Rainbows and prisms

Lets go back and talk about one of my favorite non-oceanographic topics: Rainbows!

When I had my rainbow phase about a year ago, my mom sent me the movie below, which shows what you see when you look directly into the prism that paints these kinds of rainbows all over my parents’ living room:

When you look directly into the prism, you don’t see a rainbow like the one projected on the wall, but you see one color at a time. Only as the prism moves you experience all the different colors of the rainbow. And that is interesting because in a rainbow you see all colors at once, yet here you don’t. This is going to go into the next version of my rainbow movie, but for now check out my mom’s:

My renewed interest in rainbows was sparked one Saturday where I saw one on my way to the swimming pool in the morning.

And then a double rainbow on an evening walk with a friend.

And then another friend, F., sent me the picture below which he had taken at Heathrow and which he kindly allowed me to use for educational purposes on my blog.Screen shot 2015-06-07 at 8.09.47 PM

Are you as exited as I am that we are finally getting back into rainbows? :-)
