Nice video. It's really great to see the boulder able to find the time away from chasing Indiana Jones.
LOL! I can't believed that never crossed my mind before! Now I can never un-see it! Thanks so much. Paul
You win. Lol
This is awesome, it’s a fountain, sculpture and scientific demonstration all in one.
That's a great way to express it.
This is pretty damn interesting, I've never seen one of these before I wouldn't of thought it to be possible.
Glad you enjoyed this. I had seem many small ones over the years, but the one in Baltimore and then THIS one were my first encounters with truly large ones.
They’re popular in Germany…smaller versions of course.
No need for differential equations or calculus to understand it, if the sphere is 60000lbs and the base is something like 6 feet in diameter, so a bearing area of ~4000 square inches, meaning water pressure of as little as 15psi (utility water is 40-60psi) could suspend the sphere.
That seems reasonable.
@@Realunitedstates hmm, I'm trying to explain:
case 1: 4:00 Aqua-Planning -> the tire has not enough time (impuls=weight/s) to sink'ng
case 2: this Kugle in Aquarium -> simple sink
That’s incredible. I love spheres, & I’ve seen headstones that are stationary, but nothing like this🥰❗️
I have also seen the spherical head-stones, but never really thought much about it. So glad you enjoyed this video.
I'm glad I found my way to this video. Thank you for posting. I've only seen one Kugel Ball. It was in the small resort city of St. Vincent in northern Italy. It was over 20 years ago, but the experience was unforgettable. I hope to go back next year. Truly mesmerizing.
Glad you enjoyed it! Besides this one in Richmond ,VA, there is one at Inner Harbor in Baltimore, MD. Not as large, but still impressive.
I was gonna make a Kegel joke when you said Kugel but I stayed to watch the whole video instead . Really cool video! Makes me want to visit the science museum here in manhattan soon
Thank you, I'm glad you enjoyed the video. I would very much like to visit the science museum in Manhattan some day. That sounds like a great outing!
Hey, which museum? I’m a New Yorker I’m wondering which museum you referring to? AMNH?
WOW. "pleasing to my eye" ,an teacher once taught me. I love stone balls!
Well I'm glad you enjoyed this.
We have a ~3 foot diameter one in my town and i love it
This one is on another scale, awesome
This is an interesting kugel ball, which is new to me and your 2 & 1/2 hour drive, I believe really worth it:))))
+Firdaus Idros Thank you. I am so glad you enjoyed this video! It really is a fascinating thing to experience. Some problems ensued on the trip, and we ended up spending about ten hours on the road total, and with post-production this short video entailed about 12 hours, but I also feel it was well worth all of it. Paul
This thing's really neat, cool video. Time for them to step up and make a scale representation of Jupiter now, lol.
Thanks so much. Yeah, I get what you're saying. I really wonder how they managed to cut and polish this piece of stone. Thanks again! Paul
And one of YT Scuti.
I never heard of a kugel ball before. This is very interesting.
They are quite interesting. I've seen a few over the years, stretching from as small as a baseball all the way to this giant. Thanks!
My bubbe mashes up leftover potato kugel and rolls it into balls then she fries it
just FYI, kugel is the german word for sphere or ball.
All I can say is WOW!
+A W 2 Wow indeed. When I grabbed onto it, I got a real sense of how heavy this sphere is!! It is enormously fun to play with! Both Bev and I had a lot of fun turning it. Thanks! Paul
Wow! the big one. Didn't expect it to be that big from the thumbnail. It's very interesting. I've seen a few smaller one here(my country). Thank you for sharing.
+munarong Thank you Narong! It is difficult to show how big this is in the thumbnail. I am really glad you enjoyed this one! It is good to hear from you. Paul
"Kugel ball" is an incredibly redundant term.
"Thank you for calling, Department of Redundancy Department, thank you for calling!"
Flat earthers when they realize, that it's literally a spinning ball with water sticking to it: 😱 😨 🤯 😲 😯 😮 😳
LOL!
Just got ours up and running in Columbia sc. Been waiting and waiting for forever. Literally just had a ball messing around with it. Thanks for the informative video! Hope you doing well sir.
Thank you. I am doing well, Glad to hear you had a good time getting the one there up and running. Paul
Thanks for showing us this, Paul. Really cool. Hey Bev, be careful you push that thing out of its socket and damage someone:)
+chiefamylee Thanks Amy Lee! It is rare to find the biggest, smallest, oldest, first, of anything, so when we do it is always a special day. Paul
Thanks
Welcome
I'd love to see exactly how the balls are made to be so perfectly round which I think is the real miracle.
Wow very nice idea
tHANKS, GLAD YOU ENJOYED IT.
These could also be done on air bearings, but the fit would have to be very precise, probably no more than five microns of tolerance if you want the pressure to be reasonable.
