The most incredible technological innovation I have seen in some time comes courtesy of... 7-Eleven?
7-Eleven teamed up with a manufacturing company on SELF-CHILLING CANS. You just twist the base of the can and it uses carbon dioxide to cool it down, even if it's been sitting in the sun... no refrigeration needed.
They're testing the cans with cold brew coffee at some stores in the L.A. area. There's no word on when they could go nationwide... or expand to other drinks.
Budweiser, Coors, I am looking at you!
