Made with heat sensitive ceramic, the Thermal Battery Mug by Art. Lebedev Studio is designed to look completely black until you pour in liquid over 96.8°F. Then, by the magic of a science we don’t fully understand, a battery icon appears, charging up and down with green power bars to match the level of your liquid. Science, you have truly outdone yourself.
