You might not live near the aurora borealis, but you can now experience it every time you have a cup of coffee. ThinkGeek has created a special heat-changing mug that reveals the glorious sight of the Northern Lights, when it’s filled with hot liquid. Left unheated, it simply displays a stunningly desolate landscape at the base of its handle.
ThinkGeek points out that as caffeine roars through our bloodstream to “make us bounce off walls,” it shares a similarity with the aurora borealis: the particles from solarwinds barrel through the Earth’s magnetospheres and share energy to create a mesmerizing sight. When they collide with oxygen at lower altitudes, the photons released look green or yellow–the same scene that’s on the mug.
The Aurora Borealis Heat Change Mug is available exclusively through the ThinkGeek website.
