I was watching the news this morning and they had video footage of someplace in Colorado, or somewhere, where they saw a rainbow up in the sky. The interesting part was that it never touched the ground and went in a complete circle. The weather man said that all rainbows are circles. The only problem is that the ground usually gets in the way.
I never thought of it before, but it makes sense. Good piece of trivia and a fun little fact. 🙂
