Review on Revive Your Mornings with Color Changing Zombie Mug: Hot/Cold Heat Sensitive Ceramic Mug 11oz by Djuan Thompson

I bought this mug as a Christmas present and couldn't help but try it myself before wrapping. It works exactly as advertised. I filled it with hot water from our dispenser and after a few minutes the blackness was gone and zombies appeared that stay open until the mug cools to room temperature. very cool! Haven't tried washing it yet so not sure how it will hold up but I wouldn't wash this mug in the dishwasher. for fear it will ruin the heat-sensitive image.
