Oh man, it was really cool seeing my glassware in your video!
NileRed it’s cool to be in the RUclips science group
You and cody should do a colab! I bet he could get better results in your lab and it would be cool seeing both of you working on this!
NileRed ah my favourite youtubers together 😍
NileRed Colab!!
that's what i wanted to say that Wow he got nile red's glassware amazing
This could've been confused as a NileRed video until you used a carton of frozen goat milk as a glorified ice cube lmao, never change man
you are my new favourite reference-based youtube account.
Does anybody else love it when these chemist RUclips's refer to each other. Like Cody did with the NileRed flask.
Sleeps for three hours, "so here we are, after I've taken a long nap", this guy!
Or was it 15 hours?
Cody'sLab
:D
Or was it 27 hours
Or was it 39 hours
i bet cody slept only an hour (i suspect he sleeps while standing) and wants us to think he's normal so he wound the clock forward 2 hours.
got him!
I love how accessible you make science look for people. It's like watching someone make furniture out of their garage or programming video games in their basement. It's the type of scientific media we need most to make the younger generation more interested in the sciences. Hopefully youtube stops dicking with your monetization.
Cheezits I totally agree, I always was slightly interested in science and chemistry in school, but never quite understood a lot of it. I've learned more from Cody on RUclips than litteraly every science course I've ever taken.
Honestly, more kids interested in Chemistry would probably be a bad thing... that shit's dangerous.
yaksher educate them. Not educating them is far more dangerous then chemistry
Im A kid and i love school but cody is more engaging to me
Cody also apparently has far more cash than the average school does for science. Gotta love how he causally x-rays a roll of gold foil that he spent a few grand on with a device that probably cost just as much.
Cody fooling us with golden Wolframium
I was actually expecting some of these chocolate coins tbh.
Skult nah I don't think so
skult u traitor giant loving buttmuncher
good comment tho i like u
Wolframium lol
lol, he'd know if his bar was tungsten
because he'd have to heat it up six times hotter to melt it, for one.
I know you just wanted to use bromine to show off your fancy new fume hood Cody😜. Can't fool me
dang. someone figured it out.
Fun fact. "Rose" Gold, an invention of the middle east, is a Gold-Copper alloy. Costs more than pure gold, but *worth less.*
stonks?
@@canigetsubs-pm7hz stonks.
Rose gold is so beautiful. It's my favorite color by far!
Piles of bodies on the sidewalk under the fume hood exhaust..
Coneshot nah he lives in the middle of nowhere
Good joke though.
he lives in logan in the week he said on a video
Ahahuhahuhuhahuhahah! Nice Joke! My ass dropped out! =D
yeah really, he has no idea what is on the other side at any time, you can see he exposed himself to a dose of bromine already, he means well cept he might be on the spectrum
Yay, another precious metal refining video!
I'd say I love this series so much, but that's also true of every other of Cody's series, so it's kind of redundant.
Cody is a genius. None of his videos suck.
Micah Philson I agree
😅😅😅how is that possible
one of the only channels where I see a video and click, no matter the content.
my favorite is cody's mine
lmao the nile red flask
Good guy cody
2 of my favorite RUclipsrs! Too bad RUclips is having a crackdown on chemistry videos with channels like yours, NurdRage, styropyro, etc. I think chemplayer got shut down, what a shame.
Fuck RUclips and their stupid platform, this is some of the best content out there, it’s like they want their site to be filled with cringey videos and bullshit.
RUclips is completely corporate, so yes, they DO want their platform full of mindless dross and NO, they don't want information disseminated.
Yup favorite youtubers
"Bottle of frozen milk in the cooling water, keep it cold."
Absolute mad man
Goat milk
Really excited for the big gold waste recovery video that's undoubtedly to come! :P
Bjørn-Oskar Rønning the one where he burns down the house to refine out the gold?
Craig Hills
That's what we in the business call "doing a William osment"
Matt G oof
Matt G to soon
Matt G so we are waiting for Cody to do a Willy O huh?
*uploads next vid* "GUYS, ALL MY BEES ARE DEAD"
I wonder... what would happen... if you fed them with a diluted gold/sugar solution... most expensive honey ever?
lol bromide poisining
Well, gold ions are toxic^^
martijn ellenbroek stop it stop it. It hurts. LoL
In before the FBI shows up
That's the hardest earned $7.50 I've ever seen.
Yep, I was thinking he would make like $1-2k, but you spend hours and hours, plus the price of chemicals not taken into account.... not worth it if you try to make profit. But totally worth it for the science :D
Thanks Cody for having the time and money to do this.
