When Filled, This Heat-Sensitive Mug Reveals An Awesome Image Of The Northern Lights

Nothing is more exciting than pouring a warm cup of coffee into your morning mug — that is, unless your mug lights up to reveal a picturesque scene of the Northern Lights. Sounds like a dream? Nope, this product really exists.

ThinkGreek recently released a heat-sensitive mug that when empty, appears as black as the night sky. As soon as you pour in some hot liquid, an image of Aurora Borealis, also known as the Northern Lights, appears instantly.

The mug is made from ceramic and can hold up to 12 ounces of coffee. In fact, ThinkGreek even draws a comparison between caffeine passing through our bloodstream and particles passing through the magnetosphere:

Much as caffeine particles pass into our bloodstream and make us bounce off walls, so, too, the particles from solar winds pass through the Earth’s magnetosphere near the poles and share energy, causing a spectacular display in the upper atmosphere. When these particles collide with oxygen in particular at lower altitudes (up to 150 miles), the photon released appears green or yellow, giving a similar light show as to the one captured on this mug when you fill it with warm liquid.

The mug is available on the ThinkGreek website for $14.99.
