A lemon battery is a classic science experiment used to demonstrate the basics of a chemical battery system. To recreate this experiment, you will need one very juicy lemon, a galvanized steel nail, a clean copper coin and a sensitive voltmeter. Voltmeters can usually be found in the electrical supply section of a hardware store, electronic hobby store or home improvement center.

A lemon battery is a battery used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects, for example a galvanized nail and a copper coin, into an ion bridge . The copper coin serves as the negative electrode or cathode and the galvanized nail as the electron-producing positive electrode or anode.

A single lemon battery will not produce a significant amount of voltage, but a sensitive voltmeter should detect some electrical output. Show your audience the voltmeter's original reading of zero volts. Connect the positive clip to the copper coin or wire and the negative clip to the galvanized nail. The digital readout or analog dial on the voltmeter should show a small voltage number, usually less than one-tenth of a volt.