You gotta add profit from youtube and it's probably very worth it. ^_^
RUclips doesn't pay him, they don't like chemistry videos on their platform as it's "dangerous." Patreon is where he gets most of his money.
RUclips has been cracking down on chemistry and shutting down channels.
Yes but I was talking for everybody that would like to try that to make a profit. Not anyone will get thousands of views.
Plus I doubt his RUclips earnings from such videos are very high.
Cody, either your mike is very close to the exhaust hood's motor, or the motor is so large that it's adequate for some wind tunnel experiments that you haven't mentioned yet.
he canibalized an industrial sized fan in the last vid
At first glance I thought that was some sort of chocolate fountain in the thumbnail 😂
Science with Katie coming from Cody, it could very well be Uranium laced chocolate syrup hahahahaha
Science with Katie I see you every where I go like in the comments of gmm
Science with Katie but.. Your name is science with Katie? How would you not know this was scientific glass. Guess you are a cute girl, probably the reason for obliviousness😉 jp
So I guess I wasn't the only one!
Science with Katie I thought it was one of those cakes where you pour molten chocolate on and they melt and reveal something
Why is your kwijibo telling us that gold is tungsten?
-edit
Since I made this comment without listening for an extra 30 seconds, I should probably explain why myself:
After having read the manual, it has 3 relevant modes: Alloy, Alloy plus and Precious Metals. If you want to get an idea of what contaminants are in the sample, one of the alloy modes has to be used as the PM mode only tests for Ir, Pt, Au, Rh, and Pd.
For those who are curious, Alloy mode measures Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, W, Hf, Ta, Re, Pb, Bi, Zr, Nb, Mo, Ag, Sn and Sb while the Alloy Plus mode adds Mg, Al, Si and P.
You now know what I know.
This explains nothing to me. All I still see is bad ROM code, and that that ROM should be swapped out with next-day service by a technician who flies in at the company's expense. Cody stated unequivocally that its not a hardware issue with the instrument.
Alright. You want more, I'll give you more.
The gun works by x-ray fluorescence spectroscopy. It has several different x-ray beam energy settings (10, 20 and 40 keV or something like that). When you bombard an element with x-rays of a particular energy they re-emit photons ranging from the hundreds of eV to tens of keV (I think due to core electron ionization, as opposed to valence electron ionization).
The mode you choose determines the x-ray energy and for some x-ray energies, the fluorescence of certain elements is indistinguishable from the fluorescence of others. This is the case for Alloy Mode.
"Fix it in ROM" you say. "That r dum" you say. No, actually, the problem is deeper than that. Core electron ionizations tends to have relatively high half-lives before an electron from somewhere else drops into the missing electron slot, on the order of 10's of seconds. If you take a sample with the tube energy at 40keV and then switch to 10keV to get a different spectrum, the data will be contaminated by non-decayed core electron holes from the test at 40keV.
In my original comment I wasn't sure which of these two explanations to give. This one is much harder to understand although it is more broadly useful. Also no one had told me "fix it in software" yet.
I did the same "not listening for 30 more seconds" but immediately paused and rushed for "Dude, wait, wot? Wolfram!? Y ain't dere no Aurum? Woot!" =D
Thanks for the heads up m8. Sometimes the comment section really rocks!
vertex rikers: its interesting when you look for the manual for it, its easy to find but it says its not to be distributed or copied in any form. I'm don't think they quite get the concept of the "internet".
Well, many times such clauses, even tho 90% futile, are being added just to give the provider an edge in a hypothetic court case - like when someone creates a huge archive and redistributes without permission. Guess that clause ain't considered effective (regarding personal use cases) even by the provider =)
Hey Cody! I just started my first college chemistry course and I am loving it! I have been watching your videos for a while now and I really appreciate how you bring chemistry to youtube. You leave nothing out and make great videos! Thank you so much!
Funny seeing comments like this, and knowing you've probably already graduated.
Bromine. What a lovely element. I used to work for a shipping company that used to import huge flasks (in 20 ft container frames) from Israel. They would be exported back home with some liquid Bromine 'ullage' in them. One of these flasks was damaged whilst stored in our yard, and a small amount of ullage escaped. It took the paint off the trailer it was on, several containers nearby, and ate several holes into the yard floor. It also meant half a day off for me, as HAZMAT teams quarantined our yard, so I came back from lunch unable to re-enter the office, and my boss told me to go home, as the ullage had 'wandered'. Lovely.
