1849-2 Solar Cells Demonstration
This is a great desktop item and attention-getter. Four powerful solar cells are mounted on a revolving disk and motor. This in turn is mounted to a plastic stand and base. Watch as the entire disk, solar cells are included, begin to whirl around when the unit is placed in the sun.
