When I compare what I and my mates did in the early '60's when we were pre or young teens with what my son does, or at least what I know about what he does, it's amazing my generation survived.<br /><br />Probably the stupidest thing we used to do was have fights with those old Daisy lever action BB guns. Only rule was no aiming at the head. Given the lousy accuracy they had it didn't make much difference. My kid doesn't even know how to make a shanghai, but we all had one most of the time.<br /><br />At night we occasionally went along the outside of the old passenger trains that had runnning boards along them. Pull up beside a window and tap on it and make a fierce face and frighten some aged citizen half to death. We were doing our own form of train surfing before the term was invented.<br /><br />Made an alley (marble) gun once out of a metal bike pump. Got a bit of thin wire and pulled the wick of a penny bunger (cracker - firework) or thereabouts back up the tube with the wick sticking out the hole where the valve tube went. Put an alley in it. Tamped it down with plasticine or something. Lit the wick and fired the alley. The target cat was never at risk. Lucky I didn't tamp it in with something too hard or I'd have made a pipe bomb and hurt myself, but I didn't know that then. <br /><br />What did you do?
