Water doesn’t actually compress much. If you put it under enough pressure, eventually it will become a solid.

We can but not alot, as it requires alot of energy.. we know that solid water/ice is less dense (it floats) and take up more space than liquid water as is a more ordered structure. So if we compress water it wont turn into a solid, it may just take up a little less volume.

If you keep increasing the pressure water will soldifiy – not from getting colder, but from increased pressure. This would be a different kind of ice than what we’re used to. I am told that there are several different phases of solid water, with phase boundaries between them just as there are phase boundaries between solid and liquid phases, or liquid and gas phases, etc.
eventually compression of water can form a black hole right?

Hi Juliet! Neat question!
Water is a pretty amazing substance. If you keep it at a constant temperature you can actually take ice and compress it and get liquid water! Application of further pressure it will solidify again, just do to the increased pressure! This solid however would not be the ice we are used to. The structure would be different do to all that pressure! Eventually if you kept increasing the pressure, the water would undergo fusion! Compress it further and it would form electron degenerate matter (like a white dwarf star), even further it would make neutron star material (so dense that the electrons are compressed into the protons and only neutrons remain!). Any farther and you’d get to a black hole!! That would take an astronomical (literally!) amount of pressure!!
