Behold the World's Darkest Building

The world's darkest building went on display at the Winter Olympics in Pyeongchang, South Korea. How do you make the world's darkest building? Simply coat it with a new material called Vantablack VBx2. Vantablack is able to absorb almost 99 percent of the light hitting its surface. The world's darkest building is part of display to show how energy could be produced from hydrogen.
