Now that I have your attention. Hi Destin, I love your videos!!!!!

"...this nickel plating machine I happened to have in my garage..."
Yeah, not like an electron microscope, which everyone has one in their garages
@@atropos91 -- I don't have one. May I borrow yours until this weekend? Please and thank you. :)
his science experiment is like an adventure, where he discovers many things in garage along the way
"I wanted to see what they looked like so I put in my electron microscope..."
You can buy plating kits very easily on eBay.
For those out there thinking about doing this: careful with the type of silicone you use for the mould! Some are not safe if you are planning to create moulds for food or diy masks. The one used in the video is a platinum catalyst which is the correct one to use for this.
Maybe JELLO?
You can use PDMS sylgard 184.
Another very good silicone by SmoothOn that is basically made for this task (e.g. making a box mold): MoldStar
COOL!
No shit
8:20 A huge +1 for a video on chocolate tempering and crystal structure! I've seen too many hand-waving explanations, but an actual physical demo would surely be fascinating.
👍👍👍
Yeah!
Looking at crystal structures, tempering, using microscopes; for a food item sounds like a great idea. In other words: metallurgy, but with chocolate. That sounds like the best of multiple worlds. I wonder if Ben will make chocolate alloys at some point...
YES YES YES!
+1 for an exploration of chocolate tempering!
i'm craving for this to happen
So let me start off with, this is brilliant and the results are amazing and you're a fricken genius. I dunno if you ever saw the video on my channel where I'd talked about trying to do exactly this. I even bought literally the exact same holograms from the same ebay supplier. But where I failed was removing the backing layer. I managed once or twice by epoxying the back of the hologram to give me something to grab and physically tear the layers apart but only ever got it to work with an "amorphous" hologram, never the images. I'm stunned it was as easy as soaking it in hydroxide and I'm kicking myself for not thinking of that. I just assumed (apparently incorrectly) that it was impossible so was going to go the hard way of making my own holograms just to have the exposed surface so I could then plate it and make my metal stamp, but now I see there's no point. This is way easier. And of course you took the concept much further than I'd ever have imagined and made the metal stamps which I'm stunned work so well. I still have all the stuff so I'm 100% going to have to try this.
Wow! I must have missed that part. I remember your gecko tape videos -- was that where you mentioned it? I'd be stoked to see your video on making original holograms too. I think a lot has changed since the HeNe sandbox optical table days in the 1990's. BTW, the neural net interface chip is coming along (well, actually, I took a little break from it, but am ready to proceed :) Let me know your sched regarding this.
@@AppliedScience It was in the magnetic levitation table video. I was making that table because I was working up to the holograms and I talk about my attempts at chocolate holograms at the beginning. I'd been putting off the second part of that video where I actually make the holograms because I wanted to buy a nice piece of optical breadboard to use as the actual table base both for the weight but also for the nice mounting holes. I think I'm gonna try your method with one of the really big holograms I have left from that project. I got a rose that blooms as you tilt the hologram, it's stunning. I want to make it out of chocolate to put on top of a cake. I think it's about time I get around to the hologram stuff, just finishing up 3 bio projects I've been working on, then will get back to the physics stuff.
I'll dm you about the chips!
@@AppliedScience Are you ever going to post an update to the geko tape?
Wow my favorite channels conversing!!
@@thethoughtemporium You might be able to skip making a silicone mold to get a large hologram. If the outside edges of the chocolate are freezing first and causing the center to rise slightly while it's still pliable that would leave a pattern on the edges but the center would melt smooth again, which is what seems to be happening. You may be able to freeze it before larger distortion has a chance to happen by, say, dumping liquid nitrogen on top, (that would also press the center down into the pattern as an added bonus). The thinner the chocolate the faster the bottom will freeze and the less likely it will curl or distort. (Once I get my cryocooler liquid cooled I'll try this myself to validate the process. Oh also, could one directly melt something like wood's metal into the pattern to bypass the nickel plating step for making a master as well?)
Finally chocolate bar makers can prevent cheap counterfeits!
Next up on Applied Science : White Chocolate UV thread.
lol omg :D Next up: Swiss manufactured hologram chocolate...

