What Happens When Water Meets a Black Hole?

What would happen if you surrounded a black hole with water?

the water would fall into the black hole

OK, little bit of background here, I thought it would! I was having a discussion with a friend who was talking about how water is incomprehensible, so if you surrounded a black hole with water only some of it would be sucked in. I decided to seek the internet's advice. Sorry but I do not have a super in depth knowledge of this area so I apologize for any mistakes I make. Thanks!

I assume that rather than incomprehensible, you mean non-compressible, since water isn't all that hard to understand You are thinking of pressures like those found in normal objects such as Earth. Black holes aren't like that.

Much appreciated. So water would behave differently in the environment of a black hole?

EVERYTHING behaves differently in a black hole.

Also, if you compress water "hard" enough, you will get ice (even at room temperature).

This still is talking about the kind of pressure that exists on Earth or that can be made by man. This simply is not comparable to a black hole.

Water is much more compressible than many solids. So there is nothing special about considering water instead of rocks or pieces of metal.
There is no known material which is "in-compressible". Starting from a wrong premise, the question does not have substance.

I don't see why even assuming the water is incompressible means anything to the question. If it is a ring of water in orbit, it [boils, freezes, sublimates and] orbits the black hole. A non-rotating sphere of water, it [boils, freezes, sublimates and] falls into the black hole. Is getting crushed really what the OP is about?

Cool, thanks guys!
