Is There a General Mechanism Behind the Chaos?

Eris: The basic mechanism that generated it is very basic. Repeated rolling and stretching and compression. And yet, after a small number of these operations, these moves, the butter could be essentially anywhere in the universe. That's pretty chaotic. But if you just are a little bit sloppy and how you roll in that third direction, that'll also get mixed up. A little hyperbalicity goes a long way to produce mixing and other kind of chaotic behaviors.
