Lego Chain Reactions: Design and Build Amazing Moving Machines - Ages 7-9 - Paperback - Pat Murphy
Have you ever basked in the excitement that is watching a Rube Goldberg-like contraption unfold? Well, now you can build one of your own while learning all about the physics behind it! Using over thirty LEGO elements, plus a few rolling spheres, you get to build ten brilliant contraptions that all come together to create an amazing chain reaction. Page by page, detailed instructions help you perfectly build each mechanism while learning how and why everything works. Send a tire spinning around a pole to launch a hammer and lift a sign. Spin a windmill to keep the ball rolling and then start a reaction that zig-zags upwards. Build a pulley that launches a ball, a wild spinning vortex, and an amazing zig-zag finish line! Then, once you've finished building everything, put it all together and watch as it spins, pivots, rolls, lifts, and drops all in one amazing, continuous motion! Who cares if it doesn't do anything useful? The fun is in watching it all go! Designed and written by a genius team of experts, educators, and 11-year-olds, the LEGO Chain Reactions kit opens up children to just how amazing physics can be.
