As a chemist I have my doubts about the amount of ferric chloride you had managed to "concentrate" in your glass. I bet you could repeat this experiment with regular tap water, or hell, even distilled water, and you would get very similar results. The reaction you are doing is actually between the water, the copper and *oxygen* from the air. The oxygen oxidizes the copper and the copper ions are dissolved in the water in the form of an aqua-complex (light blue color). This is a very slow reaction at room temperature, happening only over days/weeks/months. The process will lower the pH, and without any acid present the solution very quickly saturates, so I would expect this "etchant" has a very low copper carrying capacity. I would really like to see you try straight tap water, tap water that has been boiled (to drive off free chlorine), distilled water, and "concentrated" tap water. BTW you could also try vinegar (in a separate batch, otherwise it might contaminate the other samples slightly), I would expect that it would etch way faster than any of the water samples.

I am not interested in etching a PCB, but using the same strategy, I found that there is trace amounts of whiskey in drinking water. Since alcohol is lighter than water, I took a gallon jug and filled it with tap water and let it sit for several hours. At the end, there was a slight, but discernible, slick of amber liquid on the top of the water. I drew it off and repeated this 10 times with 10 different fills of water. In the end, I got about 1/2 ounce of whiskey. I did a taste test with my Jameson's Irish and, was pleased to find it was similar. Since more people drink scotch, I think my free whiskey is probably more Johnny Walker than Jamesons. Great tip, thanks!

A far better method is to use bose-einstein condensate after processing with an ion implantation filter.

Lived in Flint most of my life, don't find it funny but your right. Other than lead contamination the water here has a truly insane amount of chlorine present. So much that a freshly drawn glass smells more like a swimming pool than potable water. My mother taught me very early on how to distill water even though she didn't know that was actually what she was doing. My father taught me to do so with a filtered picture. Still I preferred drinking juices, pop or using the filtered and distilled water to make tea. Always found tea taste so much better after filtering and distilling it. However etching a PCB with our water is inadvisable for another reason and no it's not the lead. We have serious problems with lime scale buildup. A fresh tap screen will last about a week or two before it starts to get wonky. Shower heads I have to tear apart monthly to get all the buildup out of them, usually grab a needle to punch the buildup out of the dispenser holes. I have in my basement right now a piece of PVC pipe with so much lime scale in it that you can not pour water through it. So yeah, plenty of chlorine to etch a PCB, but your going to need a chisel to find it after the lime scale deposits all over it.

Dave, I've tried it here in the Netherlands but it doesn't seem to work. Afterwards I failed to test it by turning the magnet around, because it might be due to the fact that you're on the negative half of the hemisphere. I'm also looking into the possibility that I needed to wait until the water from the tap stops spinning up here on the other half. Maybe the prions incorrect rotation over the magnetic field could cause an oposite reaction. I found that the copperlayer had become significantly thicker on the exposed parts.

So I am no expert, but I have done several dozen etches with both ferric chloride, and hydrochloric acid + hydrogen peroxide. I use photoresist, but have also done marker boards and toner transfers. Currently I design and etch 2-5 boards a month. I have tested all of my different Sharpie markers on the buffer margins of my boards while etching. I have tried black, red, green, blue, yellow, and silver. I also have several of the cheap black Chinese art supply markers that are sold for pcb etching on AliEx/eBay. The Chinese markers work reasonably well. They don't cover the applied area 100%. By this I mean, even after coating/drawing a trace multiple times until the area appears completely (ridiculously over-) covered, the etchant will still cause small perforations and imperfections through the marked areas. These are usually very small, randomly distributed and non-critical IMO. I get similar results when I do a toner transfer based etch. However, Sharpie's are in whole different league of crap. Black will barely mask anything useful. By the time my etch is complete for a photoresist setup with Sharpie in the margins, the black Sharpie is 50-60% compromised. The area is so poorly masked I have zero confidence that the trace is capable of whatever current capabilities the copper clad/trace width was designed for. It's so bad that, despite thoroughly cleaning and adding copious amounts of flux, it is virtually impossible to uniformly cover the area/trace in solder. My post etch cleaning routine is identical to my photoresist prep clean, works well, and is loosely based on the Dupont Riston dry film photoresist datasheet. The 50-60% masked results for black Sharpie were my best results with several different black Sharpie markers (all branded, but different packaging/tip variations sold). The other colors are far worse. Blue left around 25-35% of the margin materials by the end of the etch, Red left around 10-15%, Yellow was totally etched away. Silver causes some kind of terrible chemical reaction that causes the copper to react and form a rainbow of colors along with a weird textured alloy/oxide layer that is probably toxic by the looks of it. They are all pretty much useless junk IMO after thoroughly testing them. If all I had were Sharpie markers to do a junk prototype that is non-critical, I'd still go get a better alternative or wait. The Chinese markers aren't great. They dry up fast and are a pain. If you want to buy 1, don't, buy 10. Sharpie's are dye based media. You need a real marker instead, something that leaves a physical waterproof dried substrate on the surface not a thin dye that intended to soak or penetrate. Perhaps I could get better results by just using a Sharpie by itself. Maybe the etch time is just much shorter and it gets slightly less degraded somehow (doubtful). I have compared the black Sharpie to the Chinese markers on the same board margins. There is no real comparison, the Chinese markers are several orders of magnitude better than a Sharpie. Personally I consider the 'just use a sharpie' advice as complete nonsense in practice. I've yet to find anyone demonstrably etch a useful design using one. Even this board shown was removed before it was completely etched as would be required with a real design, and yet the sides of the covered areas are clearly compromised already, and even with the limited viewing angle, after cleaning, the body of the masked region shows signs of the etchant penetrating the mask considerably. In my experience, these problems only get worse at the very end of the etch. Even if the last 2% of copper remaining is ignored in favor of using an art knife post-etch (something I occasionally do with tight photoresist designs) the Sharpie is useless garbage by this stage. Of course these are just my experience/experiments. I've thought about uploading some results like this but I'm more embarrassed about the sad state of early designs and such. Maybe I will one day soon though. Thanks for the upload and ideas. -Jake

Of course there are natural additions to the water that an experimenter can supplement to enhance the etching effect. Steer manure is just an example of a natural additive that increases the effect.

I know Dave usually does an April fools joke so I came over to his channel to see what he would do this year, and no joke this year, I guess when you do one every year everyone know you will do one and it gets difficult, but as I say no joke on Dave's channel this year but we have this great bit of research , which again is something Davy boy is know for, so good on you cobber, ripper bit of research. Pity you didn't do an April fools joke, but I think in a way this is better.

Ahh, memories. I remember i used to sneak spinach off the dinner table to etch my boards. Convinced my mom I was iron deficient so she'd make it more often.

Always important to reinforce the dangers of Dihydrogen Oxide: It can kill! Well done, Almost kept your composure but nearly lost it 5:40 (just afterwards maybe 5 51s). Thanks - Good effort :)

This can't be right. According to flat eathers Australia doesn't exist and Dave is an actor and not an EE. ;)

I think he used sodium persulfate (Na2 S2 O8). Commercially avalable as B327 for PCB etching, not very popular in most of the world. It is transparent when mixed with water before first use, turns blue when copper gets dissolved. His solution looks weak as it is pretty fast when heated that high and mine turns more blue. Much safer for use at home as it is clean and won't stain everything as ferric chloride. Very cheap too.
