Some things about the video: -I tried first with base that was slightly (about 3mm) deeper on the middle but that made the top spin around the base since the side of the ball bearing that was on outer diameter had bit more traction and therefore generated force that drove the top around the base. -The bottom of the vacuum chamber bulges inward but I think that didn't affect a lot since the top was all around the base in the vacuum chamber in stead of staying at the just one side. -I think sharper bottom part of the top will help thing stay in one place with slightly curved base
If the spinner hits a bump, flies off and hits you in the shin...shattering the bone........can you upload the video to liveleak please? (If UA-cam won't allow it)
To hold the base center inside the vacuum chamber you could consider making about 5 or 6 little blocks cut to fit between the base and the chamber walls and place them around the base like spokes on a wheel.

Imagine a physics exam using "shitloads of" as an actual prefix. 1J = 1Nm 1kJ=1000J 1MJ=1000kJ 1GJ=1000MJ 1 shitload of joules = 23,6235GJ 1TJ = 42,3307 shitloads of joules 1PJ = 1000 TJ and so on
a mild concave to the middle of your base should help to center it and still allow movement for stability as well or you could make it like a contained gyroscope like the toy you can balance on a string...
The higher mass will cause the top to drill down harder. Friction will always win. If you make the bearing surface smaller, it will concentrate the mass into the base and scratch it up more. Then it will track along whatever edge it will find. This will throw off the balance and it will attempt to raise its center of gravity. Research "tippy top" and see what happens. There are a lot of complicated physics problems involved here, it is difficult to understand everything that will happen through observation. If you pursue it long enough and don't give up you will learn a lot. But if you do the research first you can save a lot of money and time. 1) RAISE the center of mass. 2) Use like-hardness surfaces in both the tip and the base. 3) Use dry ice to absorb heat from friction. 4) Decrease the overall mass and concentrate the mass you need to the outer diameter of the rotor. 5) Isolate the base from the vibration of the chamber caused by the vacuum pump to conserve energy during evacuation. 6) Consider adding an air damper between the pump and the chamber to reduce vibration caused by air escaping in pulses. 7) Don't paint the top. That will throw off the balance. At those high speeds, everything counts. - Former reaction wheel technician

@@Seedyrom247 Agreed, I was just kidding with this response due to the comments complexity. I figured a concave base would help then I saw this which melted my brain. But I never owned a keyblade stadium.
no? magnetic levitation. with strong neodymium magnets on both objects(or an electromagnet at the base as well) its a lot stonger than what bismuth can do. go ahead and levitate a 4kg object with bismuth lol.
Someone in the 90's attempted to build "mechanical batteries" out of a similar concept. I remember reading that it had magnetic bearings with a special design to reduce eddy currents. Very cool! Cannot wait to see the next iteration!
I really appreciate your efforts for your loyal subscribers! It was a lot of fun seeing this top made and tested, and I'm looking forward to the next one.
maybe when the vacuum gets under high pressure it pulls the bottom of the pot upward in the center allowing the base to wander toward one side(with vibration)
+simontay1984 also, the space station gets about 90% of the gravity that something on earth does. They don't lack gravity. They space station is falling, and so is anyone inside of it. There is really no point in space anywhere, that has zero gravity.
I've build spinning tops as child out of wood and lead. 1. Put you mass as far out as possible 2. put you mass as low as possible 3. Make the running point as sharp as possible out of hardened steel but softer than the running surface. 4. use a "watch glass dish" glued to a base as spinning surface. (steel on glass has a very low friction and glass is harder than steel) I turned plates with a stem in the middle out hardwood and plywood and screwed a poured lead ring on to the edge. Then I turned it round on my "lathe" (drill holding a screw on one side and a nail in a pice of wood on the other side) I started it with a rope wrapped around the "stem" and a special holder. I got spinning times around 40 minutes out of that. I think with proper construction more than 1 hour is possible and two hours in vacuum.
