Mechanical Track Ball 3D Puzzle - Wooden Kinetic Sculpture 218 Pieces

Turn the crank. Watch the marble climb. Follow it as it drops through spirals, rolls across bridges, triggers levers, and finds its way back to the start. Then turn the crank again — because you can't not.

This 218-piece wooden kinetic sculpture is part puzzle, part desk toy, part meditation device. You build it in about 5-6 hours, and then it sits on your desk being quietly hypnotic whenever you need a break from the screen.

The anti-screen break

We all need something physical to do with our hands during long work days. This is infinitely better than a fidget spinner. Crank the handle, watch the marble, let your mind wander for thirty seconds. Then go back to work feeling slightly more human. Your colleagues will want turns. Let them.
