Scientists Use Sound Waves To Levitate, Move Objects
sciencehabit writes "The tragic opera Rigoletto may move you to tears, but here's a more literal application of the moving power of sound. Sound waves with frequencies just above human hearing can levitate tiny particles and liquid droplets and even move them around, a team of engineers has demonstrated. The advance could open up new ways to handle delicate materials or mix pharmaceuticals."
Just for the record all Opera moves me tears, what the fuck is up with the middle school rhetorical flourish?
Also this is basically decades old. How much is /. getting for the clicks?

A whole new way to enjoy your beverages. Beats some of the other methods.
Acoustic levitation is nothing new, what they've done is found a way to move stuff around while it's levitating.

Can the bottom of my car be a flat surface which vibrates sprayed water droplets, thus slightly levitating the vehicle and allowing forward movement via those particles?
Sand on a 15" speaker, an amp, and a signal generator was a fixture of Hamfests in the 70's.
Ever notice how sliding a desk across a floor is really heard to do, then gets easier?
It's because it's levitating part of the mass on trapped sound waves under the sliding feet...
This is old news by now.

Back in the 1990s I heard the use of sound waves to move objects proposed as one of the fringe theories for how the pyramids were built, because "people could not have moved those great big blocks such long distances!". So, there must have been earlier work by scientists in moving things with sound waves that crank historians could twist for their own theories.
Sound doesnt move anything, however the air it touches does, so why not skip the sound part and use air jets ?

More than a YEAR ago they were levitating BOWLING BALLS with sound waves.
I'd be curious to see what's the most absurd technology you can come up with that's nothing but hype but geeks will defend to the death. Tell 'em Elon Musk is backing it too. In space. Let's see, "private air jets used to 3D print in space". Absurd enough?

Schroedinger's Brexit: The UK is both in and out of the EU at the same time!
Frankly while this has the potential to be interesting as long as it is being fed to us by elitists who watch obscure operas and attend ivy-league schools I am not interested. This is a yet another example of the neutrality of science being corrupted and used as a tool to support the cultural agenda of the upper class.

Some people might think this sort of discovery will vindicate claims made by dubious inventors like Keely. Be on the look out for anyone here mentioning "vibratory sympathy".

The sound levitated the cat about 2'.
I eat only the real part of complex carbohydrates.
Just play any, for example, Justin Bieber tune and the resulting sound waves instantly move me out of the room. Most commercials on TV work the same way, unless I'm in control of the remote.
Once I was a four stone apology. Now I am two separate gorillas.
When will they turn screws using sound?
Many sounds make things move, for example, the sound of my wife reminding me of chores usually gets me moving pretty swiftly.
...even be able to image human foetuses.
Sorry -- just thinking out loud.
Could this be the technology behind The Doctor's sonic screwdriver?
Let us examine how we can create a space ship like in sci-fi alien movies using the latest advancements in sound technology. Hello, I am Michio Kaku, I am a world-renowned theoretical astrophysicist and douchebag. I will take you down into a journey and see if this story is science fiction or science fact based from something that I personally believe.
This explains the sonic screwdriver --but i think you knew that
I yell at my kids "Get yer ass in gear!!" and they move like crazy!!!

Rolling Stones have being using sound to levitate various female undergarments to great effect.
You somehow seem to be confusing levitation with bouncing up and down against a surface. Something like Buzz Lightyear mixing up flying with falling...

But can it levitate a frog? http://www.youtube.com/watch?v=A1vyB-O5i6E

Animals, and humans with slightly below and above normal sensory ranges, are going to really hate the future. IR lights are all over the place: leakage from normal lights, security cameras, larger touch displays, Kinect and similar device projections, etc... Blue light is already messing with human's sleep patterns (look into N24 and DSPS. The best treatments so far is dark therapy, aka reducing blues) I wonder what all the IR at night is doing to the animals that can see it.
We already take advantage of high pitch noises to annoy dogs and hide sounds from adults. The current problems are from cheap quality hardware that puts out high pitch whines, which many adults don't hear, so they ignore you when you complain about whatever TV, projector, or device they're using. Judging from what I heard as a kid, I have to assume animals are hearing constant noise from our devices. As we start expanding the use of sound for DIY radar and moving things, I have to wonder if we're going to start to drive them crazy and provoke more human attacks.
And here I was worried the new owners wouldn't understand the readership when DICE bought /.
Between this and the whole beatboxing story I saw earlier is science now coming down to either doing a study on things we all know about, or stating the obvious?
This sounds like someone watched an episode of big bang theory, liked the idea on the show and then decided to turn it into a research project.
...FUS DO RAH!!
Mages, er...'scientists' of Skyrim have known this for millennia.

of when I use my "these aren't the droids you're looking for" sound/hand wave to levitate flies. They shoot straight off. Unfortunately, flies have a very short memory, and two seconds later they're back for more. Definitely too short to be stormtroopers, flies.
Who cares? $800 dollar Honda Civics have been doing this with $2500 dollar strereo systems in my neighborhood for years!
The paper was submitted on January this year, and approved for publication on June 8. This is a change in design that allows transport and handling rather than just levitating it in air. The flourish was in the original article BTW.
