ELI5: Explain Like I'm 5

Dipleidoscope

A dipleidoscope is like a toy that looks through two mirrors to make a picture look bigger and cooler. It's like two mirrors facing each other, and when you put something in the middle, it looks like it's far away and you can see it better. Imagine holding two mirrors close to your face and looking at your reflection, but when you move your face, your reflection moves too, creating a cool effect. The dipleidoscope is used for looking at pictures, reading books, or just having fun with. It's like having your own magic telescope!
