So How Exactly Does a Potato Clock Work?

Potato Power – A potato clock is powered by acid within the spud reacting with a positive and a negative electrode. When the reaction occurs, electrons flow between the materials, generating an electric current. The negative electrode, or anode, in a potato battery is often made from zinc in the form of a galvanized nail. The positive electrode, or cathode, is often made of copper, which could be in the form of a penny. Potato Power A potato battery to power a clock requires only a potato, two pennies, two galvanized nails and three insulated copper wires. When the zinc nail inserted in one end of the potato contacts the mild phosphoric acid (H3PO4) within the potato, it loses electrons in the reaction. These electrons are then picked up by the penny inserted into the other end of the potato. This “flow” of electrons is an electrical charge. Although the potato battery only generates a few volts of electricity, researchers from the Hebrew University of Jerusalem announced in 2013 that they have made serious progress in developing a potato-based power supply that could be used to charge a cell phone or laptop computer.

A potato clock runs using electricity generated with potatoes.


Video advice: Why Does A Potato Battery Work Better Than A Lemon Battery?

Back in 1st Grade I made a potato battery as a school project. I didn’t really give it much thought then, but now revisiting it, I realized how complex and amazing electrochemistry is!


The energy comes from the chemical change in the zinc when it dissolves inside the mild phosphoric acid content of the potato. The energy does not come from the potato itself. What happens is that the zinc is oxidized inside the potato, exchanging some of its electrons with the potato acid in order to reach a lower energy state, and the energy released provides the electrical power.

2) The electrons produced in the above reaction travel out through the zinc, through the wire, and into the copper strip also inserted in the potato. They do this because they are attracted to the positive hydrogen ions in the potato, located on the copper side (these hydrogen ions are there due to the acid content of the potato). Since the electrons cannot pass through the potato itself, they pass through the wire joining the zinc and copper strips. These electrons then combine with these positive hydrogen ions (on the copper side) and produce hydrogen gas, which then bubbles away.

“What makes the potato clock work is the large voltage difference between the copper and zinc. It causes a current to follow through the potatoes to drive the clock. There’s a voltage difference between the two metals that makes it possible. The bigger the difference, the stronger the reaction.

Ryan makes a real working clock using fruits! Fun Potato Clock Easy DIY Science Experiment for kids! Learn about how a potato clock use acid to react with the positive and negative electrode!


How it Works – 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. You’ll need two galvanised nails, several inches of copper wire and wire clips, an LED clock with the battery removed, and a potato or two. 1Assemble the Clock Assemble the clock by first putting one nail into each potato or potato half. Insert a length of copper wire into each potato or potato piece such that it does not touch the nail. Take one part of the two-piece potato battery and attach the copper wire to the positive end of the LED clock’s battery attachment. Take the second part of the potato battery--the other potato-wire/nail combo--and attach the zinc-coated nail to the negative portion of the LED clock’s battery attachment. Attach the remaining zinc nail and copper wire together, completing the circuit.

What a Potato Clock Can Teach Us About Fighting Disease

Did you ever make a potato clock as a kid? Did you know that the reaction that makes elementary school potato clocks tick could also fight infection and disease?

These studies also reveals a credit card applicatoin for killing cancer cells. The body commonly has mechanisms to prevent cells from dividing uncontrollably, however when it fails to do this, cancer develops. The negative voltages that Gilbert and the fellow researchers apply induce cellular apoptosis, or cell dying, so it might be a means of killing cancer cells that don’t obtain the message to die out naturally.

Gilbert, an expert in biological implants like hip replacements, believes that one way these findings could be put to use in infection prevention for titanium implants. Infections that take hold on the surface of implants are notoriously challenging to defeat. They withstand even the most powerful antibiotics. By adding magnesium to the titanium surface of an implant, the implant itself is given the ability to kill bacteria before they are able to harm the patient.

How long does a potato clock work?

A couple years ago, researchers at the Hebrew University of Jerusalem released their finding that a potato boiled for eight minutes can make for a battery that produces ten times the power of a raw one.

How does the potato clock work for kids?

A potato battery is an electrochemical battery. This is also called an electrochemical cell. These cells are places where the chemical energy is turned into electrical energy through the sudden transfer of electrons. In a moment, you're going to be sticking galvanized nails and copper wire into potatoes.

Why do you need two potatoes for a potato clock?

The potatoes both conduct electricity and keep the zinc and the copper apart from each other, allowing an electric circuit to be created. The movement of electrons generates electrical power for the clock.