Very good idea! Depending on the amount of mass (and everything else) if you got 40 minutes by starting it with a rope that sounds like it was working well
I've build them 25 years ago. I have to buy the stuff and rebuild it. I experimented a lot as a child and reused everything. That's the problem if you haven't a lot of money, you disassemble old stuff to build new things. I used the lead in a steam engine as counterweight and fly wheel, in a remote controlled boat and u-boat, shoot with it with a steam powered cannon. I used up the lead for may other things.
Nice to hear, me too was a spinning top child, as a fifth grader :) I used a steel point on a mirror, my best top I built from an old tape recorder flywheel. It was perhaps 7cm in diameter and quite heavy. I had same method to start it but I had also a magnetic support which had three screw adjusted legs and it pulled most of the weight up. It rotated almost silently something between half an hour to hour, unfortunately I don't remember it any more. Most difficult was to make point concentric and to make surface of the top as smooth as possible with many layers of lacquer and sanding it.
Maybe make the surface you're spinning it on concave so it will center itself better. Also look into ceramic bearings, they should be harder and less abrasive than your hardened steel bearing balls.
Charles Britannia This does help recenter the top; however, it will also cause the bearing surface to track against the high outer side and induce an imbalance on the axis of the top.
I concur, a concave base with a very smooth finish should be ideal. The ceramic bearings are already a planned feature on future spinning tops, there is a video where he makes this thing on a lathe.
If we consider not only the exact words but also the tone of voice, then you actually translated it surprisingly well :D Ota se mun kännykkä pois siitä! ~ Take my phone out of there!
3 things: Use a bearing between your tip and the spiningtop it self. the top should be hard and pointy - hardened steel or if you have tungsten carbide needle. Mirrors. Yes, you can normally get quite decent magnifying bath-mirrors. glass is really smooth and hard, and has a low coefficient of friction with steel. And magnifying mirrors are slightly concave, helps keeping the top in the middle.
Know what my favourite thing is about watching Beyond the press? It's not Anni's legs, or even the cool stuff you come up with to do for our entertainment! Nope, there is a higher class of commenter on your videos! Many intelligent people with excellent things to say and hardly any keyboard warriors! Keep it up :)
Give it a try and use a magnifying bathroom mirror as the base. It works great for normal size tops and should also work for this one. I don't know how the glass would hold up to that monster though. But it would be cheap enough to try.
I'm a bit concerned about the tungsten tip though, the ball bearing already exerted enough pressure to deform the base. I would say the most important is a much harder base
I would think a tungsten point might actually start to bore into the base and slow it down faster, unless the base was also tungsten carbide or something extremely hard.
Exactly! Though it is possible to get tungsten carbide stock, the maximal width you can buy is around a cm. If they manage to keep it very steady that might just be enough for the center of the base... or the outer race/groove of a silicon nitride bearing
Isn't one of the issues here that the bottom of your vacuum chamber still bulges inwards when the vacuum level improves, like it did in earlier videos, which causes the surface to not be level.
moving mass of 4kg with 14k rpm. really dangerous. let me stick my hand close to it fast for experiencing the wind. please never change - but stay safe nevertheless ;)
n0peable forget liquid metal and hot nickel balls. that top has a terrifying amount of momentum at those kinds of speeds. I would not want to be anywhere near it.
@@garethjones4433 Um... Im afraid You're terribly mistaken. That thing spinning "so fast" is only going what? Lets say its 300 mph or lets just say its 1000mph (its not). The grenade, something like a m67 is going to explode at about 16,000mph. Its shrapnel is going at least 3400mph pretty close to the explosion and dropping off as it moves away (just as any peice coming off the spinning metal is going to) . Besides all that I honestly dont see any problem with their saftey barrier.
This is really awesome! I would love to see this done but instead of a top have it levitating on repelling magnets then in the vacuum chamber as well to remove even more resistance.
