Frozen Bubbles

For the last two days we have had arctic temperatures here.  Lows have been in the -20's, with wind chills double that, and our highs during the day hadn't gone above the minus teens.  Today we finally made it above zero (although not by much!) so I decided to take my camera outside for a few minutes and blow some bubbles.  They quickly crystallized into some pretty designs before collapsing in on themselves.
