Lego Crazy Action Contraptions (9781591747697)

LEGO® Crazy Action Contraptions is a book of never-before-seen, 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 (including every brick, gear, and axle).

Comes With: 105 LEGO bricks.
