Acoustic Levitation Works On Small Animals
anthemaniac writes "Researchers for at least two decades have used acoustic levitation to suspend light materials without a container. Wenjun Xie, a materials physicist at Northwestern Polytechnical University in China, has previously used ultrasound fields to levitate globs of iridium and mercury, very heavy materials. Now the scientist has performed the feat with live animals. From the story: '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.' Apparently the ants, spiders and ladybugs endured the trick just fine, but the fish didn't do so well due to lack of water."
It's even easier to get fish to levitate in water if you never feed them.

Come on. A spider ISN'T an aminal. (sic)

I was once lay on the bed and my cat decided to curl up in the small of my back.
When I let out a ripper of a fart I swear he hovered right there for about 15 seconds.
(Incidentally, after that event he never lay on my back again)

One stick of dynamite does the job a lot quicker.

I'll have you know that none of those animals were small. The System Reference Document doesn't list them, but I'm confident they'd be identified as "diminutive," or smaller still.

No, he's right. Spiders are not aminals.
Now it's levitating spiders? I am so screwed.

As God is my witness, I thought turkeys could fly.
I'm just walking along, minding my own ant business, and all of sudden some jackass decides to levitate me. Oh, that's right, it's so funny to pick on the ants. Everyone picks on the ants. We're just trying to make a living and feed the queen...she gets to drink nectar. Think the rest of us get any nectar? Not us worker ants. You try running around blind trying to follow a scent trail during allergy season. We get stepped on, eaten by other bugs and birds...don't get me started. And then there's the nursery, those ingrates never get enough. Like it's not bad enough putting up with their crap along comes to the dominant species and thinks it's just SO funny to levitate us. Suppose I should be glad they didn't roast us under a magnifying glass like the neighbor kid. Little delinquent. I'll be he grows up to be a career criminal. It's all so meaningless.

This is absolutely true; I can provide photos (or you can come see for yourself)
The defunct business next door to my house has signs saying "$500 reward leading to the arrest and conviction of persons destroying this property." There was what looked like a very weatherbeaten, unmaintained house and a large tin structure that looked like it too had not been maintained in years; gutters falling, etc.
Then last March 12th two F2 tornados tore through here. It ripped the hell out of both structures (again, I took pictures). The structures were subsequently razed.
So if you can find God and get him in court, $500 is yours for the taking!

An aminal is a type of chemical compound that has two amine groups attached to the same carbon atom. Small aminals would have small amine groups attached to a regular-size carbon atom.
Man, you really need that seminar!
Interestingly, after levitating for several moments, all subjects were found to be deaf to ultrasound.
