I love bonus experiments!
Crazy!!!
I would love to see a collaboration or a Bobby Duke's Lab video lol
@@jonduffin7560 me too
Lol wow 🤯
Cody: "I extracted iodine from salt!"
Me: "I extracted salt from the box..."
Burn 16 you tactical scientific bastard.
After I extracted the sodium chloride-potassium iodide mixture from its container, I decided to apply about 8 grams of it onto my food.
Hahahaha lol
@@KrazyKyle-ij9vb Oh dear, 8 grams? One word dude. "Health".
But the biggest challenge is extracting the last bit of toothpaste from the tube
1:30 "This is kinda like math"
Does that mean Cody's going to wear gloves to do this?
Cody, the type of guy to challenge himself.😂👌
i also saw that hahaha XD
He did not challenge himself, its a guy who calls himseld Cody’s Blab
Nero Cagliostro it's his 2nd channel
It must be all the mercury.
Internet Guy or maybe lead
*sodium chloride*
It's salt Jimmy
*that's what I said. sodium chloride*
c-codium sh-shloride?
Gewel. "Um brooo, it's called salt." Nice meme reference
Fun fact: Silver iodide seen on this video is also salt.
AlfonsoB yeah it tastes way better
the chaotic neural science education this world desperately needs
I challenge you to extract mercury from the solar system
*tips fedora* Yup. 😎😎😎
Calls darth Vader
Uranium from twizzlers
And uranium and neptunium and plutonium
his mercury is in the solar system so he has done that many times
I have chemistry class and my teacher thinks I'm some sort of genius because I know a lot of the stuff already but it's just because I watch you lol
Ultimate Finesse same, CZcams is my text book for everything
plus, youre a genius :)
I don’t have chemistry yet (but I’m exited!) and in science when we’re gonna learn something that I know about I am like YESSSS then I get bored during the lesson since I know everything ;-;
@Heads Mess Shows a very poor teaching attitude. Should have helped you excel and bring your fellow student up to speed instead of berating you.
@Heads Mess
With all that, what are you up to these days? Did you go into higher education or had you had enough of it by the end of school days? I came to very similar conclusions as you and early enough I realised the 'education system' held nothing of great interest or worth for me. Not boasting, that's just the way it is/was.
I don't mean to sound patronising in the following, I assure you I am not being, but it is sometimes difficult to put my proper inflection into text.
I absolutely agree with you on the fucked up education system, but that doesn't excuse her or any 'teacher' to just 'follow the curriculum'. It shows a complete lack of real individuality.
Believe me I do know what the 'education system' is, my history and experience of it parallels yours.
Your metalwork teacher sounds like a typical arsehole-teacher (in later years my sister and her colleagues were/are the same), 'blinkered' and in it mainly for the money-benefits and the 'ego-massage' that the title gives them; but totally out of their actual depth re the basics of the subjects/tools or actually engaging with the pupils and teaching any of it. Not all of them fit that mold I had several incredibly good 'teachers', but they were the very minor exception not the greater norm.
I agree on the 'babysitting' too, but that is a fault of the so-called education system and the inordinate number of 'pretend teachers' that are either not really on top of their subject or are too scared of critisism from the 'authority-system' or just plain unable to communicate properly.
'She' could have better engaged you and the kids by using the spare time you had created by going through your methods and other different methods of getting the right result/answers themselves, in the meantime introducing the fundamentals behind it/them and the applied techniques. She missed an opportunity there to elevate and educate. Everybody is at different levels and abilities when at the same biological age, experience and other factors will change that for the better or worse. The 'bright/knowledgeable' ones will be bored/wasted in the 'by rote' curriculum, the lesser able/knowledgeable will be failed on many levels.
I never said being a teacher was easy, but if they can't/wont rise to the challenge then they are not worthy of the title or post, they are just facades for babysitters and time wasters, that's their time and others.
It was good that you had the drive/abilities to do 'non-curriculum' projects, most people do not have that in any form, the vast majority are waiting for 'something' to be provided that never materialises or trained from birth to just 'do as told' and actively discouraged from even contemplating anything other; being superficially entertained and distracted and kept-busy is the best they will ever get.
