Packed full of ideas, instructions, and inspiration for 10 LEGO machines that spin, swing, pivot, roll, lift, and drop. Each machine alone is awesome, but put them together and generate incredible chain reactions. Then, combine the machines in any order you like to create your own chain reactions. Klutz experts worked with educators and 11-yr olds to invent the machines, then wrote a book that teaches the skills (and some of the physics behind the fun) kids need to create their own amazing chain reaction machines. Includes 33 special LEGO elements that combine with basic bricks from your collection to make your machines go. Klutz worked with LEGO to make sure you'll need only the most common bricks, and that there are plenty of substitutes. The result is a chain reaction of fun, as one thing leads to another... and another. Includes 80-pg book, 33 LEGO elements, 6 LEGO balls, 6' of string, 8 paper ramps, 2 paper pop-up signs, 1 paper funnel ramp, 1 paper flag, 1 paper bucket,...
