Gewgaw cools down coffee to 140 F, then keeps it there for hours

So far 3,383 people have pledged $205,650 on Kickstarter towards the Coffee Joulies project. I didn't know that coffee cooling down too quickly was such a big problem.

Coffee Joulies work with your coffee to achieve two goals. First, they absorb extra thermal energy in your coffee when it's served too hot, cooling it down to a drinkable temperature three times faster than normal. Next, they release that stored energy back into your coffee keeping it in the right temperature range twice as long.

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.
