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 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.
