The Tardis mug is a geektastic invention that takes you (and your coffee) through time and space (sort of). The heat-sensitive mug rocks a London scenery when at normal temperature, however, when under extreme heat, the Tardis mug transports to outer space.
The greatest part is that this all happens before your very eyes! Hopefully, the Tardis mug will contribute to a more exciting morning cup of coffee. We suggest using it on those groggy Monday mornings.
