What are hinges?

A hinge is like a door’s secret friend, it lets the door swing open and shut.

Imagine you're playing with your toy box. You have a lid that you push down to close it, but sometimes it gets stuck. Now imagine if instead of pushing the lid down, you could swing it up and down, just like how you move your arms when you do jumping jacks. That’s what a hinge does, it lets things swing back and forth.

A hinge is usually made of two parts that are connected together. These parts let the door or lid rotate, kind of like how your elbow lets your arm move around.

When you open a door, the hinge lets it turn on its side, just like when you swing your leg over the edge of a chair to sit down. That’s why doors don’t just slide, they swing!

Some hinges are even like a playground swing: smooth and easy to move. Others might be bumpy, like climbing up a rope ladder, but either way, they help things turn and twist! A hinge is like a door’s secret friend, it lets the door swing open and shut.