So glad you got that fume hood. Makes me feel better watching you. Keep up the excellent work Cody
You should try and refine metal from vitamin tablets
Mercury from expired vaccines for the oil-industry-lead-poisoned-conspiracy-believing-parents.
Andrew McMidget visits my Chemistry channel
Damian Reloaded An anti-vaccine person? Your brains must be more dashed than the sentence you just wrote.
He was mocking anti-vaxxers actually, hence the 'lead-poisoned conspiracy-believing parents' part
Stephen Beales Didn't realise, anti vaccers are so stupid it can be hard to tell.
Man I just wanna say thank you!
These videos are just really interesting, learning the chemistry behind the refining of elements, we all know that Cody must have put a lot of effort in to making these videos understanble and possible
Great work Cody! Looking forward to the next one!😊😊😊
It's so nice, Cody's laugh when something chemically funny happens is exactly the same laugh we electrical engineers utter, when something short circuits... ;-)
I was like "Have I learned the periodic table wrong my whole life?"
Are you on a polyphasic sleep cycle, Cody? If so, that might be an interesting video: just hearing your take on how it's working for you.
I caught that, and came to ask the same question.
No, I just dont sleep much.
@@theCodyReeder :( sorry man
OMG! I love this series so much! I've been rewatching the older videos simply because they are so fun!
One of the better looking bars you made. Beautiful crystals
"Fortunately, I now have this X-Ray gun"
this only makes sense in Cody's videos haha
Try extracting mercury from swordfish filets!
This was amazing to watch, thank you. It's incredible to watch all of the chemical reactions take place. I love how detailed you are when recording.
I love how Cody shows multiple ways to do the same it really broadens your knowledge on a topic
I can't wait to see you carve yourself the diamond playbutton!
Guys I found another Justin Y.
ninjA!!!up up up
I want him to make his own diamond
Stop
dont give hime idees or nvm do give him idees it could be fun to watch
I really respect your sleeping patterns!!
Your flask at 13:00 is incredibly intimidating.
1300 ml of elemental Bromine and Chloroauric acid in solution is something I don't want to even think about handling. Kudos to you for doing it for us, Cody!
Thanks Cody for having the time and money to do this! I'm big fan of yours!
That still might not break into profit margins when you consider the time put in. We need more gold.
Atlas WalkedAway Even then, the profit is never going to be that huge.
But! You still need to remember, that the time spent is paid off through You Tube; perhaps even much more than the time's worth. So in the end Cody had made good profit; not much, but still, good profit.
Plus gold is good investment; you never know when the economy is goning to shit in the future, the dollar collapses, or inflation hits sky high levels. Gold on the other hand,, retains its value throughout the ages.
black ops Gold retains its value until the very first time that it even remotely seems like we might have a viable plan to mine asteroids or other celestial objects. Call me a blue sky dreamer, but I'll stick to most of my reserve being food, weapons, equipment, and land.
Nate Yeah, I hadn't even thought about the reagents and the wattage. Suckage.
If the economy goes that far south, few people will want gold. They will want food, water, gasoline, and medicine. You can't eat gold. No one will buy it when they're hungry.
Awesome. Just earlier today I was scanning my sub box extra well to make sure I didn't miss a Cody's Lab video. Getting close to needing my fix
Verlisify didn't know you watch Cody
Hello there :3
Fuck are you doing here dawg
There is a reason Verlisifys videos are blacklisted by youtube... He is drama cancer...
I love your metal refining and recovery videos! Surprisingly they are not how I found your channel. I was looking at mercury stuff and found the video where you put your hand in mercury. I loved your presentation style and watched more of your videos. Here I am watching every video you come out with!
Love the fumehood. You can even see it extracting the oxy torch fumes. Excellent setup you now have.
what about price adjusted for youtube views I bet that gold has a high commercial value
he probably makes more from viewers than what thats worth. what a good effort, i hope cody keeps this up for years to come
Honestly I've "made" far more off the tax savings then anything.
Cody'sLab hahaha oh shit yeah mate, maybe I should buy some gold and deduct it
How do these tax savings work, for us not living in stange freedom lands overseas? We have to buy our stuff out of pocket and no taxbreaks or anything, getting skinned on any purchases too. Got myself silver and gold Perth mint dragon bars yesterday, I am METAL (read with death metal growl) now too ;)
Cody'sLab I guess you can write off all of it as a business expense.
Woot got through Calculus final with an A today and Cody uploaded.
