Scientists have now levitated small live animals using sounds that are, well, uplifting.
In the past, researchers at Northwestern Polytechnical University in Xi'an, China, used ultrasound fields to successfully levitate globs of the heaviest solid and liquid—iridium and mercury, respectively. The aim of their work is to learn how to manufacture everything from pharmaceuticals to alloys without the aid of containers. At times compounds are too corrosive for containers to hold, or they react with containers in other undesirable ways.
"An interesting question is, 'What will happen if a living animal is put into the acoustic field?' Will it also be stably levitated?" researcher Wenjun Xie, a materials physicist at Northwestern Polytechnical University, told LiveScience.
Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.

Actually found a clip of magnetic levitation of a frog.

It's OK... That's Krugman's cat he's juggling. (from National Review Online's Krugman's Cat Economic Indicator.)
I thought it was L. Ron Herbert.
Bwahaha! You got me...
OK, kids... now we're going to use sound waves to rupture the internal organs of disgustingly obese, homosexual war barons. Be sure to get your Quidzach Hadarach's (sp???) permission, first!
Weirdo!
>> (1) Isn't Osmium the densest solid, not Iridium?
(2) What's "The Brown Note"? (It has ominous, or perhaps just messy, connotations.) <<
No. You owe the oracle a copy of Donnie and Marie Osmium's "Brown Album."
Maybe Don was Frank's less successful brother.
(Yes, Osmium actually is more dense.)
I vaguely recall doing that. Seems like it required some specialized apparatus though. A black-light, a strobe, lots of blue smoke...
Don Herbert was Mr. Wizard.
The Brown Note is a subsonic frequency reputed to cause the bowels to loosen uncontrollably. A device emitting significant energy at that frequency would make an interesting riot control device.
Brown Note = Myth Busted
I think mythbusters took on the brown note myth and busted it.
I regret to learn that ... I even more regret not having seen Adam, Jamie, and the crew put that one to the test.
"...although the fish did not fare as well, due to the inadequate water supply, the scientists report." Those whacky scientists.
What?
I didn't know that, but I had a feeling that's what it was.
"The Brown Note is a subsonic frequency reputed to cause the bowels to loosen uncontrollably. A device emitting significant energy at that frequency would make an interesting riot control device."
Or used strategically against entire cities. We gotta unbust this thing.
