Dancing rice

You Will Need

  • A Large bowl
  • Plastic wrap
  • Uncooked rice
  • Drum (or pot and a spoon to hit it with)

What To Do

  1. Stretch the cling wrap over the large bowl. Make sure you put it on nice and tight!
  2. Sprinkle a little bit of rice on top of the cling wrap.
  3. Hold the drum close to the bowl and bang it.

What’s Happening?

When you bang the drum it creates vibrations. These vibrations (sound waves) travel through the air. You can’t see them but you can see their effect. When the cling film is hit by sound waves, it vibrates causing the rice to ‘dance’.

Try doing the same experiment with different things on the cling wrap like salt, hundreds and thousands or sand. Which dances the best? Does banging louder or softer make the rice dance more or less?

Did You Know?

When the vibrations from sound waves reach our ears they make tiny hairs in our inner ear vibrate. These vibrations are what allow us to hear the sound. Sound waves travel better though solid objects than air.
