Made using safe and high quality materials, just add a lemon for a fun lesson in battery science. Included in the package are copper and zinc plates, wire, and a clock. The required lemon is not included.
The Lemon Clock allows you to generate enough electricity to run a digital clock using lemons! Just push the zinc and copper electrodes into the lemons causing an oxidation/reduction reaction that is converted to low voltage.
