Fruit Battery Power Generation Principle
The fruit contains an electrolyte such as citric acid, and two kinds of metal sheets with different chemical activities are inserted into the fruit, wherein the more active metal sheet can replace the hydrogen ions of the acidic substance in the fruit, and the positive system generates a positive electric charge. It needs to be stable, so in the case of constituting a primary battery, the stability of the system is maintained by the electrons from the circuit. In theory, the magnitude of the current is directly related to the concentration of fruit acid.

This is a really cool science educational kits for children to learn the basic principle of battery.
