Zero gravity by sound waves

In a spacecraft, among the most efficient ways to transport and position uncontained gases, liquids and powders, is a phenomenon known as acoustic levitation. Below on Earth, the selfsame phenomenon creates the impression of a localized absence of gravity, enabling the airborne levitation of fluids and solid matter.  For this rendition of Sonolevitation, slivers of gold are acoustically suspended and spun in different directions at varying speeds.  The spin reveals the rotary consequences of sonic vibrations as well as the dynamics of frictionless motion.
