After watching a movie in which levitating water was used as an illusion, I was curious to discover how it works. Unfortunately I cannot find any great explanations of the science behind the effect, only that strobe lights are what cause it. I want to know why strobe lights cause this effect.
It is my assumption that there is a steady stream of water, and the strobe lights are flickering on and off at a certain rate. Why then do I not see the entire stream of water being lit up, rather than individual droplets? What causes the droplets to appear to "move?" And why are there dark spaces between the droplets when there is apparently water there?
