When I saw the thumbnail that said it spins forever I said "No it doesn't, mine stopped a while ago" Halfway through the video when he talks about friction I thought that's probably the problem as mine has a large air bubble on top. however, as soon as he mentioned how it uses the Earth's magnetic field. I looked and noticed I had a magnetic desk toy from the Vsauce Curiosity box sitting in front of it. As soon as I took that away It started moving again.
had the same thought, as mine has stopped. No magnets nearby, but the air bubble has grown since purchase.
Seriously, you put a magnet near such a sensible instrument, that runs on microcurrents, and didn´t think of any incoming-trouble while you did that ??????? Didn´t you know, for example, that your car´s modern spark-plugs are made so, that the mere vicinity to a cellphone cannot disturb their function anymore ??? (which was the case with older spark-plugs, till the first cellphone-owning-drivers started having engine-ignition-break-downs... )

Problem solving and engineering at its very best, in a product you can have on your desk. Electromagnets, photoelectric effect, thin-film lubrication, neutral buoyancy. All combined, you get what looks like pure magic.
Now if they can only solve the air bubble problem (see above comments).

@@somecsguy9824 The air bubbles appear by magic, then?
@@catkeys6911 They get removed by magic.. into the phantom zone
I understand the photoelectric effect to be high energy light bombarding -- and ionizing electrons in sparks off of -- materials (including recently rubbed metal surfaces, e.g.). Is there something I'm missing? Maybe you mean photovoltaics?
What nostalgia. In 1983 I made a similar mag-torque perpetual motion machine back at Lawrence Tech. The circuit board was open to view, no batteries, no solar cells. The board balanced on a needle point, long arms extended the coils and lowered the center of gravity to below the point of support to balance it.
Took a while before someone figured out that those long arms were a dipole antenna and it was running on power it picked up from WXYZ, a large radio station with a transmitter and antenna tower across the street from the university.
ha ha, would love to see that!
@@TheActionLab That would be interesting to diy !! It could be an interesting idea for you to make it. Would love to see the video !!
@@HemantKumar-xn8mnget out of here flat not moving earther
@@joewashington9374Flat earthers couldn’t annihilate anyone in a debate. I assume you are joking but still, you do sound very silly.
@@joewashington9374f you are not joking, you really should consider reevaluating your life choices rather than being a fool on the internet. If this is in fact the case I would love to see an explanation of the seasons, or how the Earth somehow remains unaffected by any sort of gravitational effect of other planets. How can it be that for one part of the yeah it is summer in the south and winter in the north(of the world, above the equator). Or if it doesn’t move at all(no spin) how it can be nighttime on one side of the planet and not the other. But the main question, if the Earth is flat, where is the edge? If I sailed far enough could I fall off? Where is the cut off? Please do remember your size relative to the Earth, and don’t try to use that as an argument I don’t want to see any “Why don’t we feel the Earth moving” or “why can’t I see the curvature” as you are obviously a tiny spec relative to the size of the planet and are also spinning/moving along with the planet so feel no motion relative to the Earth.
To be honest, I thought this entire video was going to be about the actual Earth, constantly spinning as it went through space.
If anyone is wondering what they cost:
4.5" - $198
6" - $298
8.5" - $500
@Kelly Harbeson I just looked at their website and that's what the prices were listed as.
Bit on the expensive side, an missed opportunity to offer a premium flat earth variant 🤣
Was about to look but this comment section is full of people complaining about air bubbles around the 2yr mark, that's a lot of money to waste on a 2yr item
Feb 2024 prices are the same but most are out of stock
I have window seal dollar store seasonal decorations that move with solar panels and cost a few dollars, this thing is a very over priced concept imo
I have one of these and I wasn't aware of the "two fluids" trick. Well done.
Yeah, he answered every question I had about it.
Where did you get your globe?
I've had my 6" globe for about 5 years with no issues. These are definitely not cheap objects, but they're a very unique decoration with a high build quality. People are always very intrigued by it whenever they come over. I think they are worth it and even bought one as a gift for my brother.
I can't remember what they are called but the solar cells used in tiny small current devices like calculators have a quirk where they are super efficient at low light low power settings but basically have a hard limit where more light doesn't increase the output voltage much at all. I forget the details but I think their internal resistance basically increases with more light. At a guess I'd think it would be something like that limiting the power.
I didn't know that. It could be really useful for my plans! :3
I had seen these around and I couldn't really comprehend how they worked, you're amazing at explaining things!
Yea I thought these were just scam adverts but at least now I know they're actually real. It's easy to be cynical with the amount of scams about these days though.
Love this guy!
but the globes are expensive :(
Solar. What explanation is needed?
I had one from over a decade ago and they do stop. It was fun to dissect for magnets, but the oil is something else!
The problem with the Mova globes is they tend to get a bubble of air in them, and the spinning stops. Mine happened after about two years. You can research this issue, and some people came up with a solution to add more fluid and got theirs working again. It needs a small hole drilled in the top, add fluid with a syringe, and then somehow glue the hole closed. But pretty expensive for an item that may only last a couple years.
It happened to mine too
"Forever" or 2 years, whichever comes first. At that price, the warranty should be for 5 years. They do offer a 40% paid replacement discount.
@@gubigm I'm going to attempt to fix mine. I feel sure it will do it again, but maybe I can get it working for a couple more years. I wish I knew how many globes get this problem. Is it a low percentage, or every single one of them eventually does this? Does the fluid somehow slowly seep out thru the plastic? My bubble is pretty large now. It's about the top half an inch in the 4.5" globe.
Thanks for the heads-up. Was considering purchasing one.
Serious question.... how do the bubbles form...? I'm gonna guess that it's residual air pockets in the components not being thoroughly vacuumed out during the filling and sealing process....so the tiny micro bubbles jus get bigger an bigger till.....BAM, ya end up with a big ass air pocket in 2yrs...?
Wow! I always wondered how it works and the explanation is so simple and yet so brilliant! Thanks for sharing this clever design!
I love how you've started breaking down and dissecting these new/popular trends and toys.
It always looks odd to me when you see a really thick liquid that's less dense than another liquid that's much less viscous, even though I know there isn't necessarily a link.
It actually makes a lot of sense. Think about water and olive oil. Water is more dense than oil, that's because water molecules are much smaller than triglycerides, so you can pack more of them in the same space (Type of intermolecular bond also plays a role). Olive oil is more viscous than water, that's because the longer molecules of the fatty acids entangle with each other forcing you to apply greater force in order to move them.
Hope that helps :)
@@denzelcrocker992 Actually I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux,” and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.
Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.
@@denzelcrocker992 Your comment helped me understand. Thank you.
@@user-kk5qe9fj2l where did Linux/GNU come from? was his comment about operating systems before he editted it?

