Adam Savage and Vsauce's Michael Stevens Build a Kendama!

  • Published on Aug 11, 2017
  • See Adam and Michael this fall on their Brain Candy tour! For tickets and info, visit
    Adam is joined by Vsauce's Michael Stevens for a special One Day Build in the cave. Michael has recently taken up playing the Kendama, a Japanese cup and ball toy, and Adam helps make one from scratch that helps optimize his play. This build engrosses both into topics of machining, knot tying, and geometric conundrums.

    Michael, spinning the dama is considered cheating if you ever want to get into tournament levels. It's like having training wheels on a bicycle - good for beginners but shouldn't be used once familiar with it. ;)

    Love it when these two just _get_ each other like when Michael's talking about spinning the dama and Adam's just like "ooooh shit it's a gyroscope yeah yeah got it"

    CORRECT TERMS: Machining on a Lathe is called "turning". Lathing is the stuff that plaster walls are attached to. Parts turned on a lathe can be called by their name but in general are "turnings". No such word as "Lathe ing"

    Couldn't you just take of the white part, rotate it 180 degrees so that the big cup and the small one change places, and put it back on? Then it would be the same chirality

    A machine with no brain and that is strong enough to throw huge chuncks of materials across the shop and through your head is a very dangerous thing indeed.

    Can someone get on the whole "find the dark skin setting byte in the exe file" as soon as they roll out the new UI? eyes can't handle the light skin and yes it's even lighter than the current one...also I'm poor as fuck.

    • BenJoe72
      BenJoe72 17 days ago

      2 things:
      1. You are right. I'm not poor, I have some place to live and food to eat. I just don't have the money to subscribe for Unity Pro. Over-exaggeration is a thing.
      2. Why did this comment show under "Adam Savage and Vsauce's Michael Stevens Build a Kendama!" (Tested) video instead of "NEW UNITY UI?! - Unite 2018 Recap", (Brackeys) the one I posted it on? TVclip...hello?

    When I learned to use a lathe in high school and I got caught sanding the wood while spinning, I would've been slapped. It was in the 80s, and back then it was okay to do that.

    I can't believe Adam still has all his fingers. Watching him repeatedly reach in near the moving lathe chuck with stuff/to pull stuff out made me cringe. I speak from experience when I say you get away with it... until you don't!

    its absolutely adorable that michael has virtually no machining knowledge. Idk why but I expected michael to just be some omnipotent force in the universe.

  • Nolan Patterson
    Nolan Patterson 23 days ago

    I love the way that Michael knows a little bit about machining, but still has enough to learn from Adam, unlike when Adam is with other pros who also know everything about it... I also love how Michael learns something about the lathe, for example, then uses that new found knowledge and explains the physics behind it. All in all the chemistry of these two, who are geniuses in different fields, merges almost seamlessly for this project. I think this is just about the greatest video I have ever seen.

    Fabulous is in the mind of the beholder. These two have a symbiotic exchange of knowledge going on. And when one has a hole in his knowledge, the other fills it. The process is interesting to watch and profitable to learn. Thank you, guys.

    What a great video guys! Thank you for sharing it. I do want to make one comment though. Admittedly, I'm not sure, but it seems to me the shorter string would actually make catching easier...
    This video brought many pleasant flash backs for me back in high school when I was introduced to the machine shop. Again, thank you! :-)

    To all watching... Adam is what you'd call; a professional... (plus he wears glasses) so make sure you wear the appropriate safety gear whilst opperating your lathes/bench drills etc lol. But seriously, take care out there people. We'll need you to re-build the world soon enough ;)

  • ehok121
    ehok121 26 days ago

    The Problem why you cant catch it right is cause you dont use your knees! 0 Velocity isnt needed and will make it look bad.
    Use your body and it will look fluid. Kendama is a sport which needs more then just the Hands. ^^

    Why not build in a really strong electromagnet in the cups and give the ball a metallic surface, when trying to catch the ball in a cup, you'll press a hidden button on the handle and activate the magnet :D

    This is so soothing to watch! I'm only halfway trough, but the fact that this is edited in a way where you show all problems as you encounter them and not "This is the point where we got into a bit of a bind, but after some thinking..." makes it really down to earth and sort of... inclusive? Sorry for that way too long sentence there. I realize this video is almost a year old, but kudos from Sweden
