Viscosity is a measure of the resistance of a fluid to flow (usually through a specific orifice). Materials that are gel-like at rest but fluid when agititated are described as thixotropic. Centipoise is the unit of measure for viscosity, where 1 centipoise is the equivalent to the viscosity of water.