The Action Lab's USP isn't expensive equipment, or dangerous chemicals, or anything fancy. But it's something insanely important on RUclips, and it's his ability to generate ideas and seek inspiration from the things around him. Video after video this channel blows my mind with these explanations of things I've never paid a single thought to.
Ok buddy. 👍

i had to rewind it a few times to understand it. 😂 amazing work! I smarter every time i watch these!
Amazing! Thanks for doing these episodes. 👍
I once put a small neodymium magnet that had a low friction side on an office table. It would align itself with earth's magnetic north with enough force that you could feel it by pushing your finger against one end. It was amazing to feel the magnetic field of the earth when that little magnet pushed back.
The magnet might have been aligning itself with steel screws and/or beams under the desktop. To be sure you have to look carefully underneath to make sure you are using the desktop far from the steel framework underneath.
@@qazmatronyou just ruined this man’s whole life😂😂
This globe has been puzzling me since the day I first saw it, what an absolute brilliant application of simple science!! I knew there was some kind of magnet involved but this demonstration was "enlightening" 😁
I love it when someone finds a way to create something that taps into natural energy source that exists all around us, in a very efficient way. Obviously it cant put out more energy than comes in, but finding efficient ways to interact with our surroundings is so cool. Like that light bulb 💡 with the black & reflective spinning thing inside the bulb. Or, the bird that continues to dip into water due to it containing a liquid with a low boiling point heat transfer loop. Stuff like that is just really facinating to me because it takes creative ways to interact with natural forces that exist around us.
That's what oil already does. It's stored sunlight
That's a cool way to put it
There's a really cool clock called the Atmos which is entirely powered by tiny temperature differences in the room and it runs non stop without being wound up
Totally agree! It's super cool.
The bulb with the black and reflective spinning thing is called a Crookes radiometer. 🙂
This is incredible, thanks for explaining so well!
Thanks for explaining the basic working. I was intrigued about it.
we have a bunch of these around my office at work. They stop working after a while, usually the air bubble at the top increases.
maybe shaking it up from time to time will prevent the buildup of one big bubble and keep the bubbles smaller. it probably has lots of microscopic bubbles then they accumulate over time. not sure buts it’s my guess lol
3:48 I thought he was squaring up to punch the globe
I had seen these globes in YT shorts and thought it must have been engineered very well,thanks for explaining ❣️
We humans have such a potential for solving problems and creating life enhancing devices but we are so limited by ignorance in many areas. We so need family love and the best of education, and never lose sight of that. Another amazing video.
Only 1% humans have that ability. I never found intelligent people outside my uni and science forums
Probably already stated, but your LED light source does not provide a meaningful level of photons in the light spectrum to power the PV cells in the globe. Cheap PV cells are fed mostly from NIR wavelengths.
Cheap PVs are mostly CdTe solar cells which works really fine on room light. Infact modern room lights (mostly LEDs) don't radiate NIR at all, it's spectrum spans mainly from blue to red which has way higher energy than that of NIR. His high power light source is no different from any room lights except it's incrediblly powerfull.
Absolutely love that Earth and Moon globe that you have... I've been wanting that set for a long time!
I don't think they're at the same scale. Distance is also too small .