We have one in Village Point shopping area in Omaha. It's pretty awesome! Amazing how it can be turned by hand. It's decent sized and takes some doing, but worth the effort!
We've also got one in our zoo
Awesome. Thanks for sharing.
Thank you! I am so glad you enjoyed it. Paul
It works the same way the bearings in an engine work.
What a nice way of explanation.. even for a non English tongue..
Glad you liked it
Wow very nice 👍
Thank you so much!
That is very neat.
I found it pretty fascinating. Thanks.
This is in Richmond 😱 I gotta go see it
Lived here my whole life and didn’t know this existed lol i saw one at a zoo in Omaha Nebraska
Yeah, it is ( or at least was) right out front.
awesome. the only addition i can think of is if you were to use a dramatic, surrealistic, theatrical, mysterious inflextions for your voice, because, with the effort of speaking to the distant camera and above the noise, you may as well be making that presentation as theatrical as you can, especially changes of rythm and pitch for the strange things such as the weight and the mystery of aquaplaning. thanks for the video.
Wow cool! This reminds me of the one at disneyland!
Cool! I don't know if Disneyland had theirs when I was last there, but then that was about 1966. :-) Thanks!
RealUnitedStatesVlog dang! And your welcome
5:44 Bev, the strongest woman in the world ;-)
worlds heaviest rollerball mouse
Kind of an odd association, but okay.
When art meets science and engineering.
That is absolutely correct. It's really quite pretty and impressive in person. Thanks!
The big ball keeps turning
Well, yes, as long someone's there to push.
I'd like to know how they make the ball perfectly spherical.
I agree. I would imagine that seeing the manufacturing/cutting/polishing process would be really interesting. Thanks.
Look up the world's roundest object, I think you'd like that.
I'd rather see how people with only copper hand tools did this 3500 years ago
Whey can make it look like universe if they put some colours on this ball
Perhaps.
i live 6 blocks from this place...cool
+Scootersniper Davis Wow! Small world! Well you live in a fascinating city, full of a rich history and lots of very cool attractions. We hope to visit again to video more of it. Thanks for watching and commenting!! Paul
RealUnitedStatesVlog thanks...
I just like the way he says “shtick”
LOL! I am told I have some eccentricities to my manner of speaking. Glad you enjoyed it.
Love you 😘
That's sweet.
They did it with water! We still float a granite kugel ball @29 tons in front of science museum of Virginia in Richmond…
Thanks
How are these balls made? How they make them perfectly spherical? I really wanted to know.
I believe there are specialized turning and then finishing/polishing machines, but I do not know specifically how they work or where they are made. I suspect a quick internet search will tell you more.
Hi, I went to Cancun, Mexico for vacation and there was one about this size in the amusement park "Xsense"
cool
really cool
Thanks! I certainly found it fascinating. So glad you enjoyed this one!! Paul
that still amazing. how do you even move a broken one? and where would you put it?!
+Jo-el Benn Well, answer to the first question is with a crane. Answer to the second, is they moved it to the back of the museum and put it on display. We attempted to go film the old one to put in this episode, but it was inside the fenced grounds behind the museum, which would have involved paying to enter the museum, which under other circumstances would have been fine, but we were out of time and daylight.
this is how the pyramids were built . floating stones into place
I agree.
That's 8,000 lbs heavier than one of the blast doors at the Cheyenne Mt complex
I'll take your word for that.
очень круто !
Спасибо!
I'm amazed.
It is very cool to see in person, and since it is outside there is no charge to see it.
Wonder what the PSI pressure of the water would be.
only 21 psi they say
could it be made of marble
All of the sudden you look thinner Paul, have you ever considered to wear one of those kugels? Just kidding that was an amazing video, thank you for sharing
+Superman21986 I suppose by comparison I look smaller. LOL!
Yea, that thing is huge. I wonder how much the kugel ball in my city weighs. Anyway, it's not even close to that!
+humpsuka Well, if you get really curious, the math is relatively simple. Volume of a sphere is 4/3 pi r^3, and the density of granite is 2.75 g/cm^3. :-) But yes, this one is indeed huge! It is my understanding it is the largest of its kind in the world. Thanks! Paul
Would it be possible to make one with a 63.7 meter diameter with a map of earth on it, making the average highway close to the with of a hair, at 50 micrometers?
Or even better, 127.4 meters?
It'd be massive as all hell, but maybe if it basically sat embedded in a very large hole in very solid ground, it could work? It would be an awe-inspiring sight. You'd be able to see your home.
Well, mathematically, it might be possible. There are four significant obstacles that spring immediately to mind: finding a single piece of granite large enough and flawless enough to be turned into a sphere, moving said monolith, finding or building a lathe capable of the task, and perhaps most significantly of all, financing such a massive undertaking.
