Balloons and static electricity

Bubble and I used balloons today to learn about static electricity. She was enthralled by the way her hair stuck to the balloon when we rubbed it across it and sat for a long time trying out different angles and rubbing techniques. I explained to her as simply as I could that there was a build up of things called 'electrons' when we rubbed the balloon on her hair, and that made her hair look like it was sticking to it.

Other ideas: for older children you could draw pictures of how protons, electrons and neutrons work in creating static electricity and how opposites attract.