High precision and tight tolerances are expensive. I would imagine the amount of mass is quite a small amount, probably on a similar scale to a radiometer.
Just went to the website. I now understand your comment.😲😃
@@jaye1967 tight tolerances?
And according to a few posters here they tend to go haywire after a couple years.

I bought one of these 6 years ago and it is really cool, it sits on a shelf in my dining room and always spins when the sun comes up❤
It looks really cool. It would be incredible having one that has a 24 hour cicle
@Kelly Harbeson yeah, I know, but it would look nice as a background, where after a few hours you would see a different part of the globe. The only problem would be that there would be some parts that you would never see because it would be night (although in those cases I don't know if the globe could still rotate without access to light)

I prefer the cube version of the MOVA. I saw one at a travel agency years ago & looked it up. I didn't want to spend that much then but I did buy one recently. It is very cool watching it float & spin in the middle of the cube's fluid. I do not see a fluid line change in mine. Also the MOVA logo at the top of my cube seems magnetic. I tested it with one of those magnetic field sheets. I assumed this was part of the spinning engineering.

@@youravghuman5231it would be cloudy, but it wouldn't say. There's no reason to believe it would sink. We couldn't find a fluid for the bottom portion that's the denser than the milk and the top portion that's similar density. And in fact, for the milk we could probably add a little bit of something to bind it to stay as a kind of cloud. Or even find some extremely light effectively solid flat things to float in there as clouds.
I wonder how they sealed it

Would it be possible to build a buoyancy bearing that would never wear out using this technology?
A buoyancy nearing would not be practical. It needs too much heavy liquid; heavy liquids can be dangerous (mercury, lead salts in solution); the viscous drag could easily exceed the friction of a roller bearing. A magnetic bearing is a better start.
*The hardest part about making a perpetual motion machine is where to hide the battery.*

I saw these globes for the first time last month (Sept 2023) while on a cruise ship in the Mediterranean. I couldn't figure out how they worked. After seeing your video I'm more amazed at this globes as they spin in a cruise ship hallway that wasn't partially well lit.
3:02 : technically, this sentence is wrong: you can spin the motor without any anchorage: in this case, both the stator and the rotor will spin, but at opposite wises and with each speed inversely proportional to each mass.
So here, with an heavy mass on the shaft, the globe will spin even without any Hearth magnetic field.
ok, if it weren't for the tail rotor, the body of a helicopter would rotate in the opposite direction to how its propeller does.

This is awesome 😊
Adorable 😍. Is there a miniature version? Like a tennis ball or something.
I thought of the 2 liquids of different densities immediately, but driving it against what is essentially a compass needle, now that is clever!
That will also be what governs the speed, more light making more electrical current will meet more resistance due to friction. Clever really.
@@alasdair4161 Well, drag in fluid flow is governed by: D = 1/2 . p . V^2 . S . Cd . This means that speed is proportional to the square root of torque. Increasing torque will deflect the compass more away from pole alignment, increasing it's reaction torque against the motor torque. So, the there will be a speed increase with more electrical power, but the above formulae means that the velocity increase will be proportional to the square root of the torque (other things being equal), making the increased speed less noticeable than it would be if it were directly proportional. Also, the design of the electric motor, most noticeably it's timing angle will come into play above some RPM & also limit speed increases by nobbling torque.
