You mean like the principal of your school discovering you have the Army FM "Improvised Explosives and Munitions" in your locker?
Look, not my fault, my dad strong armed me into model rocketry. First thing he does when the stuff comes is duct tape a spent motor case to a live motor, fill spent case with FFg then launch from 15ft fiberglass antenna mast. Then it was on to duct tape largest motor to old broadhead arrow, lay in angle iron, watch disappear. The lessons on acetylene trashbags, magnesium and potassium chlorate, etc.
Was it any wonder that I was that kid?
