A rainbow is formed when white light (such as sunlight) passes through water droplets, ice crystals, or glass. The light rays are refracted, or bent, by different amounts depending upon their wavelength. This has the effect of spreading the white light out into a broad band of the colors making up the white light.

Tossing It All Into the Wash


In February the Explorers spent a couple of sessions doing exactly what your laundry says not to do—mixing all the colors together.

Spin Cycle


In March the Explorers investigated the relationship between light and color—and found that you can not only split white light into all of the colors of the rainbow, you can also turn the rainbow back into white. Well, sort of, anyway.

Somewhere, Inside the Rainbow (Part 2)


Having made our space age color wheels (from such high-tech materials as posterboard, construction paper, scissors, and glue) during our previous session, it was now time to put the finishing touches on them and get them to spin.

Somewhere, Inside the Rainbow (Part 1)


The Explorers spent a couple of sessions investigating the nature of light, first taking it apart to make rainbows—and then putting it back together again. Sort of.

Secret Rainbows

In February 2009 the Explorers spent a session investigating the nature of light. They learned that white light is actually anything but white, and that nearly every beam of light has a secret rainbow hiding inside it.
