Electrolysis is a useful skill to pick up and the beauty of it is that it's super easy to do. Electrolysis can be used to plate materials, to clean, for etching and even to produce pure forms of a material.

In this article we'll show you how to make your own small electrolysis kit. With what you'll learn you'll be able to scale up the kit if you wanted to.

Step 1: Materials Needed

List of materials:

  • Crocodile clips
  • A battery
  • Some pencils
  • A non-conductive container
  • A knife
  • A pair of snipe nose pliers
  • A piece of card (big enough to go over the top of the container)
how about i change the batrai with usb cable ?
<p>Here's a video explaining how electrolysis work, I really recommend it!</p><p>https://www.youtube.com/watch?v=URFtlXd0AxA</p>
to upsize you could buy some graphite rods here http://www.mcmaster.com/#graphite/=ohdxsf
I can't see the video
I have embedded the video at the start and end of the instructable and it appears fine for me. If it's not showing properly for you on this site try visiting our Youtube channel <a href="http://www.youtube.com/user/GoRepairs" rel="nofollow">http://www.youtube.com/user/GoRepairs</a>
it would have been a better idea that instead of having it cut by a knife, just burn it. <br>The wood will burn and the graphite will stay there.
I wouldn't say that burning was any better - a different way yes.
the lead will be a bit soft.that's the only problem. it is only to insert it in water... that's
Cool. I once tried to light an led by drawing pencil lead, having an led at the end of the trail, and connecting a battery to the lead, but it didn't work out. Here is the video on this concept: http://www.youtube.com/watch?v=BwKQ9Idq9FM
This is something that I did as a kid long ago and had fun with it till I electroplated things that Ma liked to have in the colour she bought it. It cost me a long time to get the plating off in the intrinsic nooks and corners on her dust collecting figurerines
I know what you mean, once you start you wonder what you can do next.
OK? So where's the end that you would use to say &quot;etch&quot; with? (or anything else) I think that a working end should be part of any kit. <br> <br>I understand as far as it goes and you explained well.
Hi, thanks for commenting. The idea of the article was to be a basic introduction to electrolysis. With this simple kit you can start to learn about the process and hopefully you will want to learn more. At some point in the future I will put up another article (maybe an intermediate level) which will be slightly more advanced than this.
Looking forward to it! I'm especially interested in plating jewelry, and other jewelry making applications. Pinning this... its really intriguing and informative!
I'm glad you liked it.
as a retired science teacher I find this Instructable to be clearly and elegantly presented <br>
Thank you for your kind words.
Nice presentation! What kinds of solutions can be used for this process? Can I clean jewelry using this process? Can I use this process to tin a circuit board, and how can that be done? Thanks
I will hopefully go into the applications more in the future - cleaning, plating etc.
how do I get my legs in there?
You mention 'solution' - what is your solution that you used in the glass jar? Just water??
When I mentioned you would dip your pencil probes into the 'solution', I'm referring to whatever you want to do electrolysis with. In the video I was using water (the clear liquid) and copper sulphate (the blue solution).
Neat, and went to my Blog: <br>http://faz-voce-mesmo.blogspot.pt/2013/08/um-digitalizador-3d-uma.html
Thanks I appreciate the support.
Tou don't state what the solution is, or indeed what you've transferred to/ electroplated the pencil with
Yes your right I don't, the reason is it's not a 'How To Do Electrolysis'. This is a how to make a small home electrolysis kit. But if your interested, the examples in the video were water (clear solution) and copper sulphate (the blue solution). I may go further into the details of electrolysis in the future. Thanks for leaving a comment.
No problem.
We got a new parts cleaner in our bike shop and it cleans parts by creating electrical currents through the water. I really never looked into it but is this pretty much the same thing?
Yes by the sounds of it you are using electrolysis to clean those parts.
I like it! Short sweet and to the point. Now, make a few more showing the applications, like plating, etching, etc... keep up the good work.
