Imagine you're in a dark room, and then suddenly light appears from all around you, not just from one place. Holograms look like they’re floating because they use light coming from multiple directions to make an image appear as if it’s actually in the air. It's like when you see your reflection on both sides of a window at once, but instead of a reflection, there’s a picture that seems to hover in front of you!
Examples
- Your friend’s birthday card appears to hover above the table without any string or stick.
- You see your pet dog looking out from inside a glass ball, but there’s nothing holding it up.
