This picture shows how the bubble crystalized in the sun while attached to the stick. | Freezing bubbles |

Rumor had it that with the extreme cold that made it’s way through Southwest Minnesota the past few days, that it only takes a matter of seconds to freeze a bubble outside. So, we went and tried it. The result came about that in roughly -6 degrees Farenheit, a regular sized bubble took about five seconds to freeze into a “plastic” ball.
The bubbles don’t stay in a solid form forever, though. When the bubble breaks off and bursts, little pieces of soap film, flake off the bubble and float in the air like small plastic pieces. In order for all this to happen, the cold weather has to freeze the water molecule layer that lies between the two soap molecule layers. The crystals form in the water layer while the soap layer is slower freezing, and flakes off in the film. |
