Laboratory activity demonstrates resonance phenomena in double-walled bottles, highlighting experimental data and theory interaction.

The aim is to explore the resonance frequencies in a double-walled water bottle and how they change with water level.
Studied two resonances through striking the bottle and blowing across its neck.
Measured frequencies using free audio software.
Varied water levels in the bottle to observe frequency shifts.
Different tones resulted from the inner and outer walls oscillating.
Helmholtz resonance was produced by blowing or striking the bottle.
Frequencies shifted oppositely with changes in water level, causing audible beating effects.

Ludwigsen et al. (2026) studied this question.