I just tried the Hydraulic Press App, and to be honest, I'm really not a mobile gamer... until I played your app. Now I'm a mobile gamer. Great APP and Awesome Video! Keep up the amazing work! 😄
You could make that piece the spinning thing is sitting on shaped like a bowl, so it will stay at the center. The bearing ball should be. as sharp as possible, somewhat like a needle, because this decreases friction, which I think needs the most energy in the vacuum. Mabe also put some oil at the metal where it spins on to further decrease friction.
actually it doesn't have to be sharp if its perfectly round. if you have a hard material(thats not plastic or aluminum like on cheap spinning tops) a perfect ball will be as good and even better than a needle. a needle tip in this case would make it unstable. ball bearing balls are very round. thats a lot better than a makeshift tip. balls are easier and more precise to make than needle shaped things.
simontay1984 It should be VERY little oil because if the base is curved the oil would all gather to the bottom and the top would be spinning in a pool... Not very good if you want as little friction.
The biggest problem with a sharp point is that it will cause friction. Why? Because at the speed this top is moving the point of contact will heat up. I am sure if they were to use a Temp gun on the tip they would be shocked at how hot it becomes. Now the total mass of the top pressing down on that single point no matter how hard will ultimately cause wear on the tip and damage to the base it sits upon. The incorporation of magnets in to the top plus a super cooled environment plus a vacuum chamber ( not sure how the vacuum would effect the liquid nitrogen. Possibly a split container where the cooling is out side the vacuum chamber). Anyway that is my two cents.
This is great experimental science. One variable to test could be using concave glass instead of steel as the base to reduce surface friction, as well as using a ceramic bearing ball instead of a steel one for the same reason. But I guess pretty much everyone else has the same idea :P
I used to do testing on engine cooling fans. We had a vacuum chamber made of 2 ply 2" thick cold rolled ballistic steel. It had an air powered air turbine that would spin to 130,000 rpm. We would test test the fans in vacuum until they failed. It would take 2 days to spool up until they failed. When the nylon/fiberglas reinforced fans failed you would hear "whoomp", then the motor would slow down quickly. When the lid was unbolted, all that would be left was a bunch of fluff. Pretty cool.
I appreciate your videos a lot, very enjoyable and good to watch. I'm poor so I can't donate or support your videos except by videos and advertisements, but I want to express my gratitude for the content you make. please keep following your intuition and using the skills you have. !
Air resistance isnt the thing holding it back. Its the friction from what its spinning on. Try a mirror, or something similar for the least resistance UwU
Love Your Video's!! Much more interesting than UA-camrs that think their lives are important enough to us all that we want to watch videos of their everyday lives!! LOL!! Great Stuff Love It!!!
When you make the new base what about making it plano-concave to let gravity help keep it centred? something like |\/| (you get the idea, obviously not as harsh an angle)
We ran a ~20mm brass spinning top on eyeglass lens for what I think was 45 minutes in athmosphere, started with pressurized air. The tip was a end of a really small tungsten carbide drill bit, something like 0.35mm
For the tip Id use a tungsten carbide scribing point or something similar. Regular tungsten is not that hard since its sintered and usually is only around 30 on the Rockwell C scale. It actually is more like a grade 8.8 bolt in terms of mechanical properties.
Just a thought, is the floor a level surface? And then all the other components flat and level too. Keep up the good work and stay safe, "that is all for today"
Another commentator made a good point. He thought, that the bottom of the pot flexes upward, when the vacuum is applied. That causes the base to slide off to the side, and tips it off level.
When the vacuum is applied to the chamber it will pull the walls inward in doing so it will also pull the flat floor up causing it to bow in the center making a decline around the edges towards the outside wall causing the base to tip toward the wall
I just sat down to with some flywheel energy calculations, and that thing was packing the same amount of energy as a .357 magnum round, or a small car traveling at 60 mph. That top is ridiculous.
Sorry, but yes it is. Kinetic Energy of a moving object it K=.5*m*(v^2), where m is mass and v is velocity. for a 3000 lb car travelling at 60mph, m=1362 kg, v=26.82, so K=.5*1362*26.82^2=489.851J * 1kJ/1000J= 489kJ, or the same as the top. Feel free to check the math yourself.
Well yes, but no handgun bullet has 489kJ kinectic energy. 8g bullet has to travel whopping 11km/s to have same amount of kinetic energy. Something like 40mm cannon can produce 400-500kJ numbers.
