Non-Newtonian fluid

Hi there! Do you like playing with slime or gooey things? Well, some liquids can be like that too! These are called non-newtonian fluids, and they act very differently from normal fluids like water.

When you pour water, it flows at a constant rate, no matter how much force you use or how fast you pour it. That's because water is a normal fluid, and it follows a rule called Newton's Law of Viscosity. But non-newtonian fluids don't follow this rule!

Imagine you have a pot of honey. If you try to pour it quickly, it becomes thick and gloopy. That's because honey is a non-newtonian fluid. It reacts to force and pressure in a different way from water. When you apply force to it quickly, it resists and becomes thicker. But if you pour it slowly, it flows more smoothly because it has time to adjust.

Some other examples of non-newtonian fluids include ketchup, toothpaste, and quicksand! They all behave differently depending on how much force or pressure you apply to them. So next time you're playing with slime or goo, remember that some liquids can be like that too – they're called non-newtonian fluids!
