As long as there’s light, The Solarbotics Perpetual Motion Marble Kit will keep on moving its marble from bottom to top. Oh, and the fun part? It’s a kit that you have to build yourself!
Once built, the Solarbotics Perpetual Motion Marble Kit will collect energy from its solar cell. Then, it will release that energy in pulses turning the gear wheel. The gear wheel elevates marbles to the top and then drops them down a super fun (if you’re a marble) twisty slide. If you are in bright sunlight, the pulses will cause a ball to drop every minute (less if you are using indoor light). The Solarbotics Perpetual Motion Marble Kit – convince the world you have conquered science!
