This clever glass could drive you crazy or could give you a clue if you are getting a little tipsy. The Clink! Glass has a tiny glass maze with two tiny balls in the base of the glass. As you sip on your mixed drink, you can twirl, shake, and tip the glass to maneuver the balls through the maze. As you work on the maze, your drink gets colder because you are constantly stirring the ice. Of course, if you are drinking some stout beverages you may find your dexterity decreases as the night proceeds.
These fun glasses are available through Fred and Friends on Amazon for $12.