You have 1 reply, but I can't see it? 🤔
a little note here: the tempering process is ruined, but the chocolate is still reusable, just restart
"dedicated video on making original holograms" --> aw yiss
I've been interested in holograms for a long time (since I was a kid when I made my first one). I'm surprised that I haven't done a video about it yet, so it will be a doozy with lots of interesting stuff put together.
@@AppliedScience Please?
Pretty please?
@@AppliedScience you mean back when they were -cool- vintage? jokes aside, yes please!
@@AppliedScience There used to be an amazingly detailed, 45 minute video featuring Swann Rack describing how he made his own DCG glass plates at home on CZcams. I think it was on Daily Tips channel but it's sadly gone.
A transcript of the video lives on on this site: www.allreadable.com/2428KxGU
You can see some of Swann Rack's work on his own channel: czcams.com/video/OQlbsenykyI/video.html
I was fortunate to make some holograms with Inaki Beguiristain who is a modern master of this obscure art and science.
Your chocolate holography is great, btw. I like the way you show how much perseverance it takes!
I remember in metallurgy/metallography class talking about how tricky chocolate would be to analyze using the standard polishing method since it's so soft and melts easily. Would ve interested to see how you might tackle this challenge!
Yes, exactly. Another difficulty is finding a solution to differentially etch the chocolate to show the crystal boundaries. I poked around with it a while ago, but never got anywhere. It seems like it should be possible though.
Luquid nitrogen?
Just to toughen the thing for polishing, sandin paper under it
I would love to see a video on chocolate tempering! A lot of the food-focused tempering resources online rely on hand-wavy black magic explanations of what's happening when tempering or why certain steps work.
I'm particularly interested in what's going on in tempered but still liquid chocolate: what fraction of the cocoa butter is crystallized, how big are the crystals, what's the mix of different crystal types, etc.
Tempering chocolate IS black magic. Understanding the science behind it doesn't stop it being magic ;)
I second this! Ben, _please_ do this.
@@DancingRain absolutely
Try Sous Vide as a method to temper chocolate. Easily controlled, just don’t get water in the chocolate
@@adamtucker7736 Do you have a source to recommend? I've tried both the Serious Eats and ChefSteps methods and find them to be pretty fiddly. Massaging the bag doesn't seem like enough agitation, and the ChefSteps method requires you to get in and out of the bag several times to seed.
A Holo Taco of chocolate! 🌮
Looking forward to a Simply Nailogical video on this.
Poor Claire, she can't even temper chocolate :
LOL! This thought came up for me too.
I found it much more difficult to deal with the chocolate than to deal with the holograms or silicone molding. No joke! It's really touchy stuff -- one drop of water, or one degree over temperature ruins the whole thing.
@@AppliedScience Oh yeah, working with chocolate is quite the challenge
Let's just get Brad on here and see what kind of "alive" shop organisms he can come up with...
@@AppliedScience To make the tempering easier, you could use a sous-vide cooker. Alex French Guy Cooking did a video on it.
The only channel on CZcams that starts by telling you the results and showing you the end within the first ten seconds. *Even the channels we love like practical engineering and especially tech ingredients do scummy sleazy clickbait intros and titles and thumbnails* . Ben is the only one who refuses and makes you stick around by sheer awe and respect ❤️
Nobody tell the Nailogicals or Claire fromthebonappetittestkitchen
Or we could tell them and have some QUALITY quarantine content :P
They have to know!!
Collaboration!!!!
...and the eatable DVD was born.
This idea died even before the first clogged DVD drive arrived at the local electronic recycling center.
Still watching the video, but I'll be disappointed if he doesn't eat at least 1 hologram :)
Now that's my kind of science: snappy, obscure yet flashy, but most importantly delicious!
Would love to hear more on tempeing, whether it's chocolate or metal or conductive metalized chocolate!
You just gave me an idea! Gold-plated holographic chocolate! It doesnt get much more flashy than that!
I wonder if one could sputter gold onto chocolate, and maybe even do so while preserving an existing hologram.
This isn't science! This is engineering!!
@@bielanski2493 Engineering and science are not mutually exclusive.
Chocolate companies should contact this guy. Kids would love these things.
I feel like a chaos goblin for sending this video to Simplynailogical, but I regret nothing. This is such a cool technique!
She needs to see this!
