You've undoubtedly heard that adding salt to your cooler can get your beer slushy. We decided to do a little test. You have room temperature beer, and you're thirsty now. Can salt help? If so, how much?
Supplies
Beer Slush Generator (Our conveniently packaged salt)
10 lbs of ice
Room temp cans of beer
ThermaData Thermocouple Logger
The Test
We punched a hole in the top of the can, and inserted the thermocouple so it was close to the center of the can. Then the can was buried in the cooler with plain ice for 30 minutes while we logged the temperature data. Next we removed the first can, dumped a packet of salt in the cooler, mixed it with the ice, and buried a fresh can.
What's the verdict? Check this out.
The ice and salt mix got the beer 10 degrees colder after 30 minutes.
