Batman DC Comics Heat Reactive Glass - Bat Signal

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 at the front, along with the words "Welcome to Gotham City” printed on the back. When cold liquid is poured, the glass transforms to fill the once black and white city buildings with light and Batman's signal glows yellow so all of Gotham's criminals know the Dark Knight is never far away. Once the drink is finished, the glass returns to its original state by warming up to room temperature.
