Live in one of those parts of Australia where the temperature regularly drops below zero? (Hi Canberra!) Make the most of it by turning soft drink into a slurpee without the use of a freezer.
All you need to do, as the video above demonstrates, is leave a bottle of soft drink out in the cold for a few hours — to the point where it's really cold but not yet frozen. Slowly twist the cap off, and the soda will slushify itself. (Yes, that's a new word.)
