I'm freezing here in this NEGATIVE NINE DEGREE weather.
But, I must say, this is awesome. When I am boiling water for my third cup of French Press coffee, I may have to make a bit extra to turn into a cloud. If you are also afraid of losing your toes to frost bite (inside the house), you may want to have a look.
ETA: This is utterly amazing. If you're getting cabin fever and have a bit of ingenuity, give it a try!
