A rainbow is made of the colors red, orange, yellow, green, blue, and violet. Where did the rainbow come from? All the colors exist in sunlight. We can’t see them because they are mixed together.
Easy and Fun Rainbow Science Experiments
When sunlight moves from the air to the water in the glass, it bends in a special way. When it bends, the light separates into all the colors of the rainbow. It’s called refraction. From How To Make a Rainbow video
We tried this on our own but with much poorer results.
Our hypothesis: our plate was too large. Try again with a smaller plate so the colors have less area to run together.
This is another fun rainbow experiment to try.

We did a similar experiment on a much smaller scale; we just placed 4 skittles in the bottom of a flat bottom bowl and watched the 4 colors each take over their own quadrant. It was really neat.
Hi Mother of 3,
It’s remarkable how something so simple is so fun for kids to do! And I love how it teaches them about science and color theory. We ended up eating the leftover Skittles!
I need to try that Skittles experiment with my kids.
Hi MaryAnne,
I was surprised by how it really does work. It’s fun and easy too! Get a flat white plate though, if you can!
