Fact-Checking this Viral Bottle Trick

A thought on Sonoluminescence: what if the light emitted when the voids collapse is an electrostatic discharge caused when the water changes phase rapidly from gas back to solid under the added pressure of the water's weight. Almost like the collision causes an electron to temporarily dislodge and then reorient or change places with an adjacent molecule without destabilizing the molecule  it came from. That is a head scratcher indeed! Great Video!
