It seemed to me that the hose itself was moving thereby creating this exiting water pattern.




in the very first example, the hose did not move, yet there was a wave pattern in the water's flow.

In the second and third examples, it DID move, and I think it is the movement of the hose that created the spiral that simulated direction (up and down... like the illusion that a wagon wheel is going backwards at certain speeds)
