DIY Euler's Disk spinning for 3 minutes and 36 seconds
This is a ring made from polished Tungsten Carbide with a brass weight pressed into it.
The reflexion in the mirror looks like a face.
It makes quite a strange noise.
It's running on a 7x magnifying bathroom mirror.
I removed the back side of the mirror and glued it to its housing with super glue.
Then I poured plaster into the hollow housing to make it rigid and heavy to prevent vibrations.
At the beginning it spins like a normal spinning top.
The rotation speed is slowly going down.
But then ...
...the frequency is slowly rising again.
It starts the "spolling" motion (spinning and rolling) that is typical for Euler's Disk.
Tungsten Carbide is a very hard material. It is used to make cutters for lathes and milling machines.
In combination with the glass, which is also quite hard, there is very low rolling friction.
Riding a bike with tires pumped up hard on a street made from concrete is easier then with low tire pressure over a lawn. Right?
Tungsten is also very heavy. It's sometimes used to make fake gold ingots.
The heavy tungsten and heavy brass store a lot of potential and kinetic energy.
But unfortunately rolling resistance and sliding friction are proportional to the weight.
But air resistance is independant of the weight so it's better to use heavy materials.
On the moon with 1/6 of the weight and without air it would run much longer.
Or on Planet Pluto where it has only 1/16 of its weight!
YES, I KNOW, that Pluto is officially now longer a planet. But for ME it will allways be a planet!
It's just not fair! Imagine you have been respected for over 70 years as a true planet. And all of a sudden you are called a "Dwarf planet" !!!
Dwarf planet !! Couldn't they at least have named it "Planet of short stature" ?!?
Did you watch the film "Falling Down" with Michael Douglas?
It shows what will happen when someone is no longer respected!
If I was Pluto I would leave my orbid, set the course for "Planet (!)" Earth and crush these arrogant earthlings. (except the brave people of Illinois)
Sorry, I'm afraid I have become a little bit too emotional !
Isn't it strange: Pluto has such a good reputation, but the metal that was named after it is rather unpopular.
Plutonium !!!
Okay, enough now, you seem a little bit too chatty to me. Now let's concentrate again on Euler's Disk!
The wobble motion is very fast and getting faster at the end. But the rotational movement (indicated by the arrow) is getting slower at the end.
This is what you don't see very well when watching the commercially available Euler Disk with its fancy holographic stickers on it.
For all skeptics: No tricks withs hidden magnetic stirrer under the table, because the disc is non magnetic.
But counterfeit money looking like copper and being only copper plated iron.
What you see in the middle is grease from my hands spreaded to a circular area by the motion of the disk.
Plaster (lacquered)
Yes, I should have cleaned it with acetone before showing this video to you and other honorable members of the scientific community.
And I did clean it and wanted to make a new video! But the clean version was spinning for only 2 Minutes!
I tried different types of grease and oils.
I even tried Lithium grease with Molybdenum disulfide (MoS2) !
This is that type of grease that would make normal grease slip, fall to the floor and break its leg.
Didn't work as good as human grease from Latheman666.
Or should I say superhuman grease ?
YES! I have a shower every day !!!
Wrong side. Brass is not hard enough.
Even thin paper will stop the disk.
A long hair donated by a young lady. I simply can't afford anymore to pull out one of my fewer and fewer own.
came for a euler's disc. got it and a rant about Pluto. I gave it a like.
Same
I love how the commentary gets progressively more aggressive as the disk speeds up.
Euler's Disc = 10/10 well done!
Commentary = 17/10 YOU MADE ME CRY with laughter xD
I like how the commentary started off with the Euler's Disc and ended up with a rant about Pluto.
-C’mon Jerry, say it again!
-Hmm, Pluto... is a planet.
*Plutonians rejoice*
Question.
Who the hell rants about the whole pluto is a planet debate in the middle of a video about a euler disc record?
why not
Also: Remove all the blank lines between lines. Don't start a new line for every sentence.
It's not a "transcript" (no one talks in the video), it is just the text that is displayed in the video.
Jerry Smith
I was just going to point that out. Good job Niko, have a pancake.
@@ryanshea94 beat me to it
Great! I wonder how many people skipped this video, thinking it would be boring to watch a disk spin for over 3 minutes, and missed out on the hilarious commentary!
true
a bit of resistance starting at 2:54, i'm sure you could level out the brass a few micrometers and get a longer spin. still the most respectable DIY Euler disk ive seen yet!
Dude Falling Down is one of my all-time favorites. I burst out laughing when that came up!
