Global Warming Mug

This topical mug really stirs up the debate on global warming.

As you add a hot drink to the mug, the sea level gradually begins to rise, illustrating the effects that global warming will have on our planet's coastlines.

Thanks to the thermochromatic printing technology (that means the ink changes colour depending on its heat!) when the mug cools off, the coastlines of the earth return to pre-global warming levels in just a few minutes (if only it were that easy).

Heat Sensitive Global Warming Mug features:

• Approx 9.5cm diameter
• Please note mug is not suitable for dishwashers
