London-based startup Delta H Innovations has come up with an innovative self-cooling beverage can technology that could soon make drink refrigerators obsolete. Named “Cool Can,” the invention can lower the temperature of its liquid contents to between 42º and 44º. The Cool Can looks like a normal aluminum beverage can, but the base of the can acts as a hidden water container. When the button on the bottom of the can is pressed, the water is released into the space between the can’s double aluminum walls. Embedded between the walls are proprietary salts that start to rapidly cool the beverage inside when it reacts to the water. While it can take up to 10 minutes for the drink to sufficiently cool, it stays cool for up to 45 minutes. To let users know that the drink has cooled down enough, the Cool Can features a clever snowflake mark that turns from white to blue when the temperature drops low enough. Although the Cool Can is still patent pending, Delta H Innovations claims that they are already in talks with big brands like Coca-Cola and Red Bull to potentially adapt their canning process to include this new technology.
