Cody looks 10 years younger using one trick
It’s mercury. The trick is mercury
Mercury pills were thought to lead to eternal life.
So the secret for the philosopher stone was in mercury not lead.

Little clark kent vibes :D
Dead Chinese emperors hate him!!
A+ for being a true scientist by admitting a flaw in the experiment and evaluating, constraining, and delaying possible conclusions until that flaw can be rectified.
A++ for thoroughness. Starting over after realizing flaws in a process that takes 6 months to draw a conclusion would be maddening to most. Cody’s dedication to the scientific process, work ethic, and overall patience is to be commended.
Come on people, we all know he is a time traveler trying to bring are dieing earth back to life. Or is he trying to show us how Mars was made livable lol. The world will never know.
I had the exact same thought but you definitely said it better than I could have.
Never would have thought of the quality of the water source until he brought it up
Can't wait to see "the grass was random eaten by a cat during the experiment" in the Materials and Methods. Still A+ though
"The cat decided to give the experiment a taste test"
Yep, definitely Cody's cat!
Underrated comment of the year
@@TheDanielsweden indeed
he's learning from the best
Was expecting "the cat decided to...Fertilize the grass"
:P
Damn Cody, you manage to make things like "watching the grass grow" more interesting than 90% of whole TH-cam...
you have swerved the cannabis growing channels...its not chlorine, its nutrient retention, larger char particles will retain more nutrients- i suspect thats what hes seeing.
@@deadprivacy stf
If you haven't already, you should grow some grass this way, it's actually pretty fun. I don't mean experimenting with anything, just grow it. Make a time lapse or something, it's fun
@@reviver-death 😂
Holy scientific process, Cody! Lesser youtubers would've looked at the grass length and simply declared "it does", but he took the opportunity to try and debunk his own hypothesis. Deep respect for this man.
And to commit to potentially proving that size really doesn't matter! Unless you're talking about statistical sample sizes...
This is, contrary to what others claim, science at home. Of course, you could do it with larger sample sizes. But the whole process like planning, data collection, analysis, interpretation and drawing conclusions for the next experiment is just superb :) A great video even for a guy like me that has nothing to do with gardening or agriculture!
That's what I call science!
And not "trust the science"
Cody is the kind of guy who can make watching grass grow legitimately interesting.
What a soft-spoken mad lad.
have you seen his snow melting video? i'm still waiting for his paint drying video
I didn't even think of that, this is quite literally a 12 minute video about grass growing XD and yet it is indeed interesting
Cody: "I'm growing grass in my house"
police: "He's doing what!"
The only person who has grow lights for growing literal grass
That's the least suspicious thing he's ever done. They'd be relieved.
Lllllllegal
@@AtypicalADultHooD But to be fair, the nitroglicerin and yellowcake videos were great XD
"You know, just a pot or two"
Police: "POT?!"
"Yeah, my maid Mary Juana is looking after it while I'm gone"
Buddy in the middle of the night whispers into a sleeping Cody’s ear: Mor grass gud.
Buddy rigged the results by depositing chlorine in the water
He's such a great sidekick

As a Botanist (final year PhD) I think you've done an amazing sound experiment here and you've outlined how to improve it/what went wrong. Science rarely goes how you want it to. Fantastic job Cody!
As a plant biotechnologist, I totally agree :)
For a no native english speaker
What means "sound experiment" ?
Like in my mind it is just something about sound but u mention u are a botanist which well confuse me why it is a "sound experiment" :
@@7410Alucard A sound experiment is an experiment with strong (very good or robust) experimental design. Hope that is clear.
@@steviekehoe Absolutely :3
Thanks for explaining it :D
Learned something new ^^
The cat's like: I happen to be an expert at putting lumps in sand. :)
I never thought I'd be hyped for grass growing in carbon sponge-enhanced dirt, but here I am looking forward to to it
Shocked to see Cody without a beard.....Immediately went back to see if I missed any prior videos.
I thought the same and then I realised Cody has new glasses. They look awesome on you dude!!
On his second channel he has a video of him shaving it from a few months ago
He got a date...
Now i know why he looked this different...
Maybe the next video will be about the affect of particle size on beard growth
"the cat supervised the whole process" and my cat was fascinated by your supervisor :D
ok but why is beardless cody so handsome can someone explain
Beardless Cody always rushes Venetian Arsenal thats why
The trick is him eating charcoal.
