It's about damn time science did something worthwhile. Physicist Rhett Allain just figured out exactly how much ice you need to perfectly chill a 12-pack of beer. Or a 12-pack of soda or water, if you're That Guy.

He did all sorts of thermodynamics, which we won't get into here. After all his calculations, he found it takes 250 grams of ice per drink. Exactly 6.6 pounds to cool a dozen beers.

If you drink slowly, you're actually better off using a 10-pound bag, since some of the ice will melt. Who's drinkin' slowly? It's Friday, these beers aren't gonna drink themselves.
