Title: Smooths ball addition/removal

The parameters (5500, 7000) aren't exactly right, but something like this might give a better demo on mobile. It adds a bit more inertia w.r.t. adding and removing balls, and removes older balls instead of newer ones to avoid removing a ball that was just added.
