Foghorn

Okay, kiddo, have you ever seen a big, loud horn that they use on boats? That's called a foghorn. When a boat is out in the water and it's really foggy outside, it can be hard for other boats to see it. That's where the foghorn comes in. The boat captain will press a button and the foghorn makes a really loud, deep noise that other boats can hear. It's like a giant whistle that lets everyone know where the boat is, even if they can't see it. This helps keep everyone safe and make sure boats don't crash into each other.
