What is fluidity?

Fluidity is when something can flow easily, just like water or syrup.

Imagine you have a glass of juice, that's a fluid, and it moves around inside the glass because it has fluidity. Now think about honey. It also flows, but it’s slower, it has less fluidity than juice.

If you pour juice into a cup, it goes down smoothly, like when you slide off the couch. That's fluidity in action! But if you try to pour syrup, it takes more time and effort, it's still fluid, but not as fluidy as juice.

Think of your favorite cereal, when you pour milk over it, the milk flows right through the pieces. That’s because milk has good fluidity, making it easy to mix with the cereal.

But if you tried to pour syrup on your cereal, it would take longer for it to cover everything, that's because syrup is thicker and has less fluidity than milk.

So, fluidity helps things move around easily, just like how juice moves inside a glass!
