Imagine you drop a toy car inside a tiny hole, and you can't see where it went. So, you use a borescope to see what's inside the hole. The borescope has a tiny camera that helps you see through the hole and find the toy car.
Borescopes are very useful for people who work with machines or engines. They can use the borescope to see what's going on inside machines, without taking them apart. This helps them figure out what is broken or needs fixing.
