What are non-newtonian fluids?

A non-Newtonian fluid is like playdough, it can be squishy and flowy, but also firm and strong, depending on how you touch it.

Imagine you have a cup of goop that looks like soup. If you gently stir it, it flows like water. But if you suddenly punch it or slap it hard, it acts more like a solid, almost like it’s defending itself!

Normal fluids, like water or oil, behave the same way no matter how fast you move them. They are Newtonian fluids, named after a smart man called Isaac Newton.

But non-Newtonian fluids are different. They change their behavior based on how much force is applied to them, kind of like how your favorite jelly behaves when you press it with your finger or when you squish it in your hand.

A real-life example is ketchup. When you shake the bottle, it flows easily, but when it’s still inside the bottle, it feels thick and almost solid, just like a non-Newtonian fluid!
