Ulrik Pilegaard and Mike Dooley both worked at LEGO on the LEGO MINDSTORMS product and have written the ultimate handbook on things you should not build with those colorful little blocks. Wouldn’t you love to know how to build a LEGO robot with automatic LEGO weapons as arms that could fire non-lethal LEGO blocks? We know we sure would. “Forbidden LEGO” teaches you how to build a toy gun that shoots LEGO plates, a candy catapult, a high voltage LEGO vehicle, a continuous-fire ping-pong ball launcher, and more. Awesome.
