Learn about electricity and chemical reactions in an innovative way
The Two Potato Clock allows you to generate enough electricity to run a digital clock – using potatoes! Just push the zinc and copper electrodes into the potatoes causing an oxidation/reduction reaction that is converted to low voltage. For ages 14+.

Potatoes work as batteries in this clock, possessing enough moisture and ions to be electrically conductive. A potato battery is a type of electrochemical cell, converting chemical energy into electrical energy. The potato conducts electricity, and also keeps the zinc and copper ions separate so that the electrons in the copper wire move, generating current.
