With the past couple of days seeing Ottawa in a deep freeze, I thought I would perform that old trick with hot water.
Here's what I made (and pardon the shaky camera; I should have used a tripod).
And on the next morning, I stopped on Bate Island during my morning commute to capture the frosty mist as it came up from the river and floated through the trees. At the time, it was 37°C with the wind chill. In the five minutes that I took to shoot photos, my uncovered hands seized up.
Stay warm, my friends.
