Reusable Instantaneous Beverage Cooling Device

A cooling device for cooling beverage containers and their contents, such as, but not limited to, twelve-ounce aluminum cans. The device comprises a cylindrical body open at its top and having a bottom, where said cylindrical body includes an inner wall as well as an outer wall so as to form a plurality of compartments. In use, a beverage container is inserted into the innermost compartment surrounded by the inner wall while a solvent is added to the annular compartment between the inner and outer walls which contains a salt coolant. The dissolution of said salt in said solvent induces an endothermic chemical reaction capable of instantly cooling the beverage container as well as its contents via contact with said inner wall. Separation of the solvent from said salt coolant allows for subsequent reuse of the cooling device.
