Imagine you're drawing with light. A hologram is like a picture made of tiny waves of light that come together to form an image in the air. Instead of using paper or screens, holograms use laser light to create pictures that look 3D and can even move! It's kind of like magic, but it's really science.
Examples
- You see your favorite singer on stage, but it's just a hologram!
- Your phone shows a hologram of a spaceship landing.