The Pluto bit was hysterical. I needed that laugh.😂😂😂
Mirror is wasting energy because its not stiff enough. All the sound is evidence of wasted energy. Great job. A new record.
I'd absolutely love to buy one of these.
Finally, some one with a decent starting spin
Immediately subbed after the special bonus feature ended up being about Pluto. Anyone who thinks this is nothing a but a skippable video of a disc spinning is truly missing out.
Pluto will always be a planet to me. Period.
The Pluto rant! I love it!
M Ross - It got even better with the reference to Falling Down, especially since that's what the disk was doing for three minutes.
I love Pluto too!
I mean did you see those images of how geologically complex and diverse it is!! It's one of the most facinating bodies in the solar system gosh darn it!
Great. Perfect way for me to kill off the first day of the New year...watching your Euler disk fall down.
What a charming quixotic quest.
Really nice job! I love that movie BTW. One of my all time favorites.
Yes! Pluto will always be a planet to me also!
Cant. Stop. Watching.
Pluto be like: 5"9
Every other planet be like: 6"1
To be fair, I think the spolling starts around 1m 15s, so that would give a 2m 15s spoll.
Anyway, love the noise it makes towards the end! :)
That was very satisfying
This was awesome. Very entertaining. Thanks
Pluto is a planet in my heart
No one:
The aliens landing in 2020: wewwewwewwewwewwewweww
I see the birth of a new toy... and Mattel handing you a fat check!
Damn, that spins for a long ass time
They rising pitch with the dramatic swoosh at the end reminds me of the gravity waves emitted by two black holes spiraling into each other.
Very interesting, like the commentary :)
Conservation of angualr momentum, but it only gradually shifts here. Hence, 3.5 minutes before it settles. A true balancing act of forces at work in physics.
Bravo!!! Well done and presented.
Once you said "planet Pluto" the first time, I just had to like this video.
I love the Pluto ramble
Wow ... Somebody's been a snortin off that mirror....lol.
3:00
Sounds like my PS4's poor old fans kicking in during Red Dead 2.
Im totally with you on the pluto issue
This Euler's disk seems to be some sort of mechanical oscillator, like a pendulum. If that is the case, you have potential energy being converted to kinetic energy and then back again.
Very amusing presentation. Did you write the opening credits for Python's "Holy Grail"? ( A moose once bit my sister).
I'm almost 60. Since I was a kid I would look at diagrams of the solar system with all planets rotating on one disc and Pluto having an inclination in its orbit. And I always said something is WRONG here. When they said Pluto is not really a planet my life long question was answered once and for all. For me Pluto was always an enigma and never a planet. It just took scientists some time to see it.
WoW... I think I'll stay home tonight and see what is next on this channel.
I love this guys text commentary
Take a tab of acid with your friends and let the arrow decide who has to eat a habanero. Nuclear suspense
the fidget spinner of its time
Doctor: sorry but you will die in 4 minute later
Me: ok, can i borrow your phone
Doctor: yes... Why?
Me:
Have you tried polishing the surfaces ? Maybe that could increase the time even more ?
Pluto is a planet again.
Very cool. What would happen if you did this inside a bell jar with a vacuum applied? Would the absence of air make a noticeable difference?
Steve Miller no, friction has the most influence in slowing the disc down.
@@mouseutopia i‘m 5 years late but there‘s a different video of a commercial disk in a vacuum chamber and it ran for 2:38 minutes while the normal one ran for only like 1:35! so yes, it does make a pretty big impact
Make it 10 hours put ASMR on the tag and you sir got yourself a viral video.
Should be called crazy lathe mans machines
Eris is objectively the best dwarf planet.
revisiting your video, it's so cool!
Pluto will ALWAYS be a planet to me.
And it sounds better than Uranus.....
Reminder that pluto is smaller than our moon and is at most an unusually round astroid
I once had a marble table and real ivory dice. It's an amazing display if you get the chance. Try a "liquid metal " base if you get the chance.
The commentary. Love it
I'd like to see it under strobe light.
Did the arrow really rotate that slowly, or is there some strobe effect from the 60 Hrz light source?
Yea this
I own a Euler's disk myself, and yes, the actual rotations of the disk become fewer in frequency as the frequency of the wobbling increases. The rotations slow to a crawl towards the end.
Thanks! That was actually a lot of fun. :)
Have you seen the videos of a Euler's Disc in a vacuum? It adds a full minute to the spin time.
Lols your comments is always the best..... Love how u narrates...
i think it's the amount of grease.
like in ball bearings if you remove the thick grease and replace it with some thin oil or leave it dry, when you then spin it, it will continue rotating for longer than with the grease.
