Caffeine is our source of energy, be it coffee or tea or BAWLS. What better way to visualize batteries than a cup with a battery that turns on when we fill it with our hot caffeine libation?
This ceramic mug is classic black with a white outline of a battery. Pour the hot liquid, any amount greater than 96.8 F (36 C), and watch the green cells light inside the battery. As your drink cools (or swallows), the battery will fade away, which reminds you that you need a recharge.
