Y’all mad at it being AI, but I think you might have missed out on a very fun thermodynamics problem… How cold does it need to be outside to keep the beer at a chilled drinking temperature, but also how thick does the insulating layer need to be between them and the beer to keep them comfortable, without going hypothermic? I’ve been out of the physics game for a while so I cheated and asked AI. - “Chilled beer” target: 4 °C - Skin temperature (inner surface facing the beer): ≈33 °) - Beer thermal conductivity ≈ 0.6 W/(m·K) - Heat-loss budget (steady-state) for comfort at rest ≈ 80 W per m² - Required foam liner ≈ 9.4 mm (0.37 in)

Kind of bulky for an average outing but given a certain situation or event!

¯_(ツ)_/¯

AI is a really dumb content generator but can be an interesting fun fact approximater!
