Rainbows
A rainbow forms when sunlight shines on drops of water in the air: each drop splits the white light into colours, like a tiny prism, and sends them back. You see one when the Sun is behind you and low in the sky, in the morning or late afternoon, and the drops are in front of you. Red is on the outer edge and violet on the inner.
