Who doesn’t get a charge out of wearing a balloon hat?
In this make and take, students can get creative as they make their own balloon hats and explore the properties of static electricity.
If you've ever rubbed a balloon on your head or tried wearing a balloon hat, you may have noticed that strands of your hair can start to repel each other leaving your hair looking quite messy. This is because electrons move from the atoms and molecules in your hair, onto the balloon.
Electrons have a negative charge, so the balloon becomes negatively charged, and your hair is left with a positive charge. Since like charges repel each other, this causes the strands of hair to spread away from each other.
