A signal mirror is like a super-powered flashlight that can send messages across long distances using sunlight.
Imagine you're lost in the woods and you have a mirror, like the one your mom uses to check her hair. With Coghlan's Signal Mirror, you can reflect sunlight toward someone far away, like a friend or a rescue team, so they know you're there!
How It Works
You hold the mirror up to the sun, and then you twist it just right until the bright light shines in a straight line. That’s called a signal. If you move the mirror around, you can make the light flash on and off, like a fun game of "flashlight tag" with your friend across the forest!
Why It's Cool
The mirror has little lines on it that help you aim the sunlight better than a regular mirror. It’s like having special helper lines drawn on your paper to help you write straighter.
You can use it during the day, and if you have a flashlight, you can also send signals at night, just like how you use your flashlight when you're playing hide-and-seek in the dark!
Examples
- A hiker uses a mirror to reflect sunlight toward a plane that's flying overhead.
