“I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.” —Genesis 9:13

Rain showers bring rainbows shimmering across the sky, sometimes while the raindrops still fall. On a full moon night, you can even see a rainbow in the mist of a full-flowing waterfall. For most of us rainbows appear like a gift, but you can increase your chances of seeing one, if you know where to look.

Rainbows in the sky appear only in the early morning or late afternoon, because the sun’s rays have to be at a slant to reflect the tiny prism of each water drop. The reflected light of the rainbow appears only when the sun is behind you. So on a rainy or misty day, or near a waterfall or fountain, in the early morning or late afternoon, stand with the sun directly behind you so your shadow falls straight ahead. Hold your arms straight out at ninety degrees. Now turn your head sideways to look halfway between your arms and your shadow, at forty-five degrees, and you should see a rainbow.
