The fun of a Marble Machine, miniaturized for your desk, now battery powered!
You are probably familiar with its older cousin, the Solar Marble Machine that has a clever circuit that delivers short bursts of energy collected by the solar cell to the gear wheel.
The battery pack edition of the Marble Machine kit has splendid electromechanical appeal, delivering 8 steel balls down a laser-cut fiberboard frame. Unlike its solar-powered cousin, it’s ready to run at your command.
