What You Need:
- 3 foot length of string or thread
- Tie the fork to the center of the string.
- Tie one end of the string around your right index finger, and tie the other end around your left index finger.
- Touch your fingers to your ears and let the fork hang in front of you.
- Have a friend tap the fork with a spoon and you’ll hear a loud ringing in your ears! The sound has traveled up the string to your ears.
Try tying other metal objects to the string and see what sounds they make.
