===Shear thinning fluid===
[[File:Painting with non-newtonian fluid.jpg|left|thumb|Paint is a non-Newtonian fluid. A flat surface covered with white paint is oriented vertically (before taking the picture the flat surface was horizontal, placed on a table). The fluid starts dripping down the surface but, because of its non-Newtonian nature, it is subjected to stress due to the [[gravitational acceleration]]. Therefore, instead of slipping along the surface, it forms very large and very dense droplets with limited dripping.]]

A familiar example of the opposite, a [[Shear thinning|shear thinning fluid]], or pseudoplastic fluid, is wall [[paint]]: The paint should flow readily off the brush when it is being applied to a surface but not drip excessively. Note that all [[Thixotropy|thixotropic]] fluids are extremely shear thinning, but they are significantly time dependent, whereas the colloidal "shear thinning" fluids respond instantaneously to changes in shear rate. Thus, to avoid confusion, the latter classification is more clearly termed pseudoplastic.

Another example of a shear thinning fluid is blood. This application is highly favoured within the body, as it allows the viscosity of blood to decrease with increased shear strain rate.
