A Japanese consulting firm has just developed a genius product called "Hotto! Raisu" where you can make a bowl of hot, steaming rice simply by adding cold water to their clever packaging! An exothermic agent in the foodstuff essentially steams the contents when liquid is added; a trick that could be incredibly useful to help feed those in areas hit by natural disasters. Currently, the rice is packaged with pickled ume plums, but if the marketing takes off, the team plans on developing more items for the menu. Link via the ever-terrific Boingboing.
