Kinda cool that just sound waves can actually lift stuff and hold it suspended.

It might have worked even better if the driver circuit had been of the pushpull veriety rather than single ended.

I've heard of old car amplifiers being used for this, with a slight change they can go well over 30 kHz and not lose much power.
