@@Sheepy007 while making a (true) realtime graph would be hard, just recording the rpm in intervals of a minute or 30 seconds would be good enough Also I believe he already has made graphs for drag so I would guess for that he needs rpm data, so he likely already has a system for that
just watched this 5 times in a row, I am confidently confirm that this is indeed a spinning top - & yes, if you look closely, it is indeed spinning.
btw your record is the coolest one to hold imo, its weird that you have to be the one that adds so many stipulations to your record title - when every other world record (like the battery powered, or the one w/ a shroud) are the ones that are stepping outside of what would be the traditional perception of what a 'spinning top' even is.
Congratulations, James ! The disciple has beaten the master ! I am making some decorative tops now, so your record will be safe for at least some months. Then I could decide to beat it. It could be a nice competition.
I'm planning on doing this experiment but I suspect above about 3-4000 rpm it will become unstable and hula-hoop with increasing radius until it falls off the base!
A while back I commented here estimating an overall revolution count of 1 mil. This was _wildy_ incorrect. I screwed up: - the assumption that the decay is a simple exponent. Checked an rpm value around halfway it's fit was way off. - 3 (!) out of the 4 values I had to plug into the integral. But I wrongly assumed the function I need to use anyway so this just added insult to injury. My physics teacher would be proud...
I think next step would probably have to do with improving the contact point I would look into some type of coatings Also I wonder how long it would spin in a vacuum chamber, my bet is 3h, what do you think?
You say; "...spinning in normal atmospheric conditions (no vacuum or shroud)" . Just a clarification: my shroud does not change the normal atmospheric conditions at all: it only changes the direction of the flows of the air around the flywheel, interrupting the viscous pump effect. For this reason my tops with a shroud spin longer.
This one started at a little over 2000 rpm. If I doubled the rpm to 4000, it would only spin for around 10-15 minutes more. This is because the rate of rpm decay with angular velocity is quite exponential. The top loses about 5% of its rpms every minute throughout the spin.
I think the indicator paint is causing it to wobble early here. You can see that the wobble follows the gap inthe indicator fluid or whatever it is by 90 degrees.
It's not the paint.. Tungsten alloys have not homogeneous density, so, even if the machining was accurate, these tops are almost always unbalanced, out of the lathe. I think that James tried to fix the unbalance by shifting the tip a bit, (by filing its sides), but this made the tip off centered, and this is why the top wobbles.
You would be surprised! Yes it takes a long time, the rpm gain over time increases decreasingly. To start with it picks up speed fast but to get it a bit faster to its max speed takes longer. I usually measure the speed with a tachometer to ensure I am satisfied with the speed I start with.
Do you sell tops? It would be cool to use tops in the ways people used to use sand timers also. I would really like to gift one with these to a family member next year and clearly your machining and finish quality is ‘top’ notch. It wouldn’t even have to be the 1 hour+ one I would happily by an older model, if just a model that doesn’t your the earth to source and machine. Alway love your videos
I don’t have anything to sell right now but trust me I’m working on it🤩 Hopefully by this summer you will have the chance - due to high demand and low supply it will probably be an auction format for sake of fairness. I do not wish to give away older models as they show the progression of my craft over the years and hence have sentimental value. Thank you for your interest and for watching my videos :)
Yes I made all of these :) What are you making the top for? The best design will depend on how you are starting it and what other rules you are following. Generally though, a dense flywheel/mass concentrated outwards, a hard tip and harder base are a good starting point. But balance is also super important!
A thing of true beauty Happiness = Happiness + 1 On the order of 70,000 rotations, correct? First phase reversal I noticed was between 1650 and 1710 The small dot at ~930 behind the plane of rotation, left side, allows visual tracking of the slow and stately precession
Possibly if I practiced, however this top is not designed for that launch style. Likely I would end up pushing the top off the base, causing some damage. Palm tops require even longer spindles :)
even though i want to believe that you broke this record there seem to be several cuts in the video one that's easy to spot is at 1:50 on the timer (5:10 of the video.) from what i can tell there is a reflective bit at the stump (most probably to measure rpm) this together with framerate appears to be steady for a few seconds there. then it switches instantly to black. thats odd. please find a video editing/production reason why it appears that way.
I can assure you this video is real! I added the text and adjusted volume levels etc in CapCut which involved splitting the raw video but this should not have impacted the timing at all. I suspect this is an artefact of frame rate interfering with the slowing flashing of the black marker (start of the spin is about 2095 rpm so 35 revolutions per second and this would decrease throughout the spin). On my iPhone, the black marker is flashing rapidly, but on TH-cam, at the timestamp you gave, it appears quite motionless so it may also be a video compression/bitrate thing. It does look odd for sure haha.
I believe that the video is real. James learned from me how to make tops in that way, I am making them for years. A brass top with that design can spin for up to about one hour. No surprise that a tungsten top can do the same, he should be able to do even better, given the density advantage of tungsten over brass.
There isn’t haha that’s a frame rate issue when exporting to TH-cam. The black mark is flashing around 30 times per second and is slowing down continuously. However the frame rate I exported is a constant 60fps (I think) so it doesn’t always line up - hence the jumps. This effect should disappear as the top slows :)
Great achievement! I don't know about the rules you've set yourself about how to spin it, but have you tried spinning it with your palms or forearms? I'd be curious if it could reach higher speed then (although stability would be a problem)
You are right about stability, furthermore, the stem isn't really long enough for this style of spinning! So it would take a lot of practice to be able to launch the top without having it topple off the base :) I'll try this in a future video!
The record may specifically for spinning by hand, yet I think the decay from the air friction might make it not that much longer since it slows exponentially more drastically at the beginning.
I'm currently working on commercialising this design on a very small scale (maybe 10 tops). Then I would be quite interested in the single-twirl category, which lends itself to smaller tops and hence is more appealing to the edc community and a wider market ;) I'm open to other projects for sure but I feel there is room for improvement so I will keep working on my mathematical model and look out for new materials etc :)
@@Skinnamarink. I have been thinking about that, one idea is I auction them off on ebay, one a week for 10 weeks. That way hopefully you can try multiple times to get one :)
You could still beat your current record if you didn't start off the spin by hand. No doubt this isn't a very controlled way of launching the spinning top, you cannot control for initial KE and last but by no means least, you'll induce micro dilineations at the contact point every time you spin it because you'll never spin it perfectly and always push it laterally, essentially "scratching the surface". Not sure how much time this would get you but you'l definitely see some improvement.
Yes this is true, perhaps I should find another similar but more scientific challenge to aim for now that the 1 hour barrier is broken. In this case using a tool to start the top in a controlled manner would be fine. Or perhaps in my testing I should always use a drill etc and only use my fingers for record attempts ...
@@hiper_tops maybe build something similar to how some spin tops are launched, using a string or some way of transfering linear to rotational velocity? I mean you definitely aren't limited by the lack of tools or engineering skills 😁
I am so happy that you uploaded the full spin...
What happens at roughly 5:10 ? It looks like a jump cut (The frame when the onscreen timer changes from 1:50.31 to 1:50.34)
Good catch. That really does look odd. I think the timer jumping is not that strange though, it seems to always jump in 3-5 ms increments
And I thought I had a good top that could spin for over 2 minutes...
This one takes longer than that just to start 😳
I have no clue on how to do this but it would be really cool to see an rpm graph of this
I believe there is no feasible way to do this, without compromising it's spinning quality.
Maybe with something like a laser measuring set up.
@@Sheepy007 while making a (true) realtime graph would be hard, just recording the rpm in intervals of a minute or 30 seconds would be good enough

