The family joulies: Keep your coffee at the perfect temperature for longer

Coffee knick-knacks are a dime a dozen. Or. In this case. $40 for five. I give you “The Joulie” an energy transfer device of such ingenuity that it will drop the temperature of your coffee quickly into drinkable range, and then hold it there. For a long time. You can give this little product a “kickstart” and secure your share of the first run. Amazing.

“This amazing feat of thermodynamics happens thanks to a special non-toxic material sealed within the polished stainless steel shell. This material is designed to melt at 140 degrees Fahrenheit, and absorbs a lot of energy as it melts. This is how Joulies cool your coffee down three times faster than normal. Once it reaches this temperature, the special material begins to solidify again, releasing the energy it stored when it melted. This is how Joulies keep your coffee warm twice as long.”
