Working principle:
Metal strips and potatoes, and created a simple battery operated clocks. Each potato as an electrochemical cell, which is stored in a metal band that convert chemical energy to electrical energy. Two potato clock is powerful enough to run the electricity.
A battery works is because the chemical properties of metals (copper and zinc). Different properties, resulting in electricity consumption charged particles (called ions) move between the two metal strips. This flow is current. Potatoes contain particles causes a current to flow through, but it prohibits the metal contacts. Currents along wires between the copper and zinc bars and clock movement, the currents make the clock work.