And that, boys and girls, is why you back-check your reference documents. I thought when I read it that a bullet packing 450 kJ seemed REALLY wrong, but textbooks are textbooks. Turns out they misprinted J as kJ on a chart.
on the steel base your using to spin the top on, try drilling a small hole and put a tiny neodymium magnet flush with the surface that should hold the top in the centre and stop it losing energy moving around, and also 3 in the base to stick it to the bottom of the chamber to stop it vibrating around, in a triangle shape on the bottom, to add twist friction to the base and hold it stiffer
Out of everything you have done up to 2019 This scared the shit out of me the most I have a refrigerated centrifuge I use for food And it spins about 2 gallons of liquids and it is made for it And it still freaks me out Bit this is why I love your channel
That is awesome! Can you imagine how much power was stored up? Reminds me of the show Supreme skills. It's a Japanese show where they make a top to see how long they can make it go.
PLEASE ! don't use tungsten tip ! your spinning top will mill the base in seconds ! the tip have to be smoother than the base ! when the tip mills the base it goes crazy...
Great video Lauri & Anni, thanks! The "Top" must be a bit out of balance and that is causing vibration? Maybe put some kind of putty or something under the base to keep it in place, balance the Top, and make the center depression a bit deeper?
This is a great demonstration of flywheel energy storage. But I can’t help but wonder what would happen if it were heated to glowing hot and dropped on the frozen lake
I use a concave mirror for spinning my top. The glass is hard, has low friction with the ball bearing tip, and the curved surface helps the top stay centered. But my top is 50 grams, not 4 kg.
Some things about the video:
-I tried first with base that was slightly (about 3mm) deeper on the middle but that made the top spin around the base since the side of the ball bearing that was on outer diameter had bit more traction and therefore generated force that drove the top around the base.
-The bottom of the vacuum chamber bulges inward but I think that didn't affect a lot since the top was all around the base in the vacuum chamber in stead of staying at the just one side.
-I think sharper bottom part of the top will help thing stay in one place with slightly curved base
Does the spinning top accelerate while creating the vaccum/pumping the air out?
Mig Ano no, because no energy is added. it will only decelerate slower becaus of missing air resistance
If the spinner hits a bump, flies off and hits you in the shin...shattering the bone........can you upload the video to liveleak please? (If UA-cam won't allow it)
Have you considered setting a Guinness world record?
To hold the base center inside the vacuum chamber you could consider making about 5 or 6 little blocks cut to fit between the base and the chamber walls and place them around the base like spokes on a wheel.

maybe when the vacuum gets under high pressure it pulls the bottom of the pot upward in the center allowing the base to wander toward one side(with vibration)
Yep. The base of the pot can flex just enough for the vibration of the top to move the base it's spinning on down the slope.

How about a ceramic (silicon nitride) ball bearing as the contact point and a slightly concave hardened base? :)

Now the total mass of the top pressing down on that single point no matter how hard will ultimately cause wear on the tip and damage to the base it sits upon. The incorporation of magnets in to the top plus a super cooled environment plus a vacuum chamber ( not sure how the vacuum would effect the liquid nitrogen. Possibly a split container where the cooling is out side the vacuum chamber). Anyway that is my two cents.
I really enjoy Beyond The Press. You're wife is so funny, such a goof! I enjoy the new content! Keep it up!
I love you guys. I down-vote all the copy-cat channels. You were not only first, but you do it way better than them.
PiousMinion Our Hydraulic Press Channel was first hydraulic press channel in UA-cam. :)
This is great experimental science. One variable to test could be using concave glass instead of steel as the base to reduce surface friction, as well as using a ceramic bearing ball instead of a steel one for the same reason. But I guess pretty much everyone else has the same idea :P
it needs a rubber pad under it so the base can't move.
I used to do testing on engine cooling fans. We had a vacuum chamber made of 2 ply 2" thick cold rolled ballistic steel. It had an air powered air turbine that would spin to 130,000 rpm. We would test test the fans in vacuum until they failed. It would take 2 days to spool up until they failed. When the nylon/fiberglas reinforced fans failed you would hear "whoomp", then the motor would slow down quickly. When the lid was unbolted, all that would be left was a bunch of fluff. Pretty cool.
2:24 - at the wood u can see "3310" - it is reference to undestroyable Nokia 3310? This wood is super solid, nothing can destroy it?
I appreciate your videos a lot, very enjoyable and good to watch. I'm poor so I can't donate or support your videos except by videos and advertisements, but I want to express my gratitude for the content you make. please keep following your intuition and using the skills you have. !
Air resistance isnt the thing holding it back. Its the friction from what its spinning on. Try a mirror, or something similar for the least resistance UwU
Love Your Video's!! Much more interesting than UA-camrs that think their lives are important enough to us all that we want to watch videos of their everyday lives!! LOL!! Great Stuff Love It!!!
When you make the new base what about making it plano-concave to let gravity help keep it centred? something like |\/| (you get the idea, obviously not as harsh an angle)
We ran a ~20mm brass spinning top on eyeglass lens for what I think was 45 minutes in athmosphere, started with pressurized air. The tip was a end of a really small tungsten carbide drill bit, something like 0.35mm
For the tip Id use a tungsten carbide scribing point or something similar. Regular tungsten is not that hard since its sintered and usually is only around 30 on the Rockwell C scale. It actually is more like a grade 8.8 bolt in terms of mechanical properties.
leggings!!! You're a legend.
Just a thought, is the floor a level surface? And then all the other components flat and level too. Keep up the good work and stay safe, "that is all for today"
Another commentator made a good point. He thought, that the bottom of the pot flexes upward, when the vacuum is applied. That causes the base to slide off to the side, and tips it off level.
these videos really scare me more than anything else you've done. Just imagining how much damage that thing could do if it went out of control.
I love the way you speak English. The rhythm and intonation is very musical and interesting.
Anni can wear leggings in every video
Please.
But, those shoes.
@@esra_erimez I never saw them lol
@@esra_erimez steel-toe?
With clogs
Very very interesting!!! I'm very exciting by waiting the next video about this!
what is that joint for the wood that allows it to fold like that? very handy
It's called a Hinge. You can find two on your nearest door.
@@JesusisJesus jesus wept
You can eliminate friction by levitating the top with a magnet on the base repelling against the steel mount.
HO LEE SJIT
It's Cowfoot that's where I laughed.
vakkuum champer : )
It's Cowfoot are you a cow furry
No... But I can see why you'd think that. :D
Crash ed
When the vacuum is applied to the chamber it will pull the walls inward in doing so it will also pull the flat floor up causing it to bow in the center making a decline around the edges towards the outside wall causing the base to tip toward the wall
Immediately when I saw the vacuum chamber setup that was my first thought before I watched any further in the video
I just sat down to with some flywheel energy calculations, and that thing was packing the same amount of energy as a .357 magnum round, or a small car traveling at 60 mph. That top is ridiculous.
Aleksander Flippen No not the same as a car traveling at 60mph😂
Sorry, but yes it is. Kinetic Energy of a moving object it K=.5*m*(v^2), where m is mass and v is velocity. for a 3000 lb car travelling at 60mph, m=1362 kg, v=26.82, so K=.5*1362*26.82^2=489.851J * 1kJ/1000J= 489kJ, or the same as the top. Feel free to check the math yourself.
Ashish Dutt rekt
Well yes, but no handgun bullet has 489kJ kinectic energy. 8g bullet has to travel whopping 11km/s to have same amount of kinetic energy. Something like 40mm cannon can produce 400-500kJ numbers.
And that, boys and girls, is why you back-check your reference documents. I thought when I read it that a bullet packing 450 kJ seemed REALLY wrong, but textbooks are textbooks. Turns out they misprinted J as kJ on a chart.
you could burn incense stick above the spinning top, see if it draws air down into vortex around spinning top... track the air flow
Was it just me who was waiting for it to fly off onto the phone ?
on the steel base your using to spin the top on, try drilling a small hole and put a tiny neodymium magnet flush with the surface that should hold the top in the centre and stop it losing energy moving around, and also 3 in the base to stick it to the bottom of the chamber to stop it vibrating around, in a triangle shape on the bottom, to add twist friction to the base and hold it stiffer
Latasin teidän pelin se on vaan nii paras samalla tavalla ku teidän kanavat💪👍
I really like watching your videos. peace from Fort Wayne, Indiana. USA
2:12 I have this safety... juttu here :D
Alepoju123
Out of everything you have done up to 2019
This scared the shit out of me the most
I have a refrigerated centrifuge I use for food And it spins about 2 gallons of liquids and it is made for it
And it still freaks me out
Bit this is why I love your channel
Is there a world record for worlds longest spinning top?