What a coincidence seeing you here, good Sir! Off to watch some civ 6 next I suppose ;)
I thought it was Commander Data.
I think he's generally handsome.. long hair, short hair... he radiates gentle brilliance, which is an attractive quality that enhances any physical features.
Experiment is great. Filling in the gaps where others haven't. I also like the black background, it is very clean and not distracting while you're giving your explanation.
Can pretend he is back in the cave

Everyone during a pandemic: grows long hair, a scruffy beard, showers once a week, eats junk-food daily, exercises never.
Cody during a pandemic: smoother than ever.
Same guy grabbed clay (or something like that) with gloves and cut to a scene of him grabbing cow dong barehanded lol
Way ahead of you I did all that before the pandemic. I don't need a bunch of bureaucrats to tell me how to live right, LOL.
i agree with all that except the junkfood. You gotta get that from outside.
I cook at home everyday man, what else am I supposed to eat? xD
You are very clever to have realized the chlorine exposure. That is a very small piece of the puzzle but had an apparently massive impact. Nice one Cody!
Someone: “...It’s like watching grass grow...”
Cody: watching grass grow...hmmmm

Buddy: *slaps roof of soil containers* "These bad boys can fit so many turds in them."
Yup.
Best supervisor ever.
I love your dedication to doing science correctly and showing people that science is messy and is often worked on and fine tuned over time.
People weren't just making up the laws of nature, we stand on the backs of giants.
Speaking as a North-ish European.... your "soil" looks a hell of a lot like "sand" to us.
That's the desert for ya!

Cody is trying to answer the age-old question...
"Does size matter?"
I would have given you a like but you already had 69 which was perfect...
I've always appreciated how Cody doesn't care about the duration of his experiments but, rather yielding accurate results.
Cody: "I've been obsessed with (eating) charcoal for some time now" - fixed it for you
He is creating a new kind of charcoal food now.
Cody is becoming TH-cam's dad and I'm so proud of him
Very interesting ! Looking forward for an update
Try using rainwater. During winter, melt snow. Makes sense because when you put the charcoal in the ground, that will be the water source, and the bacteria will be used to it.
True but by using distilled water that eliminates any data changing factors that comes with what water you use and your results won't be affected by it. The chemicals in rain water can vary greatly between different samples.
How was this comment posted 22 hours ago when the video is 20 minute old?
@@jholotanbest2688 patrons?
Huh, interesting point. I was thinking distilled water might be a good idea, but I don't know how hospitable that is to bacteria. Maybe that is another experiment: tap vs rain vs distilled vs filtered tap vs filtered rain vs filtered distilled. (Filtered distilled as a control against the filter causing issues). Also the potential variable of letting the water sit to give the chlorine time to react away first, after which the tap would still have significant amounts of other additives such as fluoride. So much sciencing that can be done!
@@yomanxy So the patrons have access to the same youtube video somehow. Or is the same video just unlisted.
This is the kind of cool stuff I enjoy seeing get documented

@@bignig123 eww a bigot

@@olbluelips nah its a problem
separate your char into different sizes, then "activate" it with either, wormcast or seaweed extract or the many other options. also have one/s with "inactivate" char too, see how they fair.
That's a good idea
Also add different types of fungi, fungi is what really activates the charcoal as a single gram of charcoal has about 1000 square meters of surface area.
A full kilometer of fungi covered surface will allow the plants to get every shingle nutrient they need with the help of a super large fungi highway network.
I wonder what different fungi do
@@BigBodyBiggolo That was my theory but I saw a video the other day saying the very limited research done on it suggests otherwise. He put the biochar and the fungi in different layers. I'm wondering if it isn't because the fungi likes an acidic environment and biochar is alkaline. Fungi does like a lot of carbon however.
@@BlackbirdArtandDesign yeah you have to charge the charcoal with compost teas and other slightly acidic nutrient rich brews to supercharge the charcoal with nutrients, then you can add the fungi cause the charcoal is now normal pH or slightly acidic preferably around 6
Charcoal in aquarium filters concentrate nitrogen and bacteria, I always used it to make a layer in pots to every plant I wanted to grow up to the stage to plant into the definitive place. Some species of plants profited a lot from this, mostly those that are found in wetlands. By the way, this was my goal, finding ways to regrow wetlands to obtain clean water sources in damaged landscapes. Nitrogen is key, grass roots create the filtering and infiltration system to wet the soil. Some grasses are incredible efficient in doing this, the roots reach several feet under the ground. There are experiments that show this, creating wetlands on very low precipitation regions. Charcoal may help with this, mostly by retaining water by its porosity, and offering a moist environment for some bacteria and other organisms.
