The first comment on wired has a very good tip: For best cooling you want to use a mix of Ice and cold water, with a ton of salt. This lets the water temp drop below freezing, and makes better contact with the cans/bottles, transferring heat away from them faster. It makes a pretty big difference, especially when you've got a bunch of warm beer / wine and want to get it to a drinkable temperature as fast as possible.
