As mcgregor mentioned, you can't compress water like you can compress air.

If air is pressurized in a container, it compresses. When the container breaks, the air decompresses rapidly, releasing a bunch of energy (like the sound of a balloon popping). That energy also sends stuff flying, and that's what hurts you.

When water is pressurized in a container, it just pushes out on the walls without storing the energy itself. When the walls break, they still can go flying from the force that the water was pushing on them, but the water doesn't add to the mix by rapidly releasing energy to give the walls an extra boost.

Take two empty soda bottles. Fill one with water and leave the other empty. Make sure both caps are on tight, and run over both of them with your car. See which one has the more violent failure.
