A rainbow is like a magical bridge made of colors in the sky. When the sun shines after it rains, the tiny water droplets in the air work like tiny prisms. They catch the sunlight and split it into many colors, just like when you shine light through a crystal and see colors on the wall. This makes a beautiful arc of colors that we call a rainbow. It’s like nature’s way of painting a picture in the sky just for us to see.
Imagine the sky is a big piece of paper and the rain is a box of crayons. When the sunlight comes, it uses the crayons to draw a big, colorful smile across the sky. The colors are always in the same order: red, orange, yellow, green, blue, indigo, and violet. It’s like a giant colorful slide that you can see but not touch.
Think of a rainbow as a treasure chest in the sky. The sun and rain work together like a team to open this chest and spill out all the beautiful colors. It’s a special surprise that shows up only when the sun and rain decide to play together.
