Time to make your own Gold playing card

Wonder if the 'Certificate of Authenticity" was the only card plated in gold...

Cody said the picture of the 100 dollar bill looked ugly right when I was thinking the same thing

Just fyi that hand-held xrf analyzer is like 40 grand. I want one. Those are sweet.

EDIT: *SPOILER ALERT!* Sorry guys, didn't expect this to be at the top of the comments! Well, if it's not gold, at least the cards look really nice, and now we know they're pretty dang resistant, so at least he can keep them for fun! Plus, even though nothing was refined, this really was an interesting video to watch. It's always good to see how to know things aren't going right!

I still wouldn't mind throwing $10-15 at those fakes, if not for the stupid back.

nice video, and you exposed a fake company in the process. I hope someone uses your video to take action against that company if possible. its not right for them to be allowed to trick people into buying that crap even if it was cheap, they still think its real gold.

The mining and refining videos are your best.

I hope the next Cody’s Blab video is of you calling the manufacturer for an explanation, haha.

In the next video: *Puts his arm shoulder deep in a barrel of aquarega" "Is this your card?"

Man Cody, I love watching you think your way through things! Do you think we could get a Basic Chemistry series?

the certificate doesn't have a lab name or a Certificate Authority, where can you verify the number?

This is my favorite series other than the mining series please do more of these

i love your videos beacuase their educational and the refining series is my favorite series of videos!

Omg I was just rewatching this series last night because I love the series so much

Doing a time lapse on a giant clock is a really great idea

Love these gold videos

fiat printed on fake gold. actual meme

Always a fun visit Cody. Thanks a bunch.

Thank you for doing the gold leaf experiment again for the time lapse, shows ya dedicated mate! Keep up the great work!

Cool I'm going back to school at USU Uintah basin for a chemistry degree. You've inspired me Cody

Gold leaf in iodine solution: Mr. Cody, I don't feel so good.

What I appreciate about your videos is that you're not just some kind of gold-crazed prospector, you're genuinely interested in the chemicals and processes over all.

Thank you cody for that video, I appreciated the expert hands on chemistry you did there. As well as the homework, I'll get back to you on that.

alarm bells ring for me when i saw the plastic as not many elements can be plated to plastic and gold is one of them as plastic cant conduct the current needed for electrolisis.

I thought you were going to make gold playing cards for a second and I thought "wow cody is this really the best use of your resources?"

im happy for you that you are getting so many views:) been here for bout 2-3 years. keep it up

honestly this is my favorite series on your channel man.

Wow that is a shitty scam. Time to test the old gold plated pokemon cards from mcd's or bk whatever it was back in the day.

Heck yea! he's back!

Cody, huge fan. You inspired me to start keeping bees this season, and I love your videos about refining -- mainly for the chemistry. I would love to see some videos about how to produce basic chemical reactants from natural or readily available materials. For example, making your own nitric acid, or recovering elemental sulphur from ore, or the iodine from sea kelp. Thanks for the videos!

As an aspiring chemist, I love ypur videos Cody and have been watching for a long time. Another fantastic video.

"For reasons which, are too complicated to explain right now" Basically, he's saying we're all intellectually inferior.

If they wanted to make gold plated cards that you could actually play a game with more than once without destroying them, the gold layer would certainly have to be beneath something. If I had to guess, I'd assume they're using something like PETE, which is the type of plastic soft drink bottles are made of. One of its propertities (which is probably very relevant to being food safe, actually) is that it's pretty innert and most common organic solvents (such as your paint thinner) won't touch it. Even with solvents that DO work (DCM seems to be a common recommendation. More specifically to PET family plastics, phenols, as well as DMSO and nitrobenzene), you will probably have to heat it up close to the solvent's boiling point and then wait a few hours.

These are some of my favorite videos that you do. That and when you actually are in your mine.

I love these precious metal refining videos

What would happen if you burned the cards to see of there were any metals left?

I'm just curious whether you checked that the certificate itself was gold plated? I know that it's a common tactic in the more unscrupulous sects of the leather industry to use a patch of real leather that says that it's real leather as the tag on an artificial leather jacket so that customers think the tag is referring to the whole jacket rather than just the tag itself, and something similar could've occurred here?

Thank you for still showing the true reaction after the cards failed to yield anything. Golds not cheap and I hope you can recover as much as you can. I really love your channels and I hope you never stop doing what you're doing.

always enjoy your vids Cody. nice work

But how it had a certificate of 'Authenticity...' Man I hate scammers... My first concern when it failed to react right away.

Maybe they were copper plated first then a super thin layer of zinc. Zinc plated onto copper is known to actually alloy with it on the surface creating a nice shiny golden brass. Ask nurdrage

Awesome video... Always love your videos Cody. 👍👍

The way the gold dissolved into pitch-black was mind blowing! I'm in awe, with my jaw on the floor

Can you try to extract the mercury from the vapors in a florescent lamp?

