Okay, let's imagine you have a group of friends who all have different toys, but you want to know what toys they have without looking at them. That's where Eidors comes in - it's like a special tool that uses special ways to look inside things (like your friends' toy boxes) without actually seeing them. It uses electricity to do this. Eidors can tell you what's inside objects without opening them up. It's like magic! But it's actually science. Scientists use Eidors to look inside things like people's bodies to see if everything is okay, or even inside the ground to see what's hidden underneath. It's pretty amazing!
