Really clever idea! You might try painting the copper black and playing with the shutter speed of the camera to get a stroboscope effect that will make the copper look like it's not rotating so fast. Alternately do a really slow shutter speed so the cage is a blur and the sphere stands out better since it moves slowly
Hey, love your videos! I was curious as to whether or not you have considered making content about the potential uses of thermoelectrics in personal temperature control? Like a air-conditioning suit using that thermal fabric of yours alongside a thermoelectric cooling pad.
Or put an optical sensor on the drive, place a slotted disk on the shaft, and use a LED lamp, so that the lamp only shines when there is a view into the sphere from the camera. Will need to be optical simply because magnetic will not work with that massive field. Copper sphere would be best also heavily plated with silver, to reduce skin resistance, or of course if it was cast entirely in silver as well, either pure, or alloyed with copper like coins, so you get a harder alloy, but still with lower resistance.
You beat me to suggesting painting the magnet! It's fine, I'm already subscribed to you. I was going to suggest a bright blue paint to contrast with the red copper.
The fact that the metal casting process you have is so precise that the pieces come out with obvious layer lines it inherited from the original 3D printed pieces is absolutely incredible!
7:55 YOU NEED TO CHANGE AXIS OF ROTATION - that slice is disrupting the eddy current / Lenz’s Law, and the orientation is exacerbating the issue. You're rotating the sphere around the poles, and the slice is along the equator. If you move the axis of rotation to the equator, it will allow for larger, more continuous eddy current loops to form. There’s a short titled “Can a non-magnetic material be stopped by a magnet?” by tamuphysastr that overviews this concept pretty well
Or have a different design for the copper sphere that allows the eddy currents to form. The structure of the sphere, with all those holes, is limiting the size of the eddy currents. Try a sphere with bands perpendicular to the axis of rotation. I'd also try it with the cylindrical magnet inside the sphere.
No rotating over the poles. The magnet will always turn to align its poles with the axis of rotation, i.e. so that it feels the lowest forces. For the same reason it starts rotating with the sphere until the speeds match, the eddy currents cease, and it stops levitating :(
It's 100% the shape. It's creating patterns in the eddy currents which want to follow the shape of the copper. Remaking the mold with a band like structure (Think a spherical set of jail bars that meet at the poles) might give a better result. Or, if you wanted to have the bars of copper going along the axis of rotation, clip them in a cage like formation with plastic bars running one way and bands of copper running the other.
I love your workshop. Your way and quality of video recording. How you work. How you talk. The patience you have. If it weren't for one... or rather two small, unimportant details, I could fall in love with someone so intelligent and a lover of science. And who also has money!
The "sphere" has 60º rotational symmetry, so you can multiply that stroboscope by 6 (n/10 fps): 60RPM = 6fps 120RPM = 12fps 300RPM = 30fps And use a short exposure time (with lots of light) so as not to blur the sphere to help it look stationary.
A stroboscopic light at 1/10 the RPM would give a better effect than changing the exposure, it would also be easier to synchronize with the holes of the copper sphere
@@robspiess I thought that if he matches the RPMs to the FPS it should be enough, because each frame would equal one rotation and would capture the truncated icosahedron on the same position every time, making it look stationary, so we should be able to see through one of the openings as if the truncated icosahedron was stationary.
I mean that's a surefire way to get it to look stationary,but given there is a symmetry in the icosahedron, there are multiple sweet fps spots to get that effect. @@LeonardoG1981
Huge thank you, for making this video! My 50cents: Quench the copper to increase the electromagnetic conductivity, yes this will influence the total size and possibly shape of the sphere, I would suggest doing this in multiple 'soft' stages, where you raise the copper's temperature and then rapidly cool it across several slowly increasing increments to maintain structural symetry as much as possible. There seems to be a definite need to play with lighting and the coloring of the sphere to better showcase the events, I think it would definitely make it look more awesome. I'd love to see you use this sphere in a future video where you showcase some interactions with its unique shape and ferrofluid.
