Rainbows

We were in the back yard yesterday afternoon and came upon a wonderfully vivid rainbow.



Of course, the grandkids were in the pool and as we watched the rainbow, that prompted a discussion of the phenomena that have to come together to view a rainbow, and also the biblical promise that the rainbow is supposed to signify. If you look just to the left of the main bow, you can see a second one. Who knew there was such science in a rainbow.
