Just in time to try this fun Halloween inspired activity that uses science to make bats dance. With a few simple items, kids and their parents can get batty while incorporating science, technology, engineering and math (STEM).
Shake it up! What happened?
The bat is attracted to the balloon because of static electricity – the thing that makes you go “Zap” when you walk on carpet in your socks. Everything is made up of atoms and atoms have three parts – electrons, neutrons and protons. Electrons circle the nucleus and are the easiest part of the atom to “lose” because the nucleus, which is made up of protons and neutrons, has a weaker pull on them. When two objects rub together, the electrons mix.
The balloon picks up extra electrons from the sweater or your hair and becomes negatively charged. Well, with electrons, opposites attract. So, when you put this over the bat, the bat is attracted to the balloon, because it has a positive charge and therefore, it “dances.” What happens if you remove the tape?
