Drew was the Super Scientist at his school last week. He was required to do an experiment and teach the class something. He chose an experiment on centripetal force and sound. Using balloons to create the centripetal force, he showed the class that putting a penny inside the balloon and spinning it around, it was quiet because both the penny and the balloon were round. But putting a hexnut inside the balloon and spinning it around and around made the balloon "scream" with sound because it has sides and the sides were vibrating against the round balloon. It was a lot of fun and the kids loved it when the balloons made sound. We also distributed two balloons, a penny, and a hexnut for each of the kids to take home with them and try the experiment with their families.
