Got a few Nerf guns laying around, perhaps a toy chainsaw here and there Us too. You could gut them, put a bunch of LEDs inside, install sound effects, a quick paint job, and there you have it, your very own Gears of War Lancer. The chain on the chainsaw actually moves, the lights actually light up, and it shoots totally realistic Nerf bullets. Imagine the sheer awesomeness of this on Halloween. Or maybe inside of a corn maze. You could probably get a few people to soil themselves.
