Description

A lemon powered light bulb is a great science project or even a great green solution for camping or power outages. Lemons are able to power many small electronic devices including light bulbs. The acid in the lemon causes a chemical reaction with the two metals inserted into the lemon, resulting in an electrical current. The following article outlines the process of powering a light bulb with a lemon.

Resources

Two lemons
Stiff copper wire
Large Steel Paper clips
Thin copper wire
Light bulb (small, like a flashlight bulb)

Instructions

Take the two lemons and roll them on a table, applying pressure with the palm of your hand. This will cause the juices to release from the pulp so you can get a good "battery" for your light bulb. Make sure they get good and soft without breaking the peals.

Take the stiff copper wire and cut two lengths, several inches long. Press one of the wires into each of the lemons. The stiff copper wire is represented by the red lines in the diagram.

Unfold the large steel paper clips. Press one into each of the lemons. These are represented by the gray lines in the diagram.

Using the thin copper wire, connect the copper post in the first lemon to the steel post in the second lemon. Then connect the remaining 2 posts to the light bulb as shown in the diagram.
