Ice is a magnificent thing. It cools refreshments down and keeps them cool, even when the heat of summer is threatening to make your chilly drink of choice disgusting. The only problem is that it adds tap water to your beverage, and any other chemicals that might be in it.

If you want to cool your drink without having some H2O splashed in there, Pucs might be of some use to you. These little stainless steel pucks will let you bring your drink to just about any temperature you desire. Obviously you’ll need to put them in the freezer first to be effective. When you combine more of these little rounded metal marshmallows in a single glass, it can cool things off several more degrees, and when you’re done you can toss them in the dishwasher! These Pucs come in a set of 6 for $38, which includes a hardwood maple or walnut case.