Your pre-visualization, planning, industriousness, and execution are astounding and beyond admirable. Please start a Bill Nye/Beakman-esque show so you can share what you’ve got. My son and I would LOVE it. Keep it up Captain. 👍🏽👍🏽👍🏽
Cast a thinner/Sand down the inner circumference of the chew toy? Make larger holes in the sphere? Weaker magnet? My thinking is the Hall Effect is overwhelming the power of the magnet because of the volume of copper. Even at slow speeds, there's too much resistence being generated by the sheer volume of copper in relation to the volume/effect of the magnet. In other words, Too much flour, not enough eggs in the cake. Try a larger area around the magnet, a smaller magnet, or less total copper around the magnet via larger holes. One/all of them are your solution. Find a ferrous sphere magnet and see what happens! I bet you could do higher speeds purely because of the MUCH weaker interaction between the materials.
I love that you keep all the "repetitive" dialogue in the video. Makes brain feel good. The ceremic slurry, FUSED sillica sand, vitrify the shells, melt out the plastic etc. etc. My personal favorite are the Petrobond videos where you compact the sand and cut out a path for the metal to flow into
The video has a slightly hypnotic, ASMR quality to it. Now make into a long loop where at the end you set down two copper icosahedrons right next to two you’re just starting…then loop the video. Make the run time total if, say, 60min. ✅ASMR-induced sleep: Mission accomplished !
Using a smaller ball and thinner copper structure would allow the ball to float longer. You and the audience would be able to see the interaction better, making it more satisfying and dramatic!

Just trying to look out for preventing health issues that's all :)
@@DJMetalstone you should wear a mask when in the room with any 3d printer. They all give off fumes. But with burning off the pla, you're going to be doing that outdoors, anyway, unless you're crazy, so fumes will be less of an issue.
@@ShadowMage3D well when he opened it up wouldn't the fumes get out right in your face ? Just wondering. Since it seems all is kinda trapped inside untill you open it up to keep the heat in. At least that's what it looked like.
Very cool build and process! I also gotta give you props for the details you put into your sound design- most people won't notice it consciously, but you can feel it.
Practical use of idea: miniature scale prototype. Hollow Copper tube 10ft long 10inch diameter. Inside on walls of tube place equally spaced negative to positive strips of magnetism equivalent length of copper tube. The passenger capsule will be the ultra powerful spherical magnet. Process of motion. Copper tube is to spin at a constant. Electric current is to run in the strips in the Copper tube. Each end of the Copper tube is to have a repelling force for the magnetic sphere aka the passenger capsule. Thus creating hyper-velocity from point A to point B. Congratulations. You have invented . A new transportation system.
Because the sphere is polygonal magnetically the magnet will see a bumpy surface, the join line being down the middle will make it even worse because the magnet only 'sees' loops of copper as electromagnets, and the join line breaks lots of loops of copper which ought to be there. This will make the centrifugal force problem much worse as the magnet is being effectively grabbed by the bumps. I think you could get the effect you want by making the sphere out of a series of copper rings held together by something non conductive. That way the symmetry isn't broken and the ball should levitate smoothly.
When I worked in a foundry, casting art pieces in bronze via the lost wax method predominantly, we used a compressed air gun with a small jack hammer like fitting to press against the sprue and vibrate the silica shell off of the actual piece thereby saving it from damage, and I can confirm that large pieces of shell falling off was most satisfying, as well as revealing the treasure inside of course. Great to see you doing it in what is essentially a backyard operation. We were a relatively small company and also made a lot of our own equipment including our furnace made inside an old 64 gallon drum.
Actually as it is have many holes , this really reduce eddy cuurent as resistance gets larger in the sphere thing and so the the magnet can not have the suspension force like in a solid cylinder so i think this is the most you can get out of it Also the split between the 2 Half's of the sphere reduce eddy current and increase resistivity as there is a layer of air between them ( even if they are touching it is higher resistant that the copper it self ) But awesome design non the less
@popofouad in my opinion the gab between the spheres reduces the current, maybe it would help, if he would use solder to close the gab (but you have to be careful, magnets doesn't realy like heat)
@@unknownxy8026The sphere is not a magnet. It only becomes one momentarily, when a magnetic force changes within or around it. So it should be totally fine to solder it
Best comment. The eddy's are being cut where they would naturally lie and it changes the properties. It need to be solid. Gonna have to look inside another way. At least you can hear if it's floating.
