Why do the lines on paper fade (and eventually disappear) if left in sunlight?

Asked by arnbev959 (10906points) June 4th, 2008

I had a piece of lined looseleaf paper taped to my bedroom window, and over the course of five months the lines disappeared. Why?

Ultraviolet light (which sunlight has plenty of) can ‘bleach’ the paper by slowly breaking down various inks and pigments.

The line faeries come and use them to build nests.

Given enough time the sun bleaches out a lot of things. Colored fabrics fade, too. Even my hair does to some extent. In the winter, when the sun is blocked by clouds, my hair is a dark, dark brown. In the summer, however, the sun bleaches parts of my brown hair to an auburn/copper color. People ask me every summer if I dyed my hair – every summer I say no and tell them it’s from the sun.
