How does a hologram work? (in 1 minute)?

A hologram is like a picture that can look 3D even when it’s flat, like a sticker on a wall, but instead of just showing one view, it shows many views at once.

Imagine you have a laser, which is like a super bright flashlight. When the laser hits an object, like a toy car, it bounces off in different directions. Now imagine there’s another laser that doesn’t hit the toy, instead, it goes straight to a special surface next to the toy. This second laser is like a ghost laser, not seeing the toy but still taking notes.

When these two lasers meet on the surface, they create a kind of “picture” made out of light waves, this is your hologram. It’s like when you draw with crayons and then use a magnifying glass to see tiny details that weren’t there before.

Now, if you shine a regular light on the hologram, it acts like a window into another world, you can see the toy car from different angles, as if it was really sitting there. It’s not magic; it's just light playing tricks to make things look 3D, just like how shadows and reflections work when you're playing with toys in the sunlight.
