Wanna look really cool at your next party? When you ask your pals if they’d like a cocktail ask if they want it on the rocks. If they say yes, fix their drinks and bring ‘em back with some of these ice cubes that are actually made from stone.
Just chill these special ice cube rocks in your freezer for about an hour before use. 2 or 3 rocks should keep your drinks nice and chilled. Originating from Sweden, the cubes are cut from a natural stone called Nordic Rock, known for its ability to retain cold (and to occasionally carry a tune). When not in use, you can keep the rocks in the included leather pouch. This also serves as a handy weapon if you feel the need to beat someone over the head.
You can grab a set of 10 rocks from UK gift retailer Mocha for £15.99 (appx. $29 USD). Rock on!
