- The "gold penny experiment" seems to be in violation of the laws of physics!!
This experiment is a favorite of chemistry teachers, and there are several videos of the demo online. However, info on how it actually works is nearly impossible to find. In this video, I set out to demystify this awesome reaction once and for all.

It's funny because I learned a lot of chemistry by doing silly experiments like this when I was younger. However, this was one of the only times I was left more confused than when I started. It wasn't until after getting my chemistry degree that I decided to look into it again, and even then I had trouble finding info! However, I finally came across this great paper that covers the experiment in nearly every way possible: pubs.acs.org/doi/10.1021/ed07...
As for why I've been absent on my main channel, I've been in the process of building my new lab and I don't yet have a setup where I can build crazy stuff right now. Most of my tools and parts are packed away in boxes at the moment, and I've been doing construction work nearly nonstop for several months now. The lab is nearly finished though, so a bunch of crazy content will soon be released! Stay tuned!

when he said “it’s free energy” he sounded like a legit supervillain
He should team up with the “Free Real Estate!” guy
Are you implying he *isn't* a legit supervillain?

When does Styropyro not sound like a supervillain...
1:41 I think he’s really just looking for excuses to reuse the “attacking a battery with a sword” clip in as many videos as possible at this point.
I'm fine with that cause that bit is great
Wouldn't you?
I can't blame him in ANY way
styropyro: "How do I show people that a battery wouldn't work?"
styropyro: ahh yes 1:41 should get the message across

@@Nathan-kk6lb it’s a good clip XD It’s got that nice Swing swoosh
this man is a menace
A battery would work if you charged it with separate current but still low amp. Us less battery. I make batteries all the time just by experimenting. If love to meet styro. I bet I could show him some things. As well as he's shown me
Thank god for RUclips's new "most replayed" feature confirming to Styro that we all like to watch batteries get abused.

in terms of meaning it's almost a direct translation as well xD

In original coin it is written 'in God we trust, liberty 2020'
And in his drawing he wrote 'Allah hu Akbar, liberty 2022 '.
As someone who recently graduated with a bachelors in chemistry, this was definitely weird but once you showed/talked about the paper it made total sense, lattice energies are kinda weird to think about sometimes especially when it looked like it was a homogenous layer of zinc that was forming
Well if you are a chemist, what did he say before zinc dust? I’m trying to re do this experiment but I don’t know what he said
@@UltimateBread48 I'm not a chemist but he said "Lye".

Fun fact! Pennies used to be made out of pure copper, then added a thin core zinc in 1962. However, starting in 1982, pennies switched to copper PLATING on a zinc base (97.5% zinc). This means that modern pennies can be turned into brass without bothering with the initial zinc plating! It will, however, produce a slightly duller brass than a plated penny
(Note: be careful not to overheat the penny if trying this. Because zinc has a much lower melting point than copper, it's easy to liquefy the inside of the penny and leave a fragile "shell" of copper. When the copper inevitably breaks or melts, molten zinc will spill everywhere, risking serious injury)
Further notes: The penny actually stopped being fully copper in 1837. From 1837-1857, it was actually a brass alloy of 95% copper and 5% tin and zinc. In 1857 they switched back to copper with a 12% nickel core, and then switched to the now-standard zinc core in 1962, starting with only 5% zinc
In the UK it's similar, except it took us until 1992 to make the change and we chose steel as opposed to zinc for the bulk of the coin. That means you can easily separate old and new copper coins by using a magnet.
Same applies to the 2 pence coin and they were both changed as the value of copper in the coin exceeded the value of the coin.
@@drunkenhobo5039 I worked in a lab with a small MRI magnet and would sometimes stack pennies in a pyramid on their edges sideways (if you can visualize that) when I was bored.
Getting free energy from pennies wouldn't make any cents anyway
When I was in 8th grade, I submitted an electroplating experiment for the end of the year, but my battery and wire setup didn't seem to work after a while, so I gave my teacher the penny in the water & zinc sulfate solution that I had found in an old chemistry set. It sat on his desk for a couple weeks, and one day he pulled the penny out and showed me that somehow, it had ended up plated even without the electrical current XD I think this is exactly what happened!
Now I need to see Cody to do his intro with 03:56
Yes
Take my upvote
For sure
that's exactly what it looks like, xD

