I think if it like a snow globe, occasionally the snow falls into patterns you don't like, there is an abundant body of science that covers principles of physics that dictate how the snow moves. You might be able to come up with some broad patterns that show what lead to outcomes that you don't want. Nevertheless the best option for fixing the undesirable pattern of snow is to give the globe a quick shake. Solutions do not necessarily require a complete understanding of the problem, or even directly target the problem. Now if you only wanted to move a few problematic flakes without shifting any others, that's a different, much harder problem.
