Self-Cooling Soda Bottles Coming Soon
Good news, watered-down soda haters: Ice is dead. According to Mirror.co.uk, Coca-Cola has developed a new bottle that self-cools the liquid contents inside as soon as it is opened. Reportedly, the bottle will first be used for a new Sprite drink called "Super Chilled," which launches next spring.
Unlike those self-heating meals, which use a chemical concoction that often winds up fouling the taste of the food it's supposed to be warming, the bottles are speculated to rely on the simple physics of decompression. When something is compressed it typically gives off heat. When it's rapidly decompressed it absorbs heat, getting cool quickly. This is the same reason the contents of a CO2 fire extinguisher come out ice cold when sprayed.
Incidentally, there's no faster way to cool down a warm can of soda or beer than by spraying it with a CO2 fire extinguisher (if you don't mind the cleanup).
