How Potato Batteries Work

Potatoes are great mashed, roasted, baked or in clocks. That's right, potatoes are nature's tastiest battery. Check out the 411 on the science behind this powerfully delicious snack.

How to Make a Potato Battery

Making a clock run on potato power is easier that you might think. This project is easy, bizarre and makes a sweet science fair project or chemistry experiment. Who knew potatoes could be so empowering?

What You Need:

  • Two Potatoes
  • Two short pieces of heavy copper wire
  • Two common galvanized nails
  • Three alligator clip/wire units (alligator clips connected to each other with wire)
  • One simple low-voltage LED clock that functions from a 1- to 2-volt button-type battery

Steps:

  1. Remove the battery from the battery compartment of the clock.
  2. Make a note of which way around the positive (+) and a negative (-) points of the battery went.
  3. Number the potatoes as one and two.
  4. Insert one nail in each potato.
  5. Insert one short piece of the copper wire into each potato as far away from the nail as possible.
  6. Use one alligator clip to connect the copper wire in potato number one to the positive (+) terminal in the clock's battery compartment.
  7. Use one alligator clip to connect the nail in potato number two to the negative (-) terminal in the clock's battery compartment.
  8. Use the third alligator clip to connect the nail in potato one to the copper wire in potato two and set the clock!

How the Potato Clock works

A potato battery is an electrochemical battery, otherwise known as an electrochemical cell. An electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer. In the case of the potato, the zinc in the nail reacts with the copper wire. The potato acts as a sort of buffer between the zinc ions and the copper ions. The zinc and copper ions would still react if they touched within the potato but they would only generate heat. Since the potato keeps them apart, the electron transfer has to take place over the copper wires of the circuit, which channels the energy into the clock. Presto! You have potato power.

Actually I don't know about all that, but it still seems wrong to just assume that about all girls, even if there are many where you live and in other places that you have deemed as being such

Well, it all depends on religion. Mine is Christianity. So yes, I believe in God. God actually created these animals, but not to become as a test subject. Believe it or not, your call, but animals actually do have feelings. Such as Monkeys, Dogs, Cats etc. If you own a dog or cat, how would you feel if your pet was taken away to become a test subject? Knowing the possibilities that they could die. Not too happy, wouldn't you say?
