Yeah, if i think of the things i used to do as a teen i know i would never get away with it nowadays. I didn't used to have access to dry ice so i used to take 2 liter bottles and put old bike tire valve stems in them then pressurize them to about 100 PSI (our poor pump wouldn't go over that) and them split them with an axe, even my parents used to think it was one of the coolest things ever as it has such an amazing report. Used to do this at random times in the summer and LOTS by the 4th of July and never once had anybody complain.
Then there were the spud guns i used to make and bolas and Atlatls and all kinds of stuff with my free time after school. I even had a chance to take the spud gun to school for physics class and everyone had a grand time, just a couple years later after columbine i would of been interrogated and forced into counseling if anyone on the school staff found i had such things at home.
