I've been thinking about one of those tables. I have a weird question. In the videos and descriptions I've read, everything says that the ball is rolling across/through the sand. And I can't tell if that's really true or not from any of the videos.

So, is the ball actually rolling? Or is it just being dragged through the sand without doing any rotation of its own? Can you tell the difference when watching it draw?

I suppose I was just wondering if one side of the ball ends up showing appreciable wear from the friction over time if it's being dragged, or if you're supposed to manually change the ball's Y-axis every now and again (flip it or anything). Not that that would be a big deal, of course.

Just curious about your experience with that.
