I Painted My Entire Room With Musou Black-The World's Blackest Paint

In this video I paint my entire room with Musou Black to see what it looks like when the walls around you absorb over 99% of the light in the room. What happens when you turn on a light in the room?

  • "We can't really have a conversation because the light source is now behind me and you can't see my face at all." I guess sound isn't a thing anymore when you take light away.
