So you want to know the impact of global warming? Just pour hot liquid in this mug and you’ll see what happens as the sea level rises! For a mere $11.95 you too can have this great novelty mug. See the images watch the sea level rise! What an interesting use of phase change material, recently I posted an entry on tile that changes color with temperature. If you want a mug, you can get one here.
