Fruit Battery

Can you make electricity from fruits and chemicals?


Chemical energy stored in different substances can be converted to electrical energy. This ability is the foundation of design of all batteries.  

Each battery has two poles usually made of two different metals. One pole is the positive pole and the other is the negative pole. Electrons can travel from negative pole to the positive pole via a conductor such as a wire. A flow of electrons in a conductor is called electricity and if large enough, it can be used to make electro magnet, light up a light bulb or run an electric motor. Inside each battery there are chemicals that cause such chemical reactions. These chemicals in general are called electrolytes. We are wondering if fruits and fruit juices can be used as electrolytes to make batteries.
 Project description:
In this project you will perform experiments to make electricity from a variety of chemicals and fruits. As a part of your research, you may also compare the electrical voltage that can be made with different fruits. What do you think? Can you get more electricity from lemon or potato?

This project is also known as potato battery.
