Revealing mistake: During the draining of the water in the dish, some shots show the water moving backwards. For instance, at a particular moment, masses of water jump up, arc toward the opening, and fall in it. The most likely reason is that, during the filming, the special effects people took a shot of a replica of the dish filling with water, then edited it the other way to show that the water was emptied from the dish.
