 And to just prove that, the guys are going to tear apart a TV.


 
All set? Let’s go.
 
We’re going to put a pound of C4 into the television, and then film the explosion on two different high-speed cameras. One will be filming at 1,000 frames per second and the other will be filming at 6,900 frames per second. We’re going to compare the two and check out the details. 
 
And after a quick muse 1 of the manual, it is time to make room for the boom.
 
Alright, demonstrating a high-speed camera by blowing up a TV. Here we go in three, two, one, fire!
 
Now in real time, basically you say three, two, one, the button’s hit, and then for us, that’s it. 
 
It’s pretty much now you see it, now you don’t.
 
Yep. Real time, it’s a blink-and-you-miss-it moment. 
 
But for the high-speed you see a lot more. This camera is running at 1,000 frames per second. I mean you can see the bloom of destruction, the glass shattering, the plastic flying. 
 
But now check out the detail you can see with the 6,900 frames per second. You can actually see the shock wave moving out from the center. You can see the television pulling apart as it starts to explode. Not only that, but you can see the gases expanding, and then rushing back in to fill the void where they’ve just left. This is a much more detailed 2 complete story of explosions. 
 
Ain’t that the truth? It’s the high speed that really gives that detonation 3 detail and in full high-definition. 
 
Coming up on “Mythbusters”, the A to Z of boom. Fire in the hole! Oh, it’s so beautiful.
