Very neat. These days the majority of researchers do not believe fusion can occur inside the collapsing bubble because the temperatures do not reach fusion values. They think it is some chemical reaction that is not fully understood. This actually occurs in nature.

Anyone know what program this is from? Or how to make a star in a jar at home?

A speaker, a two liter bottle of water, a straw, and a lot of patience.

This happens with ?pistol shrimp? right?

Degassed water helps, too.

We did this as an experiment in undergrad. Degassed water, a container with a simple shape (we just had a rectangular prism), a thing to vibrate it, and a thing to control the amplitude/frequency of vibrations. We usually got three or four nodes, depending on how good we were doing.

It was quite a while ago, but I think we had a piece of equipment we used to tell whether we were getting close to a resonance, and then it was just by feel to actually get sonoluminescence to happen. Cuts down on the amount of patience required, but still takes a bit.

Three or four nodes meaning three or four lights going?

Yeah, sorry. Three or four lights. Our container was like... 2x2x4 inches or so, maybe? The bottom face was square, and then it was twice or more taller than that, anyway. So we'd usually get one light about a half inch or an inch from the bottom, but centered with respect to the square side, then another one roughly in the *actual* middle of the water, then another one close to the surface. And then, the weird one was that we'd get a fourth close to one of the upper corners.

The middle and bottom ones were pretty consistent. Wouldn't always get the other two. And I might actually be misremembering getting the top center one. We were using a kinda novel way to measure the spectrum to measure the temperature of it. If we'd put a little more work in, it probably would've been a publishable result. But, lazy-ass undergrads.
