I love rainbows, they're so pretty. It's hard to believe that it is caused by water bending light sometimes.
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets 
Yep it sure it, I couldn't remember that many details though lol. I really do like how the gay people have taken it to be their symbol too. 
Uhmnn,never knew it was used as a symbol. However the water droplets resulting in a spectrum of light appearing in the sky
