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...

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

Wow I am your 5th subscriber! When you get big remember me!!
Awesome tip from someone with domain knowledge - thanks!
Thank you.
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. :)

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.
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.
You perform the most sketchy yet professional experiments
So true, especially anything with mercury...

This is amazing Cody, you’re much appreciated for sharing this project
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.

"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.

Commercial labs use it a lot, to the point of having machines that do it automatically.

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.
Loved your science this episode cody. Did a great job of presenting your results!
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.

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?

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
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)

It's not clear if it's actually better, due to limited accuracy of measurement of weights and volumes. He said that in the video, mentioning error bars.

Extra nice work
that tube bending needed more video man
Keepem coming Cody. great content!!!!!!
Great info, thanks for your hard work and thorough assessment.
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.
@@theCodyReeder 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.
For tube bending we were taught to use quartz sand. I think because ordinary sand might burn inside the tube if heated
@@ChristopherJones16 Water is used for bending tubing for instruments and pipes.
What if an iron tube is filled with very fine inert powder, an induction heater is used, and normal steam is passed into the apparatus? It could be bent into an u-shape to facilitate that.
Would that be able to superheat the steam?
If we want to just increase the surface area, how is this activated charcoal better than just grinding it up to a very fine dust?
get it fine enough to be the equivalent of activated and it becomes useless as a filter because you cant hold onto it.
Cody'sLab could it work where you didn’t use it as a filter? Like if you swallowed a poison, or is activated still better?
@@superalvin7208 good question!
it might get too small and your body will absorb it along with the poison, making it useless.
fine dust wouldn't get channels to allow sht you need to react to go through.
it will act like a surface of one brick.
for swallowing it should be not effective too
because you need the pieces to stay and work in your stomach for a longer time.
As always a great and complete video. Keep up the good work

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
