Put a beer or soda in the freezer to cool down fast? Calculate the exact chilled window and prevent shattered bottles or burst cans.
Targeting refreshing cold (~4°C / 39°F)
Water expands by 9% when freezing. In carbonated beverages (beer, soda), freezing pushes dissolved CO2 into trapped pockets, creating extreme hydraulic pressure that can rupture aluminum seams or shatter glass violently.
If you need the drink chilled right now without any explosion hazard: submerge the can in a bowl of cold water with ice cubes and 2-3 tablespoons of table salt. Salt causes freezing point depression (-3°C) and water provides 25x higher thermal conductivity than freezer air. Chills cold in only 3 to 5 minutes!
