      The raindrops act like a prism, so when the light from teh sun shines through them, the raindrops break the light up into its colours, Basically the raindrop bends each colour (or wavelength of light) to a different amount, so you can see the colours.

      Despite popular belief, not by the Nyan cat. See Ned’s answer! 🙂

      I’m with Ned on this one. The best view of a rainbow is when you have the sun behind you, a dark cloud in front of you in the distance which is raining. It’s the best view because the colours are more visible against the dark cloud background.
