The Solar Marble Machine Kit (Solderless Version)
Marble Motion kit, enabled by Solarengine technology that keeps on moving even in low indoor light!

The Solderless Solar version of the 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, some glue, and a bit of elbow grease.
