You may know potatoes as a good source of potassium, but did you know they can be used to power an alarm clock? 7 years & up. 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. Kit allows you to build your own digital clock powered by a potato (other kinds of fruits/vegetables can be used as well) Includes detailed instruction manual guiding the user through the building process and giving fun facts and info Excellent as a science project or experiment The Potato Clock Science Kit includes clock with wires, pots, connecting wire, transparent tapes, copper and zinc strips and detailed instructions
