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!

Explanation:
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.
