Using Science to Defrost/Defog a Windshield

We live in the Midwest, so it's just a part of life for us, especially those of us who park outside. Frost covered and/or fogged up car windows and windshields becomes part of our daily routine.

Over the years, I've used a variety of items to clear off the windshield of my car. I've gone with scrapers, both the old-school type, and the ones that you plug into your car's lighter that warm up and supposedly remove ice and snow quicker. I've used cassette tape boxes, and CD cases. I've poured hot water (that had been made into coffee) over the windows, too. I even went with a spatula one time when there was nothing else I could find.

If only I were more science-minded.

If you're not into following some scientific method, fill up a spray bottle instead:
