Viscosity is a measure of the resistance of a fluid to deformation under shear stress.
It is commonly perceived as "thickness", or resistance to pouring.
Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction.
Thus, water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity.
