If you’ve spent any time in upscale cocktail bars, you’ve probably noticed they all use giant ice cubes. The thought process behind that is the bigger the ice cube, the slower the ice melts, therefore allowing you to enjoy your drink undiluted for longer. And it looks cool and gives them an excuse to charge you $16 per drink.

For just $10 today, $3 less than usual, you get three trays; two ice balls, and one ice cube, and achieve that same effect at home.
