NSA isn't going to be behind that guy doorstep thats for sure as he was using the faulty version of the cookbook where critical errors were added so the user of those "recipes" usually injure themselves more than anybody else. Although it was hilarious how they basicly had the basic materials how to make real blackpowder and real napalm and real smoke/stink bombs that could potentially be dangerous but luckily they weren't blessed with any sort of intellectual prowess.
Although after watching that, i recommend watching Q as he has more fun/usefull method of using those matchstick heads.
