This Batman cold changing glass is sure to get your morning off to a strong start. At room temperature, the glass features a black and white design that includes wraparound artwork of Gotham City at the bottom, as well as the iconic bat signal projected into the sky on the front, with the words, "Welcome to Gotham City" printed on the back. When cold liquid is poured in, the glass transforms to fill the once black and white city buildings with light and Batman's signal shines yellow so all of Gotham's criminals know the caped crusader is never far away. Once the drink is finished the glass returns to its original state as it warms back up to room temperature. An essential for any DC Comics or Batman display.
