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.
— As of 05/12/2011 this product had 4.7 out of 5 stars from 15 reviews on Amazon.com. Cons: Some contraptions run slowly; the included rubber bands wear out with time.
— "Klutz Lego contraptions is by far our biggest seller," Mary Porter Green, owner of The Curiosity Zone in Asburn, Va., told TDmonthly in late Spring 2011.
