THIS WORKS WITH CANS AND BOTTLES; BEER, SOFT DRINKS, ETC.
- Fill a container (an insulated cooler is best) with ice, water and lots of salt (rock salt works best if available)
- You can't really overdo it on the salt here, but you can on the ice.
- The cold water chills the drinks fast, not the ice. The ice is just used to get the water cold.
- Make sure you have enough water to surround the drinks; it's the surface area of the cold water on the drink containers that will cool them quickest.
- Submerge your drinks as much as possible. Make sure they are not packed too tightly! You want the icy water to flow around each container. If you container has a top, close it.
- It should take about 5 minutes for drinks to cool, but the longer you wait (to a point) the colder the drinks will get
- Enjoy your icy cold beverages!
Why This Trick Works So Well
Plain water freezes at 32F. Salt water can get much colder than that temp and still remain a liquid
If you put your drinks in an ice-water bath, it will cool effectively because liquid conducts heat well, better than solid ice. The icy water pulls heat from the drinks and so the drinks get colder. But no matter how much ice you add to a standard water bath, it will never get down to 32F because that's the lowest temp the ice can get to.
What happens when you add salt to the ice-water bath, the salt lowers the freezing point of water. The ice starts melting, not because the water is getting hotter, but because the freezing point is getting lower. As the ice melts, it brings down the temp of the water to 32F and below if the ice is frozen in a 0F freezer; the water can also get down to 0F and so chills your drinks FAST!
BE SURE TO WIPE THE SALTY WATER OFF THE OUTSIDE OF THE BEVERAGE BEFORE YOU PUT THE CAN OR BOTTLE TO YOUR MOUTH!
