Fun Fact

Have you ever wondered why the sky is blue?  Well, let me tell you.  The air that we breathe is only 20% oxygen, which is colorless.  It's almost 80% Nitrogen, which is actually NOT colorless.  When you compress Nitrogen to a liquid or a solid, it is sky blue.  So there you have it.  The sky is blue because sky blue is the actual color of Nitrogen, which makes up the vast majority of the atmosphere.  (or rather nitrogen splits the blue component of the sun's light out, if you really want to get technical, but they basically mean the same thing)
