How to Move Things with Sound/Acoustic Propulsion

How to move things with sound, or acoustic propulsion, using the resonance frequency of two soda bottles. I move the two soda bottles using a speaker playing a sound with a frequency of 173 Hz, the Helmholtz resonance frequency of these bottles, the bottles being Helmholtz resonators.
