This interactive book contains amazing ideas, instructions and inspirations for 10 LEGO machines that can spin, swing, pivot, roll, lift and drop.
While each machine is awesome on its own, when combined, their chain reactions will simply blow your mind away!
The Klutz team of experts worked hard with educators to invent these machines and teach the physics concept behind these contraptions.
33 special LEGO elements are included, in addition to your own collection of basic LEGO bricks, to make the machines a reality.
