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

1.9M views259

    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?

    66. nevan o'connell

      When you were screwing in the light bulb it looked like crappy green screen

    67. Peter Peterson

      It really looks like you are in a really dark forest in a cloudy night or something, or in a really large cave, really spooky that you can only see the face. My brain tells me that the walls must be really far away, because I can't see them, but I can see your face with the lightbulb on. But the room is so tiny! It's like something out of a video game, and they forgot the background, or they are just making the 3D model.

    68. LazyBunnyLyn

      Ffffff turning on the lightbulb is just like a horror scene

    69. LazyBunnyLyn

      Somehow you looked edited in

    70. Junior Mints

      Black Rooms Matter

    82. Austin Hillard

      What do IR or thermal cameras see

    83. Salty Scrub

      All I'm saying is, maybe this paint shouldnt wear hoodies.

    84. Mike DaChincheka

      I did the same thing to one of my walk in closets. The difference is I bought a pack of small glow in the dark stars, a pack of medium size glow in the dark plants and last a small black light. If you guys are into outer space this is a super cool project. For some strange reason placing glow in the dark stars on all sides of the walls, ceiling, floor, closet rods and door will result in you not being able to hold your balance. It is super cool and it will leave you feeling like you are really floating in space. Fun Tip: walk inside the middle of the empty closet, close your eyes and have a friend or family member turn on black light for 20 seconds then turn off and quickly close the door.

    85. Ryan Lopez

      I'm wondering what will luminous stickers look likes in that room
