non-Newtonian fluid

Cornstarch-water mixture type

A non-Newtonian fluid is a liquid whose viscosity changes under stress or pressure.

Unlike water or oil, which flow consistently, non-Newtonian fluids may thicken when stirred quickly (like cornstarch in water) or thin when agitated (like ketchup).

The term contrasts with Newtonian fluids, which behave according to Newton's laws of viscosity.
