Detailed explanation-1: -A new model predicts how cornstarch and water, a non-Newtonian fluid, can behave like a solid or liquid, depending on how fast it’s deformed. When swirled slowly in a glass, the mixture acts as a liquid.

Detailed explanation-2: -Ketchup, for example, becomes runnier when shaken and is thus a non-Newtonian fluid. Many salt solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as custard, toothpaste, starch suspensions, corn starch, paint, blood, melted butter, and shampoo.

Detailed explanation-3: -Is water considered a non-Newtonian fluid? A Newtonian fluid is one whose viscosity is unaffected by shear rate: when all other factors are equal, flow speeds and shear rates have no effect on viscosity. Newtonian fluids include air and water. As a result, water isn’t a non-Newtonian fluid.

Detailed explanation-4: -Quicksand is a non-Newtonian fluid that acts more like your Ooze–it gets more viscous when you apply a shearing force. If you ever find yourself sinking in a pool of quicksand (or a vat of cornstarch and water), try swimming toward the shore very slowly.

Detailed explanation-5: -Simple ingredients for making non-Newtonian fluids: cornstarch and water! In a bowl, mix one 2 lb box of cornstarch found in the baking aisle of the grocery store and 2 cups of water. TIP: Mixing by hand is much easier. It is messy and slow going.
