There’s finally a real, working, practical self-refridgerating can. The Instant Cool Can (I.C. Can‚Ñ¢) is a 100% safe and environmentally friendly self-refridgerating process that cools using brilliantly simple water evaporation. In fact, it’s proven to lower beverage temperature by a minimum of 30¬∞ F (16.7¬∞ C) in just three minutes.
