The big brains at Popular Science magazine put their powers to good use by explaining the fastest way to chill beer.
You just have to fill a cooler with ice, water and lots of salt. The more salt the better.
Then, submerge the cans or bottles as much as possible and close the top.
After five minutes, you’re in business because the salt lowers the freezing temperature of the water, allowing your beer to get that perfect, frosty chill as quickly as possible. (Popular Science)