This is exactly the kind of thing Cristine needs to see!
I was reading the comments to see if anyone had tagged her yet 😂
Oh, yes +1 for a chocolate tempering and crystal phases video! That would be incredible!
I've been trying to crack a good way to make holographic edible designs for a minute, and although I don't know if I'll be able to pull this one off, it's so super helpful to understand what makes it happen!
I used to work for a hologram manf in the mid 90s as an electroformer. The man in the hologram of that book was one of the sales man and I worked with some of the peopel who made the holograms that are on the visa and mastercards. As an electroformer I would make masters of the hologram and "shims" as they called them for printing holographic labels, baseball cards, the stickers on the motorola startac batteries... This process is called electroforming. We would receive the hologram made in photoresist on a piece of glass. It was explained to me that the laser would etch an interference pattern into the photoresist and the apsect ratio of the grove is what created the holographic image. We would placed in an acrylic jigand hold it in place with tape on the edges. We would paint conductive paint over the tape and on the jig to an electric screw terminal.We would coat the hologram and jig in the silver solution except we sprayed it on. We would put this in a tank of nickel sulfamate solution as a cathode in a soft nickle plating process. We used soft nickle plating which gave a dull gray finish on the back of the shims instead of a hard shinny nickle platting that is normally used in nickle plating things. I believe it had to do with tensile strength. I don't recall exactly. We would plate it for many hours to get a few hundred microns thick. We would start a a low current and as more nickle built up on the holgram we could increase the current since is was now a bigger conductor which would speed up the process of plating the "silver master" I think we called it. When it was thick enough we would peel the nickle plate off the hologram and have a negative which I think was also refereed to as a negative mother since it had a negative image. We would cleanup the "mother" and smooth any sharp spots on the face of the nickle plate. We would spray the silver master /negative mother with I think it was potassium dichromate. These chemicals were all sprayed in a ventilated hood while we wore respirators. This chemical would allow us to plate the face of the negative master and peel new layer of nickle off to get what I think they called a positive father. We did this many times depending on the number of nickle tanks that were free to make positive copies of them. We did this process for creating negatives and positives from the negatives . It was very critical in this plating process not to get contaminates especially greasy ones on holographic images on the plates. handling the plates just on the edges with bare hands could ruin them due to the grease from our hands to run off and across the plat. Even if I handled something in the spray booth with my bare hands and then sprayed water onto the plate, would cause the over-spray to bounce off the object I handled and take the grease with it and to the plate and ruin it. This is why spraying a release on your hologram was a bad idea. We used the cleaner "simple green" to try to remedy problems . It worked best but didn't always work The final shims I don't recall if they were positive or negative but they needed to be exactly 100 microns thick and the thickness over the whole shim had to be within a certain tolerance that I cant remember, but we had to use strategies of moving the nickle anodes around to make sure it plated evenly across the surface.They would take the shims and form them into a cylinder, I was not part of this process so I don't know it well. They would take a solid metal "roller" that was part of the machine that printed the holograms and submerge it in liquid nitrogen to shrink it and slide the cylinder made of shims over the roller to make a fiction fit. I think they ran a UV setting plastic film trough the machine which would set into the holographic shims to be the holographic product ..label...sticker... I thought you would like an explanation of the process from someone who has done it before. One suggestion I would like to make is that I heard if you put butter in chocolate is hardens shiny, maybe you will get better results
Chocolatiers here in Switzerland do that and I always wondered how they do it!
I couldn't help but notice: the process of going from a plastic master to a nickel mold is a lot like compact disc manufacturing in reverse.
it is called electroforming. I believe they do that for vinyl records too
A chocolate CD?
Mr Lawson my first thought was that it couldn’t play back, that the tensile strength of chocolate is too low, it would fly apart as soon as it spun up in the CD player. Doing some math, CDs spin at 500rpm when reading the inner track, 12cm diameter CD has a velocity of 3m/s (6.7mph) along the outside edge, for a centripetal acceleration of 75m/s^2, more than 7.6 times the pull of earth’s gravity. Intuition tells me that chocolate cannot possibly hold up to that stress, but a quick web search shows some research into tensile strength of dark chocolate and values seem to be around 1MPa, so perhaps it could work...
