Eco Dance

I set all of my cans of pop outside tonight so that they would get colder than they would have in my refrigerator. It worked, but a little too well because when I went to grab one it was frozen solid! I like putting them outside because they get colder and it saves energy to an extent. I do not mind when they are frozen a little because it is like a Diet Pepsi slush or something. Does anyone else do this to keep stuff cool in the winter?
