Another great video. So useful for air and water purification.
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
@thallok Thanks for that. Really interesting.
How did you super heat the steam ?. I'm assuming with the electric coils inside?, Would it be any better to superheat the steam in that tube before it hits the charcoal?. Like that's a wrap that tube with a heater coil?
I thought about doing that but bending the tube was harder than expected.
@Cody'sLab I heard people fill the tubes with sand to keep the tube from collapsing and heard others freezing water inside the tube so its ice to keep it from collapsing when bending it.
“I might use this fine dust for something else.”
Yep. Forth of July is coming! 😂
now we just need a video on how to produce Sulfur from home.

@Jerry Whidby why would you need to house refugees in your home in order to be in favour of helping them? And what do open borders within the EU have to do with refugees? Are you concerned about a stream of refugees from the UK streaming into other EU countries in the wake of the Brexit disaster?
@Sozimajor its not deep
This is why lotr is superior. No virtue signaling. No creating a character for identity blocks to identify with. It's about the story.
"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.
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.

Lower tier YouTuber: Hey welcome guys to the charcoal challenge...
Good thought process.
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.
Holy crap, the first time I've seen anyone titrate anything since my High School chemistry class. So it wasn't just a cruel prank!
I HATED that shit Titration is the WORST

Cody, great videos... but take better care of your lungs... because you're constantly working with dust, you'll eventually get COPD without diligent use of a dust mask.
life is dust.

When he was pouring some chicken manure in to a compost bin I cringed at all the dust flying in his face.
You perform the most sketchy yet professional experiments
InXLsisDeo thats a strawman
Cyanide_Pill Gaming or he could be doing science because he knows his stuff. He even writes down and explains the process. This Does not make it less sketchy.
Retrograde Beats “sketchy yet professional” 🤔 I think that’s the best description of Cody’s Lab I have EVER heard!
What exactly was "sketchy" about this experiment?
@Delano Gaston For starters i would've used a ph indicator for the titration, being the most important step in measuring the results. At the very least he should have titrated each sample 3 times in order to get a statistical average even if he wouldn't calculate the error.
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.

yea the sparkling shiny dusts
"I accidentally made industrial grade activated carbon" :D
commercial
Dear Madam ,
I am Kailasanathan , a science enthusiast . Could you please explain. Awaiting your valuable reply.

@Gwynbade industrial is better than commercial.
@אε0 hes saying its not as good as industrial grade hes saying its commercial grade activated carbon.
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<x<50nm). 2) for your activating reactor design I suggest to use an horizontal pipe cylinder: you feed steam from one head and collected the outlet on the other side. In this way you have a more efficient contact between the carbon and the activating agent. 3) the increase in density is due to the ash to carbon ratio increasing with the slow oxidation of the carbon as you said. 4) I suggest if you want to perform next time also chemical activation: you can use ZnCl2 solution, H3PO4 or KOH. It is a little bit easier design you can make it in batches and at lower temperatures (about 500C for ZnCl2 700-750C for KOH). In the case of KOH be careful of reduced K metal! With that carbon you can make a lot of applications (not only depuration but als capacitors). Well done!
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.
@3:20 CODY: "this much charcoal wouldn't even fit in your stomach...".
INTERNET: "HOLD MY BEER!"
MORNING NEWS: "A crazy new challenge sweeping the internet, The charcoal challenge, where people try and ingest a kilo if charcoal".
ME: 🤔😢🤣😂
mostl compition eater ingest about7-9lbs of food or more so im guessing its possible, just not very tasty
Its gonna go into the Guiness book of world records if someone does this and doesent die of choking on charcoal
Florida man consumes large amounts of activated charcoal, sources say

7:04 fill with water, freeze, bend, defrost
Edit : after posting this, I keep feeling my grandfathers(old-school
blacksmith) hand hitting the back of my head ”don’t bend the
metal without heating, remember the devil takes one cold-forger every
year!” - so plz, if for more permanent solution, retemper after
defrosting ;)
Me: The One Who uses Titration for something useful in life will definitely earn my RESPECT
Cody: Hold Charcoal.
Cody has done some crazy unpleasant stuff for the channel, but a titration? Willingly? What a madman!
I never really had an issue with titrations, i find them quite relaxing if im honest
What’s titration?
Tit what? Have they started rationing them too? Oh.. it’s a sciencey word. Nevermind!
@Australian Gamer It's what he does in the video to measure how well the charcoal worked. Adding a chemical agent and measuring how much of it you had to add.
I always liked to do titrations. Photometry, however...
13:30 “Interesting”
Any twoset viewers here?
Hey Cody, could you make a video (if possible) on how to make a DIY mask to protect against viruses? Considering the shortage at the moment I thought it would be interesting. Thank you for your videos!
"I might use the dust for something else"
B O O M
I made my own charcoal once in a wood stove. I had a very hot fire going with a nice bed of glowing hot coals. I just simple pulled out the glowing red coals and dunked them in water. Then I dried them out next to the wood stove. I used it to BBQ it worked great I still have some left.
Damn I wish I was good at chemistry so I could really appreciate these videos.
We Need to have Science and Chemistry Teacher as good at Explaining Stuff as Cody.👍👍.Great Job.
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.
"would trip the breaker" - uhm - why? how low in terms of WATTs you can use per breaker and why not use two different circuits?
here in europe it's 230V x 16A per breaker = 3.6kW before you trip one - and you can split your load across 3 phases - a typical hot plate doesn't use that much, so when hooked up to a different breaker would had been easy to use both ...
Cody: touches mercury with bare hands, draws diagrams with gloves
I mean, have you ever tried washing marker off your hands? its annoying
Cody : has box of radioactive materials
Also Cody : butter is my kryptonite
@Jack Girdlestone Alcohol, even hand sanitizer will remove pen ink.
@David Galbraith
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.
15:23 Do I see "Controll"?