@@jpe1 Would the laser ruin the track? I don't know how much heat would be applied through it. I'd expect they'd go for as little as possible, but might still be too much. Maybe chocolate is the secret to a one time read disk. Easily disposed of in tight situations (just eat it lol). Secret agent seen eating pounds of chocolate in back alley 😆
@@jpe1 it sort of works and was fun to test out, but it wasn't perfect and was ruined after one play
"this nickel plating machine I happened to have in my garage"
Yep, who does not?
This is so awesome! My sister recently sent me a Twitter pic of someone that'd done this and it blew her mind. I'd seen it before and told her how it was done, but so cool to see you do this so soon after that!
I would LOVE to see the different crystal states of chocolate if possible. I think it's fascinating.
omfg this is amazing, it's mindblowing how all the techniques and science that you literally applied for this project, this is amazing and i love it
For an additional, even easier and very effective method of tempering chocolate, look up "cocoa butter silk"! With the silk, you only have to melt the chocolate, let it cool to a certain temperature, add the silk, mix until incorporated and it's tempered! I do this regularly with my home chocolate batches.
Sweet video! :) I see quarantine is good for Applied Science video frequency... nice job as always!
This might actually be the best channel on CZcams, along with Cody'sLab of course. Thank you, Ben.
Holograms on Chocolate... Incredible, high quality Holograms on Chocolate.. made at home. This world needs more people like you.
The silver plating reaction is called the tollens test, and was used to show the presence of aldehydes in solution. In this case, the aldehydes are the linear form on glucose that are formed when sugar is dissolved in water :)
Everyone: Wow, hologram on chocolate? so cool!
Me: but can I eat it?
This involves stuff I have like from three of my favorite channels. I couldn;t be more stoked. Thanks Ben!
This was super cool! And I'd love to see a video on chocolate tempering, sounds super interesting.
I love how these videos go from zero to a hundred so quickly. One second you're talking about making a silicone mold to pour chocolate into then next thing you know you're analyzing custom made electroplated dies with an electron microscope, all in your garage. Just awesome man!
You could use a sous vide machine to make the chocolate tempering very easy.
Great idea :) It looks very counterintuitive and is amazing, that chocolate can be shaped that accurately
Thats just awesowe! At first i thought that you will print holograms directly on chocolate like on any other surface which would be pretty complicated. But when i saw the method you use, i thought that this simplicity is just ingenious!
Thanks for another fantastic video!
Dont tell Claire about this....
tempered holographic chocolate. I'd love to see her break down trying. uh, wait, I didn't mean it like that...
this channel will be saved permanently in CZcams history in the future ...the value per minute of our time is rediculous ... and is for free ..just wow and Thank You :)
HOW?!? How?!!! How has this man NOT yet ushered in the technological singularity on sheer cleverness alone?
More Tech ingredients & Applied Science collaboration..
PLEASE do the chocolate tempering crystal video - that sounds fascinating
Awesome video Ben! This channel is well spent Patreon money in my opinion. I learn crazy interesting stuff from every video you put out. Happy to support your efforts. 🤙
That was super neat & looks like something pretty fun to try out. Heck, looks relatively safe enough to let older kids try out.
lol, Chocolate tempering. (looks at Claire from BA)
This is Sufficiently Advanced Technology
It absolutely blows my mind that something as viscous as tempered chocolate or silicone is capable of overcoming the surface tension necessary to get into the diffraction grating. Genuinely would not have believed this was possible before a video like this!
How on earth do you get to think of all that awesome stuff? Better vantablack, camera lenses, now holograms (?) on chocolate (???) I am speechless after each and every video, great work!
I love how The Thought Emporium was inspired by you to make gekko tape and in turn he inspired you to make Holo-chocolate and added a bonus in the video. You guys are great.
Edit: Tech Ingredients needs credit for initially popularizing the idea.
Does this mean we can make chocolate CD and DVDs?
omg. Watch out sor the Swiss special services.
Seriously this is my favorite channel on youtube now, my love of food an science is complete🤤
Definitely in for the tempered chocolate video!! Amazing work as always!
Cadbury: *WRITE THAT DOWN WRITE THAT DOWN*
"sorta clear". Imean, it's accurate
Ahahah
I learn so much from this channel I wouldn't have otherwise.
