Can you still get Bangsite at the safe and insane stands? When I was a kid we would poke a hole in the bottom of a coffee can to shove a fire cracker in for a fuse. A little bangsite, a little water, put the lid on, turn it upside down, swirl once or twice, lite the fuse and get out of the way. We could blast the can almost 2 telephone poles high with a massive report. Cheap thrills. We would get about 30 blasts out of one tube.
