Thank you for commenting. It is all of the things and none of them that you mention. It's just whimsy.
These opportunities have come along accidentally. It is monsoon season here and we put a detergent-like product in the pool to help control the hornets that like to swim with us. A gentle rain caused these bubbles, but all is not as it seems. Whimsy; what a great word.
I will hope for more accidents!
