winter 2006. I hollowed out a push pop and stuck a fairly powerful spring from a shock absorber in a heavy RC truck.put a small nail through the top so that the clip-thing from the cover rested on it.A gentle push on the clip released the cover's "safety" and shot it 20 feet.
Tools: 2$ pocket knife
materials:push pop,small wide head nail,spring
all my other projects I never finished due to lack of tools,lack of materials,or the project being massive overly ambitious.Now that I posted this I at least feel like I contributed. sorta