Alternative title:
Experiment to determine if size does matter after all
Wow, an experiment on TH-cam that includes a "threats to validity" section! This is a great science video, probably even better than if you hadn't used the chlorinated water.
nah, now its a warning for every future experiment for both him and his subs
I love two things in life: novel scientific experiments that add knowledge to the world, and safe, happy, comfortable cats.
CODY! I was on Snapchat watching “what if” and they’re doing a special on dry ice and you were on it! In the clip you did chewing on dry ice! It was crazy! I just had to make it known to the world :)
You also may have washed away nutrients that was stuck to the charcoal
That is what I thought too, that graph should either be flat or going in the opposite direction. But there was a slight peak at 4, maybe that's the optimal size.
@@ArtesianFalma I would have been quite suspicious of a perfectly declining graph. Growing grass should have some unpredictability in it, so let's wait for the replicate! :)
Cody's age ranges wildly between videos--he obviously has invented time travel.
He kind of looks like my brother. My brother looks old with a beard and at least 5 years younger when he shaves.
Root aeration might play a role too. When I pot my plants I make sure to keep the particle size high so that the roots can breathe and the water drains through quickly. Thanks for the great video Cody!
Let's take a moment to appreciate the fact that in the last 6-7 years the quirkiness and formula of cody's video hasn't changed .
We're closing in on the end of the cursed year that was 2020 and the only thing that has changed over time was the quality of the videos which progressively improved throughout the years.
I'm not american so I don't celebrate thanksgiving and I might be a little late but I think I speak for everyone when I say that we're grateful for your channel cody , we truly do appreciate everything you do around here.
Hey Cody, I've been assisting a professor of mine who specializes in freshwater systems. It might be good to set up a filter system that makes Deionized water, this type of filter takes out minerals in the water including chlorine. In lab we -are- were (thanks covid) we would use deionized water to test for tannin concentrations leached from different leave species, any chemical interference in tap water could have an effect on our readings. Deionized water is expensive to purchase but deionizeation filters can be built and I have no doubt that you would be able to build one.
Another suggestion that I have is that you may need test multiple plant types, if you only use one species of plant you may only be getting data on what biochar size is best for that species. I know you said that you were going to do that but I just wanted to encourage you to test with multiple species. You may want to select plant species with varying root structures or nutrient requirements.
It made me so happy to see this video and how well you showed the scientific method, I look forward to future videos on this and other topics.
@blue Deionized water removes ions from the water. Ions classify minerals with charges, so a filter that produces deionized water will remove dissolved minerals within the water such as chlorine which was the main reason I thought this filtration system would be useful.
Distillation is also a very good method to use and I honestly didn't think of it at the time, I was very focused on removal of just the dissolved minerals. If you want to remove dissolved minerals, organic matter, and various chemicals distillation is used. Deionizing the water will only remove dissolved minerals and not organic matter which I thought would be something that Cody may want to keep. While distilled water is more pure it takes a long time to make, deionized water is quick to make and doesn't require the same amount of energy that distillation does.
Thank you for asking me this, I was really happy when I saw this reply.
Buddy is Science Cat. This I declare.
Great example of how variables you'd never think about could play a big difference in your results
I really like that I can always trust Cody's content to be good science and never any bullcrap click bait,thank you Cody for being real
Like the newly-groomed look, but would rather have had Buddy present it, as implied by the thumbnail! When you get bored with doing this with grass, try catnip!
Perhaps the trend for particle size could be related to how much stored GoodPlantStuff™ stays within the pieces after being washed, not necessarily just the chlorination
Exactly what I expected when I saw him washing charcoal
Actually, the charcoal has an unbelievable amount of surface area and little nooks and crannies. It would be nearly impossible to rinse off the GoodPlantStuff.
I'm tired and I read this as "the effects of bipolar disorder on plant growth"
I love this topic! As a gardener I use biochar in my garden all the time and charge it with compost tea.
Is it chlorine related or that you washed out more nutrients with water? Also maybe the finer particles wash out the good stuff easier than bigger chunks?
