When this Aurora Borealis Heat Change Mug is filled with a hot liquid, it shows a magnificent image of the Aurora Borealis, or more commonly known as “The Northern Lights” on the side of the coffee cup.
It looks awesome and probably will take your mind off from what you are doing wherever you are. This 12 oz. Thinkgeek exclusive ceramic mug is neither microwave nor dishwasher safe. But it shouldn’t stop the nature lover from filling it with caffeine and getting ready for the show!
Enjoy the Aurora Borealis every time you fill up your coffee with this ceramic mug that reveals the glorious green lights whenever it heats up. A great gift for colleagues too.
