Looks like it's moving in slow motion. Then it looks like it's moving backwards. Then it looks normal. Awesome natural fx. :D

Yeah, nice ILLUSION!

The explanation: a camera shooting at 24fps. Play a sine wave of 24Hz to get static water, 23Hz to get it flowing backward, 25Hz to get if flowing slowly forward.

Nb: The water ALWAYS flowing down, you don't cheat with gravity (at least not with a subwoofer). This is just an illusion (the same thing happen with the weels of a car on the TV).

Too bad our eyes/brain don't see at a fixed frequency. You could really mess with people!