I sense an anger and disappointment in you at the failure of the education system to help you progress and achieve more.
I would like to contribute more but I am not in any position to do much other than confirm your conclusions and encourage you to keep swinging at it; you might be in a 'minority' but that doesn't mean you are not worthy of much greater achievements.
I teach people/kids, either on demand or by happenstance; usually I can sort out the problem in a few minutes, by going back to real basics. The response is nearly always, "Where the hell were you when I was a school?!" or "Why don't they tell us that at school?!" There is no room for bullshit in my world, if I know something about a subject I make sure I REALLY know it from as many angles a possible, and I will put great effort in to truly empathise with the 'pupil' and convey that understanding both in technical/fundamental detail and in practical use. As others have said, "If you cannot convey and explain something well in easily understood detail, then you don't really understand it". I will throw out any long held beliefs for something that either better replaces it or clarifies a deeper understanding of it. It is THE tenet I live by. I might fail occasionally, but by God it'll know its been in a proper fight if I take it on. And I'm always up for a re-match.
Good luck in your future endeavors. It is unlikely that any will praise you much even if you rise above the masses or achieve your enlightenment and potential, most wont appreciate it even if you do, you will just have to do whatever it is you do for your own satisfaction. I think if the world you are in doesn't throw you a challenge worthy of your efforts and abilities, find another or construct a goal of your own.
That's life.
For what its worth, I wish you well.
You didn’t die from drinking dihydrogen monoxide, lucky!
SkeleBonePancake yeah why would he?
well not yet at least.
damn you, beat me to it. now I have to like yours.
Cody'sLab video demonized?
I heard that it normally takes 80 years to die from it, but one thing is for certain: 100% of the people who have come in contact with it have died.
Can you try and extract Mercury from fish?
iu6 might be interesting if you really think about it
deconstruct a fish to all the elements)
he needs a big predator fish if he wants to get a noticeable amount..
iu6 you tube is really gonna kick him out lol can’t show the people the dangers lol
He's talked about possibly doing it, but he said it would be near impossible with how little mercury is in tuna.
"When all is said & done, Cody still has all ten fingers, and both eyes, so we're calling this experiment a success. Stay tuned next week, when Cody wilI be volunteering to serve as a test pilot for the new Kerbal Re-entry Vehicle's Geobraking Test Program!"
As an aspiring chemist, I really like when you put the reaction up onscreen. Helps to understand what's actually happening at the molecular level.
In german the stirbar is called "Rührfisch" which literally translated means stir-fish
The stir bar for my coffee is called a swizzle stick, named after Bermuda's national drink the Rum swizzle.
What do they call a quarter pounder with cheese in Germany?
rubikschu Royale mit Käse
EINE KWARTZE KILO WIZ KEEEEEZAAAAH!
Cody, you do a lot of awesome chemistry but it would be great if you would overlay your videos with the chemical equation of each step. It would really help understand exactly what each step is doing. keep up the great work!
I say the reactions, is that not enough?
Cody'sLab no
@@theCodyReeder Sorry about the length of this, but.
re Scott Dangers request: Your answer/tag-question to him is reason enough for you to suspect that it is not enough.
No, its not enough. For all the wonderful and interesting content you provide, the problem seems to be you are so adept and comfortable with the equations (and in that you are not the norm). Your adeptness blinds you to the fact that most of your viewers are probably not adept at all with equations, regardless of the level of their own practicality.
Although sometimes its enough, to say the equation not everybody gets it just from the equation alone due to unfamiliarity with 'equations'.
You seem to forget that for most people the 'equation' may as well be Greek; partly this is due to poor education, and sometimes it is the difficulty of 'seeing' what is happening in the equation. It is akin to dyslexia, in that looking at an equation and 'translating' it into what it means in real terms often it just come across as viewing a lot of impenetrable jargon if the viewer has not been properly introduced to the fundamentals. 'Officially' at least 10% of the populace has some form of 'dyslexic' issue.
