Coffee mugs that change their design when the temperature of its contents rise and fall are nothing new — but the idea to incorporate an animated battery is a move not to be overlooked.

It’s called the Battery Thermokruzkhus Mug, and it’s probably the nerdiest thing you can drink your coffee out of short of a Darth Vader helmet. The intense imagery of caffeine being highlighted as our primary morning power source is what makes this mug so exquisite.

According to the product description, the ceramic mug is a classic black color with a white outline of a battery on it. It holds 10 ounces of your favorite hot beverage, but when anything over 96.8F (36C) enters its quarters, you get to watch the green cells within the batteries wall light up. The green cells begin to fade as the liquid cools or is consumed.
