Rip Roaring Racing Balloon
- Round balloon
- Hex nut
- Put the hex nut inside the balloon.
- Blow up the balloon.
- Tie off the balloon opening.
- Spin the balloon in a way that causes the hex nut to travel around in a circle.
- Enjoy the sound of your Rip Roaring Balloon.
How it Works:
As the six sides of the hex nut contact the balloon, it bounces and vibrates creating a really cool roaring sound.
Make This A Science Project:
Try other objects in the balloon. Do different sized balloons work better or worse? What happens if you introduce a small amount of water into the Rip Roaring Balloon?