Wow. So many cool ideas and techniques used in one video. That's kind of the meta theme of this channel though huh?
Ah! what a cool topic! When I first saw Tech Ingredients video on the subject, I wondered if you had any ideas on how to improve the process. I also found The Thought Emporiums videos on silicone molding diffraction gratings to make gecko tape equally interesting (czcams.com/video/vpTX32KdVBQ/video.html). It would be amazing to see some sort of holographic collaboration sometime!
I am pretty sure that our host did the gecko tape molding thing a few years before Thought Emporium. czcams.com/video/9XQfYKYO380/video.html
If you do the chocolate tempering video, I wonder if Alex French Guy Cooking would be interested in a collab--he did a good video on chocolate tempering a while back.
You never fail to surprise and inspire. Such a variety, and all epic.
You never seize to amaze me with the breadth of the things that you take on and manage. Well done indeed. Such a wealth of information from you and always presented in a near mesmerizing manner. Keep it up, I for one am grateful for your videos.
sorta-clear-40, it sorta works.
👍🤣 How about a collaboration with "This Old Tony" to make a diffraction grating ruling engine, for other kinds of candy....? 🤔
Add holograms on chocolate to the huge list of things I would have never thought of. But hey, at least now I understand how holograms work.. At least superficially. No doubt it'll come in handy. Cool experiments as usual, Ben!
your videos never cease to amaze me. Are you really saying no one has patented a die that can stamp holograms on any plastic ? If they have not - get in there - that is really impressive. I can see many consumer items with hologram stamped plastic molds.
It makes me cheer every time I see an Applied Science video because the topics are so fricken intriguing!
I can never guess the next video but it's always interesting!
I love the shoutout to Tech Ingredients too
Wow, amazing! Love the video as always and will have to try your metal process! I found an effective way to remove chocolate without affecting the surface texture was to use a layered mold (laser cut acrylic) where the diffraction grating/bottom and the tops would be pulled away from both sides, then you can easily pop it out from the non-textured side and easy to clean, as well as quickly laser cut diff designs for the middle layer (or adjust the thickness with multiple layers). Model/output seen here: twitter.com/samykamkar/status/1259720942470656000
Its amazing how you mix metric and imperial sometimes in one sentence. Tells us (or makes us suspect at least) that you are capable of using both.
Isn’t everyone?
I've always admired the thoroughness. all the trials successes and fails are fairly documented. Gotta Say, Ben share's therotical sciences and makes them practical. There must be numerous start ups using or have benefitted from the open format science experiments Ben has shared. A big thank you Ben. Good work. Good Science and Good Soul. Thank you.
Isn't this similar to how blue butterflies produce their blue "color" ?
I think so!
Its all down to the refraction of light.
@@JeffShepherdphotos Yes, it is a similar and related mechanism that explains the colour in butterflies' wings and in hummingbirds, but it is not quite due to refraction. It is rather reflection, and selective absorption. In this case, we have a diffraction grating that has a microscopic pattern and creates an image. In the case of butterfly wings, you have a series of layers (like scales) one on top of another. Because these layers are so thin, they are of about the same size as light itself, and this makes it so that if the size of the light just matches up with the size of the layers, the light gets amplified and reflected. If they don't match up exactly, the light wave gets absorbed by the material. So, the layers are the size of about blue light, so this light gets reflected. This is the principle of an area of study called "photonic crystals".
@@guillermoalejandroperezlob5208 Yes, very true. A bit like like a DVD
Mars Inc.: Yea we actually invented this quite some time ago, we have no interest in it.
Mutes phone...
Mars Inc.: Get somebody on this right away! I want a holographic logo on every candy bar we make!
it woulnt work tough, any minor melting would ruin it
@@khhnator good point... Well, it could be a quality guarantee at the sametime... maybe for those more higher priced chocolates lol..
but any chocolate covered ice cream would work :D
Lithophanes in white chocolate are also cool but the holograms takes it up to the next level. Nice attention to detail as always and love your skillset as a chemist, physicist and engineer.
I've seen this on twitter, and I'm glad someone made a video on it explaining how to do it.
I would love to see a chocolate tempering.
Check out the videos for Hercules Candy, they have some on chocolate tempering.
I would very much like to see the science on tempered chocolate.
