Could there be any truth in the use of acoustic levitation in the building of the pyramids? And how about frogs?
As academics we should get out there and tell the general public what we do and why. Science and society should be inexorably linked.
In orbit astronauts experience micro-gravity. Acoustic levitaion, pioneered by Taylor Wang and Eugene Trinh, can be used to hold solids and liquids in place to perform careful experiments.
