Why Do Holograms Look Like Real People?

Imagine you're looking at a picture that moves and changes like it's alive. That's a hologram! A hologram uses special light to create a 3D image that seems real. It works kind of like when you use two eyes, each eye sees something slightly different, so your brain puts the pictures together and makes them look alive.
