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.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.Contents include: 78-page book of instruction and inspiration, 33 LEGO elements, 6 LEGO balls, 2.2 yds (2 m) of string, 8 paper ramps, 2 paper pop-up signs, 1 paper funnel, 1 paper flag, 1 paper bucket, 1 platformFor 1 playerAges 8 and upMade in South KoreaBrand new condition in original packagingWipe clean with dry or damp clothWarning: Choking Hazard - Contains small parts not suitable for children under 3 years.
