I also live in an area with cool clear water in the creeks. When I take a drink, I stick my whole face in the water and take deep slurps. I love it.
I just realised something that my subconscious mind has been trying to tell me for days.
The water droplet looks uncannily like a champagne saucer glass turned upside down. I know the base is a bit free form but it's such a good likeness (in my mind anyway), with the first ring of ripples being the rim of the glass.
A stunning image of course.
A toast!
