You swing by Starbucks before work, longing for a latte or flat white to bring you to life before a morning full of meetings. The barista hands over your cup of energy for the day and with a smile on your face you continue your journey to the office. You finally lift the cup to take a sip, and much to your dismay instead of enjoying the first taste of caffeine your tongue is brutally scalded by the piping hot liquid. You now have a temporary lisp and food is tasteless for the next three days.

Not anymore — Coffee Joulies have come to the rescue of burnt tongues everywhere. The coffee-bean sized capsules are made of a thermodynamic, non-toxic material surrounded by stainless steel and are designed to cool hot beverages three times faster than normal and maintain a "perfect" drinking temperature for twice as long.

How does it work? The Joulies are made to melt at about 60 degrees Fahrenheit (coffee is typically brewed at 90, give or take), and as they melt they absorb that extra heat from the drink. When the drink starts to cool down, the Joulies release that heat and begin to re-solidify. They may be called Coffee Joulies but they work for any hot drink, tea, hot chocolate, you name it.
