3C20.25 - Musical Pop Bottles

Fill the pop bottles with water to different levels and hear the different resonance frequencies. This shows the resonance of an adjustable cavity.  Pop bottles may be considered Helmholtz resonators and not closed pipe demonstrations, as the resonance depends on the column of air in the bottle.
Code Number:
3C20.25
Demo Title:
Musical Pop Bottles
Condition:
Excellent
Principle:
Resonance in Pipes
Area of Study:
Acoustics
Equipment:
Pop Bottles and Water.
Procedure:

Fill the pop bottles with water to different levels and hear the different resonance frequencies. This shows the resonance of an adjustable cavity. 

Pop bottles may be considered Helmholtz resonators and not closed pipe demonstrations, as the resonance depends on the column of air in the bottle.
