Whistles

What Is a Whistle?

A whistle is a tiny tool.
You blow into it.
It makes a high, squeaky sound.

How Does a Whistle Work?

Inside the whistle is a small hole.
When you blow, air rushes through the hole.
The rushing air creates the squeak.

Fun with Whistles

You can use a whistle while playing games.
It can be a signal to say “stop” or “go.”
You can make music with many whistles together.
Remember to blow gently and not for a long time.
