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?

    Is it weird one of the first things to think of with all this super dark paint to be “I bet someone have or will use this to do blackface”, or that this paint is dark enough so that anyone can do it no matter their skin color? Guess that would be pretty fair and equal, or maybe not... In second thought playing around with putting that paint on oneself and lying in wait in that room to scare people would be considered bf too, but what a concept though, maybe could settle for hiding behind the blanket and suddenly popping out I guess.

    Considering walls absorb almost all the energy from the light bulb, if u put some isolation outside of the walls, would it be possible to heat the room using only bulb, and if yes to what extent? And is it even applicable for this kind of purposes?