W x2
Crazy how you have 1.4 million subs, good for you Cody. I’ve been a subscriber for quite some time. Love the content. Looking forward to any mining videos you make in the future
Words can't describe how much I love this channel!
mekanism 1.13 looks prttey good
Hey, something I get!
great video my friend ....you truly need you our Lab or teach at a University my friend. P.S. love the new icon pic.
Absolutely love the longer videos. I know you can't do them all the time but they are so great
I love Cody's lab videos because they're informational
I have a geochemistry midterm to study for but I got this notification. This counts as studying, right?
of course it does! ;)
Digit975 Good luck on your tests, you're gonna need it
I find Cody is quite useful for geochemistry studies, he taught me all about fire assays and inquart which came up in my second year university exams. So yes!
Thanks for the video, Cody, You make chemistry so interesting, only wish i had seen this when i was at highschool, might have taken more interest in the subject.
I barely understand basic chemistry, but i love your videos so much. thank you for making them and educating all of us, Cody. If even an art student loves what you do, you're definitely doing something right.
Cody has the brain of a scientist but the heart of an artist :)
Another great video, I can watch your videos the whole way through and not get bored for a sec!
Alchemy at its finest!
Was that an acetylene torch? If so, don't use that for gold. Oxy-propane is ok, but in a lab, we would not use acetylene, it contaminates the metal.
What with carbon? The x-ray wont pick that up...
Cody'sLab Honestly not sure. If we were fusing glass to gold, acetylene would total mess that up if the gold were melted and cast using acetylene.
the fact that the xray wont pick it up is even more reason to not do it sonce you wont be able to quantify the contamination
thats probably beacuse you were trying to get the gold to react, or at least form some wierd alloy or mixture. pure gold is probably fine because is unreactive and carbon wont bond, the worst is geing that wierd crud on the surface.
Industrial acetylene has phosphine in it, hence the smell. Maybe the crud comes from gold phosphide?
WOW! Your final product looks so much better!
This is one of your best videos in this series
We require more mining videos :D
And i was here so fast its processing :(
me too :/
Håkon Nessjøen lol, fortunately it only took a couple minutes.
Haha! Great Video. Just the look of that bar, at the end.... That had the look.
And your number, 98.88... Call it 99% for laughs...
You are 1 guy, with some equipment, some knowledge, small batch size.... Without the kind of large, heavily equipped lab that a major gold miner would have on the premises, and the people, with years of experience.... It would be hard to go farther.
What I'm trying to say is, for 1 guy, working in his garage.... That is a VERY impressive result. I'm not sure the average viewer will grasp, what a great job you did there. Well done Sir.
this is my favorite series on RUclips
Cody, did you work at Black Mesa Research Facility back in the late '90's?
No he definitely worked at Aperture Science
Regarding that x-ray tool. Does the accuracy become affected by the environment? Like that gold was analyzed on the wooded table. Are the elements in the wood/finish being analyzed as well? How far does it penetrate? Im sure the output is adjustable. How is it working? What is the spread?
brian faini surface contamination can skew results but they beam only penetrates a few nanometers
see this is why it needs another video. Put it this way a sheet of gold as thick as aluminium foil will block all the return x-rays while aluminium foil will block almost none. also since people keep asking the x-ray emission coming off carbon is so weak that even the air is enough to stop it.
Cody'sLab another video on that would be fantastic. Seems like a really interesting tool.
Might be the best money you ever spent, although that software update feels like a ripoff.
It IS a rip rip off. Probably just a few bytes of code that are changed.
Super cool. Loving these chemistry vids.
Cody, I cannot tell you how much I love your videos!
Good video
Wait.
Does the x-ray gun put gold in the tungsten category?
Mircea Crafter software issue
yeah he mentioned it a bit later on in the video
What happens when you comment without watching the video
yeah, It is set up for detecting trace amounts of gold and so when I test something with a lot of it the software is like "wtf! ummm... oh I see must be tungsten!" I can fix this issue by sending it in and paying 1000$ for an update but its really pointless since I can look at the graph of energy returns myself and see that it is detecting gold.
Mircea
The explanation makes sense for a $2400 instrument. Not ~$24,000, or whatever it was. I'd want a software guy to come to my door in a Mercedes and swap out that ROM, stat.
*4.5 hours later* So! Here we are after I've taken a long nap.
Cody is from another planet than us mere mortals.
Thank you for another great video Cody.
*THANK YOU KITCHEN GUN*
I don't know what chemicals you have in stock, but wouldn't it be easier to just distill bromine directly from KBr and Sulfuric acid or KMnO4? Without going the extra mile with HBr?
