Have you heard of Coffee Joulies? You drop one of these in your coffee and it cools it down to a drinkable temperature. But wait, it gets better….the Coffee Joulies actually keep your coffee warm for a longer period of time. Here is what they have to say about their coffee technology:
Each polished stainless steel shell is filled with a special phase change material that melts at 140°F. Put them inside your coffee and they absorb heat when it is too hot and release it back into your coffee to keep it at the perfect temperature.
Pretty cool (or should I say HOT), right?
