So last week I made an educated guess about why the sky is blue. Today I am going to tell you why it is really blue. So the sun or what it shines which is light has several colors. The rainbow colors as we all know. So the color blue is the shortest of them all. That is why the sky is blue, because blue is the one that reaches all the way to the sky. I made a guess like this but not exactly on the point. It was fun researching this. Like seriously who doesn't want to know things like this. 
   Of course a lot of people already knew this from basic science lessons we get at school. I guess i should pay more attention. Our science teacher Mrs. Poole went over this light subject about two weeks ago if I'm not mistaken. Although we did not go completely over this subject. I hope this was helpful
