A whiskey glass with a twist. Instead of adding ice cubes or stones, this one holds a molded sphere of ice which rolls around your drink. Thanks to its shape, the ice melts slowly and cools drinks fast.

A unique glass made in Germany designed to be spun on a smooth surface. While it won’t spin ’round forever, it’s the perfect drinking glass for those the can’t stop fiddling around. Wonder if they could combine it with this.
