Have you ever noticed that the ice that forms in puddles doesn't always have a flat surface. If I manage to get to icy puddles before my children have jumped on the ice and broken it into small pieces I love to look at the patterns, and the trapped bubbles of air beneath the surface. This photo shows a piece of ice I managed to rescue from my children! Do you know how these patterns are formed? I'd be interested to learn!
