A Klutz classic gets bigger, better, and even crazier. LEGO Crazy Action Contraptions is a brand-new book of brand-new, high-performance projects. From the Supercharged Speedster to the Squeezeclaw Grabber to the Wall Rocket Racer - all these contraptions spin, stretch, speed, or otherwise spring into action. And all of them are totally buildable thanks to super-clear instructions and step-by-step diagrams. Wonderful as the original book was, this new version is even better, and here's why: In the earlier book, five of the ten projects required bricks that you (hopefully) had at home. In this new version, every single one of the 16 projects can be constructed using just the custom selection of LEGO bricks that come with the book. All you need to supply is a little time, a little energy, and definitely a little craziness.
