Next up, we've got a real cracker.
Now, is it casual Friday?
What's going on here?
Oh, wait a minute. Yellow tracksuit sword.
We're doing kill Bill myths.
Fans can't get enough of our martial arts myths.
And in fact, since the Ninja special, we've been inundated with requests to do the coffin
punch scene from kill Bill.
Oh, that's the scene where she's buried alive, and she punches her way through the
casket, climbs through six feet of dirt with her bare hands.
Right. No sword. Right.
There's no sword. Okay, put the sword down.
Yeah. Don't hurt yourself.
It's a chilling scene that nightmares are made of as our yellow suited heroine
literally gets buried alive.
Trapped six feet under escape.
Seems impossible.
Unless, of course, you are a trained martial arts assassin.
So, undeterred by being interred, our heroine uses a series of three inch power
punches, cracks the casket, worms through the soil, and lives to take her revenge.
But is such a death defying deed really doable, huh?
All right, you guys, how do you want to test this one?
Well, I think the biggest issue is going to be the fact that she didn't have a lot of
room to punch. You only had about three inches.
So we have to see how much force you can generate from just a three inch punch.
Then I think we should get a real coffin and see how much force it takes to break through
that. All right, well, assuming we can punch the lid, then we need to find out if you can
dig through six feet of dirt with your bare hands.
Before you even get to that.
How are we going to test force?
Last time we test the force of a punch, we must broke Tori's hand.
Yeah, okay.
Well, I got a brand new technique.
I guarantee you, no one is going to get hurt.
Last time they tested punching power, Grant's invention busted more fists than myths.
So this time he's gone high tech.
We've got a tech scan, flexible sensor, plugs into a USB evolution handle and that goes
into my computer.
The computer will be able to record the exact amount of force applied to the sensor.
Once the sensor records the punch.
The computer then converts the blow to pounds, giving a total amount of force
applied. So, armed with Grant's weapon of choice.
You ready for the Fury?
It's time to test what power of a punch the guys can pack.
Our very own Italian Stallion shapes up first with a full arm jab.
Go!
Nice. Ooh!
Look at that. Okay.
Stand by.
And Grant's reader records the result.
Okay, so it looks like you peaked.
There was £1,430.
Ooh.
But of course, in the movie, the heroine only had three inches of punch power to bust
through the box. So Grant resets and Tory refocuses, this time from three inches.
Did it register? It did register £781 peak.
What? Are you serious?
With Tory down for the count.
The others see if they can do any better.
But punching prowess is notably absent.
Boom boom. Belleci, £785.
Knuckles Byron, 362 and Iron Man Imahara, 612.
You know, that's not a lot of power.
But you know what? We're not trained martial artists.
And in the movie she was.
So why don't we find a real martial artist?
See if he does any better than we did.
Let's go. All right.
With our trio unable to punch their way out of a paper bag, they head off to meet a real
punching pro.
Mixed martial arts maestro Jon Fitch.
How often do you get to meet an actual professional MMA fighter?
But we get a chance to actually work with him and measure how much strength he has in
his punch. I mean, this is like a dream come true.
But does Fitch the Fist have what it takes to tackle this coffin punching myth?
Well, here's one way to find out.
In this corner, weighing in at £170, John Fitch in this corner,
weighing in at £175 from the mean streets of Monterrey, California.
Corey boom boom Blakey, let's get it on.
Mom.
In fact, any members of the family may want to avert their eyes.
Yelena? Yep.
In less than one minute.
Boom boom boom.
That's it.
Good night. Meaning fishes the fighter thereafter.
So now it's time to crunch the numbers.
We brought our whole measurement system, and we're going to measure his punch force.
I'll take his actual fighting glove and calibrate that with our punching bag and see
exactly how hard he can punch.
Ready? Set.
Go!
With a round arm.
Right. John Fitch fetches a healthy result.
Okay, so your peak punch force was £7,144.
Holy crap.
Not too bad.
Well, it is five times harder than Boom-boom's best blow.
But the real test has to be at three inches while lying down.
So this is our makeshift casket.
You're going to lay down on your back and punch up at the sensor.
The fist assumes the position, cramped as though in a casket.
It's this punch that's key to this myth.
So what's the verdict?
So check this out.
Your force on your back at coffin height, £1,482.
So a trained fighter can three inch punch with £1,500 of force.
So now the boys need to bury themselves in this mist.
And that's where Carrie comes in.
I'm going to make it as realistic as possible.
So I'm going to use all the same materials.
I'm going to make it all the same size, and then we can see for ourselves if we can punch
through a real casket.
It's three quarter inch pine made to funeral and movie specifications, and comes with a
see through side for testing purposes.
Then there's the gravesite.
That's Tory's contribution.
So I've come up with the design to test this safely.
What I'm going to do is build a box that will hold the six feet of dirt.
And then what I'm going to do is raise that up off the ground four feet with steel legs.
And then what I'm going to do is put the casket underneath that box.
Once I have the casket in, we have the dirt in place and we can start testing whether or
not it's possible to break through the casket and dig through six feet of dirt.
More on that later, because right now it's on to the punch itself.
With John Fitch unavailable, that's down to Grant and no prizes for guessing his design.
That's right.
I'm going to build a robot.
Using the robot will match it to John Fitch's punching strength, and then try and
punch through the coffin lid.
And thanks to the wonder of editing, it's a case of no sooner said than done.
Voila! A robotic punching machine that can give the coffin a fearful coffin.
I call it the Robo Fist.
Here's how it works.
First, air comes into the regulator, gets regulated to whatever pressure I want, gets
stored in an air tank.
The air tank goes to a high flow valve that lets air go really fast, that gets split into
two tubes that go down to the bottom of the piston.
Now, when those fire, these two valves allow air to come out very quickly.
It goes very fast.
Three, two one.
I think it's working.
And that means Robo Fist is ready for a test.
And I'm just going to dial up the pressure until the robot can punch as hard as John
Fitch.
Remember, even with a tiny three inch punch, John Fitch managed a whopping £1,300 wallop.
Grant's going to have to match that exactly.
