How does Frost on Windows actually 'work'?
I have been enjoying a wondrous display of frost 'paintings' on my windows lately here in Vermont. But this morning I awoke to a very unusual one and want to ask how this may have occurred.
There is a heart on my entryway window, about a foot high. How can frost create the outline of a heart without divine intervention (not that Nature is not divine in itsself...) but this is unusual.
Can frost be affected by what was already on the window (which I cleaned when I moved in here 2 months ago...) I am thinking somebody drew a heart with a finger and no one could see it til the frost came along.
Would love to be educated on this.
