Few things beat a cold beverage on a hot day. When time is of the essence, there are ways to cool down bottled or canned beverages quickly. Individual bottles can be wrapped in a wet paper towel and stashed in the freezer for a few minutes. However, if you will be having a party and want to get beverages ready for the crowd, create a salty ice bath. Salt does not actually make water colder, but it will suppress the freezing point of water. That means water can become much colder -- and retain that temperature -- without freezing over to ice. If no salt were added, the coldest the water would reach would be 32 F. By adding salt, water can get as low as -6 F. This means items submerged in a salty ice bath will get colder much more quickly. Fill a cooler half-way with ice. Add the beverages until they are covered by ice. Then add water until the ice is submerged. Mix in table salt or rock salt to suppress the freezing point of the water. After 10 minutes or more, the beverages should be icy cold.
