LEGO Crazy Action Contraptions

Sixteen high-performance LEGO contraptions that spin, stretch, launch, and speed into action, each built from a curated set of more than 100 LEGO pieces that comes packed right into the kit. Doug Stillinger's step-by-step diagrams walk builders through projects like the Supercharged Speedster, the Squeezeclaw Grabber, and the Wall Rocket Racer, turning basic LEGO mechanics like gears, axles, and rubber bands into working machines that actually do something once they're built.

The spiral binding keeps the book flat and open on the table while hands are busy with bricks, and every piece has its own spot in the attached storage tray so nothing gets lost between builds. It's a solid pick for kids who are ready to move past standard instructions and start understanding how simple machines actually work.
