What would it be like to swim, in space?

Imagine NASA decided that the astronauts on the ISS needed more recreation options and decided to add a swimming pool (forget the logistics of how this is done). The new swimming pool pod would be a large open space with a giant "bubble" of water floating in the middle of it. If an astronaut were to swim in to it, would they be able to escape it? Or, would the surface tension of the water and lack of gravity make drowning extremely likely?

The bubble of water would not stay as a single bubble, especially once people started trying to swim in it.  You'd end up with a compartment full of floating blobs of water of varying sizes.  You'd have to be careful to avoid inhaling water, or you could drown.

A more practical swimming experience in space would be to fill a compartment entirely with water, and use breathing apparatus when inside.  Now, you'd be able to actually swim, because there'd always be water to push against.