My thoughts too!
More nutrients are not necessarily important if the plant has excess; as Cody was fertilizing the potent difference is likely down to water retention if I had to guess.
Generally high carbon source organics (something broken down by bacteria) will "release" more nutrients as it decays. Also while I don't know for sure I'd wager that the biochar has a high cat-ion capacity thus much of the nutrients that would wash away were retained.
I'd guess that kind of wash takes time. Just by experiencing with dialysis I would guess that.
Learned a while ago on a commercial ice machine, tap water+charcoal filter=stuff growing in the ice bin.
When I was in college I did research in the plant biology department on the effect of different size carbon fullerene particles on the growth of tomato plants, specifically their effect on the uptake and respiration of water. It was super interesting and this project reminds me of that!!
The thumbnail poses the question "which bucket is the closest grey to my cat?"
Your new glasses look good!
Only Cody is willing to spend his time _watching_ _the_ _grass_ _grow_ for science!
I love these kinds of experiments involving plants and soil!
I don´t usually comment a lot but i gotta say this :
Even if it´s just seeing you grow some plain old grass i can not help but genuinely enjoy your videos.
Thanks for doing what you do, i wish you all the best!
Greetings from Germany
I expected to see a timelapse of grass growing at the end but instead saw the bobcat enjoying grass. not really disappointed.
Watering plants with rain water vs tap water would be an interesting experiment
I love videos like this because it helps you with your projects but also has a greater use for even average people like myself. I only have a little veggie garden in my yard but knowing what size bio char could be really helpful if I wanted to really get serious about it.
I'm glad you kept the project going, even after kitty helped mow the grass!
buddy: hey this black stuff smells kinda like fish, can i eat it?
If it smells of fish and tastes of chicken ........ ;0)
@@totherarf ... then it needs a shower. Gross.
K, so. Who are you and where's Cody?
Jk man, you look healthier in this video than over that past year or so. Healthy Cody is Happy Cody!
Publishing results of an experiment that hasn't gone as planned together with an honest commentary is a habit that should be more widely spread. This video was very interesting. :) Good luck with the project!
I think cultivating the bacteria from the biochar onto an agar dish for studying and describing them would be pretty cool.
Damn dude, a shave and a haircut* and you look like a respectable gentleman! 😄
(*2 bits)
Looking for that D huh?
Ah yes, I needed some of Cody’s lab today
The best experiments produce results you don't expect. You learned so much.
Cody, I don't know if my comments finally reached you, but I am seeing big improvements in production quality, which is awesome. Please don't stop working on it. There is still work to be done but at this pace you could be onto something big. Love the science, cheers.
The way you explained this video seemed like you were ready a scholarly article. You should publish.
He honestly could, if he had more replicates and did an ANOVA with some type of regression to analyze the effects of his treatments/manipulated variables on *dry* grass weight. If he can do all that, he could kill it in grad school... Just sayin'
as with any good experiment it needs to be secured against interference from the cat. great video!
Cody, grow your goatee back man, 2021 calls for it!
U r the best TH-camr u make me more interested in science than bill nye
I am extremely interested in how you plan to produce and distribute such a vast quantity of charcoal. sounds awesome!
Hi ya Cody, you should have weighed with full roots too. Root production is more important as well at that point in it's life. Start using RO water as well.
Oh yeah, I didn't even think of that.
I've read studies about root to shoot mass growth depending on nutrient availability and other stress factors. I'd push the point that all mass should be weighed (dry mass) to help rule out those factors.
TIP: next time, thoroughly dry the grass clippings out before you weigh them, so that you can eliminate the variations in water weight and ensure that you are measuring pure biomass! LOVE the videos!!! Been watching for a couple years now, its always kept my interest!
Thank you for this video! I have been wondering the same thing for a long time. I appreciate that you took the time to do this, very well done. Thanks again!
Cody plans to bury several tons of charcoal on his land.
Future archeologists will be so pumped when they find the site of CHB and can perfectly carbon date Cody's life.
sadly carbon dating is going to be messed up for millennia to come because of all the nukes we tested.
@blue Anywhere on the planet, sadly. But that shouldn't affect carbon dating as much as say, a geomagnetic storm or similar event.
@@c.a.mcdivitt9722 While carbon dating is kind of fcuked we only use it for pre-historic dating because it is pre-historic. It does come in handy after but we document almost everything at this point so in the future carbon dating will not be as necessary.
