This Marvel Avengers cold changing glass is sure to get your morning off to a strong start. Room temperature, the front of the glass shows the Avengers logo in black on both the front and back. When cold liquid is poured in, the glass transforms to reveal four classic Avengers superheroes in different colours - Captain America, Iron Man, Thor and The Hulk. Once the drink is finished the glass returns to its original state as it warms back up to room temperature. An essential for any Marvel or Avengers display.
