This is where electricity stops feeling abstract and starts doing something your teen can see. Solenoid Engine Deluxe Kit walks your teen through building a working motor where every moving part stays out in the open.
Your teen assembles nearly 400 LEGO‑compatible pieces, including electromagnets, a crankshaft, pistons, and a flywheel that keeps everything turning smoothly. As it comes together, each section shows how motion moves from one part to the next.
Nothing is hidden. The magnets pull, release, and repeat, driving the pistons and spinning the system in a steady rhythm. Your teen can see exactly how electrical energy becomes movement.
The Deluxe version gives your teen more to explore after the main build. It includes unusual gear sets—nautilus, oval, square, Geneva mechanisms, and direction-changing gears—so the motion can be changed, tested, and rebuilt in different ways. Your teen adjusts, troubleshoots, and tries again until everything moves smoothly.
Once built, it doesn't just sit there. The engine runs, the gears change how motion behaves, and the whole system becomes something your teen can keep experimenting with.
It's a bigger project, but that's the point. Your teen sees how electricity, motion, and design work together as he builds it piece by piece.
