Fact-Checking this Viral Bottle Trick

Here is my guess : "for the same reason that a nuclear explosion creates light"! As I understand it, a collapsing microbubble is so powerful that it creates heat comparable to the surface of the sun (in a very small area)-(ergo the pitting of propellers). So, is it possible that that amount of heat creates the light, or helps create light by "burning" the fluid? During my class in ultrasound, I "invented" a way to destroy an embolism using high intensity focused ultrasound to make microbubbles in the blood right next to the blood clot. Okay, I didn't make a machine, it was only mentally. Later I found out that there was a Phd.Md. who was working on the same thing, for real. I can't because I have epilepsy and for instance during the last 2 weeks of that semester, I was unconscious in a hospital having seizures. Anyway, thank you for all your shows, I just love 'em.