Where are you getting chlorine? Is your NaBr crude? Small amounts of NaCl in NaBr forming Chlorine would oxidize leftover Bromide. So you could use NaBr in excess. Sorry if I'm overseeing something obvious. But thanks for the upload I was shocked how fast the gold reacted.
I love the longer videos Cody, Keep up the good work
thanks for the spreadsheet at the end. very nicely laid out!
Why frozen milk? Has it any Thremodynamic reason?
what I had.
@@theCodyReeder glad to know you understand the rich thermodynamic properties of frozen goat milk...at one time is was a highly guarded secret...
Hears my little nilered flask
me : do a collaboration
Wow. One of my favourites of yours! Using bromine, awesome. Thanks for uploading.
Looooove to see you refine it to 99% and higher!
Cody you make some incredible content! keep up the good work!
nice NileRed glassware :D
No ads what the frick youtube
RUclips has almost banned making money from Chemistry videos.
easydoz1 I think one of the RUclips employee don't realize that it's a educational video
I think youtube is forgetting about what makes youtube popular... Its high quality creators...
I got an ad...
I never saw any advertisment on Cody's videos. I just use an ad blocker like any normal person out there. :P
Great video Cody.
I appreciate that you put the spread sheet at the end
Where did you get that handheld tester, and how much was it? I did a quick search last video, but I couldn’t find it.
I got it for a steal of 15,000$ you can contact Olympus and they will set you up with a demo, classes, and might let you have one for 30,000$
xD
wow, half of a huge price, nice catch!
Wow I didn't expect the comertial gold bar to be 100% pure, I wonder if it could be posible for you to achieve 100% purity as well
More likely a rounding error of 99.99%
It wasn't necessarily 100%, just enough that the XRF was like "yep its pure tungsten"
100% +/- 1.3%
Definitely very very cool to see you refining gold
I took a chemistry class this year and it's crazy how much I understand! I learn so much from your videos, its helped me a couple times on quizzes 😂
This might sound impossible but.....
Is there any way you can re-refine air into its purest form?
*PETAL CRAZED CABBAGE* you can filter it to get rid of impurities or distill it into its main components
You could filter it to remove contaminants and particulates and I do believe there are machines that can take oxygen from the air and leave most of the other gases behind but I am not sure, air itself is a mixture so I don't know if you could refine it. Hope that helps.
what do you even mean?
I'm assuming by air you are referring to oxygen, the breathable part of air in which case yes. Talking about just air as the mix of gasses then also yes but nothing pure
Any gas is breathable as the word only defines a mechanical function of the lungs, you can breathe pure carbon monoxide just as mechanically efficient as you can breathe pure oxygen for a certain period of time, though it would not be advisable to try either.
Thumbnail looks like some shit outa alien
well the you-tube "auto thumbnail maker" thought this looked most like a face.
I loved how you lit the torch with the molten gold! Haha great video Cody!
Nice to see you expand your lab setup, gg.
just add a packet of frozen goatmilk for cooling.. *ok*
Can you please extract lanthanum and/or cerium from lighter Flints? Like if you agree.
Always a good show. Thanks Cody. Can't wait for your next video. Carpe all the diems!
A very HD picture of that gold bar would make for a good phone wallpaper. Those crystals are gorgeous!
Yo do me a solid and be my A Level chemistry tutor lmao
Doesn't dissolving gold and dropping it out with sodium metabisulfate give you 24 K gold. Also can you do a video on purifying paladium and silver.
yes, unless you use too much, neutralize the acid, and drop out everything.
What about the second part of the question :)
What about saying thanks for taking the time to answer one of your questions?
lol whoops
thx for noticing
I love your channel man, keep being amazing!
I learn more chemistry here than chemistry class. Something about visually seeing the process done makes it that much more easier to listen and learn to.
so youtube new i wanted to watch this it put it in my recommends on the side of another video. why not just notify me? I always watch cody play with gold or dredge a highway or dig a hole or just whatever.
you check the /subscriptions page at all?
that is weird...because of all the years and complaints of peeps i always land on the sub page and it shows everything, and if i missed something, i just look on the left side at the subbed channel names and they'll have a number of how many i missed from them...and i do get all 870channel vids on the sub page...
Lol alchemy at its best eBay junk to tungsten with the appearance of gold
What? xD
Cody, the fact your up at 3am looking at your experiment, indicates the power & drive of your insatiable curiosity.
Cody makes chemistry look like magic
