WebNon-Newtonian fluid. A non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress. In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. Ketchup, for example, becomes runnier when shaken and is thus a non-Newtonian fluid.

"WebMay 26, 2014 · Dilatant. Unlike rheopectic and thixotropic non-Newtonian fluids, those described as dilatant will change their viscosity dependent on how much force applied is, not how long for. The harder you hit a dilatant fluid the more viscous it becomes. One such example is Oobleck – a fluid similar to raw custard make of corn starch mixed with water. " - Examples of dilatant
