Fact-Checking this Viral Bottle Trick

Cavitation works on the principle of vacuum pressure. Its easiest to produce in earth gravity with liquids. Its also the future of chemical energy  which I'm personally working on. If your interested let me know. Oh and the flash of light that is seen in the ballistic gel is caused by the drop in pressure. the drop in pressure is accompanied by a drop in electron pressure which allows some of the electrons to jump to a higher energy level when the bubble collapses. This works on the same principle as phase change. a liquid needs energy to change from a liquid to a gas. when the bubble collapses the extra energy is emitted as photons. Similar to how a laser works. throw some comments and thumbs up at me if you think I should make a video on the subject.
