HOW LISA RECHARGED HER MOBILE IN BULGARIA

   In Bulgaria I recharged my mobile using mechanical energy. It was easy and a lot of fun!

              You need:

1.    1. A hamster – as hardworking and vigorous as you can find!

2.    2. A wheel that the hamster can turn

3.      3.   A small dynamo machine taken from a bike that transfers the energy from your peddling into electricity to power the bike’s headlights.

4.    Connecting cables.

I put the hamster in the wheel and he started turning it very fast. The wheel was connected to the dynamo machine which transferred the mechanical energy into electricity and it recharged my mobile.

When we replaced the mobile with a small light bulb it really gave light when the hamster was turning the wheel fast enough.
