Gravitrack marble machines by Solarbotics


Gravitrack is a fantastic new build-it-yourself desktop-scale marble machine kit from our friends at SolarBotics, and available now at our store.

Gravitrack is available in two versions: A no-soldering battery-powered version (shown above), or a soldering-required solar version. We also still carry the original SolarBotics Marble Machines, in battery and solar flavors.
