Hello Cody, I have a recommendation that would likely work better. Instead of boiling water using a torch and sending steam into the carbon, send the torch flame directly into the tube that goes into the furnace. The exhaust of a properly tuned torch has a huge amount of water vapor in it, and some carbon dioxide, while containing little to no oxygen. Propane is C3H8; when fully combusted, each propane molecule results in four water molecules and three carbon dioxide molecules. Both carbon dioxide and water vapor will carry out reduction reactions that pit the charcoal and increase its surface area; hot carbon dioxide gives up one of its oxygens upon striking charcoal, resulting in two carbon monoxides. Reduction reactions are way more efficient at higher temperatures, and the exhaust of a torch is far hotter than the steam you were using. I work at a micro-scale biomass gasifier company. The charcoal produced by our reactors passes through a 600-800˚C reduction zone, and was lab tested to have 496 m^2 of surface area per gram. Try using the torch flame itself as the source of the reduction gases. Insulate the tube that feeds your reaction chamber; the hotter the gases, the more efficiently the reduction occurs. Since all the reduction reactions are endothermic, making the gas hotter gives it more energy to carry out the reduction reactions.
Holy shit, you are too over qualified to comment

Awesome tip from someone with domain knowledge - thanks!
Thank you.
3:15 "Accidentally ingest a poison..." OH BOY! A crazy video coming soon!
Cody has already built up an immunity to all poisons so not sure why he'd need the activated charcoal

Every substance is a poison, don't forget that.
Super memories here. My first job was with a company making smokeless fuel. Our lab did everything from tar-analysis to pollution measurement to weather-recording (wind direction records were used to measure dust-particle fallout from chimneys). That was all back in the 70s when virtually everything was gravimetric. Weighing scales, the ones that used counterweights and burettes were daily tools. Titration of multiple samples was incredibly boring but more than compensated for with our sample collecting. Taking water samples from rivers included measuring its flowrate. Dust sampling units were scattered over a wide area and the wind-direction data allowed us to map the deposition rates. This video mentioned water-gas. We produced a good amount of that and its a rare thing to hear about. I loved that work and the people that did it.
That's going into details!
Triple beams are a fond memory of my chem classes before they remodeled and I'm not even 25 haha
I was searching for a DIY activated carbon recipe and most of the content I saw was nonsense. This video was 100x better than anything else out there. Now I actually understand what the heck activated carbon is, and how to make it. Awesome content. Subscribed. :)
Yes, Cody is really good at explaining and demonstrating even complicated stuff in a way anyone can understand. And always in a communicative good mood :)
Ads are making this unwatchable. Cant cody do without the 50€ a month he gets for being annoying?
How to turn 20 min video into 30 unwatchable with ads. Great job cody. Respect to your knowledge though Shame for the moneyhunger you clearly dont need.

Touches mercury with bare hands, touches charcoal with gloves
yes charcoal makes your hands black and metal mercury is not really that poisonous and rolls off your skin
You gotta have your priorities...
Jayko30 Christ, leave me alone. I just want likes
@Ungregistered User r/iamverysmart
Two sets of gloves.
You perform the most sketchy yet professional experiments
So true, especially anything with mercury...
@Forsworn He knows what he is doing, don't worry.

