Of course, everyone loves to have ice cold drinks, however what can you possibly do if you run out of them and all that is left in the back of the pantry is a warm can? You might have heard a couple of methods, however, there is one method which can make that drink colder than ever in merely under 2 minutes. In order to cool off any beverage really fast, the trick is not only fast mixing, but also exposure to super cold temperatures. Ice water with salt added is one of the best ways to do this. The addition of salt to the mixture assists in decreasing the melting rate and increasing the freezing rate, thereby allowing the water to stay colder for longer when the drink is added. The video below will give you all the details:
This trick can be very useful when your fridge is too full or everyone at your party has already drank all the ice cold cans. During the making and mixing of ice cream, addition of salt to ice water is usual, however it comes in super handy in transfer of the cold thermal energy in the water to another object. An enormous amount of thermal energy is transferred to the warmer object as the freezing rate is increased and the melting rate is decreased.
This technique of cooling drinks is extremely effective. The temperature change was 19˚C (34˚ F) which is some serious chilling only after 2 minutes of mixing. In case you are more of a bottle person, this cooling method will work on nearly any bottle, as long as you have a bowl big enough to hold the mixture. If you run out of ice as well, then you can wrap your drink in a cold paper towel and place it in the freezer. Leaving it there for about 10 minutes normally gets it nice and cold.
