Surprising Senses Experiment

Make a Long-Distance Call

Materials you will need: • String (10 metres ) • Two Plastic Cups or Yogurt Pots

Steps:

1.  Make a hole in the bottom of both plastic cups.
2.  Thread one end of the string through the bottom of one cup and tie a knot inside the cup.
3. Thread the string through the other cup and tie a knot inside the cup.
4.  Have a friend hold one cup and you hold the other. Make sure that the string is tight.
5.  Whisper into your cup whilst your friend listens through the other.

The sound of your voice makes the string vibrate, carrying the sound to your friend’s ear.

Check out how Sounds and Vibrations work on our Science Facts page below.
