Awesome Video Lets You See an Explosion Shockwave [Video]
Okay, this is freaking bad ass. You see a lot of explosion videos, and even a lot of cool slo-mo explosion videos, but this is the first one I've seen where you can actually SEE the shockwave distorting the air as it travels!
Some crazy British guys used some PE4, which is a British military high explosive, so don't go trying this at home. Ever.
