It is always good to have a mitigating factor around, when you are learning. Parents, teachers, dad's, the like. We all do dumb things.
My dumbest has got to be Fire Football. My brother and I took a soccer ball, and cut a slit in it. We then filled it a quarter way full with gas, and lit it. Of course since the slit was so small it didn't just burn out of control.
But every time he and I would kick the ball, a spout of flame like Mad Max Fury Road would erupt.