@@Realunitedstates How about instead of granite, an internal steel structure covered by plastic sheets with the printed map on them, again covered by a protective coating/epoxy layer, which could then be polished?
Somewhat similar to Maine's Eartha 12.7m globe, but with more curved and rounded panels to enable the rolling motion.
It looks hard to accelerate those past a certain point; what's like the surface inertia of such a large ball? I wish I could be sure that made sense as a question; I can explain, but will just confuse what I mean.
Well I THINK I understand what you are asking me, but unfortunately I have no means of measuring the inertia or the surface frictional load. Obviously I was able to rotate it with my hands, but it is massively resistant to acceleration or deceleration.
@@Realunitedstates well not really the friction; for a say 1 inch shell around the ball, that has a certain mass, at a certain rate, that has a outward force (well linear force and sin(rotation speed) or something) ; And it seems; and I haven't had one to play with; it seems very hard to get to spin very fast? Maybe it's just a appreciation that it might be sort of delicate that stops people from trying?
Can that small granite ball be pushed from that ball holder?
Short answer: no.
I'm looking for info on the small one like this in Disney World in front of the Merchants of Venice.
I have no info for you. I don't recall the one you are referring to, but then it has been quite a while since we were there.
I had never seen that ball in my town.
I'm sure the ball would "sink" into the base if the water was turned off but how would it get raised again? That would be an awful lot of hydraulic pressure, initially. Just thinking out loud and no, I don't plan on turning off the water to the ball... ;-)
I am not entirely certain how the physics work to be perfectly honest with you. I have looked at the mathematical explanation, but I never took the time to actually try and work through it all. So I really don't know what the "start up" would entail. But I suspect it is not as big a deal as it might seem, since hydraulic power is, obviously, deceptively powerful. Thanks! Paul
yep as long as the pump can deliver the pressure needed to lift the ball it will be fine. fluid under pressure is very powerful. just look at the braking systems on cars. very small bore pipes pushing large pistons and creating huge forces to stop vehicles weighing 2 tons or so.
What size pump is required to generate the water pressure required to float the 1000 lb ball? What is the size of the hole beneath the ball through which the water comes through from the pump?
Can I please get a video of you trying to stop the ball with your bare hands? I know it can be done...
No.
@@Realunitedstates Youre useless
Oh look a ball ball 🤔
The distance between Earth and moon is to scale
As I recall, yes.
Paul, thank you for this detailed presentation! I have been curious about the pressure required to lift 29 tons - do you know the horse-power of the pump or the water pressure that is required to lift the ball? Will this system work on flat surfaces? I believe that I saw flat marble being moved this way... Again - thank you.
Unfortunately I don't know the answer to your questions. I have seen some elaborate mathematical papers online that explain how to calculate some of the requirements, but I don't recall where I saw them, I just know they are out there.
RealUnitedStatesVlog Thanks for responding. I’ll keep looking - if you come across something regarding flat surfaces please let me know... mark@melni.org
The pressure of the pump is an incredibly low 14 psi to 21 psi (pounds per square inch). And these are very weighty objects. We can make them from 1 foot in diameter, weighing 84 pounds, to nearly 10 feet in diameter, weighing 40 tons! Yet even a child can change the course of a floating ball and set it on an accelerated twirl, only to return to its normal rotation when left alone. Source: Kugel.com
so wait could you keep adding force to it in one direction and get it spinning really really fast
No. There is still a frictional element to overcome.
Yes if you added more water force from below then add a jet pointing at the ball.
What if you put your fingers in between the ball and the fountain then someone turns the water off
Were any of that possible the result is axiomatic. However, it isn't possible since the gap between the two stone surfaces is incredibly small, making it physically impossible to get anything positioned in there.
I still don’t get it! But thank you anyway!
Me neither
Whats the water pressure.?
I don't know exactly, however, given the rather demure cascade of water coming out from under the ball, it isn't very much.
Does the water not cause erosion over time?
My initial response is: not perceptibly. The water is clean, so does not carry particulates that would act as an abrasive.
How do they did it? Is their a site?
Well, the museum has a site, but I don't recall them having a page specifically on the physics of the kugel ball. There are some detailed papers in PDF format online explaining the physics and math of how it is accomplished, but again, I don't recall a specific page. But I do recall the math is not pretty.
Now they just need one for the sun
It would be fun to do the calculations of how far away and how large it would have to be. I suspect both would be approximately equivalent to Mt. Rushmore. LOL!
This type of technology was used for drilling high feed rate / torque low rpm bores in ancient egypt construction
This is like an FU to all flat earth believers since they believe water cannot stick to a round spinning “sphere”.
