How to Instantly Freeze Soda




This works with any carbonated beverage . Take your beverage and cool it down to a temperature around 20F or -7C.Either the freezer or outside if it is cold enough. When opened it will freeze instantly.

The reason:
This demonstrates the principle of freezing point depression. Pure water at 1 atm will freeze at 0C or 32F. When something is dissolved in it the freezing point drops to a lower temperature. This is why when roads are salted there are puddles even though the temperature is below freezing. The more salt the lower the temperature must go before it freezes. When you open the bottle it does the opposite. The freezing point goes from (a guess) -10C to around 0C when the CO2 leaves the solution (the concentration decrease). Since the soda is at -7C it freezes instantly when the CO2 leaves the solution.

    but how do you let it go to a temperature of 20F. Or do we put in a small chunk of dry ice.

    please... quit trying to get more money by posting on this site... if you want to write a set of instructions on how to do it, GREAT.... but viral videos belong elsewhere on the web(like metacafe, where your video is hosted)

    the point of videos is that you don't need to post instructions on how to make/do it. and if you look there are rudimentary instructions on how to recreate what you see in the videos
