This is a craptastic contest and the prize is the scene you just won with in return.

The name of this contest is even wrong; the water isn't pressureized It just simply has lots of energy as it is traveling at high speed.

the name is correct. the water is pressurized. otherwise there wouldn't be a jet at all ;)
don't you wonder why it has got a lot of kinetic energy? it's because of the pressure that forces the water to accelerate.

Are you sure? I thought the water was held in a tank with compressed air, thus being forced out by the air. Its the air thats pressuized. It takes a lot of energy to pressurized a fluid, thats why the use it in hydralic rams.

compression and pressure are not the same.
pressure is the force that acts orthogonal on a specific area
compression is the loss of volume due to compression stress (=> pressure).

the compressed air acts on the water and transmitts it's pressure to it which is forced to get out of the tank. and yeah fluids are used in hydraulics because they can transmit pressure very well without being compressed.
but even fluids can theoretically be compressed a bit but practically one can say they don't get compressed because there is only veeeery little compression. water only looses 3,5% of it's volume with a pressure of 1,100 bar (that's about 16,000 psi). oil is even less compressable.
