Air horn

An air horn is like a really loud noise maker that runs on air. You know how sometimes when you blow really hard or scream at the top of your lungs, it can be really loud? Well, an air horn can make an even louder noise than that!

Basically, an air horn works like this: there is a container or canister that holds compressed air. Think of it like a balloon that's been filled up with air, but now the air is being held inside a metal or plastic container. When you press a button or pull on a cord, that air is released very quickly and it makes a loud noise.

The noise of an air horn can be heard from really far away, which is helpful in some situations. For example, if you're at a sporting event and you want to show your team spirit, you can blow an air horn to make a lot of noise and get everyone excited.

But it's important to remember that air horns can also be very loud and annoying, especially if someone blows one right in your ear. So, it's always a good idea to use them responsibly and be mindful of the people around you.
