Why Do Holograms Look Like They're Floating in Mid-Air?

Imagine you're looking at a picture in the sun. When sunlight hits it, different parts of the image bounce light back to your eyes. A hologram works kind of like that, but with more light tricks! Instead of just one flat image, it uses special light patterns to make things look like they're floating in the air. It's like magic made with light!
