Colors of the Rainbow

With both of my kids I taught them the all colors of the rainbow, red, yellow, green, blue, purple, etc etc etc
We all know the excitement when after a long rain we look outside and catch a glimpse of a beautiful rainbow.
Even thou there is nothing as good as a genuine rainbow high in the sky, I decided to have the kids make the next best thing. ;-)

All I did was have my kids put some water in a shallow dish and then prop up a small mirror in the water at an angle. Then place the dish near a window and position the mirror so that sunlight hits it. The light passes through the water and bounces off the mirror, making a faint rainbow appear on the wall. If you do not have white walls, take a large piece of white card and hold it in front of the wall. Adjust it until you can see the rainbow.
To quote my lil' ones, "Ooh how pretty!" :)
