Make a Xylophone

Make a Xylophone

5-6 glass beakers
Water
Wooden pencil

What you do

Line the beaker up
Pour different amount of water in the beaker
Lowest to highest
Use a pencil and tap to hear the noise

What happened 

It makes different sounds
Least water made highest.

Why

The sound waves travel
trough liquid. By chaging the the amount of water, the sound waves change.
