John Tindall Levitates with Microgravity Chamber

John Tindall demonstrates a Helmholtz Resonance Chamber where standing sound waves are used to levitate a foam cup. Three speakers emit a 600 hertz tone through wave guides controlling the x - y & z positions within the chamber.

Very nice! What is the theoretical limit of mass that 3 600hertz tones can lift?

@doughauf There pretty common-place in a lot OE stock vehicle exhaust systems. (Although they wont make cups levitate)

The areoturbine muffler used a helmholtz chamber design.

@originaldriver Where can you get a muffler like this????

[doughauf]

Is this how the correl rock castles where built.

[drdeak]

Dr. Deak did it first.

How about Modulate sound to dance to muis, or talking

lol!!!  very intersting

Cool... Its the helmholz effect.

The same priciple is used in accustic cancellation style car mufflers. Awsome stuff

Awesome! I cannot believe these amazing things you create - absolutely incredible! You rock!
