Thanks for sharing. Reading this made me think about Jupiter as a ball of fluid in a way I hadn't previously. Now I'm wondering why all of Jupiter's colors haven't mixed together.
It's not as extreme as oil and water, no. But it's correct that they don't mix as well. Especially if you consider volumes the size of jupiter. A layer of hydrogen gas (h2) will weigh less than a layer of oxygen(o2), so if they're at the same temperature then they will separate over time.
