Climate changing 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. Holds 10 oz. Disappearing mugs are not dishwasher safe but are microwave safe.
