NON-NEWTONIAN FLUID

A non-Newtonian fluid is a fluid with properties that are different in any way from those of Newtonian fluids. Most commonly, the viscosity (the measure of a fluid's ability to resist gradual deformation by shear or tensile stresses) of non-Newtonian fluids is dependent on shear rate or shear rate history. Some non-Newtonian fluids with shear-independent viscosity, however, still exhibit normal stress-differences or other non-Newtonian behavior. Many salt solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as ketchup,  custard, toothpaste, starch suspensions, maizena, paint, blood, and shampoo.

Preparing  a Non-Newtonian Fluid.

1. Pour approximately 1/4 of the box of cornstarch into the mixing bowl and slowly add about 1/2 cup of water. ...
2. Continue adding cornstarch and water in small amounts until you get a mixture that has the consistency of honey.It may take a little work to get the consistency just right, but you will eventually end up mixing one box of cornstarch with roughly 1 to 2 cups of water. Notice that the mixture gets thicker or more viscous as you add more cornstarch
