Couple of thoughts on this.

It's videos like this that give the gun control morons a podium. It is the misuse of products like tannerite that get people hurt/killed (which it has) and then forces the hand of the BATFE to ban it from public access. That tool FPS Russia posted a video where he shot a car at fairly close range packed with explosive compound and almost got himself taken out by a car door. It's only a matter of time before tannerite becomes regulated and removed off of shelves, all thanks to jackasses like the one in this video.
