Blow two balloons right up and join them with string. Rub both on a woollen pullover and let them hang downwards from the string. They are not attracted, as you might expect, but float away from each other.Both balloons have become negatively charged on rubbing because they have taken electrons from the pullover, which has now gained a positive charge. Negative and positive charges attract each other, so the balloons will stick to the pullover. Similar charges, however, repel one another, so the balloons try hard to get away from each other.
