Three-Dimensional Mid-Air Acoustic Manipulation: Acoustic Levitation

[Kruppy]

I just stumbled upon this and thought it was pretty cool.

Watch the video, different objects/particles are trapped in standing wave nodes and levitated.

Awesome, that is so cool!! I wonder what kind of acoustic energy level is needed to achieve the levitaion with those select objects.

I'm going to experiment in my microwave and see if I can get a few green peas to float!

The frequency is high enough that we cannot hear it no matter what the level...but I bet some nearby high frequency sensitive animals are no longer the same...!!

Tahnks for sharing that Kruppy!

Science catches up to legend?

Tibetan Monks levitate stones by using an acoustic levitation technique with the aid of drams in this 1939 sketch by Swedish aircraft designer Henry Kjellson.