How about trying to refine/recover metals from the plants around your mine? Biomining?

I always watch cody'slab no matter what!

I really like how you change intros from video to video - music, video itself, brilliant! :)

What if the certificate of authenticity is the only thing that's actually authentic? Did you test that or only one of the actual cards? That'd be pretty funny, and they wouldn't technically be lying. The certificate only says that there is genuine gold somewhere inside the deck, not that each card genuinely has gold.

The gold leaf dissolving in the iodine: Mr Stark I don't feel too good

thank you for reviving the series

Cody, I always enjoy the science you present. 😊

In bed. Drifting off...*DING* CodysLab. Yeah, I am up now.

Is it possible only the "Certificate of Authenticity" contains gold? Was that included in the x-ray test?

Yes! Cody this video made my day! Thanks man!

Excellent video Cody 👌👍

Iodine, uodine, we all dine for iodine!

Do the road-dust platinum please!

Thanks for doing the time lapse on top of the clock. It showed us how long the reaction actually took.

A wonderful demonstration Master Cody! I've never watched gold leaf dissolve in iodine, that was spectacular! Sorry about the cards, can't wait to see what's next!

YAY, MORE CODY

That was actually really sad to learn. I hope the company that's selling the fraudulent cards is taken down. However, you still managed to make an interesting video out of it! I can't wait for more videos of this series, hopefully with legitimate materials next time. =)

That gold leaf dissolving was beautiful!

Great video! Thanks Cody!!

It might just be all about the wording that is on that guarantee. It might be that the gold that is on it is 24k gold but it doesn't necessarily mean that the entire card is gold plated. what I mean by that is if you look at the crowns on the face cards they are a slightly different colour from the rest of the cards front and backs. I would check those crowns and see if they might be the only gold plated parts on those cards. Ideally thought I would recommend turning the cards to ash, and then treating the ash with a solution of AR and then testing that solution with stannous chloride to see if any precious metals are present. Or if you want to use your XRF just test the ashes prior to treating with AR.

You inspired me to take pre ap chemistry as a sophomore

Thank god this series is back

I loved the last segment with the ticking clock. Got 60 Minutes vibes.

Ooops Cody you left your delivery area in the video

Saw the notification and I was like YEEEEET

I really liked having the clock under the timelapse!

I used to do vehicle wraps and it looks like gold vinyl wrapped over plastic. They make some incredibly metallic and lustrous gold chrome vinyls.

In the beginning the universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

poor ranch

Great video, you sound a little demotivated or tired. I know everyone has struggles and I just want to say that your videos are always high quality and of excellent information and good science. Thank you and please keep doing what you are doing. You are adding scientifically backed up knowledge to the internet and enhancing and advancing anyone who is subscribed to your channel.

cool shot with the time lapse dissolve and mechanical clock

Gold Fail more like it, hehe

Can you do a series where you refine something starting from scratch? Like you take something that needs chemicals to refine but make those chemicals from scratch using only tools and no purchased chemicals aside from water.

I like the use of the clock, it was a good idea.

Awesome! Been waiting for more recovery videos woohoo :)

coincidence that episode 25 involves playing cards, because there are 25 cards in the deck!

Those five dislikes are the people who genuinely believed in the gold cards

It could be alternating thin layers of Al2O3 and SiO2. If you choose transparent layers carefully and alternate them with the right thicknesses you can create coatings with all sorts of optical properties. Metallic looking, colour filters, AR filters etc.

and this is why i love youtube, I enjoy this channel and if cody was my science teacher I might have listened

Wouldn't it make more sense to add the sodium hydroxide before the hydrochloric acid?

Hey Cody, I have a challenge - make the golden playbutton out of actual gold - but the one with the new design (I know, ridiculous, heavy, very expensive) but fun!

The only solid gold cards I know of are from Mitsubishi Materials. They produced several sets of Hello Kitty themed card decks for the 33rd anniversary of Hello Kitty which were made of fine gold rolled several microns thick then covered in plastic. They also produce printed fine gold business cards, which are made of paper roll-coated in one gram of fine gold.

Time for another precious metal refining video

Are the cards heavy

TIL you can buy gold coated playing cards

I love your regular gold refining series, but this was far cooler. doing failure analysis and deductive reasoning within the specific realm of chemistry is greatly interesting. I would love to see you do more episodes on analytical chemistry!

I would like the explanation why it does disolve better, I highly enjoy it when you write down the chemical reactions

Does anyone else genitals buzz a little bit when they see a new codysLab video?

So let me get this right... you add HCl then NaOH and you think that... nevermind.

love the clock in the time laps

I'm a jewelry designer and love these videos ;) thanks for educating us :)

noti squad

last.

I love this! Do more please!

I liked this style of video a lot. I know it would be tough, but this sort of detective kind of work is quite intriguing. Even grabbing a rock sample from the mine and finding the concentration of each mineral in it using this kind of chemical reaction would be very interesting.
