When I first saw this, I thought for sure it was a belated April Fool's joke. Over-sized metal coffee beans that can keep your coffee at perfect temperature for hours without reheating? Yeah, right. But believe it or not, these magic beans are real.
According to the product's Kickstarter page, these beans will cool down your scalding hot coffee to an acceptable 140° Fahrenheit and then hold it around that temperature for as long as five hours.
How is this possible? The creators of the product, Dave and Dave, have developed a substance they call "Phase Change Material" that is designed to melt and absorb excess energy until it reaches 140°F. At that point, the material begins to release the stored energy, thus maintaining the temperature of the coffee.
Dave and Dave reassure us that their joulies are perfectly safe. Not only is the heat-absorbing material itself "100% edible food-grade magic," but each bean is coated with food-grade stainless steel. They say the beans can be run through the dishwasher and can be re-used indefinitely.
The project is currently 6 days away from their Kickstarter deadline, but they've already surpassed their fundraising goal by leaps and bounds. Reading between the lines, it sounds like the joulies will cost about $50 for a package of five and the first round will be shipped out within 12 weeks after the Kickstarter fundraiser ends.
