Reminds me of the old roman candle wars. Those old candles held twenty balls if you got the big ones and had a real tendency to blow the last three or four out of the bottom of the candle. I hated that dad wouldn't let us have roman candle wars. Years later it was bottle rocket wars. Me and the neighbor two doors down on the other side of the street would buy many gross apiece of the little bottle rockets and throw them at each other in fun. The neighbor in between had no sense of humor!
