Climate Change Mug
When you pour in hot liquid, the mug shows what will happen when the polar ice caps melt before your very eyes, coastlines shrink and ocean levels rise, Florida dissolves and Central America all but vanishes. Show you care with a Climate Change Mug! It won't fix the problem... but it will illustrate it in a really cool way.
3" diameter, 10 oz. Disappearing mugs are not dishwasher safe but are microwave safe.
