Water Falls?

Toss some water on a hot surface and the water will sizzle and evaporate. Toss it on a VERY hot surface and some of the water will evaporate and create a vapor-cushion on which the remaining water droplet will ride and move around the hot surface.

Okay that’s pretty basic and established so you ask, “What’s so Wohba about that?”

Now make the surface a super hot brass saw-tooth ridged staircase and the vapor cushion will seek the easiest escape route —UP— along with its piggy backing water droplet!

Here is the movie.
