Iridescence is like a magic trick that makes things shimmer and change colors when the light hits them. It's like the soap bubble is wearing a rainbow coat that changes with every move.
Some other things that are iridescent are:
* Butterfly wings: They have tiny scales that reflect light in different ways, making them look like they have different colors.
* Peacock feathers: They have special structures that make them sparkle and change colors.
* Seashells: Some seashells have a layer of special material that makes them shine with many colors.
So next time you see something that sparkles and changes colors, remember it's the magic of iridescence!
