Hello,

Could someone briefly explain the physics of that experiment?
Why an expanding water vortex?

Similar to Doc Edgerton's strobe experiments the video frame rate samples the falling water. I think its just for a cool looking effect.

Because the 24 frame rate matches the 24hz sine wave?

As long as the water wiggle frequency and the frame rate are the same, this should work. 24 FPS, 25 FPS, 30 FPS, 60 FPS all should work, but look different.
