I remember using old brass or copper pipe to make itchy ball (gum ball) and acorn cannons, flattened and folded one end, punched a hole with a nail that a firecracker would slide down into and load like a cannon. Would set up in the woods like Viet Cong ambushing any of the neighborhood guys that would come by. Today we would be arrested and prosecuted for assault with a deadly weapon or attempted murder and expelled from school and the major discussion on the local radio and tv stations :-/
