So, the next time you see a LEGO bin at a garage sale, don't look for the instruction manuals. Look for the loose Technic pins, the worn axles, and the dried-out rubber bands. Someone else's trash is your ammunition. Now go build something that snaps back.

High-end LEGO rubber band guns use a gravity-fed clip built from modified bricks (sanding down inner studs to allow smooth sliding). Builders load a stack of 20 rubber bands into a vertical tower. A sliding breech—powered by a second, weaker rubber band—pushes the top band off the stack and into the jaws of the main firing bolt. lego rubber band guns

It is the ultimate expression of childhood rebellion—taking the most wholesome toy on Earth and turning it into a launcher of office supplies.
