The paths of air bubbles in a frozen water droplet photographed in Walpole, Massachusetts, on 25 December 2017. The water droplet is hanging from the bottom of a Winterberry (Ilex verticillata) berry.
This is an extreme close-up. The water droplet was only ~4 mm long.
Once again, I'm not sure how these patterns were created. But it's fascinating to follow the paths of the air bubbles and to wonder about these micro-landscapes in our backyards.
