Soap bubbles are wonderfully ephemeral, their surfaces constantly in motion as air currents, surface tension variations, and temperature differences make them dance. In this video, though, photographer Paweł Załuska focuses on freezing soap bubbles. Watching the growth of ice crystals across the bubbles’ thin surface is mesmerizing. Snowflake-like crystals can nucleate anywhere on the film and, as in the sequence at 0:48, those crystals can float around on the bubble’s surface like snowflakes drifting on a breeze until enough of the film solidifies to bring the bubble to a halt and, then, a collapse.
