As far as I can observe, while the ball is spinning, the water at the top is stationary relative to the balls surface.
I was so worried about the whole flat-earth theory that I went and visited the granite-ball-thingy in the Perth CBD today. I can confirm that it is covered by water, and somehow magically it is all over it. Even on the top. If it were running to the bottom, it was too slow to be perceived, so I would say it wasn't.
Whether it was moving with the ball or not, I cannot say.
I really expected to see PM33 there taking photos and marvelling at the wonders of science, but no, I am pretty sure he wasn't.
I have to say I have walked past this thing heaps of times and never even taken any notice of it. Now I know it is planted by the Illuminati as an 'up yours' to the people that think they are in charge.
