Beer drinking is one of the world’s favorite pastimes. So as the weather started heating up, we felt a scientific duty to investigate this burning beer-related question: what is the most effective beer can cozy?
We took temperature measurements using a digital thermometer with a metal probe. In most of the experiments, the probe was submerged 5.5 cm into the beer, at the approximate midpoint of the can. All experiments were performed outdoors, with ambient temperatures varying from 90F (32.2C) to 103F (39.4C). Except as noted, all beverages used were 12 oz. (355ml) domestic beers. The starting temperatures for the beers ranged between 35.7F (2.1C) and 43.7F (6.5C)
