MeFi post: spooky fluids!

Anyway, my theory is that it has to do with mini-vortices being spun off the central one -- you can see them forming in one of the side views. When two, three, four, etc of these mini-vortices occur at once, they migrate outwardly at the same speed from their common experience of centrifigal force (thus producing symmetry), each mini-vortex forming a (rounded in every case!) corner of the polygon. Tornadoes do a similiar thing -- spawning mini-vortices, that is.... [more]
