Global Warming Mug
Next time you wrap your hands around a comforting cup of cocoa and drift off into a reverie contemplating such charming thoughts as global warming and whether you live on a hill or not, you can see at a glance whether you need to consider buying a boat anytime soon.
Just unwrap your hands and take a look at that nice mug with a map of the world on it. Things have changed. When you add hot water to the mug you will see the world’s coastlines slowly disappear under a hundred metres of water to reveal our much denuded landmass.
