Non newtonian fluids are fluids in which viscosity changes with applied force. To illustrate, let’s examine how this is differentiated from a Newtonian fluid. In a newtonian fluid, if an object is placed in to a fluid, the fluid will coalesce around the object no matter the force. In a non-newtonian fluid, the fluid will become more viscous in response to the larger force. In fact, the particles of the system behave more like a solid. Some other Non-newtonian fluids have the reverse effect, with a larger force producing a lower viscosity. An example of the most strange effects of a non-newtonian fluid is corn starch. When one pours corn starch, it flows in a very smooth manner. However, if one attempts to hit the Cornstarch with a mallet, it acts almost as it is a solid. You can even jump up and down on the corn starch!!!
