Not all drinking glasses are created equal, as you can see with the $20 Clink! Glass. Yes sir, instead of gaining some courage through the favorite liquor of your choice kicking in after a few swigs, why not take a back seat and let your drinks do the entertaining for a change? This is an ingenious rocks glass that will turn the process of aerating your spirits into a fun, and surprisingly tricky, game. All you need to do is fill up your glass, give it a gentle swirl, and redirect the pair of rolling balls beneath your drink into the two ridges. You can definitely think up of some new drinking games with the Clink! Glass when using it with your mates for sure.
