At home for 5-11 11-14

What you need

  • Two pieces of string
  • A fork


  1. Tie a piece of string to each corner of the coat hanger and wrap the ends around your fingers
  2. Put your fingers in your ears and ask your friend to tap the hanger with the fork

Results and Explanation

It sounds louder because vibrations travel through the metal and string more easily than through air.

These experiments have not been specifically safety tested for home use but we believe them to be safe if the instructions are followed. Adult supervision or direction is recommended as appropriate. All experiments are carried out at your own risk.
