Environmental Inspiration in Your Own Backyard

Winter Windows January 24, 2011

Proof that nature really is everywhere! While we should all try to get outside, there are definitely exciting things you can see while sipping cocoa wrapped in a warm blanket! Here is what I woke up to this morning:




“For frost to form on the windowpanes as well as on trees and grass certain conditions are necessary. Frost is made up of tiny crystals of frozen water. It forms when air that has a lot of moisture in it is cooled below the freezing temperature of water. This temperature, which we call “the freezing point,” is 32 degrees Fahrenheit and zero degrees centigrade, at sea level. When air becomes cooler, it cannot hold as much water as before. The excess water condenses on such objects as the windowpane. Now, if the temperature falls below 0 degrees centigrade, this water becomes crystallized. In other words, it freezes into a coating of interlocked crystals of water. What causes the patterns to appear in the frost on the windowpanes? For one thing, the tiny crystals have a certain structure which gives them a pattern. In addition, there may be tiny scratches in the glass, dust particles, air currents all of which help create the designs that “Jack Frost” makes on your windows.” Source





For more information on why frost occurs, you can go here. This site also includes info on how to “grow your own frost,” although I’m not sure how safe it is!  I was going to tell you to find frost pictures by just google image searching for it, but when I did a bunch of pictures of women getting.. intimate.. with snowmen showed up as well. Who knew! This might be a better option.

Do any of you have frost on your windows? What kind of patterns does it form? According to the same source listed above, frost covered windows used to be more common when most windows used to be a single pane of glass. Now most windows are made of 2 panes, and are more insulated than before, and thus get less frost. If you do have frost, though, I would love to see a picture! You can always send photos, questions, or ideas in to

If you don’t have frost growing on your windows, try watching the water coming down your window panes the next time it rains! Are running droplets attracted together? Do they follow the same paths or make a new one? Do they splash, splatter, bounce, trickle?

There is always something new to notice, in every place and every season!
