All you have to do is take a empty CO2 cartriage. The small ones from like BB guns or cheap paintball guns. Then get black powder (Can be found in the middle of model rocket charges or at a gun store) and grind it up to where it is very fine. Then put the black powder into the cartriage(widen the top hole if you need 2) and then put a fuse(wick) in the top.
Light it then all you do is run. LOUD and HIGHLY EXPLOSIVE.
