Michigan machinist GarE Maxton composed of over 125 pieces made from brass, bronze, copper, aluminum, magnesium and steel into puzzle sculpture is magnificently complex and the parts can be used to make two completely different objects.
Starting the disassembly process requires a special key. Once diassembled, about 20 of the pieces can be recombined to make a functioning single-shot pistol.
Not all the pieces of the cube go into making the gun, but the others aren't a waste. They're the bullets, custom tools to assemble it, a standard sight, a laser sight, a canister containing black powder pellets, a storage area, a spent primer removal tool and a ramrod.
The video is over seven minutes long, so it’s comforting to know that if someone were to try to do this on a plane, they’d probably get noticed.
