3D Wooden Puzzle — Electric Catapult Marble Run

A wooden marble run you build yourself, with an electric lift that carries marbles back to the top and a catapult that launches them along the track. Seven marbles race through the finished machine, making gravity, momentum, and gear-driven motion easy to see.

Adult supervision recommended: Best built together with a parent or adult, especially for younger builders.

Warning: CHOKING HAZARD — Toy contains marbles and small parts. Not for children under 3.
