Hrhrhr. I did pipe-bombs with it with which I've torn down brick walls of abandoned buildings which where already rotten. Water bombs also, with electrical ignition via very thin wires and flashbulbs. I don't get the 'without killing yourself' though. Black powder isn't like the potassium chlorate you have when messing around with fertilizer. You can grind every constituent of it all day like you want. And then mix the grinds together. Maybe avoid static electricity. But that's what cotton clothing is for, isn't it?
