Teach your bricks new tricks. LEGO Chain Reactions is packed full of ideas, instructions, and inspirations for nine LEGO machines that spin, swing, pivot, roll, lift, or drop. One machine alone is cool, but put them together and you get amazing chain reactions. You supply bricks from your own LEGO collection; we supply the special elements that make your machines go. One thing leads to another… and another… and another. New 2014
