Hi Cody, here's my NASA gold and mercury story - My wife broke a thermometer on her gold wedding ring. Mercury completely coated the ring making it a shiny silver color. All the local jewelers I called were stymied, none had a clue how to remove it. I called the metal plating lab at my center (Goddard) and they said they would have a look. After much discussion and calculation, they reverse electroplated it, the mercury fell away, and the ring is fine. As a result, two NASA technical papers were published on the specific process citing my wife's ring as the test subject. Cool!
Simply heating to solder temps vaporizes the mercury, use a powerful exhaust fan or a respirator.
Dan... First, this is from 6 years ago. Second, the ring is from the 1750's and experienced men with PHD's in metallurgy and it's history determined heating to be an unviable solution. Mercury was in direct contact with the solder holding the crown and stone in place. I trust that wisdom, here's why. Simply heating to solder temps as you suggest would have likely destroyed the ring, jewelers silver solder of the 18th century did not have the same composition nor melting point as in modern times. Details matter.
Never considered the jewelry aspect, very little heat is required to remove mercury from placer gold old time tailings.@@birdseyeview1543
@@danhelwig Another FANTASTIC example of how USELESS NASA, AND ITS STYMIED EMPLOYEES REALLY ARE. 😂😂😂😂
My friend told me that he made Lithium react with Argon.
LiAr!
xD
He would be lying. LiAr is not stable at normal pressures, it needs to be under 1.624e+7 psi. That's 16 million psi.
Dan Bodine what a great way too remove the fun from a joke.

There was a young lady named Bright
Whose speed was much faster than light.
She went off one day
In a relative way,
And returned on the previous night.
Mitchell Maytorena nice
Mitchell Maytorena 👍
There was a young lady named Cass,
Who wished for a decrease in mass,
She said 'What I need,
Is a negative speed!'
But she's now a tachyon, alas.
A shame Brady and Grey didn't show this one.
ahaha, physicist limericks!
thank you cody. as an adult male that still enjoys learning about science but um well, got drunk instead of going to school and getting good grades to continue in a science oriented direction. i have learned quite a bit from you. which is totally ironic in the fact that i am sitting here having a few beers and learning. very awesome man
You’re here now and that’s all that matters :)
Cody, stop using your great grandmother's decorative plates for science.
ngharo lol
He bought them from a thrift shop, as you can see in his refinement series. just saying haha
Hahaha
Lmao
@Cinder Fall 4 years ago they are using lol rather than lmao and lmfao
Who else learns more from Cody than their science teacher 😂
frog I do
who has a science teacher?
frog how? Don't u mean who

I think you should watch a channel that teaches English too. ;)
it's amazing to see you get on the trending list, I've been with you since 50k subscribers and first started watching you when I saw a recommend video in my feed and I said "huh looks interesting" that video was amazing and made me immediately subscribe
This is my favorite channel! :) Love you Cody!!
Welcome to Cody'sLab home to mercury, mining and vacuum chambers
and explosions
And BEEEESSSSSS
ya like jazz
Ya Boi yes, yes I do.
Perhaps.
For some reason I understand you better than my chemistry teacher
I love your channel and experiments but most of all i'm absolutely impressed with your knowledge and the ease at which you operate while carrying out experiments.
Thank you for everything Codyslab you're my favorite friggin channel.
I'm a simple man, if I see a Codyslab video I press like.
Spuddy same
A simple man with simple needs.
The russian memes would not let me go
Love your profile name!
How to make the worlds most expensive chalk.
Not exactly, no.
Does anyone else realize he turned gold into a white powder seems very interesting to me how gold became a white powder like chalk has anyone heard of monoatomic gold spoken as about by David Hudson in his lectures
Hey Cody! Just wanted to say your channel is awesome! Some of the stuff you do is amazing... Keep it up!
Really enjoying those videos, you really are the guy who does all this stuff because "I want to know" which is an awesome attitude :D
How long till Cody finally goes full on Breaking Bad?
Peter Burrell I hate to break it to you, but that show is no longer with us.
weredragon100 stop destroying my dreams!
Bad is already broken.
this vid brought me back to my good old junkie days
'In today's video I swallow an entire gram of methamphetamine to disprove the notion that a single does always leads to addiction!'
You know, because chemistry is often such a big part of your videos, it would be cool if you did a series getting a little deeper into the chemistry. Like describing why molecules have certain properties, which elements are likely to replace each other in them, etc.
I know a bit about this stuff, but it's been a long time since I learned it all and I'd really like to know more.
I've continually enjoyed your videos! Just keep yourself safe with any number of those fun solutions!
I remember a time I accidentally got some developing agent onto my cloths, which was well known to cause cancer, but a SUPER big molecule, so less of a concern, so long as you don't ingest it. In any case, be safe and keep being cool!
Love your videos Cody! I always learn something new!
13:37 long video and +100 likes people know it's going to be a good video.
God :-O 8239*
3:36 so thaaats how they made candy cigarettes. No wonder its so hard to find nowadays.
this is my favorite channel on youtube. ive been with you since 2500 subs
almost at a million subs! great to watch the channel grow!
it looks like chalk, it feels like chalk, but does it write like chalk?
Didn't even occur to me, I guess it would though perhaps leave a silver streak of mercury gold amalgam.
Cody'sLab rich people just got a new thing to waste money on :P
Cody'sLab some dental amalgams can leave a silver streak when they are hard enough. Cody you could find an old dental materials book that has recipes for mercury amalgams and the properties you can get from mixing mercury with other metals. It was really studied back when mercury fillings where used.
It should do, if it's solid enough not to crack. I've used literal lead pencils more than once, they're fun to make.
You have to show us!
Any updates on the digester?
So close to a million. I subbed at 36k congratulations!!!!
Almost to one million subs. Nice. Love your vids.
Hi Cody, Awesome stuff! Though solubility in mixtures of metals or mixtures of salts is not really analogous to solubility in aqueous solutions. For example at sufficiently high temperatures gold and mercury would behave like miscible fluids, and when lowering the temperature, the precipitate that forms would be an alloy of gold and mercury, not pure gold. Check out metal phase diagrams to see the steady-states for these dissolving processes in terms of temperature and composition. It seems likely that you have made a semisolid phase, and that the solid portion you removed was not gold but the solid portion of the semisolid melt, which is a specific phase of gold and mercury. The liquid portions were so similar in density and had so little gold because even with zinc in one mixture, the eutectic point for mercury plus basically any metal with a high melting point will be almost pure mercury. The solid phase that was removed probably has the higher density and 'solubility' you were looking for. Let me know if you have any metallurgical questions and keep up the good work.
I like your outro Cody!
Yeah! Me too. Do you know the song?
another trending video! killing it Cody!
your channel has gotten huge good job
Imagine the pain in the ass it would have been to try and recover the gold from the mercury toilet.
Almost at 1mil subs!!!!
Great Video Cody!
I love your videos Cody :D
Thumbnail was written by a caveman scientist.
Lol true
That chalk from the gold and mercury is very interesting.
love the vids Cody
Awesome video. Great frequency of content too! Keep going"
You should have named the video 'Making the world's heaviest liquid' with some crazy thumbnail. Do you even clickbait Cody?
"He DISSOLVED GOLD in mercury and you will NEVER GUESS what happened NEXT!!!"

