The Weird Physics Of Upside-down Buoyancy.

Is physics broken? — The researchers were able to validate their results with theoretical calculations as well, meaning that this event was not simply a fluke but instead a fundamental characteristic of how vibrations affect dense liquids. The researchers are excited about what other bizarre states like this might exist in the fields of chemistry or biology, they say in the paper. Discovering what anti-gravity could mean in these fields offers great potential for future research, write the authors.
In a "normal" environment (that is, one without extra vibrations) we would expect a highly viscous fluid like glycerol to slowly ooze down the sides of an inverted, air-filled chamber, and settle at the bottom, displacing air that had originally occupied the bottom of the chamber. But if the chamber is vibrating rapidly, the researchers found that viscous liquids never quite reached the bottom of the chamber — instead, they levitated above it on a cushion of air.

In their experiment, that team created two of these levitating liquids. Unlike the "normal" scenario in which gravity was the primary force controlling the movement of fluids in the chamber, in the vibration scenario, the levitating layers feel both downward pressure from gravity as well as an upward force from the pressured air they've created below them.
It's this push and pull of forces the scientists say is key to the anti-gravity effect.
