it uses a clothes pin with the fulcrum enlarged with a dowel so the handles have more movement when flinging bbs, a rubber band strengthens the spring power, and the thing is held open with 1/2" cpvc that snaps off on impact.
and of course I made a prototype yes it's crude, ugly yeah, hideous maybe, but its still a piece of crap






it needs improvement of course

the clicking is my brother playing halo, you can't see the launched bbs very well but you can see how they scatted when i go to clean up with the camera still on.
