I didn't know "sine" wave tuned to certain frequency can have such "awesome" effect on the water...Now that's a sight in dun see everyday. :P

ps: if you look carefully...the "vibration" of the hose is causing such a water pattern...not the water "itself".

I actually did some experiment with water and a subwoofer for an advertisement the other day, based on this experiment

I'll post some of the footage later when I get time to upload to youtube.


Did some other frequency related things too with salt and a metal plate bolted to a speaker

I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

Life is short! Enjoy the music while it plays, when it stops, there might be a chair for you...or  maybe not.

The subwoofer one...filmed at 25fps with a sine wave at 24-26Hz 24 makes it go down, and 26 makes it go up with 25hz freezing the motion. Very fun this was to replicate. Sub was a sunfire true subwoofer driven by minidsp power ice 125w in btl mode.

This used the same amp but an Emotiva 4" speaker driver in free air with an aluminum plate on a metal standoff with several fixed frequency tones that generated good standing wave patters. Again was fun to recreate this effect.
