Reverse
Waterfall

Water drops defying gravity

What is it about?

We perceive the world selectively and rely on our expectations. We are accustomed to a world of repeating experiences. This upward flowing waterfall counteracts our intuition and questions our perception.

The illusion is created by a stroboscope which is tuned to a slightly different frequency relative to a series of loudspeakers. Single water droplets fall out of nozzles attached to the loudspeakers and seem to be flowing upwards in the light of the stroboscope.

Details and Theory

We rely on our intuition more than we realize. How often do we stop to question if what we just witnessed really did happen?

It could have just as well been an illusion or a misunderstanding.
When was the last time you didn’t trust your eyes? When was the last time you questioned reality?
