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.

    You can still do a spike without spinning the dama it’s actually pretty easy but you need a little bit of practice 😊

    There is a Chilean game, like the Kendama, called "Emboque", similar motion in principle... but it uses a sort of "bell shaped" ball... look it up @tested

    A standard taper attachment for the cross slide can give the lathe the ability to cut tapered threads.

    You two should start a business using physics and engineering to make toys and fidgets better, and sell them. Honestly. I would pay a lot for something like that. Very impressive!

    They start talking about the napkin ring paradox at 6:50
    Michael walks him all the way through it and they both get on the same page.
    Adam's reaction as to why it is significant at 7:57 is pure mental anguish. Fantastic.
    I'm pretty sure that's how everyone feels the first time they hear about it.

    I play kendama somewhat seriously and seeing Michael pull the serato off of the spike (candle stick) portion of the ken would only irritate me, because i know if you were to try throw jugs or do any sara grip or tama grip tricks at all, the moment the tama and the ken make contact the serato (aka the part thats the big cup and small cup), it would only explode on you basically.

    Michael is a smart guy. But so is adam. And michael seems to be a bit condescending to adam, even though Adam is letting this man come into his shop, and building him a toy from scratch. Michael should try and be a bit more nice at times, and not talk down to the kind, lovable man that is adam savage. Plus adam is just too nice to bring this up

    12:03 work hardening is caused by the movement of dislocations within the crystaline structure not friction. The reason why the material gets brittle is because dilocations impede the movement of other dislocations. Why a kniffe gets hard is because the grain size within the steel becomes small and jagged due to the rapid cooling in the quneching process. Tempering is heating up the steel to just below the fcc and bcc transformation point to allow the grains to become slightly larger so the material is less brittle.

  • Jack Fletcher

    The ball is a tama, not a dama. Dama is a slang term for the whole of a kendama. Kendama is a term on its own, not a combination of ken and tama. Also, check out some pre-existing discussion on kendamas. The physics of them have already been toyed with by companies like KROM, PNW Kendama, CWCS, etc, and they've found that changing the balance limits the pool of more advanced tricks. It's like making a yo-yo that physically can't do more than go up and down.

    Lovely video, and a lot to learn about workshop techniques. But there really ought to be a "don't try this at home folks" warning because all the guards that ought to be on these machines to comply with modern safety regs are not there. A moment's inattention could lead to serious injury.

    I love your videos Adam! And Michael Stevens is an awesome guest for the one day builds. If I could make a suggestion though; make the voice audio louder because the background music is a lot louder. I have to turn the volume way up to hear your voices and then once the music comes in it's way too loud. I don't know if anyone else has that problem. It's just a suggestion though. Love your vids! Stay creative, and I will zee you next time!

  • FilterYT

    Maybe someone else suggested this same solution, but here is what I would try: carve a narrowish V into the top that the point of the V is at the centre of the mass of the ball, that way a sharp pull on the string wont impart a tilt to the ball.

    Sadly, during my childhood I was rarely exposed to any environments involving tools or machinery.. so I could never understand why so many guys (some gals) enjoyed camping out in their garage, shed, shop, etc. A few decades later, I can now reflect back and understand perfectly.. they are sanctuaries from endlessly nagging spouses, they can serve as stress relief outlets through constructive destruction (aka "projects"), and even cooler.. as Adam does at timestamp 14:30 .. create unnecessary and gratuitous messes without anyone caring.
