Ottawa, and much of Canada, is in for very cold temperatures and arctic winds this week. Often when it is coldest it is also prettiest. When I went outside to take these photos I could here the ice on the trees cracking and creaking in the wind.
It is bitterly cold here again so I tried a trick I had seen and heard about, freezing bubbles. I made bubble mix then braved the -20°C temperature for a few minutes at a time to blow bubbles in our snow and ice covered back yard.
Most bubbles shatter while they are in the air or as soon as they hit a surface. Some float in the air long enough to freeze before they land on the snow.
