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!

My friend told me that he made Lithium react with Argon. LiAr!

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.

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

Cody, stop using your great grandmother's decorative plates for science.

Who else learns more from Cody than their science teacher 😂

Welcome to Cody'sLab home to mercury, mining and vacuum chambers

For some reason I understand you better than my chemistry teacher

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.

How long till Cody finally goes full on Breaking Bad?

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!!

How to make the worlds most expensive chalk.

I'm a simple man, if I see a Codyslab video I press like.

Hey Cody! Just wanted to say your channel is awesome! Some of the stuff you do is amazing... Keep it up!

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.

13:37 long video and +100 likes people know it's going to be a good video.

it looks like chalk, it feels like chalk, but does it write like chalk?

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

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!

3:36 so thaaats how they made candy cigarettes. No wonder its so hard to find nowadays.

Imagine the pain in the ass it would have been to try and recover the gold from the mercury toilet.

this is my favorite channel on youtube. ive been with you since 2500 subs

Thank you for everything Codyslab you're my favorite friggin channel.

Thumbnail was written by a caveman scientist.

You should have named the video 'Making the world's heaviest liquid' with some crazy thumbnail. Do you even clickbait Cody?

Love your videos Cody! I always learn something new!

almost at a million subs! great to watch the channel grow!

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.

Almost at 1mil subs!!!!

So close to a million. I subbed at 36k congratulations!!!!

another trending video! killing it Cody!

SO close to a million subs !!!! LETS GOO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That chalk from the gold and mercury is very interesting.

I'm binging older Cody'sLab videos again and my god, I love these videos so much

Almost to one million subs. Nice. Love your vids.

much dissolve, such wow

I like your outro Cody!

your channel has gotten huge good job

Great Video Cody!

Any updates on the digester?

Current methods for extracting gold from ore require cyanide. Can you make a video demonstrating this process?

Something tells me Cody wants to be rich. Always looking for gold :D

Wow I'm actually impressed by that scale trick to get the volume. Never seen that before, but that impressed me 👌

What happens to a weighing balance in a vacuum??

Wait, I know that 1g of water is 1ml but how does displacing water make it have more mass?

I'm not at all a scientist, but I think all of your videos are so entertaining and interesting! Great job!

Awesome video. Great frequency of content too! Keep going"

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?

You should try to extract metals from a catalytic converter

I love your videos Cody :D

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.

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?

Lol a 33 minutes long advert before this video by Tai Lopez

If Cody and friends were around doing this stuff 200 years ago, we would be on the planet Mars with kids by now.

your knowledge is impressive!

Get a haircut when you hit 1 million, Cody. ;)

How is he measuring the volume with a scale?

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 ???

Cody wakes up in the middle of the night to drink something. Stumble across a bottle filled with liquid, presumes it's water. Drinks it, tastes sweet he says. Goes back to sleep. Wakes up like a mad man going insane!!!!!

I am watching this from an airplane how cool is that

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

Nice video, I always wondered how much gold would dissolve into mercury. And damn, almost a million subs!

love the vids Cody

ALMOST ONE MILLION! LETS GO!

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

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

Nice, I can expect another mercury video within the next few weeks!

how much did this video cost you?

extact humor from the comment section

almost 1,ooo,ooo subs !!!!!! love you cody

One of the few youtubers who regularly does experiments with expensive metals :) Quite interesting!

Mercury on table at 3:49

Such dissolve.

Awesome video dude!

Getting close to a million! Keep it up!

Maybe extract iron from blood! if it's possible ;)

13:37

always interesting, another great video!

oh thank god.first time I have seen u play with mercury with gloves on! GJ!

Useless comment about me not being first!

Never knew Mercury dissolves Gold.

Just love your videos.. Awesome channel

How do you store your elements and substances? Very informative and enjoyable videos!

1nd

I like pie

Awesome video, Cody! I would love to see you clean up your mercury waste! Always wondered how you would do that...

great as always

I know i say this about most of his work.. but man i love the precious metals series

This video is as elite as it's own length.

Man Cody, I love your vids. I've stuck it out with you since the "magnet self-surgery" days and have been captivated since then. I know the topic of this very video is different than what I am asking, but, since you always seem to not get back the return in refined gold, is there an actual point where you, personally, see yourself gaining a profit from this kind of process? Keep up the good work!

very interesting video man, big fan

That density measurement technique totally blew my mind. I thought this should not be possible at all. This really got me wondering what other things I assume to be impossible which actually are quite easy to do... One thing though: Could you add an annotation to the video, linking to the video explaining the method? This should be more convenient for other people who do not know the technique yet :)

I believe some ancient alchemy texts say that bismuth and gold will dissolve more because the gold and bismuth will form Au2Bi a compound. That will likely double the amount of gold you can dissolve. Then you can add that to antimony bronze and then after driving off the mercury a nice alloy will result.

super interesting as always.

almost to 1million subs. congrats

At 20c water is 0.998g/cm³, and data table I have shows mercury at 13.546g/cm³ at same temp, so, some maybe a third of the discrepancy could be chalked up to that, but maybe a more precise weighing rig is in order. After I saw your video about it, I used this method to get density of a supposedly nickel crucible. I was able to get precision of +/- 5/10,000, and results very closely matched published value for Ni. Thanks by the way, I tried before to use displacement like I remembered from school, (measuring overflow water) - not very precise...

Music at the end was GREAT!!!!

I got half way through this thinking "dang he's talking fast, must be excited to be doing this"....I had it on 1.25x speed

Thank you for not pouring the mercury water down the drain, Cody.