I had similar trouble with the 'algebra' of maths equations, until someone (a college technician) eventually did a proper line by line breakdown, instead of the previous and usual 'do it yourself' dismissive attitude; then it was like a light-bulb turning on and I could see the steps that previously it was assumed I knew how to do but could not up to that point make the mental jump. It only took him 10-15 minutes but I learned more then than in 20-years of maths 'formal education'. I still have to 're-invent the wheel' at times. As I go through it step-by-step, I often hear pupils say, 'Why doesn't/didn't anyone else tell us that? Now I get it!' As a dyslexic it will never become second nature to me but I can at least fight it to a standstill now that I know the idea behind it. It might seem trivial to you when you know how the trick is done and it becomes virtually sub-conscious to you, but please don't forget to at least occasionally do a complete breakdown of steps and why each step works the way it does. You are unintentionally alienating a lot of people by not including these things. I teach practical electronics and I still sometimes forget that even the simplest of schematic means nothing to the pupils unless I explain it and each symbol in it in practical terms of flow/charge/resistance etc; otherwise to them it is just hieroglyphics. (And by 'pupils' I do not just mean school kids, I have several pupils who are retirees). Anyway please keep up the good work, I enjoy the posts and appreciate them immensely, I have learned so much from your experiments and am inspired by your attitude. Thanks very much.
Finally I re-iterate; no, its not enough, the background is essential. Its not meant as an insult, its well meant feedback. thanks.
@@paulforster6229 Why should he have to put in all that extra effort for videos which are essentially for entertainment? He doesn't claim to be educating to any standard that would require us to know the equations. Just saying what he is doing and what effect this has is enough for a simple youtube video. If you want to know the equations and anything else that the average viewer doesn't care about, search it up on google or read a book. He's not making videos to help us pass a goddamn chemistry exam.
@@Meatrubexe He doesn't need to, but it was implied in Scott's earlier comment that it would be appreciated if he put them in sometimes, and/or even the odd in depth work-through; as long as its not information that would get him demonetised, why not? Not everybody is conversant or familiar with all the underlying principles. Entertainment is one thing, but it doesn't harm to elevate peoples understanding at the same time, in fact it would probably help appreciate what he is doing even more. I love Cody's Lab, but sometimes he jumps to something and I have difficulty following the reasoning.
Chill.
I'm so happy you're getting new equipment! Loving the glassware. Making sure to watch all your vids!
I was worried for your experiment when you were distilling off low grade acetone and looking for a white powder. I've rotovapped reagent grade or higher acetone and had residues from impurities in the acetone during processing. I glad it worked overall though.
Cody is so wholesome it just makes me smile. Thanks for teaching me more than my science teachers ever did!
I love that you challenged yourself, pure genius.
-I don't see anything happening there
*Takes a torch and blasts it to kingdom come*
That's certainly one way to quicker results :P
I love the part at 7:20 when you get excited about the precipitate forming. It’s such a heartwarming moment that shows your genuine appreciation of chemistry.
Cody, your channel is absoloutely amazing. You really need more subs, i love your amazing content and awesome acience experiments
That siver iodide that you made is also used for weather control. Clouds get doped with it and that makes the rain fall earlier and more heavily
You are probably my favorite CZcams creator, not only because your videos are interesting, but because you are so consistent and prolific with your content. I respect that
Haha your new profile picture is adorable 😁
howdy partner *cowboy noises*
Digital Pyro that’s what I thought
Agreeded
One of his first couple pictures was this, he changed it to him upside-down after he started becoming more popular. It's also how he got enough cow poop to pee on to make gunpowder, I miss those videos.
"It's also how he got enough cow poop to pee on to make gunpowder, I miss those videos."
Hold up what
I challenge thee to extract pure Potassium metal from Bananas.
That shit is explosive
Does that mean *Minions* are explosive?
The potassium in bananas are ions so can not be attracted
Extracted*
@@Corkodile Ions can be reduced to obtain the actual element...
am i the only one who watches these videos but has no idea how the chemistry works? I find it so fascinating but i literally have no idea of the science behind it lol
same here
I mostly sit here thinking "Oh that's cool. Chemistry is awesome."
You might want to look into stoichiometry, it shows the relationships between the relative quantities of periodic elements in a chemical reaction.
