The right side of my semi-accurate particle thrower that I built for my proton pack. The body is made out of craft foam covered in painted cereal boxes, and the handles are pvc pipes. It's not the sturdiest thrower in the world, but I think it turned out alright. Here you can also see the heat sink I made from strips of cereal boxes, and some of the knobs, lights, and switches I got from Radio Shack.
