Day/Night Mug

Simply pouring hot water into this great mug is enough to turn night into day. It's heat-reactive, so when you put your morning brew into it the dark image of the world map will gradually brighten into a pleasant, traditional blue map of the world. The map itself is a properly detailed representation of the world and makes a lovely decorative item for any office. So if you've got a nagging desire to see the Earth as viewed from space next time you boil the kettle, look no further than this charming mug.

Features:

• A heat-reactive mug that reveals a map of the world.
• See more detail as the mug cools.
• Dishwasher safe.
