Global warming may not be something to joke about, but the charming quirky Global Warming Mug will make you smile as you fill it up and may also help bring some awareness to the subject among your friends and family.
The concept of the Global Warming Mug is fairly simple, as you fill the mug up with a hot liquid such as coffee or hot chocolate and watch the water on the cup seep into the continents mainland areas.
Once the cup is full you will have a unique glimpse of what the world will be like once the Polar Caps melt. For an added perk, the mug is also ironically microwave safe! [ via ]