I remember the silver pennies being one of the earliest chemistry demos I've seen! Always great to see it again 👍
I don't know much about the subject, but it looks like a neat method to keep in mind when making custom coins, like for LARPing, historical recreation, micronations, etc.
2:30 Yeah, the good old Allahu Akbar penny
real
I got three minutes into this. Then I went and spent my life savings on constructing a free energy penny/zink powered reactor to save humanity and win one of those cool Nobel prizes. I eventually ran out of both pennies and dollars though...
I presume that the "Allahu Akbar" was just a friendly play on "In God We Trust?"
Loved the penny rendering you made, also love the way you get angry at things defying thermodynamics. It's like, why did learn this stuff if it isn't true?! Oh. It is !
1:41 that made me laugh harder than it should have
Same here lol. I just love it whenever he does sudden and random things like that for absolutely no reason.
That's from the video where he was harvesting carbon rods out of batteries lol.
It’s made me realize how much I need a machete.
he and nilered do this so often
@@xthee_0nly_1x11 they are pretty great tools and come in an amazing variety of practical, specialized, and not so practical designs
Good to see you still making content, you're one of my favorites that still exist.
You always do a great job at unveiling the mind.
This was incredibly cool, and I'd take it one step further and say your content is some of the most interesting on this website. thank you.
this is pretty awesome. Found you through YT shorts but enjoy this long content as well!
Check out his main channel if you like his longer videos, he’s got lots of stuff
I did not know that high zinc brass made such a nice silver-grey steel ish product... That gives me a great idea for creating a polished steel- finish on copper plated plastic...
Glad to see a longer form video. Can’t wait to see the new setup!
I just love all your stuff. It’s so fascinating and the information presented finely
i like the idea of short videos that don't fit as full videos on the main channel but are still a bit substantial over on this one! :)
2:25 damn that coin
that **is** pretty cool, dayum, thank you for that wholesome piece of knowledge, love what you do, I constantly learn lots from you
You have just solved a problem I was having with using copper tube and fuel containing nitro-methane. The problem is nitro an copper can be unfriendly in certain situations, so much that I had avoided using it for some small fuel lines. In the meantime I made some out of Stainless. It is way too hard to swage (bulge) the ends easily though so I'm not happy with them either. Now I know this is a thing I can make copper tubes with the bulges on each end easy then turn them into brass that doesn't misbehave with the fuel!
Ahhh, mixing chemistry with RC projects.... that's always a good day.
wouldn't brass also react with the nitro, since it still have copper in there? The zinc in the copper will still turn to brass over time. The heating only make it faster. A better option would be to nickel plate the final copper set up. just a battery and nickel solution would be enough and have as much chemical resistance as stainless steel.
@@TheCuteZombie That is also really good option that I have considered. I use electroless nickel plating solution as it is better at getting into tubes and plating the insides. One reason I haven't done this is I was never really sure how well it coats the insides. That said though, I do have a Mill so I can easily enough plate it in Nickel and then mill it in half and check. I just saw this and it immediately made me think I the issue I had at the time with using copper tubes. I could actually go out and just buy Brass tube. But this can still split when I'm swaging it to flare the ends. Copper is ideal because its nice and soft and flares really well. Long story short, I'm going to try both zinc-ing them and I'll try your suggestion and Nickel plating them then opening them up to check the insides.
@@aSpyIntheHaus the question really is if zinc will protect against nitro. It will inevitable turn to brass due to zin dissolving into copper. The heating, like I said, only make it faster.
I have done this experiment in the past using zinc from batteries, and after a day or two the silver turn to the gold color of brass. That is why i sugest nickel, since it also stick very well to copper (chromated pieces are copper, nickel and chrome plated) and nickel is basically inert to most substances.
@@TheCuteZombie So brass works fine with Nitro fuels. The issue is only with copper and only occurs in really particular situations like if the fuel is left to dry over a long period of time creating a compound which can decompose violently if subjected to shock. So brass doesn't have this issue and its not the zinc coating that I'm chasing it is it converting to brass that I want. I still think I nickel plate them but it was just that I hadn't thought of it at the time. I'm still waiting for my zinc powder to arrive.
I remember NurdRage posting a video on this some years back. Good memories, thank you for posting this!
your content just gets better and better
Every time he asks "Pretty cool, right?" I feel the need to correct him. No, it's not pretty cool. It's REALLY h€cking cool!
huh thats a new format of the vid from this channel.. I like it! its nice to learn something new
Years ago I found a dime that appeared gold, it got me curious and it lead me to finding about things like this, so glad you made a video about it too.
I absolutely love this channel!
He's a cool ass smarty pants. I usually learn something by the end of each video. Very consistent content! 👌🏼✌🏼
Love your channel!
love you posting:)
Brilliant sir! I love your content.
We need more content! Lol always a pleasure
Ive been anoyed by this for years thank you
i hated chemistry because i could never understand it. thanks styro, i've started liking the subject because you do experiments & show the observations first before backing it up with theory. i always hated teacher's throwing a bunch of random reactions at me & expecting me to figure it out :)
Glad to see some shorter videos that aren’t using the shorts player!
Pretty cool. Love ur animated penny lmfao
love your videos
good to know your alive
I really miss your longer videos. 😭
Awesome video brother!!!!🖐️