This mostly true if there is no load on it.
Try with some thin oil for sewing machines or watches. maybe kerosene or petroleum.
+TheMmmaaaggg13579 Yes, you are right.
+Latheman666 I think you should also explore waxes. it might not be lubrication you're after, but traction!
That's a great idea! I will try it.
the more energy lost = less time moving
so if you were to perform this in a vacuum the it would last even longer
I was just reading about the experiments that have been done in this area, and it turns out that air resistance doesn't make that much difference!
In the 1960 movie version of H. G. Wells' "The Time Machine", star Rod Taylor arrives in the distant future - in AD 802,701 - and enters a ancient, crumbling museum. All the books are turned to dust, but on a shelf there sits something that looks very suspiciously like the apparatus Latheman666 has made.
Turns out it is some kind of holographic movie projector known to the locals as one of the "talking rings". The disk is spun up and as it continues to spin a movie projected onto the air tells of a centuries-long nuclear war in the distant past. As the disk winds down and comes to a stop, so does the history lesson. Obviously, the spinning disk provided power to the projector.
I suspect this Latheman666 read of H. G. Wells' travels in time and went to the future and stole that very same apparatus, only he has not succeeded in getting the movie to project no matter how many times he spins that disk, but he just keeps on trying. That is what he really wanted to show us instead of a boring disk spinning for 3 1/2 minutes.

Euler had a lot of time on his hands !
Falling Down is a great movie. "I'm the bad guy?"
6:11 this is the kinda stuff that makes a lot of people anxious
I appreciate this grease man
the ramblings of an Euler disk
Pluto is a planet....fight me!
Máquinas fantásticas.
put this in a vacuum chamber and you have a new world record
Nice trick, try cutting off the head of a pin and glue it right in the center of the metal to make it more difficult to settle down...
Listening to the sound of this video, I can't help but think it sounds very similar to the recent (sped up) recordings of Black Holes merging - detected by the LIGOS detectors in 2016
Awesome. You crack me up!
I did that with a hockey puck on a glass counter in a trophy store. It didn't last as long but made great noise and annoyed the store owner.
Love it want one
Gotta admit i like the commentary, even if some of it is relatively flat.What i was wondering, since i don't have access to materials of this quality myself, if you would consider doing another video with a coloured gas or smoke, preferably not too much denser than normal atmospheric air, to make a good visual demonstration of the displacement of air around a disc; I'd love to have a decent visual comparison of the normal air spin-down and the visualizing gas/smoke spin-down, perhaps side-by-side, though of course you should do what you feel like doing regardless :)
dude you could use one of those as a spin the bottle!
I FUCKING want one of these. Just to sit at my desk and let it go.
I wonder if this is significantly different enough from the original patent that you could patent this, Because the original patent is a single metal disk I think not too different metals... It is true that there's a curvature on one side and not on the other but i think that is standard and how that works and that might be part of the patent i don't know.
did not planned to watch this video thoroughly; 3,5mins of Euler's disc, meh.. but your narration have amused me! :D
Please see "standupmaths" and his video on the maths behind Euler's disc. He had a high speed camera setup to capture his disc and it was cool.
Yes, thanks, it's a good video. I've seen it already.
Justice for Pluto!
Next step: start it running, then place a vacuum jar over it and evacuate it as fast as possible. Then experiment with different density materials in the absence of air resistance.
Would it run longer if the disk was bigger, aka more potential energy and higher starting point
everyone be asking "why is he ranting about pluto?"
when the real question is "what the hell is tungsten?".
You could make it go even longer if you're able to put it and spin it in a vacuum
And not one comment about the non-Ferris penny being magnetic.
Last sound make me crazy.
Sounds like the intro to Harder, Better, Faster, Stronger
Song by Daft Punk
3:08 "(except the brave people of Illinois)"
Me: huehuehue Chicago time!
Liked and subsribed @2:30. PLUTO FOREVER!!
Imagine this is the totem of DiCaprio in the movie Inception
cool!
Ceres was considered a planet for 50 years before being reclassified but you don't see people crying about it
There is no reasonable definition of a major planet that includes Pluto without including several other dwarf planets
Dont worry. As soon as they can, I am sure they will put a Mcdonalds, Dollar store and a land fill on Pluto
low tire pressure cases the tire to flex giving more surface area giving more traction
what would happen if you used the tech that lets you make things hover if you make it really really cold, surely that would eliminate some friction.
use a Teflon coated surface (eg non stick pan), you should get longer still
