That levitating liquid, on the other hand, is the product of a non-magnetic technique called acoustic levitation. Align two loudspeakers vertically on top of each other, and when tuned up to the proper frequencies, they create a standing wave of sound between them. The sound waves from above and below cancel each other out, letting light objects just ride that sweet wave midair.
"Why do I suddenly want to play Pac-Man?"
Sadly, the minimum sound levels required for acoustic levitation are around 160 decibels, at a pitch that is as high as a dog whistle. Levitating bigger objects requires significantly louder sounds, so for now, the method is limited to floating lightweight stuff like water drops and toothpicks. Still, it's a beginning: All we need to do now is develop technology that enables us to withstand intense acoustic vibrations without instantly exploding in a mess of guts and shattered bone, and we'll finally be able to say goodbye to walking forever.
Meanwhile, here's a cool video of water and sodium locked in a levitating waltz:
