This Marvel heat changing mug is sure to give a super start to your morning. Cold, the mug shows the Invincible Iron Man and his logo on one side and his Arc Reactor on the other. When hot liquid is poured in, the mug transforms to reveal the Arc Reactor lighting up. Once the drink is finished the mug returns to its original state as it cools.