That's all kinds of cool, well done! Ideas: 1) Suspend the magnet in the middle of the sphere, then spin the outer sphere up with the drill before releasing it. Might get more levitation that way. 2) With the entire system spinning, hook up a voltmeter to the outer sphere and see what kind of voltage it generates. 3) Consume cookies.
@@sleeplessdev7204the small magnet is acting on the large magnet, the copper sphere is only moving because it goes out of balance when the magnet moves.
When sandblasting away the ceramic cones that lead to the sphere, if you blast them in a spiral you could get nice ceramic lamp pieces, candleholders and so on. Cones and cylinders lend themselves to very nice spiral making
Hope you can demostrat that the series found in Roman artifact aare actually wood fired heaters small twigs rock slab base rock surround as heat sink very little smoke vidio please
I've seen many videos. Your subject matter is impresive. You have mixed foundry with physics and video production all together with your own experience and interests. You have captured me as a follower.
For the ceramic being as hard as it is, it seemed like you were just blowing away fluffy marshmallow with the sand blaster. That was very satisfying to watch.
Incase it hasn't been brought up, make the inner space larger. Either thin the shell or just make it bigger, give the magnet more space, and time, to fall and thus be slowed.
A brilliant and entertaining piece. I defy anyone who starts watching this video to look away - you simply cannot. As soon as the video started I was on the edge of my seat waiting to see what would happen. As usual, the videography, lighting, editing, and narration were superb. It is always such a pleasure to sit down and spend a few minutes watching a true artist work. Bravo.
A dutch company called Zytec makes an industrial coupling with a magnetic and a copper disk to make a coupling with no physical connection between the motor and the driven part.
so cool. so much comment, i dont have time to read all but i have suggestions: 1. spin it vertically. 2. make the copper structure thinner for better visibility. 3. different copper structures.
Use a in frequency adjustable stroboscope light in complete darkness while it's rotating. That brings the copper sphere to "stop". Not only for the camera but also for your eyes. Great project, thanks 👍🏻
@4:25 You said, "Fortunately, most of the time it does (work out)." There's nothing fortunate about it. It's due to your meticulous planning and execution that it all goes well. It's one of the things that I appreciate about your channel.
You probably already know that what they previously termed the vacuum of space/dark matter is now known as boundless/ endless energy interacting with other energy of the same origin. That helps me to understand a little better. I'm fascinated by your work. Thank you for that insight.
YT just served your channel to me for the first time, as far as I know. As an electrical engineer, this was very interesting to watch and learn from. Thanks !! and yes, I am subscribing !
Good accomplishment there. Someone has already suggested a stroboscopic light to make the housing appear stationary, but you should be able to synchronise the rotational speed with your camera frame rate to give the same effect.
I'm trying to imagine how far we as a species would have become if all videos on UA-cam were like this instead of what it is now. It shows curiosity, experimentation and result. Everyone who saw this is a better person because of it.
Visionary stuff man. Great to see the mix of 3d printing and ceramic preliminaries. 1) Make the interior of the truncated dodecahedron spherical rather than polyhedral. That is, start with a sphere and poke nice holes in it. 2) Once you have a better setup with the drill spinner, match the rotation to the shutter speed so the cage isn't visibly rotating.
This is really cool, to fix the magnet falling issue if the copper plugs went inside of it a little more it would give the magnet something to grab onto when spinning, or don't have them be copper at all.
Try freezing the magnet. Reduce the magnet size about 1/3. Fill the holes with copper plugs, every other one, gradually take out one at time, spin, see if fully covering the sphere increases resistance.
This is extremely cool! I adore passion projects like this, going to all the trouble just to glimpse a few seconds of something you predicted could happen. Worth it! Subbed.
If you figure out an ideal speed, you could try synchronizing that with a strobe for filming the effect. The left over sprues could be made into candle sticks! Use the torroidal magnet attached to a motor to spin the sphere at just the right speed to make the magnet levitate?
