Drop of Propylene Glycol Levitating/distorting in an Ultrasonic Acoustic Field.

I was listening to the Project Camelot interview with Ralph Ring from 2007, and he mentioned an experiment he performed in the fifties where he levitated a ping pong ball using "28,000 cycles" sound (above the range of human hearing).
I couldn't find footage of Ring's original experiment, which someone had allegedly replicated in the 1980's, but I did find these, using 30mhz(!). Real tasty.



Videos were acquired in the fluids laboratory of Dr. John R. Saylor, Dept. Mechanical Engineering, Clemson University.