What if someone does this with tungsten coins? He could fool people into thinking it's gold
It would be pretty expensive to get so many tungsten coins
@@anaveragegigachad39 Still not nearly as expensive as gold, though, only about $300/kg for finished products, vs. $60000/kg for good.
Considering that Tungsten metal is basically always in high demand. You'd have to order Ammonium Paratungstate by the ton overseas, set up a Molybdenum Disilicide heating element vacuum muffle furnace, and develop a method for making the coins from scratch. All just to commit one of the dumbest forms of fraud imaginable.
I'm no expert and I may be overthinking this so correct me if I'm wrong, but I can forsee a few minor teething issues in your scheme; in this fun demonstration the zinc does wander into the surface of the copper/bronze layer of the coin but it doesn't go very deep and it's not exactly a thick layer of brass formed, you can scratch it off fairly easily. Even if you place a tungsten disc inside a thicker body of brass there's also the issue that destructive testing, things like touchstones/abrasive surfaces are used to test for gold, it's alloys and other precious metals by abrading small quantities of powder from the surface of the soft metal/alloy then applying acid of several known concentrations and seeing which react with the powder formed and the brass isn't nearly as soft as gold and the tungsten definately isn't and is gonna resist that abrasion without breaking a sweat, and chemical separation/purification procedures are going to dissolve the zinc alloy and leave behind a few naked pellets of tungsten swimming in the bottom of the container. Also if the mark decides to do the old fashioned test of biting it to deform it they're going to break their teeth which is going to indicate that something isn't quite right.
Even past all that if you can't get pre-made tungsten pellets in the correct dimensions then I don't even want to think about how you'd go about getting the plant to do so and procure the materials without telling the world you're working with tungsten.
I dunno man it's a lot of startup capital and effort to commit fraud in a manner that wouldn't be very well hidden.
tungsten is nowhere near dense enough.
Big props on the 1.134 reading on the multimeter. I don't know how the hELL you got that to work or if it was just coincidence, but it made my day.
That drawn penny was hilarious.
Glad to see you alive drake
This makes me understand alchemy a little bit
Super cool! 👍🏽
love u bro you should make more videos
It was nice knowing ya man. Watch out for Exxon lol
Please never stop making videos
I resonate with this video xD I always found thermodynamics, energy and entropy quite interesting, and I keep on trying to find ways around it, and loopholes against entropy, but of course, I never succeed, *entropy is inevitable.*
Fascinating thanks
upload a video silly guy, we've been waiting
Its good to know that your alive Drake.
Bro u sound so confident is scary
You are so frikin cool and also ty for making wanna do science :)
This is amazing
Imagine doing this in front of someone in like the 1700's
While babbling an incoherent incantation.
I've been wondering about how this works for a long time (coming from just knowing the activity series). Still not sure i get it, but I will watch again 😄
so the driving force is the formation of brass! okay now i think i might got it.
3:43 good.. now electroboom wouldn’t raid your house with Tesla coil tasers
damn this is actually awesome
This is really cool
Actually is a fantastic bit that I would never had really looked any further into than the basic gold penny trick.
oh yey u back
That was awesome!
I love you, please do more
2:26 THE COIN THOUGH
Legitimately awesome
This is awesome
woahhhh alchemy that actually works!! amazing!! are there more alchemy (ish) reactions out there?
If this guy and NileRed did a collab, they’d probably take over the world.
styropyro and ex&f would scare me more
Make more long vids please I miss them you make good content
I swear I get a, "yer a wizard, Harry," every time I watch you
imagine doing this so you can use these "gold" and "silver" pennies alongside the normal copper looking pennies in a DnD LARP
wow, that is really interesting.
Thank you Nile
Wouldn't mind if you did more short form videos likes this
At 2:37 you can see its cursed with "hell" upside down in the multimeter. Lol
Why does this guy look kind of insane? Rocking back and forth, barely blinking and grinning sinisterly.
Never stop making videos
You're just getting back the energy that was put in to start with.
Could be a really fun way to make gold coins for your fantasy campaign
Styro pyro it is indeed pretty cool.
thanks for not uploading this as a youtube shorts short
Lulz at the coin drawing text.
the eye contact from this guy makes me think of scrambled eggs
i still have some coins that i changed the color of about 20 years ago in school lol. that's where my love for chemistry started. too bad i'm awful at chemistry! i can still enjoy it as a hobby though
those coin drawing are bad joke, seriuously
Now I wanna do this