InXLsisDeo thats a strawman
"You'd much rather eat 10g of activated carbon than 1kg of charcoal." A while back, I ran some numbers, and based on the LD50 for rats, 0.5kg of charcoal is the LD50 for a typical adult. So yes, I would much rather eat 10g of activated carbon than twice the median lethal dose for an adult human.
THE MORE YOU KNOW
Normally, I'd be concerned that someone would use this info for bad things, but I'm doubtful someone could force themselves to consume even a half kilo of charcoal at once, much less a full kilo. Besides, Cody literally drank cyanide once.
@@ComradePhoenix *in two weeks* Lower tier KZheadr: Hey welcome guys to the charcoal challenge...
Someone wouldnt have even been able to eat all that all at once
There's a guy that ate sunflower charcoal, he said it tastes decent.
I still consider this one of the best science videos on youtube. I've worked with charcoal and biochar for a few years and this was when I first saw it last year and still is the best analysis of charcoal or activated carbon out there. Thanks for doing this stuff dude.
all codes found in the video: aYeFTCWplkE 04co79X56dE FgJZA7c7Z9c Z79W0PkJzQ0 WbCjPLGcM_k They are all unlisted videos with additional content.
Legend, thanks Paul!
I came to the comments just for this. :)
Yay, I was right and thx for all the codes. That would have been almost impossible to get on mobile
And here I thought they were chemical compounds. I just did not take the time to read any, or I would have known that was not the case.
Where did you find them?
Cody has done some crazy unpleasant stuff for the channel, but a titration? Willingly? What a madman!
It's worse than that: *Four* titrations.
[unpleasant memories of highschool labs intensify]
Titration is just a massive pain. Crucial yes but UGGGGGHHHHHHH
That's sorta why we love him!
He is a madlad
Big piece of advice on making this product. When sifting run a magnet though the powder. This will remove metals. Use this especially if buying store bought charcoal. It will pick up rust and sometimes through the process of manufacturers a decent amount of metals can get into the charcoal since it is is compressed powdered charcoal you never really know what's in it. If your magnet picks up a lot of metals scrap it and start over.
I really like this hands-on approach to explaining how the process works on a microscopic level. It makes the explanation intuitive without leaving out important details such as the effect of kinetics and impurities on the reaction.
Thanks for the kindergarten visual explanation for us plebeians
@100% Drunk yes even if you're 100% drunk. he still makes it understandable lol
feynman method
It's made for Americans with no education, so basically for all.
Explaining charcoal using clay, did Cody want the audience to react?
Cody should become a science teacher
Cody, this is one of the best videos you have ever produced!!!! You have used stoichiometry and mass balance in the past, but this was a true experiment, showing the difference between a control and three different test substances. Each step, including the screening of particle size was well planned out. It also has very practical real-world applications. For example, the Keurig that sits on my countertop has an activated carbon filter to remove taste-related chemicals prior to brewing. Thanks for a really excellent video!
The production of CO and H2 during this process reminds me of the previous method by which H2 gas was mass produced, by passing steam over red-hot iron. The oxygen from the H2O combines with Fe, thus liberating H2. Over 240 years ago, Antoine Lavoisier used this method to help prove the conservation of mass in chemical reactions and to pioneer the concept of stoichiometry.
thallok replacing my Keurig charcoal was what actually made me watch this video lol
This is amazing Cody, you’re much appreciated for sharing this project
Hey Cody hope everything’s going well I’ve been watching you for a long time and i can put your videos on while i work on my projects any day of the week thanks for your videos they are very humbling and this is stuff i wish my friends talked about but i have ignorant friends so your my go to guy!

Commercial labs use it a lot, to the point of having machines that do it automatically. (They break down a lot)
At least your class actually taught Chemistry and not just Atomic Theory and Molecular nomenclature.
I love the experiments, man! Keep it up! I'm truly fascinated by almost everything you do. I guess it brings out my inner geek.
Hi Cody, you just answered a decade old question in my mind about this notion of "activated carbon". Thanks
Always wondered what made activated carbon activated carbon I was going to Google it but I kept pushing it off and procrastinating for no real reason and then I saw this video I'm glad I learned it here instead of just on Google
nice run on sentence
Liam Corder run-on
I did google it before but Cody explained it a lot better and simpler
Basically my view towards any other scientific topic, googling it yourself often times causes more questions than answers, thus causing more confusion and more procrastination the next time you try to google something similar
Yeah, but do you do with it?
Really like the clay model, Really good for visualizing the actual reaction.
@G W Pardon?
Loved your science this episode cody. Did a great job of presenting your results!
This is fricking awesome. I don't know too much about chemistry so your videos feel like magic to me! Really entertaining and educating.
Cody, have you ever thought about planting morel mushroom spores around your garden? Considering the advances made in cultivation and its sale price of 80 dollars a pound it would be interesting. The yard you have looks ideal for it. EDIT: the yard at your house. Not so good at the ranch unless you're there almost every day in the spring.
I love this so much Not just a method of how to make activated carbon But also a test to find exactly how activated it is
Cody. the reason i come back is that you are the only person i find saying things like, 'and keep in mind there may be significant margin of error here, but it was at least comparable'. humble skill is rare, and so is integrity. you sir are a fine example of both
Very informative. This is good information. Thank you for taking the time to produce this KZhead.
Cody: touches mercury with bare hands, draws diagrams with gloves

