The Solderless Solar version of the Gravitrack marble machine brings the same tick-tock pulse movement but with none of the molten metal!

The only tools required to get this beauty running is a phillips-head screwdriver, a sharp edge, and a bit of elbow grease.

Watch as the sun powers the slow but elegant hand-off mechanism that passes marbles to the top of a sweeping multi-level track. You will witness the fascinating step-by-step action of the arms as the geometry changes periodically.

Patience is rewarded with the plunk, and roll of a successful motion cycle. The more light it gets, the more often it moves. It’s solar-powered stop-action motion!
