I guess this makes sense when you think about it, but I never thought about it. Soap bubbles don't stand a chance when it's freezing outside, as YouTube's NightHawkInLight elegantly shows us.
At least it doesn't look like a violent end for the bubbles. They don't really shatter, they just sort of vaporise into little wisps, and drift off into the icy breeze. It's almost more mesmerising to watch than it would be if they stayed whole. See, you can have fun outdoors, even when it's frost-on-your-eye-lashes cold. [NightHawkInLight]