much dissolve, such wow
Nice video, I always wondered how much gold would dissolve into mercury. And damn, almost a million subs!
I'm binging older Cody'sLab videos again and my god, I love these videos so much
SO close to a million subs !!!! LETS GOO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Current methods for extracting gold from ore require cyanide. Can you make a video demonstrating this process?
Getting close to a million! Keep it up!
Awesome video dude!
From your experiments, I think you've made the assumption that dissolving gold in mercury will not change the volume of liquid, therefore you can find solubility by looking at a density change. Is this necessarily true -- does dissolving X mg of gold in (say) 10ml of mercury still result in just 10ml of solution?
Your are right the volume will increase but only proportionally to the mass of gold dissolved in the mercury. The density is always just the ratio of the mass and volume and as the mass increases faster than the volume, the density is increasing.
What happens to a weighing balance in a vacuum??
Akhil Sukhthankar That'd be cool, to measure the weight of the air pressure.
Probably would need re-calibration.
There would be no difference because air pressure presses on all the surfaces equally. To measure the "weight" of air pressure you'd need to pull a vacuum on the bottom surface of the scale.
If two objetcs with diferent volumes where in the balance, you would be able to see a difference because the Buoyant force of air would disaper
I'm not sure about it, but there should be a spot under the surface where air pressure pushing up will not change (Where the surface contacts the sensor) and this should make a difference between both areas resulting in a "lift effect".
Nice, I can expect another mercury video within the next few weeks!
I'm not at all a scientist, but I think all of your videos are so entertaining and interesting! Great job!
Wait, I know that 1g of water is 1ml but how does displacing water make it have more mass?
I'll give two explanations they are equivalent but use different methods to describe it
Exp 1
Because displace the water with the mercury creates a buoyancy force upwards on the mercury relative to the amount of water displaced, this reaction to this force (newton's 3rd law) pushes down onto the water and scale increasing the mass shown on the scale
Exp 2
The displacement causes the water level to rise so the pressure at the bottom of the beaker increases (as Pressure=densityX9.81Xheight) as force= pressureXarea the force on the beaker and scales increases, showing an increase in mass on the scale
Let me know if you don't understand what I said and I'll try explaining it again
Thanks! Yes that makes sence
So, a question I hope Cody will have time to answer: let’s say I had 10 kilos of gold and wanted to transport across the country (moving)...and wanted to put it in a form that anyone trying to steal something would overlook it. This sure looks like an answer. A big plastic tub of these “chalks” labeled lime pellets or something. Other ideas?
Alan, another idea: Don't try to scam the brothers. You only end up to the river, and your last tought would be why didn't graduate instead to be fool opportunist!
your knowledge is impressive!
almost 1,ooo,ooo subs !!!!!! love you cody
Get a haircut when you hit 1 million, Cody. ;)
You should try to extract metals from a catalytic converter
Just love your videos.. Awesome channel
always interesting, another great video!
I am watching this from an airplane how cool is that
pretty lame.
how cool is that

