Facebook user Brusspup performed a simple, but interesting, experiment. Passing a tube of water across the front of a loudspeaker yields a standing wave when tuned to a 24 hz sound wave. Then when switched to 23 hz, it appears that the water droplets are actually traveling backwards through the tube they just came out of. A camera recording at a standard 24 fps is playing tricks with the eye when the frequency of the sine wave is very similar.

[…] optical illusions, Facebook user Brusspup is busy turning water into waves. You may remember his similar experiment from this time last year, which he has now followed up with improved camera close-ups. […]
this concept would make a cool water fountain or shower for the rich to wow their rich friends.
