Tea patterns

I love watching patterns form in a hot cup of coffee or tea. You see deep swirls when liquids mix, and funny arrangements coming alive on the surface.

Yesterday morning, my tea was doing something really weird. There were tiny micro-bubbles on the surface, forming and popping rapidly in the shape of tree branches. What’s going on here? Are there branchy fractals on the surface of my Throat Coat?
