Question:
Why does sunlight fade the colors on the papers I hang in the window?


Replies:
Alexandria,

If you are really only five years old, you must be a pretty intelligent little person to have noticed that things fade when exposed to light.

Sunlight is a kind of powerful form of energy that can sometimes break up the colored molecules into smaller pieces that are less colorful -- or even colorless. There are very few kinds of colored things that can stand being exposed to sunlight for a long time. That's why colored pictures in your family album are sometimes stored under a clear plastic page. That helps protect the colors. Even so, in time they will fade.

Any pictures you make are valuable just because you made them. Don't worry if they fade. They are pretty because you took the time to make them and they mean something to you.

Regards,
ProfHoff
