Preserve Your Bubbles

Short answer: When a soap bubble is blown in air well below freezing, the thin water film begins to freeze. Ice crystals form and spread across the surface in branching patterns, swirled by currents in the film, until the bubble becomes a fragile frozen shell.

Very low temperatures help the whole bubble freeze before it pops. The footage shows bubbles freezing outdoors on a snowy day.

Video transcript: Preserve Your Bubbles: In Deep Cold, a Soap Bubble Can Freeze Into a Crystal Shell

Did you know, when soap bubbles freeze, the process begins as the outer layer of water in the bubble starts to crystallize due to the cold temperature. As the air inside the bubble is warmer than the surrounding environment, the freezing typically starts at the bubble's thinnest points. Ice crystals form in intricate patterns and spread across the surface, creating a delicate frozen shell. The soap film helps to slow the freezing process, allowing you to observe the crystallization as it moves through the bubble. If the temperature is low enough, the entire bubble can freeze solid before popping. NOW YOU KNOW!
