What’s it about?

When you tap a glass bottle with a spoon, it makes a sound at a particular pitch. It is vibrating or ‘resonating’ at that pitch which has a particular frequency, for example 300 beats per second. You can make a glass bottle vibrate at various pitches to produce music, by filling the bottles with water to different levels, as you will see in the following science experiment:

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

In this science experiment, when a bottle is tapped with a metal spoon, it causes the air inside the bottle to vibrate, which produces a sound. The amount of water and thus also the amount of air inside the bottles, affects the sound it makes. More water and less air produce a lower pitch, and less water and more air produces a higher pitch.
