Written by a former master LEGO designer, this full colour book contains projects that break the LEGO Company's rules for building with LEGO bricks-rules against building projects that fire projectiles; cutting or gluing bricks; and using non-standard parts. Many of these are backroom projects that LEGO's master designers build under the LEGO radar, just to have fun. Learn how to build a catapult that shoots M&Ms; a gun that fires LEGO beams; a continuous fire ping-pong ball launcher; and more! Tips and tricks will give you ideas for inventing your own creative model designs.
