1 Serron: All right, this is the Street of Shadiest Bars.
2 Serron: Now we just need to find this Vantablack Market.
3 Serron: If it’s illicit, I wonder how easy it’ll be to recognise.
4 Iki Piki: I think we’ve found it. {there is a black void on the street where a building should be}

Coincidentally, since I wrote the last comics about the Vantablack Market, researchers at MIT have announced news of a new coating even blacker than Vantablack.

The material works on roughly the same principles, with aligned carbon nanotubes capturing incident light. However, whereas Vantablack absorbs 99.96% of incoming light, this new material absorbs about 99.995%, meaning it reflects only about a tenth as much light as Vantablack. That's a significant leap in blackness! Although I expect in practice that a human eye wouldn't be able to tell much difference.