perfect timing... I'll sleep well with this in the backround.
I have a feeling that Michael from Vsauce is gonna love this

Wow! I see you have already hit back in a few weeks!
@@caiomotta8910 , I had some free time so I did it...
just wondering what would happen if you spin it to 10.000 rpm with some kind of motor
I'm planning on doing this experiment but I suspect above about 3-4000 rpm it will become unstable and hula-hoop with increasing radius until it falls off the base!
Inception theme in my head....
Have you tried accelerating one of these with compressed air to ramp up the RPMs? I want one!
A while back I commented here estimating an overall revolution count of 1 mil. This was _wildy_ incorrect.

@@varisleek3360 I won't take the time to get several rpm samples at different timestamps to find a properly fitting decay function. But be my guest.
Great job. I can’t wait to see you smash this record too.
I wonder if hardness of the material used at the tip and base matter. Maybe try tungsten carbide tip and base next time.
What if you did the same test at high altitude to reduce the air drag? You could even go so high that the human would need supplemental oxygen.
Reminds me of the part in "sum of all fears" where they hire eye glass lens people to file the uranium sphere and round it out perfectly
Fascinating, and beautiful. Congratulations 👏
I think next step would probably have to do with improving the contact point I would look into some type of coatings
Also I wonder how long it would spin in a vacuum chamber, my bet is 3h, what do you think?
pretty sure you can break this if you spin it with a wire or is that illegal
You say; "...spinning in normal atmospheric conditions (no vacuum or shroud)" . Just a clarification: my shroud does not change the normal atmospheric conditions at all: it only changes the direction of the flows of the air around the flywheel, interrupting the viscous pump effect. For this reason my tops with a shroud spin longer.
How long would it spin if it's spun up with a high powered air compressor
This one started at a little over 2000 rpm. If I doubled the rpm to 4000, it would only spin for around 10-15 minutes more. This is because the rate of rpm decay with angular velocity is quite exponential. The top loses about 5% of its rpms every minute throughout the spin.

Is it really necessary to spin the top for over 3 minutes? Can you not get it spinning at maximum rpm’s after like 10 seconds?
You would be surprised! Yes it takes a long time, the rpm gain over time increases decreasingly. To start with it picks up speed fast but to get it a bit faster to its max speed takes longer. I usually measure the speed with a tachometer to ensure I am satisfied with the speed I start with.

Rather interesting almost sub-aural ASMR as well, I think.-- truck? at ~27:05 by the on screen clock : )

Much bigger and longer tip vibration starts at ~35:40
The ending, after 1:00:00 and beyond is mesmerizing
Yes that's about right :)

seems so
impressive
James, I sent you an e-mail from the ITopSpin forum.
How many rotations
He said 2095 rpm and it spins for roughly an hour so work it out

Very good.
Have you considered using a string or ribbon to start a top.
Id imagine that allows longer spins
Is there a record for that category ?
The record may specifically for spinning by hand, yet I think the decay from the air friction might make it not that much longer since it slows exponentially more drastically at the beginning.
