Detailed explanation-1: -An inexpensive, non-toxic example of a non-Newtonian fluid is a suspension of starch (e.g., cornstarch/cornflour) in water, sometimes called “oobleck", “ooze", or “magic mud” (1 part of water to 1.5–2 parts of corn starch). The name “oobleck” is derived from the Dr. Seuss book Bartholomew and the Oobleck.

Detailed explanation-2: -Oobleck is a suspension of cornstarch particles dispersed in liquid water. This non-Newtonian fluid defies Isaac Newton’s law of viscosity, which states that fluid can be changed only by changing the fluid’s temperature. For example, you can make honey thinner if you heat it but not by adding pressure or force.

Detailed explanation-3: -For example, water freezes and turns into a solid at 0˚C and turns into a gas at 100˚C. Within this temperature range, water behaves like a ‘normal’ liquid with constant viscosity. A cornflour and water mixture – is a non-Newtonian fluid. Typically, liquids take on the shape of the container they are poured into.

Detailed explanation-4: -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.
