LEGO® Crazy Action Contraptions is a 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.

For ages 7 and up
