Yesterday morning quite by happy accident a very vivid rainbow was discovered downstairs in our den. I took the mini-blinds that were on the windows down and the sun came in to shine through our large aquarium. The glass and water made a perfect prism and created one of the very brightest rainbows we have ever seen. The kids played downstairs in the light for nearly an hour. Claire was especially thrilled with her multicolored reflection in the aquarium glass. Yay for sunshine!
