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. Be a scientist as you discover how to power the digital clock with potatoes

The famed potato clock seems impossible, but an easy science experiment can give you insight into how this basic battery works. You already have most of the materials you need. A trip to the basement work area, the pantry and the kitchen drawer may help you complete your recipe for a potato clock.


How to Make a Potato Clock kevin Parker , January 20, 2017 Making a potato clock is a fun and educative science project that can help them learn about electricity and circuits.


In the whole realm of the potato clock (a big Oxidation/Reduction Reaction of sorts), the potatoes just serve as electrolytes that transfer electrons through the wire to the clock and back to the other potato, creating a circuit. Zinc is labeled as the Anode and Copper is known as the Cathode.


Do exactly the same thing as you did with the first half potato i.e. insert the coin and the nail into each potato. Now what you need to do is to make a circuit. Connect the coin of the 1st potato to the zinc nail of the 2nd potato with a wire. Next, using another wire, connect the coin in the 2nd potato to the nail in the 3rd potato and lastly ...


To make a potato battery you will need two galvanized nails, two copper coins, two potatoes, three alligator clip leads with clips on both ends, and a small clock. Galvanized nails are regular nails that have a zinc coating that is necessary for this experiment. They can be found at a standard hardware or home improvement store.


Learn cool science facts with the Potato Clock! Designed for ages 8 years and older, this fun kit teaches kids how to use potatoes to make your own digital clock---without batteries! Contents include: digital clock with wires, pots connecting wire, transparent tapes, copper and zinc strips, and detailed instructions. Potato Clock


Safe and easy to operate, the Two Potato Clock works by capturing electricity created by a chemical reaction inside of the potato. Sure to turn heads at the office, and a great conversation starter at home, the clock never requires any batteries--only a fresh set of tubers (any variety will do) once in a while.
