INSTY COOL CAN/TUBES
It takes about 5 to 15 minutes to consume a canned beverage and the desirable drinking temperature while consuming is around 45° F. To get this temperature, the general public and retail stores may keep the beverages refrigerated for days until it is consumed or sold. This wastes valuable refrigeration space as well as electricity. No need to refrigerate your beverage or beer cans any more! The vaporizing liquid carbon Dioxide contained in a tube instantly cools the can.
