Shelby has a nice blog entry on the 4th of July, which in part talks about fireworks. It reminded me of some adventures:
When I was young, perhaps 16 or so, a friend of mine and I went out in the backyard with some Roman Candles, stood back to back, took ten paces, and commenced to shoot rockets at one another. In retrospect, fairly dumb (my mom thought so) but at the time, great gobs of fun.
Later, living in Japan, I went to a festival where small boats we launched to memorialize those who had passed away. The boats were loaded with rockets and somesuch, which would occasionally launch into the crowd. It seems less fun then....
