This is an amazing water and sound experiment you can try at home. Tape a vinyl hose to a speaker, run water through it, produce a 24 Hz sine wave, and turn up the volume. Your brain's (eye's) frequency is much higher than that of a camera, so you must use a 24 FPS camera in order to see this stroboscopic effect. The water appears to be frozen in time. If you increase the frequency you get a slow motion forward effect. Decrease the frequency for a slow motion reverse effect. I used an amplified 12" infinity kappa at 700 watts.

All you'll need is:
12" speaker
Clear vinyl hose
Sine wave generating software (23, 24, and 25 Hz)
Duct tape
A camera that is capable of filming in 24 frames per second
