Acoustic Levitation

Acoustic Levitation of a float assembly with a sphere and a magnet in a magnetic field.
The levitation is not vertically against gravity but horizontally against a rather weak magnetic field to keep the acoustic field intensity low.
The magnetic force is in the range of 100µN.

Nice! Levitating metal plates vertically by "sonolevitation" works too: bit . ly / 8UJ9QE

Acoustic levitation of a gold leaf is an ideal combination, I should try that as well. I was just afraid to spend to much effort in increasing the power with the result to just ruin my ears.

i guess above 20 000 hz is it :)?

[manf1234]

it is 40kHz, the cheap ulrasonic transducer.

All we need to do now is figure out a way to diract it into specific directions, there for giving us the step forward into the future we need.

simple physics... sound waves strong enough to move physical objects...great idea... now make it bigger and amplify the output... lets see what we can move with it...

That is called CYMATICS

Rearrange matter with sound vibrations...

This video is different, but it comes down to the same thing, maybe even better.

However this has been known for a very long time, only the knowledge has been surpressed for the mainstream public, obviously...

Because who is going to pay for energy when it is extraordinary cheap or even for free... The BIG Company's don't like this at all... That is why we have to use internet for spreading the word, but beware a lot disinfo !

So?

That's floating on water!
