I was spining my full water bottle before and watched the air bubble move from from the top towards the centre of the bottle, it was spinning sideways. Got me thinking if you had a sphere with say 70% water 30% and set the outside spinning at whatever the optimum speed would be, you'd get your nice little airbubble forming in the middle in a spherical shape(?)

Ok that in mind lets now say you suspended a platform in that area with wires or such like, got it nice and stabilised. Couldn't you stick a person in there they could wander around and do whatever..well until the oxygen ran out I guess. It's completely pointless yes but I just thought it would be pretty cool. Sound possible?
Ooh there's a thought just imagine if you slipped off the edge of the platform...that could make for an interesting ride!

Presumably the sphere would need to spin in 2 dimensions (circularly and end-over-end) to keep the air bubble in the middle, otherwise it would float to the top.
