Super Sound Popper

Learn how to make a fun and easy super sound popper in this sound science experiment.

 

Materials:

  • Cardboard tube
  • Balloon
  • Scissors
  • Masking tape

 

Instructions:

  1. Tie a knot in the neck of the balloon as if you were trying to keep air inside. 
  2. Use the scissors to snip the other end off of the balloon.
  3. Stretch the balloon over one end of the cardboard tube. Center the knot over the opening in the cardboard tube.
  4. Use the masking tape to secure the balloon in place.
  5. Pull back the knot and release to use your Super Sound Popper.

How it Works:

The balloon is elastic. When pulled back and released, it will return to its original shape. While doing so, this makes a popping noise that is amplified (made louder) by the cardboard tube. 

 

Make This A Science Project:

Do different sized balloons or other elastic material change the volume or sound created by the Super Sound Popper? Do different sized tubes change the volume or sound? Does the length of the tube change the sound in any way?