@@onyxguardian1756 Alcohol, even hand sanitizer will remove pen ink.
@@davidgalbraith1840 Twas a joke, about how he will handle (potentially) dangerous materials bare handed, yet wear gloves for handling a marker.
It's because he can handle one mercury, but the marker is made of two mercuries. Add a whiteboard to the mix, and we have even more mercuries.
Loving that new format, more explaining, nicely done!
Is it new?

@@Internetzspacezshipz millennium* millennia is plural.

New? There's nothing new about this video. Maybe you haven't been watching Cody's videos for very long. Because the past couple of years, he's gotten lazy. He doesn't put out videos, and the ones he does are short. I don't know WTF he's doing, or why he's not been doing more/longer videos. This is the first like this in a while.
I have the same activated charcoal. I have always wanted to see a DIY approach to making your own and how it compares to normal lump charcoal. This video helped answer a lot of questions I had. Thank you.
Awesome video. Thank you for your time and effort!
Cody, I just wanted to express my appreciation for your videos. I always learn something

Good job Cody! I give you some tips. 1) the woodbased charcoal developes normally a small surface without activating agent by self gasification. You have made what is called "physical activation" with steam but can be done also with carbon dioxide. During the carbonization is developed some CO2 that self activate the carbon to some extent. Different pore size distribution by the way you normally obtain with CO2 generating more micropores while steam as you described in the plastiline examples favors the production of mesopores (2
davide can u suggest a simple and efficient method in detail, want to make activated carbon fabric at home, ( if possible)
davide can u upload a flowchart or something please man.
As always a great and complete video. Keep up the good work
Big congratulations, I am very impressed !
Ah man Cody you beat me to it! I was just working on making activated carbon from hardwood myself! Great video as always 👍
sorry about that. perhaps you could show a different method? If you do I'll be happy to link to it in the description.
Sounds good! Keep up the awesome content!
Stop messing about with charcoal and build that N2O4 and N2H4 rocket already!?! Lub ya both
Another great video. So useful for air and water purification.
also for homemade gas mask
Try Shungite for water cleaning instead.

Underrated comment lmao
lololol
When titrating iodine it pays to use starch as an indicator. The change from dark blue to colourless makes the endpoint much clearer than the slow fading out of yellow you were dealing with. This would also be much clearer on camera. Nonetheless, good work as always!
Out was vey clear on camera. It went from yellow to clear.
In one of the “hidden” videos I flashed links for I used starch but I did not notice an increase in accuracy so I omitted it for the final. I always try to reduce instructions as much as possible.
@@theCodyReeder Hidden videos? All this sneaky business! :-D The unnoticeable difference in accuracy may be related to the relatively high concentration of the thiosulphate solution used in the titration. 0.7mL is quite a small volume to be titrating with a burette of that size, so I still think starch would help if the precision of your measurement was of greater importance. But of course, you did it and it worked to demonstrate the efficacy of your homemade product! I really love your work and I'm only a teeny bit jealous that with my urban location in Germany it would be exceedingly difficult for me to get away with even half of the experiments that you carry out! Someday I'd like to post a few practical science videos of my own but selecting the subject matter is proving a little tricky, for the above reason.
@@AguaFluorida you forgot that starch isn't an optimal indicator, it uses up "a lot" of thiosulpate for it to change color: to have a more noticeable change in color than the yellow-transparent in the video you have to add some mL of starch solution, in a reaction that only uses only 0.7 mL of (S2O3)2- solution it can cause an increase up to 0.5mL, with an enormous error! In fact it said to add starch only at the end of the titration to be able to see a little better the final part of the change, if you add it at the beginning it uses up reagents
@@8paolo96 Great reply, I'm glad to have stimulated a worthwhile discussion. =b

seriously one of the finest creators on youtube! Thanks again for the help, Cody!
Really enjoy your scientific process and estimation on your home made materials. Really cool
I would have added another sample: steam-heating the store bought one to see if I could make it more activated. Very interesting video by the way.
I know there are plenty of amazing science channels like Periodic Videos, etc. This one is up there with them. Truly remarkable.

