What happens when you collapse an underwater bubble with a soundwave? [Totally amazing!!!]

Sonoluminescence : How Bubbles Turn Sound into Light

[miliantnutcase]

Holy crap.

[Born to Conserve]

Typical “piece”: zoom in on people’s faces, intersperse a few stock animations, and don’t show anything real.

Garbage.

[the_Watchman]

So many visual effects have been added that it is difficult to ascertain what is real in this video.

I thought it was just me. Thanks....

‘Twould be nice to have just a teeny bit of physics mentioned.

As is was ‘fraud my bull Obama light is on.

Fart in a bathtub as produced by Cal Arts film student

[JSteff]

Garbage.

Worse yet, how many tax $$$ went to create this triffling diversion?

[rickmichaels]

Wow. I regret posting this.

[laplata]

Cool. Thanks, rickmichaels!

Bubble is formed and rides the sound wave to center of chamber (think of an eggcrate formed by sound waves). Then you tune the sound waves in such a manner that the bubble expands (pressure drops) during one phase and then collapses on itself during the compression phase. Once pressure increases (along with temperature), the gas will radiate. Temperature are hotter than the sun, but not high enough for fusion (has been tried about 10 years ago with deuterated water and acetone fluid). Seth putterman at ucla worked on this.

Yes but if it caused fusion, that would in turn jump the economy which is against the law of liberals who would immediately in turn call for water regulations and sound locks and a total ban on Mr. Bubble.

BANNED!

Looks pretty cool to me (link).

[Chode]

and the heat never escapes the bubble along with the light, right? feh...

Jacuzzi!!!

Billy Ray: When I was growing up, if we wanted a Jacuzzi, we had to fart in the tub.

[DanielRedfoot]

O don’t be, its really pretty cool, Thanks for doing so

[Hardraade]

Fusion in a hydrogen bottle??

I want one. I have uses for a reasonably simple and cheap thermonuclear device.

[equaviator]

We can only hope.

[tanuki]

I thought it was pretty cool. I don’t know what’s wrong with the haters.

IIRC Putterman’s group (and a few others) thought they had seen excess neutrons (the kind that indicate D-T fusion reaction is occurring), but they could never conclusively prove it was not coming from the natural background or calibration sources.
