Forbidden Lego - $16.47

Using LEGO bricks in combination with common household materials (from rubber bands and glue to plastic spoons and ping-pong balls) along with some very unorthodox building techniques, you’ll learn to create working models that LEGO would never endorse.
Try your hand at a toy gun that shoots LEGO plates, a candy catapult, a high voltage LEGO vehicle, a continuous-fire ping-pong ball launcher, and other useless but incredibly fun inventions. Because sometimes, breaking the rules is what it’s all about.
