The Slow Mo Guys demonstrate what happens when you film cool water spirals in slow motion at a rate of 1600fps. They used some water logged foam balls to demonstrate the spirals that occur but that can be seen in real time with the good old Mark One Eyeball. The advancement of camera and video technology is allowing us to see all sorts of things in slow motion. If you enjoyed this cool video you might also like to see this clip of events filmed in Super Slow Motion.
