WATCH: Scientists Suspend Objects in Midair with Sound Waves

And move them around like tiny UFOs

No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair.

NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through opposing sound waves.

Video footage shows four speakers arranged around a square platform. The speakers emit supersonic sound waves, undetectable to human ears. They converge with such a powerful vibrating force at the center of the table, that they can lift drops of water and small beads into the air and guide them around like tiny UFOs.

Scientists think the levitation technique could herald a new method of moving objects remotely.

they have been doing this on a small scale for  a long time. nothing new.

I've read about it in the book "Dune". How nice...

It seems reasonable instead of projecting the sound inward toward the center, you could project it outward from there and create some type of equal but opposite force and still achieve levitation.  This could be the basis of a new form of propulsion.  I think I once read in some UFO related material, a theory that UFOs rely on riding gravity waves to get around.  I don't know if there's any real science behind that idea, but it seems related to this technique.

Dan -  Just so people aren't confused - that's "ultrasonic" which means above the range of human hearing, not "supersonic" which means faster than the speed of sound.

That's how the pyramid's were built.  Ketchup.
