Asif Khan reveals super-dark Vantablack pavilion for Winter Olympics 2018
Asif Khan has unveiled a pavilion at the Pyeongchang Winter Olympic Games in South Korea, described as the "darkest building on earth".
The BRITISH ARCHITECT spray-painted the 10-metre-high temporary structure with Vantablack VBx2, a substance that absorbs over 99 per cent of light.
