i know its not just made out of black gun powder. when i was a kid we had fireworks at my house i would take the stuff out of them and put then in plastic containers and just put a footlong wick on them and just run, and they were in like tic tac boxes that we would tape and set up. and i was just was saying how big the loudness was. I was since i am into this kind of stuff i am doing this in my college degree trying to help with the military, with making new things for them. I also asked about this was becasue of it, i am just interested into just this stuff in general.
