Battery Color Changing Mug

Nothing is more sad than an empty battery. All cold and lifeless, it needs rejuvenation. Luckily, the battery level on this mug is just there to indicate how hot your drink is!  As the morph mug battery cools down, it's energy level decreases; making the battery drain. This charming display of vitality lets you know if your beverage is still hot hot hot. The battery is black until you pour a hot beverage in the cup and that's when the battery turns green.
