I built an acoustic LEVITATOR! Making liquid float on air

Haha what a coincidence! We JUST finished building one this semester based off of Marzo's design!
We got horizontal and vertical translation in the bowl design and levitated water, and graphite and a bunch of other stuff. Here's a short video I put up.

If you ever get liquids working TRY SOAPY WATER, it's sooooooooooooooo cool! Repping Derek Muller's undergrad program! #QueensEngPhys