I am something like that. I /used/ to know what he's talking about, but I passed chemistry and never used it again.
@@minichirops I have been taking chemistry classes in college but it has been a couple of years since my high school chemistry class, if you are going to be majoring in metallurgical engineering I definitely advise studying chemistry on your own time to avoid forgetting useful information.
@Chris Russell don't forget extractive metallurgy.
This is a really nice demonstration of the use of preferential solubility. Thanks Cody!
Thank you for being on CZcams, Cody. You are an inspiration for many people.
When you're reusing solvent like that, a soxhlet extractor really would be more effective. I got a 500ml one for like $20 on ebay and its pretty good.
TheIdeanator I was going to suggest a soxhlet also; though it may not work too well for extraction from fine powders.
stamasd True, that's what a good frit or cellulose thimble would help with. You wouldn't necessarily omit the filtration step which should help with any residual solids.
the mailman would break it, for sure.
Robert Heal they didn't break mine.
@@stamasd8500 that's what glass wool and/or extraction thimbles are for.
This gye is pure genius .
Aquagiri he was just attending chemistry class and actually listened to the teacher. Once you get the basics it's pretty simple stuff. But, and that's the amazing part, he has a talent to explain all the stuff without getting to much into the boring stuff.
Marc Quadt it's not very simple. I'd say it's quite difficult to grasp in a school curriculum especially if you have few chemistry classes and mediocre teachers (my first chemistry teacher was awesome, but the second one was quite bad)
Aquagiri i bet he stayed in college
This is all posible with year 12 chemistry knowledge lmao
no ur mom gay
I'm always so exited whenever I see Cody uploaded a new video!
I've been watching your videos for a while and I am totally hooked. I'm really interested in how you became so interested in chemistry, organic chemistry and how you got so good or smart with all these videos, and who or what other CZcamsr you like working with the most.
You can't leave us in suspense like that! ...... What do you mean by "That is interesting"?
VERY
Looks like he made sulphur by adding the sulfuric acid to that whacky solution?
Yeah, Iodide Ions are that strong of a reducing agent that they can reduce the sulphuric acid to elemental sulphur.
Would you be able to do a short video comparing the reducing power of Cl- Br- and I-? I know iodide is the coolest but it would be nice to compare the 3 (or 2) reactions as my school wouldnt dare do them
I have watched everything you have out and literally it will never be enough Cody NEVER
Magic!! Your videos are always awesome!!!
You got challenged by yourself?
jamer15961 Multiple Personality Disorder is a hell of a thing...
The Mighty Hercules Yeah it is
The Mighty Hercules Nah we're all cool with each other
No, look closer. It's some guy called "Cody'sBLab" that challenged him. Clearly a different person.
he has a second youtube channel called that "codysblab"
You still alive!
Absolutely brilliant! You can work marvels with the chemicals, Cody! A great video.
Keep the time-lapse shots coming! Adding that clock was a good idea aswell!
@Cody'sLab If you are taking requests could you make some white phosphorus? I saw a video about the discoverer of white phosphorus and how he thought he had discover the philosopher stone.
Has Cody'sBlab taken on a life of its own?
It's his clone for experiments.
Love watching your videos buddy thanks for everything
Seriously that's some nice chemistry. Really enjoyed the video!
You should make a video on extracting the iron in cereal
All that requires is a magnet. Not all that interesting and plenty of videos on it already.
"IodineFro..." *DEMONETIZED!*
Iodine is a precursor for methamphetamines, so I'm willing to bet that someone reviewing the video will completely overlook the fact that this method is really impractical and demonize because you gotta think of the children at all times and against all reason
@@nicholasgeere5125 Nah, Iodine is NOT a precursor for Methamphetamines (though some methods can use it in a catalytic sense). But it does boggle the mind WHY Cody keeps getting shit on like this. All he has to do these days is sneeze and they clobber him. There is NOTHING on any of his posts that I can't find more dangerous and clearer 'how-to' instructions elsewhere, yet THEY don't get 'strikes' and blocks. WTF is going on?
