Keep that coffee warm!
Coffee Joulies have turned the idea around and they developed little coffee bean like "Joulies" that will cool down your drink if it is too hot and keep it warm when it would become too cold... Kind of sound impossible, doesn't it? But hey, apparently it works fine. Another great idea for a holiday gift? Yes, but don't bother, all Joulies are sold out. You'll have to wait until January to get yours.
