When you rub a balloon on wool or your hair it creates static electricity. Static electricity is negatively charged particles (called electrons) jumping over to positively charged objects. When you rub the balloon against your hair (the most fun option) it becomes negatively charged. It has taken some of the electrons from the hair and left them positively charged.
The positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.
To show how static electricity works we tried out a variety of experiments. We got some balloons and rubbed them on our jumpers, the carpet and hair to negatively charge them. We then tried to attract a variety of items such as tissue paper, straws, cans and salt and pepper. We also observed during our experiments that some students were great conductors of electricity!
