Materials
- Bowling Ball with Ceiling Hook
- Wire or strong twine/string
- A Place to Hang it
Safety Precautions
Please read the Physical Demonstration section of the Demonstration Safety page before performing this demonstration.
This demonstration requires: Safety Glasses
Demonstration
- Loop the wire on a bar or hook int he ceiling of the presentation space. Give it enough slack so that, when you hang the ball from it, the ball will be about 4 feet off the ground.
- Explain to the audience that the ball is currently hanging like a pendulum, and briefly talk about pendulum motion.
- Grab the ball and pull it back, walking backwards until you can have the ball level with your face. Hold it up against your face, and ask the audience if they think it might hit you when you let go and let it swing.
- Release the ball. On the return swing, it will get close to your face, but won't hit you!
- Note: When you release the ball, make sure that you don't lean forward. Otherwise, you might end up leaning into a face tap with the bowling ball!
