Bubbles II

bubble grid

A raft of bubbles observed one day while doing the dishes. For some reason, many bubbles of equal size appeared. Here they have arranged themselves in a crystal. A few impurities (bubbles with a different size) cause crystal defects.

Bubbles have actually been used to study and visualize the physics of crystals. Here some videos, and an early article about the technique by Bragg.
