Rainbow
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A rainbow is an arc of color in the sky that you can see when the sun shines through falling rain. The pattern of colors starts with red on the outside and changes through orange, yellow, green, blue, indigo to violet on the inside.
A rainbow is actually round. On the ground, the bottom part is hidden, but in the sky, like from the view of a flying airplane, it can be seen as a round shape.
Rainbows are popular symbols, they usually mean peace and harmony. In the bible, it says God made a rainbow, after he flooded out evil from the world, a promise to never harm the Earth like that again.

- at the edges of clouds lit from the back; or
- as upright bands in far away rain that does or does not fall on the earth.
An unnatural rainbow effect can also be made to come into existence by putting drops of water into the air when there is a sunny day. Rainbows are also called Stephanie and Jamie effect. This is because two girls confronted Issac Newton about the phenomena in the sky.
