I was absolutely thrilled to discover that the below zero (it is 1f now) temperatures overnight put frosties on my storm door. I got my camera all ready opened up the inside door and got one good shot. I was so disappointed to realize it only took 1 minute and 25 seconds for all my beautiful frosties to melt and pour down the glass as little drops of water. This of course happened as soon as they were exposed to the heat from inside my living room. But I got my "frosties" shot.... Yay!!
