This is a rubberband gun that i made from left over wood from my project. It shoot about 14 feet from my gun, but u can modify the barrel for more distance and power.
Step 1: Materials
14 inches of half a inch diameter wood (can get at Pearl Paint)
A Plastic Clothspin(a wooden is fine but i prefer plastic ones for easier trigger
Step 2: Cutting and the Taping for the Handle
Two 2 1/2 inches of wood
One 4 1/2 inches of wood or more to your desire of length and power put a small v on it so the rubber band doesn't slip off on the tip
Get the 4 inches of wood and tape the plastic clothspin to it with the clip part higher than the tip of the handle. Tape the part where you squeeze for it to open to it and the mouth part below it in the gap. (check the pictures you'll understand)
