Have you ever scalded your tongue by accidentally drinking coffee that was too hot? The Heartea tumbler might be able to help you avoid such situations in the future. Designed for the Nanum project, which is a charity that donates 100% of its proceeds to provide educational scholarships to impoverished children, the Heartea sports a glowing heart in the center that glows in different colors to indicate the temperature level of the beverage contained within. Blue indicates a cold beverage, while orange means it’s warm, and red obviously indicates piping hot. It’ll set you back $25, which isn’t too steep a price to avoid scalding your tongue.
