As a kid (a pre teen) what kind of things did you modify/make into a "weapon?" Things like rubber band slingshots or twig bow and arrows? Actual kid ingenuity. For example, (I dont know if they still let kids have them) toys used to come with spring loaded "missle launchers" Transformers in particular had these. We used to take them appart and "boost" them by putting in much stronger springs. You could increase the range from about 5 feet to well over 20. For another one, I notched a 2X4 to accept a throwing dart. With a length of "rehab" rubber (the kind people use to stretch in rehab) I could fling a dart over 100 yards. My favorite though was my "air rocket." I had a music stand (the kind that held up a drum) it was little more than a tripod with a hollow metal tube in the middle, about 2 feet long. I had a foot pump to blow up rafts with. The air pump tube fit (and sealed) in the music stand. If you took a leap on that foot pump, whatever you had put in the tube would come out with great force. I had some ball bearings that I could put through corrugated tin. It really was a crew served weapon though if you wanted to "aim" it. So, what did you do?
