What are transmission holograms?

A transmission hologram is like a special picture that lets you see 3D images when light goes through it.

Imagine you have a toy box with different toys inside, a car, a ball, and a teddy bear. Now, imagine you could look through the lid of the box and see all those toys moving around in 3D, just like they're real! That’s what a transmission hologram does. Instead of looking at a flat picture, you see something that looks like it's floating in front of you.

A transmission hologram uses light to create this effect. When you shine light through the hologram, just like shining a flashlight through a piece of clear plastic, the light bends and mixes in special ways to make the image appear 3D.

It’s like having a hidden movie inside the picture, and when you look at it right, you can see all the action, just like watching a real toy car zoom around instead of just seeing a flat drawing of it.
