Pool Chemicals

I had to add chemicals to our swimming pool today, at least according to our pool supply store. I was intrigued by how the light acted upon the white powder as I poured it into the pool. I tried a bunch of different angles and approaches, but liked this "in pool" shot the best. It was little difficult to pur and shoot at the same time. I think it looks a little like something you would see in outerspace, if space were blue instead of black.
