A tube is like a long, hollow straw. You know how you drink juice through a straw? A tube works in a similar way, but it can be much bigger or smaller. It lets things like water, air, or even toys move from one end to the other. Imagine it like a secret tunnel just for things to travel through!

Think of a tube as a magic pathway. When you blow into one end, your breath travels all the way to the other side. It’s like sending a whisper through a secret passageway. Tubes can be made of plastic, metal, or even rubber, and they can be used to carry all sorts of things, not just air.

A tube can also be like a long, squishy snake. When you squeeze one end, the stuff inside moves to the other end, just like when you squeeze toothpaste out of its tube. This makes tubes very useful for getting things from one place to another without making a mess. So, a tube is like a helper that moves things around for us!
