Water compressibility allows water fountains to spray water.

Large water fountain in Seattle, with kids playing all around it.

Detailed Description

Water Compressibility

One property of water is that it is not compressible--you can't press on it and have it shrink much at all in volume. Just fill a balloon very full with water and then really squeeze it (to compress the water). Instead of the balloon shrinking in size you will end up taking a bath. 

Being incompressible, water makes a handy and useful tool for people to do work (and have fun). Water incompressibility allows fire hoses to work, makes hydraulically-driven tools to function, and for kids to have fun running underneath a fountain that shoots out water (under pressure).