Over 24 hours
It's also possible that the inside portion bottom of the pot isn't exactly level. And when the top rocks around, the steel piece walks around the pot.
I want to see a top battle with those speeds. wow that awesome
Jeff Ward this has death written all over it lol
Jeff Ward closest you'll get is robot wars. there was a robot that had a huge spinning disc that Rekt everything.
That is awesome!
Can you imagine how much power was stored up?
Reminds me of the show Supreme skills. It's a Japanese show where they make a top to see how long they can make it go.
@ 1:06 Hahahahahahahahahaha
Freedom Forged i was looking for someone that saw it too👍
Hubby does not approve LOL
Anni's pants are hilarious!
Your spinning tops would be much more effective if most of the flywheel mass was distributed at the outermost perimeter.
I always love the strange experiments you guys come up with. You should make some more videos where you see how much weight everyday items can lift.
Man, be careful, don't create a dark hole
I love this channel. It feels like a miniature Discovery Channel show :D
PLEASE !
don't use tungsten tip !
your spinning top will mill the base in seconds !
the tip have to be smoother than the base !
when the tip mills the base it goes crazy...
I like Anni freaking out when the top started to grind the wall of the chamber. although I don't blame her. I'd freak out too a bit lol
I like her pants
Holds that fat ass perfectly
@@LPJMagicmusic well agreed!
Lol this kind of stuff reignites the childlike curiosity of the world within me. Pointless maybe but definitely awesome. Keep it up.
Annin kasvatus"aitaus" (aka safety juttu :D) kokee kovia :D
ilmeeni Se on itse asiassa eurolavan laita, niin mää en kasvata siä mitään. 😂
Ahaa :D joskus oon nähny tollasissa kasvatettavan jotain :D
Joo kyllä niitä siihenkin varmaan käytetään! Just kattelin et ainakin Biltema myy noita johonkin rehujenkasvatustouhuihin. 😀
Great video Lauri & Anni, thanks!
The "Top" must be a bit out of balance and that is causing vibration?
Maybe put some kind of putty or something under the base to keep it in place, balance the Top, and make the center depression a bit deeper?
put oil on the thing the spinning top spins on.
I meant just a really thin layer, but there is only one way to know - it has to be tried...
This is a great demonstration of flywheel energy storage. But I can’t help but wonder what would happen if it were heated to glowing hot and dropped on the frozen lake
gotta love the scandinavian accent :D
eeemeli1 But it's Finnish. Finland isn't part of Scandinavia.
Mark Rose I´m Fin and i didn´t know that. I blame the poor education :D My english is half that good
+eeemeli1 I"d put your worst english against the average American spelling any time and guaranteed you'd be more literate.
I could listen to your voice all day long!
the leggings game always on point, i make my wife buy more colourful leggings like her, it's slowly become my fetish now.
Cwings
Vat da fak?
I see Anni leggings i like the video
SCWfan06 actually, you reply to my comment is the sign you give a fvk to my shit.
SCWfan06 oh you edit your comments, ok, fair enough.
wat XD
I use a concave mirror for spinning my top. The glass is hard, has low friction with the ball bearing tip, and the curved surface helps the top stay centered. But my top is 50 grams, not 4 kg.
You should do a badass "fidget spinner" to show whos the boss
Amazing atheist you mean fid get speenerr
I think he calls it a "fitbit speena"
awesome concept! I think you might start something. I like the magnetic levitation idea along with the vacuum chamber.
f1 sound lol
senetaire lulu en vireé back in the day when they reved to 18 000 rpm
now they are turbo and only hit about 12 000 sound totally diffrent
BETTER than current F1 sound you mean !
when starting your bayblade sounds like an accelerating F1 car you know shit got real
