
So maybe we set up the cars
and we just fly by them at high speeds
and hopefully we create a dust cloud thick enough
that we hide you from Grant.
With the donut technique busted,
Tory and Kari have another plan they hope
will put this myth back on a straight and narrow,
a plan based on the theory that a high speed fly by
creates more dust that circling the target at moderate speeds.
Ok, helicopter's in position
and ready for the test.
This is the new dust cloud plan.
We have the target car which I will be waiting in.
We're going to have two kidnap vehicles pull alongside of it.
Here comes the two kidnappers.
Then we have Tory and another dustmaker car
zooming by as fast as they can
creating a huge dust cloud.
Here comes the dust cloud makers.
One dust car, two dust cars.
Then Grant has to guess what vehicle I am in.
And what do you know?
I can't see anything!
I cannot see anything.
By driving past upwind at high speed,
a thick cloud of dust perfectly obscures
the scene of the kidnapping crime.
Ok, they're all driving off.
I don't know.
I'm not sure.
And Grant doesn't have a clue which car Kari is in.
We did it! Yeah!
Ok, so the dust cloud that we were able to create
actually made a canopy so that Grant could not find me.
Dude, I thought that was totally gonna be busted,
but it turns out you beat the video camera.
Yeah, we beat the video camera.
You know, that's what they had in the movie,
but we know the drones also have thermal cameras.
And they would easily been able to switch over to thermal camera
and see the heat signature.
I say we set this up again with flare camera
and see if we can hide the person with the dust cloud.
All right, I'm ready for another shot.
Let's see if we can fool you this time.
Coming up on "Mythbusters",
What does it take to beat a thermal imaging camera?
So far the myth that you can hide from a spy drone's video camera
by creating a dust cloud is kind of a mixed bag.
See on the one hand,
if you use the ring method like they do in the movie,
that doesn't work at all.
All right, did you see me?
It's the car that went towards our camp.
But if you use the method that we came up with,
which is the high speed fly-by,
that does works.
And it is able to visually obscure you from the camera.
I can't see anything!
I cannot see anything.
We're not done yet,
because it turns out these spy drones
are equipped with another type of technology,
forward-looking infrared cameras.
These pick up heat signatures.
It should have no problem picking out a warm body
even if it's obscured by a dust cloud.
There's nowhere to hide now.
Grant's right to be confident,
unmanned drones are regularly used on search and rescue missions,
and they're duly equipped with state-of-the-art camera technology,
including thermal imaging,
to find and locate human heat signatures.
And that means to beat Grant,
Okay, helicopter is in position and ready to go.
Kari and Tory will really have to get their spy on.
Because on this test,
Grant's using a full range of technology at his disposal.
Here come the dust makers.
There's the cloud.
As before, the high speed fly-by cloud
obscures the regular video camera.
Get in there.
Oh yeah!
I see her.
I've got your number, Kari.
But the heat signature from the scurrying bodies is as bright as,
as bright as their body temperature.
you're in the car on the right.
It was really a game changer,
where as they were obscured visually with the dust,
with the flare camera,
I can see right through that.
I could see like little white dots walking between vehicles,
so that made it really easy to pick out where Kari went.
All right, you could run from the thermal imaging camera,
but you can't hide.
Apparently.
But you know what, I'm inspired.
We fooled you with dust,
I think we can actually cloak ourselves from that camera as well.
I think the challenge is on,
and you're going down, sucker.
All right, let's see!
And to take down spy master Imahara,
team kidnap heads back to the shop for a camouflage conversation.
So we need to find out if it's even possible to beat the infrared camera.
So, we're gonna send it into the sky,
just as if it was the drone,
and see if we can come up with the technique to get by it undetected.
Psychedelic.
Now, Kari and Tory do have some info to go on.
After all, they previously been successful at beating an
infrared motion camera with a glass screen.
Using that knowledge, they've got a head start,
but these are different circumstances.
All right, glass works, but
Look at that.
you need a huge piece.
It's just gonna be too heavy, too cumbersome and too dangerous.
Yeah, it's far from practical,
so they play with a few similar ideas.
Before Kari comes up with an even "cooler" idea.
That makes a huge cloud above you.
You can't see anything. The whole thing turns black.
But will a cold blast of CO2
work well enough to fool eagle-eyed Imahara's thermal camera?
Well, let's find out.
It's the final showdown.
Ok. We are good to go, good to go in the helicopter.
The set-up is the same as before.
Ok. Kidnap vehicles, move in.
The kidnap team is going to
create a dust cloud to block the standard video camera.
Okay, Here they go.
But this time, in addition,
the team adds a little cool CO2 to the mix.
What the heck is that?
That is two clouds of thermal camera obscuring CO2.
I can't tell anything!
And Kari is whisked away unseen by the bad guys.
That was pretty cool.
Now see, I thought I had them with the thermal imaging camera.
When the CO2 goes off it's like this-
this blue and black cloud and
you can't see anything behind it.
But remember, the original method used in the myth,
four cars circling the victim,
didn't quite pan out as well as the "Mythbuster"s' efforts.
So we busted this myth
but just the technique used in the Hollywood movie.
It's the car that went towards our camp.
We took those same elements,
moving vehicles in the dusty desert,
Here comes the dust cloud makers.
and created a cloud so thick,
we're able to obscure the high-tech cameras and kidnap Kari.
But the most interesting part of this for me
was actually we got to figured out
how to get past the thermal camera.
I can't tell anything!
Getting to go back to the shop and come up with our own method
and have it be better than the movies,
that was awesome.
Well the technique used in the movie is busted.
But you can beat a video camera with a dust cloud
and you can beat a thermal imaging camera with CO2.
So it's possible.
I just think Hollywood needs to give us a call
before they write their spy movies.
Hollywood, hear that? [Call us]
Adam is about to face off against Jamie's super-sized sizzler
with his beefed up extinguisher.
I am ready!
I'm ready.
This is it.
Even with a souped up super extinguisher,
can Adam hold off Jamie and survive?
Three, two, one. Go!
It's difficult to tell during the chaos.
But for a moment, Adam's powerful blast of ice crystals
does seem to push back the tide of flames.
I think I got him.
Adam clearly thinks so.
But to see for sure, it's over to the super slow-mo.
This time Adam is actually making an impression.
He may not have matched the mythical clip
and met the flames in the middle.
Oh, look at that!
Oh, that's beautiful.
But he's certainly holding them off
and preventing them from engulfing the safehouse.
It almost reached you.
It wasn't exactly like it was in the clip.
No. Oh man, look at that.
I'm totally beating back the fire.
It's not, definitely not meeting in the middle,
but I am successfully pushing back your flame thrower.
You're-you're just sneaking through by a hair,
but you're holding me off.
That is incredible.
I feel really good.
Jamie has spent literally weeks obsessed with this flame thrower
and I have run my fire extinguisher and various iterations
through like probably 20 to 30 separate tests in the shop.
And it all came down
to my 50-pounder actually pushing back
Jamie's Fire ball.
The first try was no competition.
That flame just completely enveloped the extinguisher,
the house it was inside and everything.
It was no contest.
The second time was a little different.
He actually held me off.
How do you want to call it?
Unfortunately we got to say it's busted.
I mean the 15-pound fire extinguisher was
absolutely no match at all for your flame thrower.
Even the heavy duty one that you put together
just barely held me off.
But it didn't look anything like the clip.
This one's totally busted.
Busted, but awesome!
