It’s fitting that the LeviZen looks like a strange piece of audio gear because it essentially is one. To make water levitate, it blasts opposing ultrasonic waves back and forth so that they combine into a standing wave, which has points that remain perfectly still. By placing water at those points (known as “nodes”), the droplets are able to hover in the air because they’re caught between equal and steady forces. The sound is ultrasonic, so you won’t be able to hear it, though your pets might, so that’s something to be wary of… More at The Verge.
