How to chill a beer quick

In case you don't know. The fastest/simplest way to make a warm beer cold is:

1. Fill a bucket with ice, water, and salt. (For a regular bucket I would use 1-2 cups of salt.)
2. Add cans or bottles of beer.
3. Swish around for about 3 minutes.

Except for the salt this may seem like common sense. But the salt is very important. With water and ice alone you are looking at 20 minutes or more instead of 3.

I learned about this years ago but Mythbusters reminded me.
