Fruit Battery (Make Electricity From Fruits)

Even fruits can make electricity and if you be lucky, you may even get enough electricity to light up a light bulb. The electricity produced by fruits can easily be measured using a multi-meter. In this project you compare different fruits for the amount of electricity they can produce. Find out if sour taste and acidity of fruits can contribute to the production of electricity.

This project is a safe version of other battery projects that use corrosive chemicals.
The electricity from fruits is important because it also indicates the concentration of minerals available in fruits. You can also use this method to compare the quality of different potatoes or different oranges. This is an experimental (investigatory) project.
