A Photo a Day: My Daily Sustenance, Day 18

Maybe you'll think, "What is she doing, photographing bubbles in a sink?"  Well, I thought it was interesting.  I also wished I had a microscope camera to show a close-up of the bubbles.  Then I'd be able to note more clearly how the bubbles are connected.  Is that strange?  Oh, well, if it is, I'm okay with that!
