Consider the concept of these videos http://www.youtube.com/watch?v=Zip9ft1PgV0&sns=em and http://www.youtube.com/watch?v=cUhgKFV5Ri4&sns=em but set in a zero gravity environment and in a fully encapsulated and high pressure container. My questions are as follows: What shapes will the water conform to at increasing speeds? Will the water conform to a parabola and then ultimately a hollow cylinder as it does on earth?

Is it possible that without an opening to spit and by continuously adding more water to the centrifuge, that the water could ultimately fold in on itself and conform to various states of torus, by creating vortices within itself?

[Edit] Also, taking into account 0G, will the water even conform to its bounding container in a manner in which it receives traction and can be spun?

The parabolic shape is due to gravity. Without it, you'd have a much more boring cylindrical shape.

But even with gravity, given higher speeds, it takes a cylindrical shape, not so? – Dorian Lyder Sep 15 '12 at 6:48
@DorianLyder In the limit that the centrifugal force greatly exceeds gravity, yes. You make the approximation of imagining gravity doesn't exist. – poorsod Sep 17 '12 at 10:01
