Divers in the area – stay alert! The red backdrop with white diagonal stripe is the flag flown from US boats when there is a diving party below the water. It provides the background for our diver, who cleverly asks, "I ‘breathe underwater, whats your superpower?" Hot liquid added to this heat-sensitive, black 11 oz. mug makes the diver appear and disappear like a person exploring murky waters near a coral reef.

Morphing Mugs® Heat-Sensitive Mugs
At room temperature, Morphing Mugs Heat-Sensitive Mugs appear to be black at room temperature. When you pour your favorite hot liquid into the drinkware, watch as the hidden image magically appears!
