How Much Ice You Need to Properly Chill a 12-Pack

Business Insider's Rhett Allain (a "geek physics" expert) recently calculated the amount of ice you should have in order to properly chill a 12-pack of cans or bottles.  

According to his calculations, if you start with 12 drinks at room temperature and want to chill them to 0 degrees Celsius, you'll need 250 grams of ice per drink.  That works out to 1.5 kg for a six-pack and 3 kg for a 12-pack.  

Allain recommends using one 10-pound bag of ice per 12 drinks.  This will cool the drinks and leave behind ice to keep them cold for a longer period of time.
