A coins battery

Here is a small project of a 'Volta' battery named after the Italian inventor Alessandro Volta.

 

The Swiss 5 ct coins are composed mainly of copper which is ideal for a chemical reaction in a battery.

 

The use of a led bulb makes it possible to produce a little light even with a very small electricity production.

 

This project was developped for the magazine 'Campus Junior' of the University of Geneva.
