Can Sound Move Objects?

Experiments | 7-13 yrs | Video

REQUIREMENTS

  • A sheet of plastic
  • An elastic band
  • A bowl
  • Rice
  • Music Speaker

HOW TO DO

Put the rice on the bowl after you cover it with a plastic sheet and secure it with a rubber band. Play music loudly and bring the speaker near the rice. You will see that the grains of rice start dancing.

WHY THIS HAPPENS

The loud music produces noise which vibrates. This makes the air vibrate as well, producing sound waves. When these waves hit the bowl, the bowl vibrates, making the rice jump about.

TRY THIS Do this experiment- can sound move objects. You will find out what happens.Try making music by putting different items like peas in cans and shaking them. See whether your friends can guess what you’ve used. Try out our other experiments for even more fun. Learn more about sound waves on our site.
