    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.

    It's nice of Adam to let an autist in his workshop.

    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.

    I have a question, couldn't they have just left the pole on the dama because they were going to cut a hole in it anyway?

    there is nothing wrong with this toy, it works just fine. there are kendama tournaments and kids and adults have no problem catching it

    you should drop Patrick Adair Designs some of this material
    i would LOVE to see him build a ring out of it.

    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!

    This reminds me of when I was a kid working in my dad's workshop. He had a lathe that he used for carpentry type projects. He also worked on vehicles and repaired pretty much everything around the house. I feel like I took those years for granted.

    I love the fact that they can simply use a 3D printer and make that thing in like 1 hour

    Did anyone notice the perfectly round ball, with a hole in it on Adams machine?! I know there is a number on it and it’s a billardball, but still. I would have jump the fence, Where it Was lowest and grabed that Ball!

  • FilterYT
    FilterYT 13 days ago

    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.

    Should have just milled a space for a bearing into the original and rubbed wax on the surface of the stick and inside of the ball.

    I can remember when I was 10 years old and my dad made my brother and I each a pair of nun chucks. I will never forget watching my brother wrack himself multiple times. Back then it brought tears to both our eyes. It still brings a smile to my face. I was smarter I tried very hard to actually catch the chuck in my hand. My brother had knots on his head, face, elbows, knees and other places. Oh the things you can make out of broom handles... Thanks Dad for the very precious memories. I would love to see him make a pair of clackers. Those things were super dangerous and funny if you were watching someone else. I whacked my self in the eye with them once. I had a nice shiner for about two weeks.

    shouldnt the rotation axis be more stable if the knot is higher, almost at the periphery, instead of in the middle? because then the center of gravity is below the knot to keep the axis straight.

    I'd like to see a redux version of this episode where they have a kendama professional/expert come on and critique the choices they make to the modifications. I see why they did what they did, and it's fascinating. But any experienced kendama player is likely cringing at some of their choices when there is clearly no insider know-how behind them.

I was enthralled watching the whole process, so thank you so much for doing it and filming it so well. That is what I call quality content.

    As an avid kendama player and collector... I think they lost sight of the purpose of playing a kendama. It's a hand/eye coordination toy, that's meant to be difficult to master. Spinning the tama (ball) is one solution to one facet of playing the kendama. So designing a kendama to accommodate that one trick, seems silly. Granted, I love these videos and I'm just being a stickler. I learned a lot and will value the information, regardless. Stay classy!
    Side Note: Although variations of this game exist all around the world, the Kendama was created in Japan during the 19th century. It's origins stem from the French game Bilboquet that was played as early as the 16th century.

    I'd imagine you'd want to extend the 'ken' to the length that ideally leaves the balance point where you rest your fingers on the handle. That way the 'dama' can be pulled straight up regardless of the micro-inefficiencies your arm might make on the pull up... the handle will stay balanced and level with the ground