I see really detailed stuff (for some reason they keep popping up in 'suggested for you') on gun-barrel making, poisons, explosives, knives, swords, cross-bows, hunting bears with a spear, etc; not even an 'age' warning on them. Cody only has to suggest he peed in a bucket and, WALLOP!
Madness.
@@paulforster6229 But I can see why. Man is making legit bombs from nothing but a bucket and a jackhammer, and his videos are very similar to tutorials. Same with NileRed, he makes hypnotic sedatives, and explains step by step on how he does it. Anyone can easily pick up and replicate what Cody is doing, and it would end very badly. But that’s just the price you’re gonna have to pay for chemistry and your own creativity.
Love your video's cody! Keep up the great science!
Great job Cody!!
Cody can you test does stainless steel used at hydrogen generator produce toxick cromium (VI)
No, it doesn't. I know this from personal experience. You would require a much stronger oxidative power to convert chromium metal in stainless steel straight from oxidation state 0 to oxidation state 6 to make any chromium(VI). Good question though!
SamuelLegoMovies there is much conflicting information on that, I heard cheaper stainless will do it.
Well the stainless steel I used didn't have any problems in my hydrogen-oxygen generator. At high voltage and prolonged useage the sodium hydroxide solution which I was electrolysing did change colours a little, but this purple colour quickly faded when the power was cut. Me and my chemistry teacher have put this down to the small amount of manganese in stainless steel.
If the solution you use has chloride contaminants (this happened to me when using potassium chloride contaminated potassium hydroxide I had made) then this can cause the iron and chromium to be corroded and produce green and red solids, although from others I have spoke to this is most likely just iron(III) oxide and chromium(III) oxide.
I could be wrong, but like I said, personal experience has said otherwise.
If you actually wanted to make chromium(VI) compounds then there are much better ways of going about it.
If you use salt water as the electrolyte then yes you create chromium (VI).
Why did you clean the acetone after each salt can? Wouldn't it be faster to first dissolve all the iodine in all cans of salt with the same acetone and then distil it?
Your chemistry videos are the best!
Your skills have improved over the years. Good job much less safety issues also.
Wish CZcams was about when I was at school my life would have been so much easier lol
bill grafton nope. It is a constant distraction
I love the profile picture!
Cody you're just an awesome guy. I especially enjoy how you don't put on a character your just yourself.
I love watching you videos man. Where did you learn all these things?
I challenge you to extract iodine from iodine
Bruce Wayne that's meta af same as your profile pic and your name
HMB
Bruce why do you have a Batman dp?
Mmm exploding whale tasty
This is the most incredibly stupid thing I have seen today.
*Thank you*
Chall... Oh. OH! I see what you did there! 😃
i love your glass on glass bongslides
Cody I've literally wanted to try this for so long!
Cody ... the guy who challenged you is yourself xD
and the fact you responded in less than four minutes and forgot it was you is slightly worrying to say the least...
maybe you should have yourself tested for memory loss or psychological personality disorders...
im pretty sure it was intentional (either that or he is logged onto one and canyon (his GF) is on the other)
let's hope so, otherwise it would be a sad ending
I made oobleck from corn starch and Hydrogen Peroxide -(H2O2) and I put salt in just to see if a reaction occurs and the salt turned purple black and kinda blue is this iodide?
yes
Man, that guy who challenged you was a genius
So cool man, love your videos!
Nice heating mantle u got there ...
It would be a shame if I spilled hot sulfuric acid on it.
This video was sponsored by wal-mart
I was never great at chemistry in school, it's not part of my job either. Watching this though is the most interesting thing ever! Love the channel!
Cody, I wanted to say I think your channel is awesome. You’re basically a genius but I love how you do your videos. They have that creative/inspirational try it yourself look. (Just don’t do it unless you’re Cody) and you teach as you go maybe it’s just me but I think chemistry is awesome. Keep the videos coming! 👍👍
I challange you to make silicon carbide.
I have cluster of crystals made at Washington mills i can send to you if you need it
You should really get some glass stir sticks.
NerdAmongUs often times a thermometer is just as good
and you get a duel usage with a thermometer, since it gives a temp reading.
Also, Cody, if you ever see this, I am down to send you a box of glass stir rods, in various diameters and lengths. Just send me shipping, and we are good.
