Cheiroscope

A cheiroscope is a special tool that helps you look at tiny things up close. It's like a magnifying glass, but it has a light on it to make it easier to see the thing you're looking at.

Imagine you're trying to see something really small, like a bug's foot or the letters on a coin. If you just use your eyes, it's really hard to see. But if you use a cheiroscope, you can hold it really close to the thing you're looking at, and it will make it bigger and easier to see.

The cheiroscope works by using lenses (kind of like glasses) to make the small thing you're looking at look bigger. And the light on the cheiroscope makes it brighter so you can see more detail.

So, the cheiroscope is a special tool that helps you see tiny things up close by making them bigger and brighter.
