Also, I keep one or two in the car as an impromptu ice-scraper (works well on light frost).
It took me a while to figure out what you meant by improptu ice scraping...
(I'm a Floridian. It only frosts up about once a year, if that)
But I do like those ideas too. And I'm checking out those ideas now.
And I am really liking the bowl idea.
How did you do that?
