I like this part particularly:
"stevendaryl You don't need anything attracting the water to the bucket. What you do need is a way to get the water in the bucket spinning. So, for example, if you put a lid on the bucket, then spin it, the water will be forced to the bottom of the bucket. At that point, you can take the lid off, and the water will stay in the bottom as long as you keep spinning the bucket.
If you take a bucket of water into absolute zero gravity than the first thing the water would do is form a sphere, what you are saying is if you compress the water into the bucket then the water under pressure will stick to its side. I agree you have a volume of liquid under pressure forced inside the container, however that doesn't translate to a human in air standing on the wall of the cylinder. There is no force or pressure pushing back human against the cylinder wall. You're certainly right that if there is nothing to keep the water in the bucket initially, then it will just float away. So, yes, if you have giant cylindrical space station that is spinning, then it is possible to float forever at the center of the cylinder. You won't be pushed to the walls of the cylinder. However, if you do move in the direction of one of the walls, you will eventually hit the wall. At that point, friction will soon get you moving at the same speed as the walls. When you are moving at the same speed as the walls, you will "feel" an apparent gravitational force pushing you against the wall."

I guess, hypothetically you could jump with enough force to drastically change your velocity/trajectory (from the wall/floor you are now spinning with, quite quickly) but that would probably be the equivalent of jumping yourself into orbit, depending on how quickly the cylinder/starport was spinning.
