I made something blacker than Vantablack! I show you what it looks like when you shine the world's brightest flashlight on it and also a super-bright blue laser! Then I talk about blackbody radiation and how perfect blackbodies are perfect absorbers and perfect emitters.

    It was nice to see the demonstration with the laser, it was a bit hard for me to understand how black it was with the light, but the laser really showed me how impressive your work is

    I always liked the idea of having a haunted house made using this stuff. Just a giant single room, with this stuff painted on the floor, ceiling, and all the walls. Then have people in suits painted with this stuff, just running around torturing the guests, essentially invisible.

    If a sheet of glass was put in front of it. Would it make the most colour accurate mirror in the world? Also. Wouldn't this be the perfect colour for solar panels?

    Action Lab: “Pretty crude way of measuring how much light is absorbed.” Me: confused, not understanding how he calculated the “crude way” to begin with, scared thinking about what the more-complicated way would look like

    I love the way you trick a lot of people into actually learning real science. Top man!

    I wish I could have a suite in Vantablack. This would be so awesome.

    For the first time ever on seeing any Youtube video, I clapped like crazy as you opened the black box. Thanks for this.

  • @maxnemo1643
    That's amazing! How did you make this substance? Is it a secret?
