Teach your bricks new tricks! Deep in the Controlled Chaos Department of Klutz Labs, we asked a simple question: What could be more Klutzy than a machine that performs a simple task through an elaborate chain reaction? The answer, of course, is a wacky chain reaction built of LEGO bricks. With this in mind, our team of experts, educators, and 11-year-olds helped us invent 10 machines that swing, bounce, spring... and teach kids the skills (and the physics behind the fun) they need to create their own marvelous machines.<br /><br />Our step-by-step instructions make it easy to build the Flag-Waving Marble Kicker, the Barbell Spinner, and more. Young builders set up these machines in any order they choose to form a custom chain reaction. One thing leads to another, and another, and another, as the machines perform an ordinary task (like pushing a button on a keyboard) in an extraordinary way. With this book in hand and a handful of basic bricks from their LEGO collections, the only other thing that LEGO fans will need is a little imagination.
