What is saturation?

Saturation is when something can’t hold any more of another thing, like a sponge that’s totally full of water.

Imagine you have a glass full of juice. You try to add more juice, but it just spills out because the glass is already as full as it can be. That's saturation, when the glass (or whatever container) is holding the most juice it possibly can.

Think about a sponge in the bathtub. When you squeeze it, water comes out. But if you keep adding more water to it, eventually it won’t be able to take any more, that’s when it's saturated. It’s like the sponge is saying, “I can't hold any more water!”

This idea works in lots of places, like when a cloud gets so full of raindrops that it starts raining, or when your shoes are completely soaked and won’t take any more water from the puddle.