I like how you explain the pores using the clay, and the experiment process. Even someone who's really bad with chemistry could understand. If my highschool teacher can explain things your way (clay is not expensive!) I would probably not fail my chemistry (and science) in high school!
I don't know why but the sound and feel of the charcoal rubbing around gives me crazy goosebumps!

Almost sounds like glass.
I've been trying to find a good way to make that. So thank you that I came across your video on this. I was close to just stop trying. You can can get a new paint can with the lid, put really small holes in the lid like 2 or 3 in center of lid and put it in the middle of your bon fire or pit fire to make your own biochar. If I want a lot more I just go over to my brother's place and he makes gallons of it at a time. It takes him around 4 to 5 hours to make a big batch. He uses I for his gardens and his fruit trees and stuff along with dissolved fish water. His stuff grows fast and bigger than the weeds can do. Lol.

Indra Verhoeven; do you know what asbestos is? they don’t use it much anymore but breathing asbestos dust causes mesothelioma. charcoal dust is bad too. it’s worse than just regular organic dust that the immune system can break down.
Cody a great tip for bending tube like that is to fill it full of water, cap an end, and freeze it. The ice will prevent the tube from collapsing. Plus it's much easier to clean up : )
Though a lot slower for it to freeze compared to letting the metal solidify.
I was told/showed by plumber that you can use sand
I've heard that packing a tube with sand before bending will keep it from kinking. I haven't tried that myself though.
could do the same with galium and not have to cap it plus galium is always fun
Reeally nice video. Your commitment and passion to science keeps amazing me for years now
To bend metal tubing, securely close the 1 end, tightly pack the cavity with fine sand & seal the other end too. Now you can bend the tubing without having the tube cave in on itself. You can even saturate the sand with a soap water solution to reduce the friction - which will result in a smoother, more uniform bend.
I used to work at a carbon plant. The kilns were made from hastalloy. Absolute pain to weld.
is this alloy similar to what's used in the kind of ovens used to make mu metal?
Or made from HASTELLOY, actually.

Hey Cody, you can fill the tube with table salt instead of tin, I did it myself and vouch for it.. I think much easier to do it that way, I learned it from someone who made copper coil for distilleries
Definitely worth a subscription - Nice work.

Oh man, I wanted to study for my exam but here I go watching your video
9:06 How to do this PERFECTLY: Use the hydrogen flame to boil the water in the kettle.
could you ellaborate? i still don't understand why cody can't supply the steam continously
@@user-df5is8jy6n Well; the flamable gas that is produced from the reaction, instead of just being burnt for the heck of it, could be used to keep the kettle heated instead of using the torch. So it would be a full circle production with "minimal" startup. The heated steam produces flammable gas from reaction with charcoal, said gas is used to keep the kettle heated, which then continues the reaction and so on :)
@@TheMols14 really, so it was for economic consideration? my hypothesis was, once the syngas produced from the reaction of steam and charcoal, the steam would only lower the overall temperature. i mean steam around a 100C, while syngas combustion would be higher than that i suppose. what do you think?
@@TheMols14 It wouldn't work without at least a little help from an external source, considering it dies down after some time. Would be interesting to see it done, though 🤔 Maybe it would balance out?
@@TheMols14 You could only use the exhaust to help heat it, not to heat by itself, otherwise that would be perpetual energy. The kettle is the fuel tank for the CO and H mixture which requires a heat source. Boiling the water, the reacting the charcoal, etc. takes energy away from the equation, meaning that the energy returned would be rapidly diminishing every time you went from steam to flame to steam again.
Never seen any video like this one clearly showing how to make activated carbon out of the industry and well, to prove it with a amazing test. Thannnnnnnnk you !