@@carbon5362 Convenient timing to stop... or decay rates are variable and carbon dating assumes there haven't been large events that influence that in the past!
@blue Trade winds.
Soil level in the containers will effect how much of the grass gets cut. Larger particals could make the soil level higher.
Good point! The soil being added to the bio char should be weighed before mixing!
@@alvagoldbook2 weight and volume are 2 different things.
He said and shown in the video he measured the amount of dirt with a cup. Not a very bulletproof method, to be honest.
Seems to me by the footage that the soil levels are different for each cup.
@@cutebunny6690 it probably doesn't matter much, but it would be nice to eliminate as many variables as possible. soil doesn't uniformly compact, which I think is why the soil should be weighed before mixing.
True, however the results were taken after the grass had already been cut down to equal (known) heights, so the samples were taken from the same height position across all the pots, regardless of the initial grass length and post dirt height
@@SuperRandykidthat's true, but any additional leaf length means more surface area for photosynthesis to occur thus giving the lower soil level samples an advantage.
Thank you for all the effort you but into your experiments :) Can't wait for the update!!!
This is your best video in a while, I love experiments!! Great work :)
This video was full of information I didn't know I needed to know. Thank you for teaching me something oddly fascinating!
first thing i thought when he washed the charcoal: "noooooo! thats tapwater, it has chlorine!" :)
Yep, same here. He went from saying he had to keep it wet to preserve the bacteria, then hit it with chlorinated city water. SMH
Well I'm happy I live in Germany where - like in most of Europe - you don't have Chlorine in water. When I think of chlorinated water, I think of 3rd world countries.
@@whuzzzup uh, i fear you are wrong. In all European countries chlorine is still in tapwater. It is still the main disinfectant. Also in Germany. It's perfectly fine for human consumption, as the quantities are extremely low, but they would still be harmfull for the bacteria Cody needed in the charcoal.
@@thsaintful Nope. There is usually no added chlorine in German tapwater. It can be added in cases when needed, but it's usually temporary and will make news. In my region the chlorine in the water is below the detection threshold according to the latest report.
Same in the Netherlands. Our water is perfectly safe without the use of chlorine.
Well done, thank you for taking your time to do what you do so that we can enjoy content such as this!!
i appreciate getting to see your thought process and planning for the next experiment. thanks for sharing that in the video as well. best part of your vids .
Have you thought of either presenting the data/info to a professor or someone else in a relevant field of study or formally writing up all this stuff you've found with charcoal / biochar and trying to publish it?
"the cat really likes grass" yea no kidding, very odd that he likes it so much.

Only Cody can make watching grass grow interesting
... I literally just watched a video of grass growing. Congrats, Cody. You've ruined me. XD
Thought! Take some of your biochar and do bacterial growth tests on exposed to city water vs not.
As people with aquariums can tell you, if you use city water, it kills bacteria. That's why it must be dechlorinated before putting in a tank. And if you rinse your filter, you have to use water from the aquarium as the city water will kill your beneficial bacterial colonies that are used to keep ammonia, nitrate, and nitrite levels in check.
Probably the most multifaceted person ever regarding doing so many different things in science experiments
Awesome video man! It’s great so see how experimentation works!
When spreading biochar over a large area, say a hay field, does it matter how deep you till it in? Can you get away with not tilling by spreading it on the surface followed by a layer of mulch/green manure?
I'd say it depends how deep the roots go. Usually you say 30 cm is the plough depth/root layer for crops.
Cody you should look into how mycelium interacts with plant roots, and do an experiment recording how plants in inoculated soil grow compared to plants without the mycorrhiza connection
Love the new video style. Very professional. Great scientific experimentation!
I LOVE IT WHEN YOU UPLOAD MY DAY LITERALLY GETS BETTER!
Thx, after this I'd be more interested in soil to coal ratio, figure coal-size might be negiable after the clorine issue is resolved
Also a good point for investigation!
You also need to check moisture content when you weigh the grass at the end since that varying could skew the numbers a lot.
they all recieved the same amount of water, so any varying in moisture can really be chalked up to difference in growing, which is what was being measured
Weak grass can’t hold it’s water (said like a bar elf)
Cody’sLab is the real life Etho’sLab
what an upgrade this channel has done over the years.. love this stuff cody big thanks for your insight
