Oil Bubbles

Well I tried to get away from flowers today - which is pretty hard for me at this time of the year.
I thought I had better hone in on trying to get some good images of oil on water as I am going to do a workshop on Macro.
I have not got the right gear yet to do it. I am looking for a table with glass in it and went to a second hand place today to try and find one, but no luck, so trying my old method of a tall glass vase, with CD's at the base.

Thank you every one for visiting my Anemone flower of yesterday, the white on white. I had so many hearts and stars, and top spotlight that I was blown away.