I never really thought of it that way. Flat earth is not something that I think about, largely because the concept died off about five centuries before I was born.
RealUnitedStatesVlog So did I until I met a “flat earther” in person. To my horror, I found out it’s a “movement” across the US, EU and Australia counting in the millions. It mainly consist of gullible, lonely people and charlatans who seek to profit off the naive ignorant individuals. Perfect example of the downside of free speech.
these look dangerous
IT is sort of a weird thing to see in person, but they really are pretty safe. Thanks!
@@Realunitedstates ...until you stick you finger in the water and the ball stops :)
what happens when you spin it too fast
Well, "too fast" is an ambiguous term, but that said, while there probably is some theoretical mathematical upper limit to a functional spin speed, there is no practicable way to achieve it, so, you aren't going to over-spin the ball.
@@Realunitedstates sorry to ask a vague question,i was meaning to ask if will it somehow spin out of control or something, but you answered it, thank you.
Ah, okay. Glad I was able to answer your question. There have been any variety of questions about various safety ideas since posting this, but despite the seeming cool effect of it floating on water, or more accurately a sheet of water, there really is no way for this massive piece of stone to pose any concern. It just sort of sits and spins in its little pocket of stone. Thanks!
How fast can I spin it 🤔😂
Not very. There still is the mass and inertia, and a frictional load all involved. But it's still fun.
Maybe the great pyramid was built using a similar principle.
I suppose hydraulics play a part somewhere along the process.
8ft 8inches in diameter? so are you like 7ft tall ? standing next to it , it doesn't look 8ft across
LOL! No, I'm actually 6 feet tall, but I am also standing in the foreground just a little, so the perspective may be difficult.
59000 or 29000 pounds? Please decide yourself for one version.... :-)
One was pounds one kilograms.
Did anyone notice the glare of the sun when the ball was wet and dry? The water made it triple in size...food for thought.
It is just reflectivity.
there cup holders in Egypt ball are all over the world base are in Egypt think world wide war
Kugel means ball. Saying Kugel ball is funny
Well, perhaps the pleonasm seems unnecessary, but then if I didn't use it, someone, would complain that I was calling this a casserole, since kugel has multiple uses or meanings.
ball banana ka tareka ki video dikhaye
Can anyone tell me what its use for ?
It is an artwork, strictly ornamental, it has no utilitarian purpose.
@@Realunitedstates got it thanks for reply
"Can anyone tell me what its use for ?"
It shows to flat earthers that water can stick to a ball. :)
omg i live in richmond,va i got something to said i am the only real psychic and medium plus gift witch and voodoo priest next time u come to richmond,va u should interview me be the only real psychic,medium, male witch,voodoo priest
Jovon, thank you for volunteering to be interviewed. I will certainly consider it. I'm personally battling cancer right now, so it may be quite a while, but I will contemplate the idea and maybe when I am better we could do that. Thanks again.
dont bother - if this was a real psychic they would have told you when you were coming to visit
I heard a midget medium escaped from jail out there? Now there is a small medium at large lmao!!
too bad the Earth isn't a sphere.
Well perhaps, although nothing's perfect. :-)
I wasn't implying the Earth isn't a sphere because it's "not perfectly round" The Earth is not an oblate spheroid either, it is a stationary level plane, not a spinning ball "planet". It's a good video though, I just wish you hadn't said it was supposed to represent the Earth, even if that is what the artist claimed, because it isn't true. Still a cool thing to see, even if it isn't an accurate representation of our home. :)
dan silberstein too bad you have no scientific proof for your claim which makes it pure conjecture. You can't debunk the accepted model unless you have a working model that better predicts our observations.
I have a small fountain that was bought in an Asian store with a rotating ball as well. Unfortunately the ball wont rotate right, sometimes it would just stop...Do you know how to fix it?
Bill Hahn I first saw a granite sphere in a half spherical cavity in Germany in 1999 while on vacation. It rotated only when pushed. It was red granite and I thought it beautiful and unique.
I’m starting to get a tingly feeling how the pyramids had the stones transported….
Perhaps
I did see a documentary where they recreated the construction of the pyramids. They found that they needed fewer people to drag a stone on a sled if the sand was watered. The wet sand acted like ball bearings and reduced the effort to move the load so much so that when the sled hit the wet sand it shot forward in an uncontrolled way endangering those pulling it.
Kugel Ball sounds so weird in German. 😅
Yeah, I get that. Not entirely certain why these are referred to that way, but I can understand that ball-ball sounds a little weird.
The question I have is how much PSI is under the ball? and the small one (I presume less).
While I don't know the exact amount, it seems that is really isn't very much, as witnessed by the relatively gentle flow of water from around the sphere where it meets the base. Were the pressure high, the water would escape much more violently.