I was actually looking up ways to isolate this and couldn't find any good videos on CZcams until my favorite subscription released a new video
Hey Cody I found another channel that you frequent and I understand why. It is Isaac Arthur's channel! I love it! I also been loving your videos much longer! So keep up the good work!
Cody always has to one-up my bong.
I guess cody is still alive then.

Neok1337 or even banned
found you through big clive. great channel man
I just have to say i have been watching your videos for the past year. Im not a chemist or even understand really what you do. But i love watching you turn one thing into another. P.S. the end was great do that more.
mercury from tuna a d tuna cans next? or maybe fluoride from tap water next???
You mean fluorine
Fluoride is the Ion they add to tap water so he was correct. Also the concentration of fluoride in water is so small he would have to process a bunch of litres, not to mention other absorbed minerals.
holy shit you people have flouride in water? someone explain the reasons behind this please
Fluoride from toothpaste would also be interesting, and a lot more practical than from tap water.
Fluoride in low concentrations has been proven time and time again to improve the dental health of the people drinking it. It reduces risk of cavity and increases tooth health. Its silly people actually believe its dangerous in the concentrations added and its a shame that this advancement in water purification is looked negatively apon.
Extract elemental sodium from salt
Then react it with water!
@@lanceshallenberger7563 bow we're thinking
Lance Shallenberger He could melt it, and force some electricity through, which would produce Chlorine Gas und Sodium
nurdrage has excellent videos on turning sodium hydroxide into pure sodium
Ive been waiting for this
I love how the original audio comes from my right earbud, but all the voiceovers are from the left
Just what I said! Sodium chloride!
Cody, why do you have bong accessories on your table?
Hey Cody, I love your channel!
What do you do with the byproducts of reactions? Do you save them for reuse in later reactions, or store them indefinitely? I assume some of these things are not safe or legal to dump.
You've got a point. Maybe Cody should add some content in how to destroy or make safe some of the dodgier stuff. Nitro glycerine for instance, easy to make, not safe to store, can't just keep setting it off in small bangs; safe way to dispose of it is to dissolve it in alcohol then degrade it with caustic soda solution. It would be nice to see Cody do that sometime with that and other problem materials. Maybe then he wouldn't get so many strikes.
95% of videos i have no idea what is about and what im i watcing. But after 2 years i still enjoy it.
Welcome to America, where we even put sugar in our salt!
But has anyone deep-fried it at the state fair yet?

It is an anti caking agent and wicks water from the salt
Could you do a video or post on the best way to obtain pure iodine?
Computerman 21 buy potassium iodide. It is sold bulk on Amazon. Then mix in HCL then HO. Find a way to sperate the iodine from the potassium chloride. And bingo

Wow, that's some beautiful glassware.
Hey Cody.
Love your videos.
I live here in flint Michigan.
Honestly I don't think the water is really as bad as they say.
Is there a method we could use to test it ourselves without sending it in?
Thanks in advamce
I challenge you to extract silver from DVD.
They are coated with a layer of silver inside.
He can just scrap the top layer off and extract silver from it.
DAVID 143 SHAH you would need a lot of DVD’s to get anything worth doing but it’s possible
James 18 that's what Cody do .
do DVD's still exist? dang, technology movies slow lately. pun intended
Yes, DVD still exists. I have a lot of discs in my house right now
Recently challenged by himself lol
Nate Hazard really?
I'm not even halfway through the video here I love the clock in the background I think we should name it or use it a lot more often or something. Great video!!!!! .........so far. I'll continue watching enough from the peanut gallery
I love how you challenged yourself... took me a sec to realize that. I had to rewind.
Demonitized.
Only CZcams-Chan can say that xd

nonamelikethis probably because of the crusty white stuff
HAHA you used your own alternate account to challenge yourself and presented it as though someone else had challenged you LOLs
Best video you've done
In 1986, my chemistry teacher would always say,
"Chemicals, chemicals, everything is about chemicals."
He was accurate when it comes to basic human experiences but if you go farther down, everything is about Higgs boson and then what ever that is made up of.
