How to See Sound

Here’s another 5 item science experiment for you, using items that you likely already have in your kitchen.

This one can be pretty exciting for young children because they get to bang on a pan like it’s a drum. Which also means you’ll get some major “fun parent” points.

Have fun with this one!

  • Large Bowl
  • Plastic Wrap
  • 1 teaspoon Uncooked Rice
  • Metal Pan (Cookie Sheets or Pans are good options, but they must be metal)
  • Metal Spoon

Experiment Instructions

Step 1 – Tear off a piece of plastic wrap big enough to cover the top of the bowl.

Step 2 – Secure the plastic wrap over the bowl. Make sure that the plastic wrap is very tight.

Step 3 – Pour 1 teaspoon of uncooked rice on the top of the plastic wrap.

Step 4 – Hold the metal pan in the air and position it next to the bowl

Step 5 – Take the metal spoon and bang on the metal pan like a drum and watch what happens to the rice.

How Does the Experiment Work?

The rice moves and jumps around because of the sound waves that are caused when the spoon hits the pan. These sound waves travel through the air and when then reach the plastic wrap it vibrates causing the rice to move. The sound waves are also what allow us to hear the noise of the spoon hitting the pan.
