A coffee mug that never lies!

You know those coffee mugs with cats or something about Mondays on them? This Hot and Cold Color Changing Mug ain't one of those. Sure, it might seem like your staple office mug in typical white or black. But add a hot beverage of your choice, and watch with drooling amazement as this color changing coffee mug takes action by announcing a heated liquid has entered its white container with the words "HOT" in black. But wait, what happens if I want something like iced coffee? No problem: the heat changing mug has got it covered. In white, "COLD" will appear on a transformed black mug. Grab yourself a Hot & Cold Color Changing Mug-- and, sure, why not a doughnut or four!
