The bubbles of air that have been drawn by wave action concentrated by an opening and closing gap on the ice of Okanagan Lake, go no further than the crack. Under the water, their air was stronger than the water itself; in the crack, the surface tension of the water is stronger than the air, and so they remain, both air and water at once, in balance.

If you measure either, the moment breaks and neither one is there. They are not a substance, but a relationship. So, beautifully, are we all.