Great video! I love how you were able to use chemistry to prove the efficacy of your DIY batch of activated charcoal against a control group!
What brought me to this video was researching biochar and its difference from activated charcoal. It seems that activated charcoal requires higher temperatures, 900C; compared to biochar which only needs 300C of dry heat.
I am still curious where activated charcoal could be useful in the garden. I think if you just dumped a bunch into a garden your plants wouldn’t be able to access as much in terms of nutrients because they are all trapped by the adsorption of the pores in the carbon.
But biochar’s porosity would be much less and therefore could increase the cation exchange capacity without being too porous and adsorbing all the nutrition. It’s just a hypothesis but it sounds logical.
Maybe one could use activated charcoal to filter out microscopic toxins in the garden soil, making an inert soil that could then be fertilized.
To bend the tube faster fill it with sand it's really easier
I always get excited when i see your posts in my notifications.
I love these scientific channels.
When i start teaching, i plan on using your videos to assist with my lessons.
Lazy of me?
You bet.
But showing these high quality videos in conjunction with my lessons will keep the kids entertained
(with evil voice): "ACTIVATE THE.... CHARCOAL!"
I’ll remember this next time I get poisoned
love seeing an age old gen chem lab actually being used for real world testing. great work
Ohhh... So this is what my high school Chem teacher was trying to teach us...
Titration was it?
Something about getting salt from acid and alkali makes me think of pepper...
Yesssss! No more buying this stuff for my aquariums! Thanks!
Thanks for the kindergarten visual explanation for us plebeians
Makes me wonder about the details of clay now and medicinal clay since some still use similar to activate charcoal internally for chelation.
Honestly, I was hoping for some Minecraft explanation, lol :P
Then again—Clay -> ? -> Etho's Lab -> Minecraft?
@Bilb Ono Having the money doesn't make your smarter. You also look proud to "dominate" and imho that what make you appear dumb.
Science is a thing of collaboration and not domination.
Also in domination you can't allow someone to match you because that's not in your interest, slowing progress in the name of profit isn't that a dumb thing to do ?
@Foo bar chill guy, you're not a living test of human intelligence. I meant usa dominates the statistics, for. Example churning out qualified scientists and engineers. I never even said USA was the best, we just do not deserve this stereotype.
I also never said being poor makes you dumb. I said it's hard to do home work when there's police officers searching your house and other issues with the family structure. This may take a person who would have succeeded in life and brand them with bad grades impairing them later in life. I'm not saying you cannot over come adversity but this is a big problem in a lot of USA cities.
@jafinch78 That's just plastic. It burnt off during the heating process. If you think pouches are any better, you might want to think again; they'll be lined with plastic too, or be comprised entirely of plastic.
The plastic liner is there to protect the food, and subsequently the consumer, from the metal.
This guy makes me want to do chemistry... then I remember how dumb I am, and resolve to stick to gardening.
16:47 how does this not affect the amount of iodine in the solution.
My guess is is does but only very slightly ?
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!
Does the reaction realy take energy, or is the relatively cool stream cooling down the furnace? If the reaction does take energy, I imagine both are true.
Edit: never mind. He says it is endothermic.
3:15 "Accidentally ingest a poison..."
OH BOY! A crazy video coming soon!
@bonjourmssr nope! We will try to save your tookus!
Every substance is a poison, don't forget that.
"I ingest a lethal dose of cyanide then save myself with charcoal". lol. If he doesn't upload again for a while we know why.
I watched this video 15 minutes after I accidentally ingested a bit of sodium percarbonate...
drinks a lot of activated charcol then pukes it out
I guess when Cody has an accident and gets poisoned with mercury he can take his own activated charcoal to detoxify.
I just dont like this video because it include titration 😂😂
