    Sorry Napkinheads, but the solid shown from 0:18 to 0:24 is not a proper mathematical "napkin ring." It shouldn't have flat faces on the top and bottom. That's a mistake I missed in my rush to export this episode before my flight to Montreal this morning :( But I'm glad to be in Montreal! I'm here working on an episode about the power of suggestion ...

      Technically, the math involved here is only at the level you'd learn in a highschool trigonometry class.
      To be sure, it's not immediately intuitive and even if you knew how all the math involved worked that's not a guarantee you could figure this proof out on your own; but if you really would like to learn more about these kind if things, the math involved would not take very long to learn. I don't know what your education level is, but a single college level algebra class would likely cover more than anything you'd need.
      As far as Vsauce videos go, this one has a fairly low bar for entry and I'd encourage you to maybe pick up a book or two talking about trigonometry if you don't feel like taking a class. Knowing about angles and some of the more involved proofs for shape structure function has helped me a lot to intuitively understand my surroundings in every day life.
      It has certainly helped me to visualized objects better and increased my spacial understanding.
      I wish when I did trig back in high school I paid more attention, maybe learning Calc would have been easier if I didn't botch my basics.

      @FireBeam BRO what? Yes I understand. The equation proved that the size of the sphere is not relevant, if they share the same height the volume that it would take up is the same. This guy is saying "oh he took more from the bigger one", but he needed to take more from the bigger one in order to get a napkin ring that is the same height. This concept is really interesting and if you felt this was stupid, then you should have just closed the video.

      I love this kind of video, it captures that feeling, that after looking at a problem for a while, and solving equations, you find a fascinating, counter-intuitive fact. In this case, the sphere's radius cancelling out.
      And all of the math used in this video is simple, high-school (or even middle-school)-level math - Subtract terms from both sides, square or take the square root, use the Pythagorean theorem, BAM, you got a result

    Hello there! I just finished watching the video on "The Science of Awkwardness" by Vsauce and I must say, it was truly fascinating. The way the video tackled the subject of awkwardness from a scientific standpoint was very enlightening.
    I found the part about "The Spotlight Effect" particularly interesting, as it explained why we often feel like we're being observed or scrutinized even when we're not. The experiments and studies presented in the video really helped to drive home the point.
    Overall, I thought this was a well-made video that was both informative and entertaining. It's great to see content creators using their platform to spread knowledge and understanding about the human experience. Thank you for sharing this video with me!

    And actually, if you go through all the calculus (which I did because calculus = fun), or if you just make the insight that h=2r if the height of the napkin ring is the same as the sphere (and therefore the same volume), you can find out pretty easily that the formula for the volume is simply (pi/6)*h^3.

    I saw this video a long time ago but never forgot it. Now I’ma math tutor and I bring it up with my students every so often. Although I did forget this version of the explanation, and so I’d have to use calculus to prove it, which I imagine must have confused the younger kids.
