Fluid

A fluid is a collection of molecules that move freely about, take the form of the volume in which they are contained, and adhere to one another.  Fluids flow easily.  Examples of fluids would be water and gases.  Liquid based fluids do not compress well.  Gas based fluids compress a great deal.
