Just shows a process to construct a copper cone shape with electricity, copper metal and an acidic copper sulfate electrolyte. this process is similar to copper plating except the layer of metal is deposited many times thicker. - วิทยาศาสตร์และเทคโนโลยี
okay I have to say this is very impressive!
That is really freaking awesome :)
AMZING! :-D It's magic!!
YOU ARE A GENIOUS! PULSE NEON.
SINCERELY.
Cabrondio VITRIOLVM credit for this idea goes to Sciencemadness user gnitseretni. He came up with the concept. I have only added my touch and filmed it.
@@PolishChemist1 Il see if I can locate it

How did you cut the copper pipe lengthwise??
Would it be possible to do this but instead of using the steel cone with silver conductive paint, could you use a cone (or any other shape really) made of aluminum foil? Or would aluminum foil dissolve in the acidic solution?
n00b3rpwn4g3 a thin layer of Al would likely dissolve. Al forms do plate though. I have successfully plated Al fence caps with this method and also cones made from car body filler coated in the silver paint. It may be possible to create a form using epoxy and graphite powder though.
May I ask in which country you live?
Instead of silver paint we can substitute with gharphite powder and acetone mixing them , and then painting it all over the cone.
I just saw the same process was done for making conductable 3D prints.
Probably not. Acetone will evaporate and powder will fall off.
3d printing makes this 2.68 • 10⁵ times easier that using any random piece of junk with the correct angle as a mandrel.
Graphite CAN work, I've seen it before on videos ... But I've never been able to get it to work using graphite. Just buy nickel conductive paint from MG chemical. It's 1/3 the price of silver paint , and it's only a tiny bit less conductive
During the electrolysis, did you cover the cone with a balloon? It's not very clear from the video..
Looks like maybe masking tape to mark the edge and also protect wiring.
Would the silver paint have to be reapplied if you wanted to do this a second time with the same steel cone?
Yes
how about use a chatge to press a copper cone, like flashpowder maybe
i think going mechanical is the practical way to go, but its a very nice result. in reality, aluminium works maybe 80% just as well if i remember it correctly with some slight differences in properties
WeebRemover 4500 I’ve tried mechanical means several times with the limited equipment I have and I’d say that this way has gotten me the best results so far. It’s quite easy, repeatable and can be varied to form any shape or angle required. Just slower that’s all. As for Aluminium, they use it for punching holes in concrete or glass in military applications. Steel penetration is quite minimal.
What's the purpose of the silver paint? I assume that at the low level of current you're using, the steel cathode is conductive enough, so perhaps the paint just prevents the electrodeposited copper from sticking to the steel cathode?
Harold Smith yes. The paint does increase the conductivity and is mainly there to provide a layer to make the cone easier to remove. Also the steel is quickly attacked by the acidic solution and I found it he copper doesn’t stick in places. The copper layer starts immediately on the silver paint and prevents this attack.
AllChemystery your vids could be great but they are edited by a moron. Or, lack editing.....no fucker wants to want your boring ass dab fucking paint like a classroom full of special kids!
If your videos were made more consice you would have a lot more fans, as it it....your videos are hella boring to watch
Shona O'Neill wake up on the wrong side of the bed this morning? Nobody’s forcing you to watch..... the silver paint is part of the process and if I did not show it then I would have missed an important part of the whole process.
@@AllChemystery but the comment is not wrong. We watch you dab paint like Michael J Fox all day long and yet you fail to show the application of tape to form your parting line nor do you explain why conductive paint is necessary to the project or how the electroplating process works or what would happen if the transformer leads were connected in reverse polarity, just in case some curious child didnt know how to make the basics of a simple standoff shape charge to be used in his or hers next show n tell day at terrorist kiddy camp! Get this shit off the innernet hack boy!
@@ricaurandt6713 I cannot tell if your comment is meant to be sarcasm, but there's a very apparent reason why detail is not largely supplemented. He doesn't want videos to be taken down say the wrong video gets too much publicity or gives away too much information. Be happy that someone has given their time to make the video for your leisure in the first place.
if copper cone is machined on a lathe or stamped and then annealed how would it perform?
It would perform as any other but it would be remarkably inefficiency compared to how easy and precise this process is.
:)
would currents as high as tens of amps impact cone performance?
yes. you would burn it and probably just end up with a crumbly blackened cone shape that would just fall to bits. you need low voltages and low currents for this to work well. obviously a lathe machined cone would work well but good luck! lathe work to make a cone is tricky. spin forming is also a very good way to decent cones. stamping them will work but the size and thickness is limited due to stretching and tearing that may happen with pointy mandrels needed to do it. if you have decent forms and can wait a couple days this is probably the best method.
I have had success using car body filler in a plastic funnel to make the form and painted it with the silver paint and they worked fine.
Is it possible to plate graphite with this solution ?
the 25ml H2SO4 concentrated you listed - how many percent?
Jala Penos it’s 98% however the exact concentration is unimportant.
@@AllChemystery Thank you! Btw - do you know how to make DIY polycarbonate (or similar liquid resin that will harden in a mold) /a way to recycle plasic this way.?
That’s is so damn cool! Where do you get the solution?
这是什么操作😜
What are you gonna do with that cone
I still have it.
