Tin´s race

In order to make this experiment you need the following materials:

1. An empty softdrink can.
2. A baloon. If we don' have, we can use expanded polystyrene (white cork)

In order to continue with our experiment we make the following procedure:
1. Blow up the baloon.
2. Rub the baloon against your hair or a wool article (for example a scarf).
3. Put the softdrink can knocked down on a table and we approach the baloon. After doing this, we can check that the softdrink can move!

This happens because when rubbing the baloon electricity loads. The attractive electrical forces between the loads or different signs of the baloon and the softdrink can make the tin rotates.
