I always like seeing what Ben Krasnow is up to in his garage, whether it’s making astronaut ice cream or a refrigerator that works by stretching rubber bands. (Ben was a guest on my Cool Tools podcast a few years back). In the latest episode of his excellent Applied Science YouTube channel, Ben describes the process of making pigment that absorbs even more light than Vantablack, which absorbs 99.965% of visible light.
