                           Flowing water, stationary
                                        
Brusspup filmed water going through a speaker running at 24Hz (Hertz) [1]
(link via Hacker News [2]) and the result is incredible—the water just sits
there, in mid-air. As he adjusts the sound wave, the water appears to move
slowly down, then reverses itself.

It is a trick, though it's not special effects—it's all done in real time
with a camera. But it's the camera that causes the effect—it's acting like a
strobe light, catching the action at just the right moment. And it's still
impressive though.
