The clock is now running on potato power. A potato clock runs on a potato instead of a conventional battery. A potato "battery" is a type of electrochemical cell. In the potato, electrons are transferred between the galvanized nail and the copper nail, conducting electricity. This is a low-power homemade battery; it will not give you an ...

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 process to create a potato battery powered clock is similar to the potato battery powered light bulb. The negative and positive terminals of the light bulb are simply replaced with the negative and positive terminals of the clock. The voltage generated by a potato can also be tested by replacing the light bulb/clock with a galvanometer[sc:4].

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 ...
