What are pumps?

A pump is like a helper that moves things from one place to another, just like how you help move toys from your toy box to the floor.

Imagine you have a water bottle, and you want to pour the water into a bigger container. You might tip the bottle or use a straw. A pump works in a similar way, it helps push or pull things so they can move through tubes or pipes.

Think of your favorite juice box. When you squeeze it, the juice comes out because you're pushing on it. A pump does something like that, but for bigger things, like water in a hose or air in a bicycle tire.

Some pumps push things forward, like when you use a hand pump to fill up a balloon, you press down, and the air goes in. Other pumps pull things from one place to another, like when you suck on a straw to get your juice.

Pumps can be big, like those that help water go through a whole city, or small, like the ones inside your bicycle or vacuum cleaner. They're just helpers, simple but very useful!
