Joulies keep your coffee at drinkable temperature
Coffee Joulies are the magical beans that fight to keep the temperature of your coffee just right. Made out of non-toxic material and covered in stainless steel, the Joulies cool down the coffee when it is too hot, and then give out the absorbed heat as the coffee starts to go cold. Ultimately, this ensures the coffee remains at a drinkable temperature for a longer time duration. The idea first saw success at Kickstarter, and has since gone into manufacturing mode.
