Klutz Lego Crazy Action Contraptions

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. Every single one of the 16 projects can be constructed using just the custom selection of LEGO bricks that come with the book. Written by Doug Stillinger. For ages 7 and up.
