after a summer shower there is often a rainbow in the sky. it is made by sunlight shining through tiny drops of water in the air. the tiny drops of water split the sunlight into colors. these colors are red, orange, yellow, green, blue, indigo, and violet. the rainbow is always in the part of the sky opposite from the sun. usually it disappears the air. little rainbows can often be seen in the spray of a waterfall. when my mother sprays the grass and flowers on a sunny day, i sometimes see a little rainbow in her garden.
