Video: Sound waves used for optical illusion with water.

By running a hose past a speaker set to frequencies of 23 - 25Hz, the water appears to slow down, stop, or move in reverse. The effect is only visible when recorded at 24fps.

Check out the YouTube details for details on how to recreate this at home.
