Battery Thermokruzhkus Mug
Caffeine is our power source, whether it's from coffee or tea or BAWLS. What better way for us to visualize our batteries being charged than a mug with a battery that powers up when we fill it with our piping hot caffeinated libation of choice? This ceramic mug is classic black with a white outline of a battery on it. Pour in your hot liquid - anything over 96.8F (36C) - and watch the green cells within the battery light up. As your beverage cools (or is ingested) the battery will fade into emptiness, reminding you that you need a refill. Product Specifications Ceramic mug changes color when filled with hot coffee or tea Holds 10 ounces of your favorite hot beverage Watch the battery "light up" when your mug is hot Love your mug: hand-wash only. The extreme temperature of a dishwasher will destroy the color-changing parts of the mug.
