We use many different substances in our everyday lives that are considered non-Newtonian fluids. These fluids have a special property where their viscosity (thickness) changes when they are put under pressure. To demonstrate this, we can use toothpaste. If we turn a tube of toothpaste upside down, it won't flow out naturally. This is because of the viscous forces that keep it in the tube. However, when we squeeze the tube, the toothpaste suddenly pops out. This shows us that the toothpaste is a non-Newtonian fluid that responds to pressure.
Basically, non-Newtonian fluids are fluids that don't follow Newton's law of viscosity. These fluids are usually complex mixtures, like slurries, pastes, gels, and polymer solutions. They can either show time-dependent or time-independent behaviors. Bingham plastic, pseudo plastic, dilatant fluids are time-independent, while thixotropic fluids and rheopectic fluids are time-dependent.
In this type of fluid, the amount of shear stress is not related to how quickly the fluid is moving, except when the shear stress is very small. The thickness of the fluid is determined by how quickly it is moving. This is the opposite of what happens in a Newtonian fluid.
People have started using a special type of fluid called "D3O" to make cases and bags for laptops, phones, and MP3 players. This fluid is special because it is "non-Newtonian" which means it changes consistency depending on the pressure applied to it. It feels like a soft sherbet when touched. This material is being used in many other areas as well.
When you mix corn flour with water, it creates a special type of liquid called a non-Newtonian fluid. This liquid is thick enough that you can run on it, but if you try to stand on it, you will sink. To see an example of this, watch the video at the link provided.

The fluid must not be thick like honey or syrup; it must be able to flow easily.
