This year I am trying to count the number of rainbows that I see. Sometimes the shower stops and the rainbow disappears only for it to start again in roughly the same place a couple of minutes later. Is that a new rainbow or a rainbow that has been paused? There was one part-rainbow that endured for over 10 minutes. There were a series of rainbows that followed the one above and due to the lengthy gaps between the showers, the position of the sun had shifted which meant you could tell the rainbow was not aligned the same way over the loch. Rainbows in waterfall spray can presumably last all the daylight hours and must subtly shift orientation as the sun moves. Philosophically, is a rainbow even a thing at all? Anyway, the questions on ephemeral phenomena are keeping me entertained.