This looks like something that would be good for occupational therapy or physical therapy with someone working on their hand and wrist grip strength. The way you describe all the ball doesn't react to the way you expected to would be perfect for the little fiber muscles. Even if it's not with such expensive material but making one out of a gel like you said it feels like would be helpful.
The magnet might float better if the two halves had a more ideal electrical connection. The eddie currents are probaly being interrupted at the seam. Maybe some more filing or you could TIG weld them together. This is really cool reguardless.
@@KafshakTashtak Use regular solder or silver solder, lower temp than brazing or welding. if the seams are tinned before soldering it will go quicker with less chance of major heat adsorption.
Make a base with a rotating magnet (hidden) at the right speed so the chamber spins with nothing connected to it, with a floating ball inside. I think that would look really cool.
Noticed when you were trying to get a better camera angle that the axis was a copper tube. Not sure how practical or if possible but it would be good to have an endoscope camera within the axis tube to get the internal view when it’s rotating.
Work on adjusting the speed and power settings on the drill you might be able to get it at the right revolution to achieve what you're after 😉 love the video can't wait to see where it goes
A strobing light will give the effect of outer sphere not turning so you’ll be able to see inside easily. Similar to a camera shutter making a helicopter look like the blades aren’t spinning.
You should induce the spin using an external magnet like you did at the end, but using a motor to spin the external magnet. This will keep the magnetic poles perpendicular to the axis of rotation of the cage. The inner magnet would then be spinning the cage rather than the cage spinning the magnet. It should float nicely then.
Kinda cool when a channel I've been following out of interest in metal casting commits to building an experiment that attempts to demonstrate a physics principal.
Really clever idea! You might try painting the copper black and playing with the shutter speed of the camera to get a stroboscope effect that will make the copper look like it's not rotating so fast. Alternately do a really slow shutter speed so the cage is a blur and the sphere stands out better since it moves slowly

Very cool build and process!
I also gotta give you props for the details you put into your sound design- most people won't notice it consciously, but you can feel it.
I noticed this too, really well done.
Practical use of idea: miniature scale prototype. Hollow Copper tube 10ft long 10inch diameter. Inside on walls of tube place equally spaced negative to positive strips of magnetism equivalent length of copper tube. The passenger capsule will be the ultra powerful spherical magnet. Process of motion. Copper tube is to spin at a constant. Electric current is to run in the strips in the Copper tube. Each end of the Copper tube is to have a repelling force for the magnetic sphere aka the passenger capsule. Thus creating hyper-velocity from point A to point B. Congratulations. You have invented . A new transportation system.
I would love to see it, miniature scale prototype
Did you just explain the transportation device in the movie, "Contact?"
9:58 Attach a motor.
V8 motors with jets
also attach some ball bearings
Right
@@BlackDeltaOneright?!
he did
Because the sphere is polygonal magnetically the magnet will see a bumpy surface, the join line being down the middle will make it even worse because the magnet only 'sees' loops of copper as electromagnets, and the join line breaks lots of loops of copper which ought to be there. This will make the centrifugal force problem much worse as the magnet is being effectively grabbed by the bumps.
I think you could get the effect you want by making the sphere out of a series of copper rings held together by something non conductive. That way the symmetry isn't broken and the ball should levitate smoothly.
Bussard fusion
Yes, probably a non polygonal circular surface would work better ... Still, I'm positively impressed
I think you may be on to something here; but I see half (slightly less than) circles connected together in end caps with copper screws
What if it was just a copper hollow sphere with holes drilled into it to see inside or slots cut out?!
What if it was more like a tyre or just a ring?
10:10 you should program a motor and expiriment with different speeds to try and get the ball to stay in the center of the truncated icosahedron
I agree
1:49 That was the ... only trades themed fondue montage I've ever seen. Well played (jazz and all)!
When I worked in a foundry, casting art pieces in bronze via the lost wax method predominantly, we used a compressed air gun with a small jack hammer like fitting to press against the sprue and vibrate the silica shell off of the actual piece thereby saving it from damage, and I can confirm that large pieces of shell falling off was most satisfying, as well as revealing the treasure inside of course. Great to see you doing it in what is essentially a backyard operation. We were a relatively small company and also made a lot of our own equipment including our furnace made inside an old 64 gallon drum.
