What are reflection holograms?

A reflection hologram is like a picture that changes when you move around it, just like how your shadow looks different depending on where you stand.

Imagine you have a sticker on your backpack, and when you walk around the school, sometimes you can see it clearly, and sometimes it seems to disappear. That’s kind of what a reflection hologram does! It's made so that light bounces off it and creates images from different angles, just like how you might look at your reflection in a mirror from all sides.

Think of it like this: when you shine a light on a reflection hologram, it acts like a special kind of mirror. Instead of just showing one image, it shows many, depending on where the light hits and where you're standing. That’s why it looks different from different angles.

You've probably seen these kinds of pictures in stores or on books. They might look like they're moving or changing colors when you walk past them, that’s because the reflection hologram is working its magic (not really magical, just clever!). You don’t need special glasses to see it either, which makes it even more fun!
