a few days ago i made a rocket out of an empty shotgun shell, gunpowder, wadding from the shell, and pvc pipe. it flew way high and way far it shot flames and was epic. i stuck the pvc in the ground drilled a hole in it took the shotgun shell put the gunpowder in it, then drilled a hole in tah wad and stuck a wick in, put the wad (with the wick in it) in the shotgun shell put it in the pvc and stuck the wick out the hole in the pvc the lit it and ran. it burnt to the powder and... BOOM!!!!!!!! it shot off and went high and far, when i finally found the shell it was smoldering in the wet grass. don't ty this at home kids. "only you can prevent forest fires."-Smokey Bear
