Art Lebedev at it again with new mug

The folks over at Art Lebedev have come up with a brand new idea – a mug that shows just how hot the contents of its drinks are through a rather interesting format. You will find the silhouette of a battery symbol on the outside, and there is a temperature strip which shows the current temperature (a rough guesstimate). This strip will become visible only when the mercury rises to 36 degrees Celcius (96.8 Fahrenheit) and above. How about it?
