The observed shockwaves are especially impressive.

Here because of the Titan implosion but reminded why Fluid Dynamics was one of my favorite classes in undergrad

Wow. Learning about ultrasonic cleaners. I was stuck on cavitation. Now, I can see it.

Bubbles collapse into violent shockwave-indicing events and stars collapse into black holes. It seems collapse is very common in nature.

Looks like a microburst, I wonder if bubbles of moist air collapse against the stratosphere, creating the downward jet?

Interesting idea, but I wonder considering macro vs. micro phenomena etc.

Do you have a version that is deeper, an not near the surface?

I would bet this keeps the bubble in viewing vicinity.

Can any one say why bubble initially expands and sudden compression???

It’s at 0:08 “A cavitation bubble is created with a focused laser pulse in the vicinity of a free surface.” At 0:30 “Before reaching its minimum radius, the bubble is pierced by a free surface-induced jet.” (That is, the jet is induced by proximity to the free surface.)
