LEGO® Chain Reactions by Klutz

LEGO® Chain Reactions is the brand-new Klutz book designed to help kids create amazing moving machines. The book comes equipped with 20 LEGO® pieces, paper ramps and other contraption components, and an instruction book for 10 simple machines. Combine the included Lego pieces with your own Lego sets to build moving modules. The modules can be combined for all-new results and even more fun! Record your experiments right in the pages of the book.

Why we like it: “I like how it comes with tunnels, ramps and twists. You can use the ramp to make the little ball go into the tunnel, which makes the ball roll onto another ramp and knock something over. It’s fun. I like how you can build one thing that leads to another.” – Kid Tester
