But bullets are only one of the things you see.

Tony Stark survived in the suit.

You also see explosions constantly going off right next to him, and he is relatively unaffected.

For the question is, can our Iron Man suit protect the wearer from an explosion?

First, inform us.

I think it's important to go into what kills you in an explosion.

The first thing that kills you is the shrapnel and the fire.

But if you survive, both of those things can still be harmed or killed by the blast pressure wave.

That is, as the explosive is expanding.

It creates a front off air, moving at an incredibly high speed.

And when this pressure wave goes through your body, it moves every Adam of her body a few microns at well past the speed of sound and turns the inside of you to jelly.

It's awful.

So how do we test whether our armor can protect aware from that?

That's why I'm standing on the bomb range in Alameda County right now.

This is a burst disk.

It's made by a company called Sicko.

And these burst discs have been calibrated to burst it.

Anything over £75 per square inch of pressure.

And that is an amount that we have calculated as a pressure that would definitely kill you if you received it near an explosion.

We're going to place the burst disks at six feet, 12 feet, 18 feet and 24 feet from the explosion to test the impact of the blast.

Three.

Yeah.

One.

Awesome.

I wanted one or more burst disk to break, but not all four.

I'm gonna predict we got what I'm hoping for.

Oh, shoot.

Wait a second.

What?

Well, it looks like it looks like all four burst disks are intact.

That tells me that we need to be even closer to this blast.

For is really close.

Builder Jentzsch actor and I will place the burst disks at three feet four feet and five feet from the explosion.

The farthest disk that ruptures will determine our death zone.

Then we'll repeat the explosion with the Iron Man armor in that death.

So now that we have used our burst disks to determine the perfect death zone.

The distance at which the blast pressure wave would kill you.

It's time to put our Iron Man armor in harm's way.

And to do this we're using now four burst fists and we're going to place two of them inside the armor and two of them outside the army.

Let's go three feet.

Perfect.

Awesome.

And after we detonate, what we're looking for is any difference in behavior from the ones that were inside to the ones that were outside.

After all the time and effort that went into building this suit.

I can't believe we're about to do this.

30.

Come on, man.

One, uh, wow.

Standing his head still on and his body is still there.

That was a really good son.

Excellent.

We're all clear.

All right, well, look on first pass.

The suit itself survived the explosion.

Admirably.

Helmet did Gray.

We lost one of his both years.

His radio way over here.

No wonder he can't hear.

Let's pull the chest off.

Oh, what is it?

These two burst disks outside the armor fully burst all the way through, as we would totally expect, but the inside one is unmarked so clearly the armor rendered a lethal explosion survivable.

I just say when we started down the path of this project, I had no idea how elaborate it would get.

And I really did not expect this material.

The three D printed titanium to perform so well be so Brazilian, and to have these incredible material properties that it is continually demonstrated.
