Raise a glass to raising sea levels

Here is a very interesting use of temperature sensitive inks from the Dentsu agency of China in association with the NRDC (Natural Resources Defence Council). The external face of the mug is a scene of an iceberg seen at a distance, which slowly disappears as the sea level rises, ironically activated by the addition of warm water to the mug itself. An immediate and effective way to illustrate the effects of planetary reheating of the environment, and in particular the effect of melting glacial waters.