Actually as it is have many holes , this really reduce eddy cuurent as resistance gets larger in the sphere thing and so the the magnet can not have the suspension force like in a solid cylinder so i think this is the most you can get out of it
Also the split between the 2 Half's of the sphere reduce eddy current and increase resistivity as there is a layer of air between them ( even if they are touching it is higher resistant that the copper it self )
But awesome design non the less
I wonder if "stripes" with a few supporting cross members instead of hexagons would have been better.
@popofouad in my opinion the gab between the spheres reduces the current, maybe it would help, if he would use solder to close the gab (but you have to be careful, magnets doesn't realy like heat)
@@unknownxy8026The sphere is not a magnet. It only becomes one momentarily, when a magnetic force changes within or around it. So it should be totally fine to solder it
I agree I think the split may be effecting it significantly, those two sides need to be brazed together
Best comment. The eddy's are being cut where they would naturally lie and it changes the properties. It need to be solid. Gonna have to look inside another way. At least you can hear if it's floating.
That's all kinds of cool, well done!
Ideas:
1) Suspend the magnet in the middle of the sphere, then spin the outer sphere up with the drill before releasing it. Might get more levitation that way.
2) With the entire system spinning, hook up a voltmeter to the outer sphere and see what kind of voltage it generates.
3) Consume cookies.
You might need to make the stand connector piece metal to have somewhere to connect but the voltmeter is such a good idea.
#1 is what I was thinking: Point some air jets to the magnet to make it levitate and remove the initial friction between tha magnet and the cage.
A lot of prep work goes into this experiment. What did you do with that copper sphere afterward? That's a piece of art!
11:46 - this is more interesting than floating sphere for me
Agreed, I'm surprised the small magnet is able to rotate something so heavy from such a distance.
I'd love to learn more about how that works!
And will the small magnet still rotate the sphere if it doesn't have the spherical magnet inside?
@@sleeplessdev7204the small magnet is acting on the large magnet, the copper sphere is only moving because it goes out of balance when the magnet moves.
Maybe it can be used for wireless mechanical gear?
Put it on a scale and spin it

Incase it hasn't been brought up, make the inner space larger. Either thin the shell or just make it bigger, give the magnet more space, and time, to fall and thus be slowed.
A brilliant and entertaining piece. I defy anyone who starts watching this video to look away - you simply cannot. As soon as the video started I was on the edge of my seat waiting to see what would happen. As usual, the videography, lighting, editing, and narration were superb. It is always such a pleasure to sit down and spend a few minutes watching a true artist work. Bravo.
A true artist amongst all the other you-tube jerks
Idea: Get a motor you can precisely tune the rotation speed, and a strobe light triggering every 72° of the shaft rotation.
Rotating the copper sphere with the other magnet is something akin to a differential. Very cool.
Magnetic torque converter- could make one with variable magnetic proximity so as to be a clutch/torque converter in one. Good for a gokart.
A dutch company called Zytec makes an industrial coupling with a magnetic and a copper disk to make a coupling with no physical connection between the motor and the driven part.
Don't show this to Dyson. We will end up with really odd vacuum cleaners labeled with pacemaker warnings.

I love that you can see the layer lines in the copper

Use a in frequency adjustable stroboscope light in complete darkness while it's rotating. That brings the copper sphere to "stop". Not only for the camera but also for your eyes.
Great project, thanks 👍🏻

Good accomplishment there. Someone has already suggested a stroboscopic light to make the housing appear stationary, but you should be able to synchronise the rotational speed with your camera frame rate to give the same effect.

You could use a strobe light to make the magnet seem to float in the centre. You could link the setup to a small wind turbine for quieter propulsion.
Visionary stuff man. Great to see the mix of 3d printing and ceramic preliminaries.
1) Make the interior of the truncated dodecahedron spherical rather than polyhedral. That is, start with a sphere and poke nice holes in it.
2) Once you have a better setup with the drill spinner, match the rotation to the shutter speed so the cage isn't visibly rotating.
That is one of the coolest projects I’ve seen on UA-cam. Nice job!
