Quick Chill - Chemistry in Action

Ever go to the fridge and discover there isn't any cold soda in there? Or have you ever just bought room temperature soda cans at the grocery store and wish you had a cold one to drink?

You could just put it in the freezer for a few minutes to cool it more quickly. It's faster, but not the best by cooling through mostly convection.

A better, and more geeky way, is to leverage some chemistry and use freezing point depression. Check out this video for a demo.
