I have my depth study on module 3 and specifically resonance and I have my idea which is:
How changing frequency affects the rotational speed of a system.

This is based on the Helmholtz frequency of a bottle and my system involved 2 bottles attached to a stick that faced opposite sides on opposite ends of the stick and is suspended like this image.

I thought I could use an ordinary speaker to replicate the same effects as a subwoofer but it just isn't strong enough. Has anyone done this experiment before and has experimental results or know anyone who has?

Thanks in advance