I can't believe how heat resistant that ceramic shell is. very cool process. and great video!! thanks for sharing!
Nice! To see it better, you could try a uniform copper structure with larger volume with larger voids.

This is really cool, to fix the magnet falling issue if the copper plugs went inside of it a little more it would give the magnet something to grab onto when spinning, or don't have them be copper at all.
Try freezing the magnet. Reduce the magnet size about 1/3. Fill the holes with copper plugs, every other one, gradually take out one at time, spin, see if fully covering the sphere increases resistance.
Okay, so the making of the sphere was so very satisfying. Well done.
This is extremely cool! I adore passion projects like this, going to all the trouble just to glimpse a few seconds of something you predicted could happen. Worth it! Subbed.
I love what your are doing.....Over the top ....we can learn even more...please continue...I am interesting of the results.
So many people are saying to use a motor while here it is he is using a drill 10:32
A drill is just a motor designed to drill/screw
A motor will hold it at a consistent speed.
Dude just randomly designing Satisfactory-Warp Core... thingy sh*t...
that sphere will take you to where no man has gone before
If you figure out an ideal speed, you could try synchronizing that with a strobe for filming the effect.
The left over sprues could be made into candle sticks!
Use the torroidal magnet attached to a motor to spin the sphere at just the right speed to make the magnet levitate?
This looks like something that would be good for occupational therapy or physical therapy with someone working on their hand and wrist grip strength. The way you describe all the ball doesn't react to the way you expected to would be perfect for the little fiber muscles. Even if it's not with such expensive material but making one out of a gel like you said it feels like would be helpful.
The magnet might float better if the two halves had a more ideal electrical connection. The eddie currents are probaly being interrupted at the seam. Maybe some more filing or you could TIG weld them together. This is really cool reguardless.
I thought about him welding or brazing them. The problem is that the heat will spread quickly through the copper, and that might anneal the magnet.
@@KafshakTashtak Some conductive putty might help increasing the contact area.
@@KafshakTashtak Use regular solder or silver solder, lower temp than brazing or welding. if the seams are tinned before soldering it will go quicker with less chance of major heat adsorption.
Would it help to solder the two half's together?
Make a base with a rotating magnet (hidden) at the right speed so the chamber spins with nothing connected to it, with a floating ball inside. I think that would look really cool.
I so wish my brain could be this creative, precise and accurate
Wow you just did all of it for us thank you!
Interesting video!!!
Bro. Watching Dan da dan then seeing your thumbnail. It's too much 😂. Great video!!
I actually binged the show in a day
0:28 does that make contactless bearings possible? What's the drag like?
I think bro is onto something
No because the eddy currents generate heat in the metal.
Would probably melt itself if it went too fast
@@Andrew-vr5bb just don't go too fast
Contactless, yes, drag-less - no.
Magnetic bearings already exist, this is just a derivative of one
Noticed when you were trying to get a better camera angle that the axis was a copper tube. Not sure how practical or if possible but it would be good to have an endoscope camera within the axis tube to get the internal view when it’s rotating.
what if you had an endless copper tube with that ball in it? Would the ball stay perpetually suspended?
Work on adjusting the speed and power settings on the drill you might be able to get it at the right revolution to achieve what you're after 😉 love the video can't wait to see where it goes
What do you think will happen? And if you’re enjoying the video, don’t forget to hit the 👍- it really helps the channel out!
Maybe try a larger copper "sphere" or a smaller magnet.
A strobing light will give the effect of outer sphere not turning so you’ll be able to see inside easily. Similar to a camera shutter making a helicopter look like the blades aren’t spinning.
@@seanbaker1627 Great idea!
soccer ball
You should induce the spin using an external magnet like you did at the end, but using a motor to spin the external magnet. This will keep the magnetic poles perpendicular to the axis of rotation of the cage. The inner magnet would then be spinning the cage rather than the cage spinning the magnet. It should float nicely then.
Kinda cool when a channel I've been following out of interest in metal casting commits to building an experiment that attempts to demonstrate a physics principal.
That copper isocosawhateveritscalled is freaking gorgeous! Beautiful work.
