The strange physics of suspended fluids and inverse buoyancy
Buoyancy under a suspended liquid
The liquid can be suspended and boats can float upside down in this physical experiment that defies the force of gravity. Researchers in Paris studied the effect of vertical vibrations, which can be used to suspend a layer of liquid in the air. They discovered a strange phenomenon that allows lightweight objects to float on the underside of the liquid, a kind of inverse buoyancy. This counterintuitive behavior results from continuous vibrations that alter the forces acting on the floating objects.
