Day and Night mug

This is a beautiful mug that shows you Earth landscape during night or during the day, depending on the temperature of the beverage (preferably coffee) in the mug. Simply fill it with caffeinated beverage of choice and it will light up, showing your beautiful daytime landscape of our planet. Once the beverage cools, the mug slowly turns back to the nighttime landscape (its default state). The best thing is that this means you automatically know when the beverage is cool or hot so you don’t accidentally sip on the terribly tasting cold coffee.
