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.

    Its painful to listen to these two try and beat an "intelligent" conversation out of something that is not complex.

    i didn't really browse the comments, so if someone has already mentioned it.. sorry, but if you tilt the ken, just slightlyup, and again, use your knees. it's much more simple/consecutive.

    BCY Halo used for bow string serving may work well as it has a slick finish and it will probably last a lifetime for this application. Its a blend of Spectra/Dyneema and is available in precise diameters from .007" @ 35lb breaking strength, up to .030" with a breaking strength of 215lb. BCY 3D may be another option, but it has slightly different properties and I don't feel its quite as slick.
    Here's the manufacturers website

    How does this video only have 2.4 million views? Every day, when I get home from work, I queue up that day's videos from my subscription feed, and play it on my Chromecast. And more often than not, once all the videos in my queue have played, TVclip autoplays this video. After close to 2 years of watching TVclip every single day, I've noticed it at least a couple dozen times. Has anyone else noticed this?

    if you want to change the handedness of your kendama, couldnt you just take the cups off the handle and turn them so they face the other way?

      The ONLY reason I have been reading these comments is to see if anyone else was going to realize that. You and I are like the little girl that said "let some air out of the tires". Wonder how many even know that reference.
      Thank you for being willing to think the simple, obvious-type answer might be the easiest and correct answer.

    Michael asks questions that most machinists would think are dumb questions, but the answer is always something that we all have just learned to take for granted and never give a second thought.
    "what makes it a grippy material?"
    "so a mill is like a vertical lathe?"
    "why dont you lathe vertically?"
    this was such a great video, Michael and Adam aren't good at getting things done quickly but their conversations are wonderful.

    The drill chuck is likely out, you're correct, however that doesn't affect an edge finder. The edge finder tip rotates about the center of the spindle regardless if the body is out or not. Similar to to a dial indicator if its in an arm and off center. That is why the edge finder is such an elegant, accurate, inexpensive solution. Usually within .0005" regardless of chuck runout.

    I am so incredibly jealous of Adam's workshop...there's probably more stuff than a Lowes and Home Depot combined, and I'm sure he remembers EXACTLY where every little thing is, and what it does. Everything has a purpose, I'd be willing to bet that not a single thing was bought 'just because'.

    At the end he was saying that the big cup was on the opposite side and it couldn't be changed. Can't he just pull the cups part off the handle and spin it around and put it back on?

    When you were talking about how deep the hole should go my opinion is if it is the same depth and the pole your trying to fit it on it would bounce more but if it was deeper it would stay with no bounce.
