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.

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.

But can it say the N WORD ?

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!

Everyone always thinks about a black paint that can absorb all light. BUT WHERE A WHITE PAINT THAT CAN REFLECT LITERALLY EVERYTHING, I WANT MU ROOM TO BE LIKE BARRIER IN UNDERTALE
