Question from Tammy: I was visiting my mom the other evening and we decided to sit on her back porch for a while.

We both sat down in metal chairs. Her chair had a cushion on it, but mine didn’t.

Question from Katy:  I have a very simple question that I’ve been curious about for most of my life.

Why is milk white instead of some other color?

I know you can change the color of milk by adding stuff to it (chocolate syrup for example), but milk always comes out of the cow white. I know that for a fact because I grew up on a dairy farm.  [Read more…]
