MAKING MUSIC WITH WATER

456

 

 

Have you ever tried making music with glasses or bottles filled with water? 

What you'll need:

  • 4-5 drinking glasses or glass bottles
  • Water
  • A pencil

                                                                                                                                    

Instructions:

  1. Line the glasses up next to each other and fill them with different quantity of water. The first one should have just a little water while the last should be almost full.
  2. Hit the glass with the least amount of water with a pencil and observe the sound, then hit the glass with the most water, which makes the higher sound?
  3. Hit the other glasses and see what noise they make, see if you can get a tune going by hitting the glasses in a certain order.

 

What's happening?

Each of the glasses will have a different tone when hit with the pencil, the glass with the most water will have the lowest tone while the glass with the least water will have the highest. Vibrations are made when you hit the glass; this creates sound waves which travel through the water.