Love your vids never subscribed because they were on my homepage, youtube should fix this honestly you'd have more subscribers when they stopped showing up however had to look you up noice vids keep up the work man
Lol a 33 minutes long advert before this video by Tai Lopez
skip
***** If only i thought of that before watching it all
Hey Cody I wonder what will happen with Coke and Mentos in a vacuum chamber I wonder if it would add gases to the vacuum or just have no reaction
It would add CO2 to the chamber and get it all messy.
My guess is that it isn't possible in the conditions Cody has available. What I mean is that in order for that to work, the Coke and mentos set up would have to reach vacuum first. This takes a while. And while doing so, all the carbon dioxide in the coke could've boiled off. However, if he does manage it, it's gonna be great cause the air will expand more creating more fizz. Either that or it'll pop quicker and not much foam will come out.
Arnav Wadekar Its imposible to do, and dumb.
Carson W
I would like to see that as well.
My prediction is the coke would lose all its solvated CO2 and become a flat sugar water, which will react very weakly to the mentos.
Wow I'm actually impressed by that scale trick to get the volume. Never seen that before, but that impressed me 👌
very interesting video man, big fan
13:37
Why?
@@tylerhoblet1458 leet
How is he measuring the volume with a scale?
1kg of water = 1 Liter , the bottle cap is suspended from above with a wire, while plunged it supports the weight of the water directly above it, by pouring the mercury inside of it, you're displacing it's exact volume in water out of the cup, that water will weigh on the scale instead of the cup, you take the difference in grams and convert it to volume :D
So 1 gram on the scale is 1 ml of water?
At 4 degrees yes, not quite at room temperature. It works with other liquids too.
One of the few youtubers who regularly does experiments with expensive metals :) Quite interesting!
I just want to know one thing: who are those 181 who do not like this video or any of your videos in the first place? What are they here for precisely, to see what?
I love your videos. Keep 'em coming.
Mercury on table at 3:49
I was wondering if anyone else noticed that cheers mate!
Baint Prush it’s not the table. It’s a wood board inside a large plastic tub
Such dissolve.
Much wow
great as always
oh thank god.first time I have seen u play with mercury with gloves on!
GJ!
Mercury does not dissolve gold that quickly the amalgamation process slows down alot towards the end of the process ive had a gram of gold dissolving in mercury for close to five months and its still amalgamating for you to do it in under 5 hours just seems incredibly absurd your video inspired me to do this and now i feel like ive been mis informed
feel free to share your results
how much did this video cost you?
Pretty much nothing, he recovered all the gold and mercury at the end, only the nitric acid and zinc were wasted. (The gold was expensive, but has been used several times and can easily be resold.)
KraineK xDDD karambitch (read in a low, DEEEEEEP voice) TWELVVVVE MIIIIIIIIILLION DOLLERS!

doctor what you must be fun at party's.
doctor what have you ever heard of something called a joke? Because that comment might be something called that. Search a dictionary for it.
doctor what your the kind of guy who thinks he is smart but is really unsociable and stupid
his right guys its 1st not 1nd idots learn to writee
extact humor from the comment section
you can't extract something from a place that doesn't have it
Dude I like your videos :3
finally a video thats not a vacuum chamber video...
gona give you a like
Maybe extract iron from blood! if it's possible ;)
And not YOUR blood! I know what you can do for science...
why not his blood? That would make it more interesting
Lucas G. Because he'll have to extract all of his blood just to get about 2 grams of iron and I don't want him to die 😂
He's dealt with micrograms before; if he were to take a standard blood donation volume, boil that down and extract he'd certainly have *something* if only a few grains of the metal.
Can you imagine what boiling blood would smell like!????????

Thanks Cody! This is the first you tube channel I m subscribing... brave guy you are! Previously I have worked on mercury... prepared Mercury sulfide (Black one)... during which I have gone through headache, Throat & eyes irritation and mouth sore... Even after precaution ???
Music at the end was GREAT!!!!
Never knew Mercury dissolves Gold.
It's a typical liquid metal but cooler, it dissolves a lot of things, like aluminum and copper.

How do you store your elements and substances? Very informative and enjoyable videos!
omg you are so close to 1 mil! you should of gotten 1 mil a LONG time ago! best wishes!
you do all the dangerous stuff chemist always wonder and I love it and I love you
Awesome video, Cody! I would love to see you clean up your mercury waste!
Always wondered how you would do that...
Hey Cody. Was watching your old videos about breaking gallium. Could the reason why gallium breaks with very abrupt bending because of the heat that is produced due to friction in the metal melts the metal at the bending point?
What a cool way to find the volume!