Hah, this was such a timely video since lately I've been splitting apart CDs to get to their diffraction grating and casting plastic onto the diffraction grating to transfer the effect over. Thanks for sharing these techniques that will help me with my own ventures
The plastic holo stamp. The silver nitrate trick. Such cool.

Doesnt everyone?
A few months ago, it was pretty popular to use those diffraction grating sheets as a bed on your 3d printer. You end up with a neat reflective surface finish on your base-layer. I'd wager those same sheets would work well as a starting point for doing this with chocolate
I've been waitíng for this video since I saw the Tech Ingredients video about holographic chocolate. Now I need to make some of myself!
Melting hologram chocolate.

Very cool to see the action on the most delicious material available!
Jeezus, Ben... the pure variety to your videos is amazing. There is no real progression, just boom, here is simething out of left field. Holograms on Chocolate. Wow
First holographic images I will make is of more chocolate bars. 🤗
I could have sworn I'd seen this video already
[EDIT: Oohhh right, I'm thinking of the Tech Ingredients video -- nvm]
[EDIT2: Cool -- this is a nice iteration on the ideas presented in that video. Do you have any clue as to how feasible it would be for someone to imprint their own designs? Do you need lasers or something to make these?]
Tempering is indeed a very important part of making a chocolate.
It allows a homogeneous bar, prevents "fat bloom" (fat making its way onto the surface), smooth surfaces and, most practical of all, easy separation from the mold.
This is complimented with a shaking phase so the chocolate can fill up any space in the mold.
I wonder if the 10 micron grooves you're seeing are a product of manufacture, like perhaps a lathe used to surface the blank that make the stickers
Do I see a NileRed beaker there?
The easiest method to temper chocolate is called cocoa butter silk. Just melt the chocolate and add 2% by weight of cocoa butter silk finely grated to your chocolate and mix. Then just pour into molds. Cocoa butter silk is made from cocoa butter maintained at 92.5°F/33.6°C for 24 hours in water by a sous vide heater/pump ($100). It maximizes the V crystal and provides a seeding or scaffolding for the cocoa butter in the chocolate. No worries about the chocolate tempering curves. It is a DIY "mycryo" micro cocoa butter powder used commercially. Cocoa butter is polymorphic and is capable of forming 6 different crystals. Cocoa butter is a triglyceride (3 fatty acids) and is surprisingly resistant to oxidation with a long shelf life unlike other triglycerides. On a side note, there was a research paper a few years ago where palm oil was used to desalinate water by changing the phases from liquid to solid- it surprised the chemists - not very efficient though. You could probably obtain desalination with the cocoa butter as well - Ben could be the first to do it and measure the efficiency. If crystallization rocks your world, take a listen to Dr. Rupert Sheldrake, a chemist talks about melting points and how they are not constant as you would think due to his proposed morphic resonance theory - quite interesting.
Tech Ingredients VS Applied Science Holographic chocolate showdown.
Man, i forgot all about holograms. Everything in the 80s/90s had them when i was a kid. The polymer ones are stunning, sadly i think i destroyed all mine trying to figure out how they worked! Awesome video Ben.
the coolest thing about them is just how weirdly simple they are.
Cool that you did this! Very comprehensive.
I went with sugar following Tech Ingredients video, and after figuring out the process got some pretty decent results!
I encourage anyone to try making diffractive chocolate or sugar, the resulting color vibrancy is a sight that you can only appreciate yourself, and given you did it by yourself its a very rewarding experience!
The major downside was the moisture in the air destroying the fine structures within about 20 minutes, so I tried it with candle wax, and that worked better than expected.
It did have a shrinking problem tho, and was even more sensitive to what temperature you'd peel off the mold. Smaller pours about 2cm diameter were mostly fine.
What I wanted to try out was pouring into a cylinder, to essentially have a decorative candle with a diffraction grating. That really became a challenge with Temperature control, and didn't produce any viable results due to shrinking issues.
Your silicone molds might work very well for that tho!
Have you tried to preserve the structure on chocolate with some coating? That's something I wanted to look into for the wax, so that they outlast a Summer cycle. But I don't know enough about optics and solubility to figure out which one i could use, so maybe that's something to revisit another winter. I did spend a lot of time getting the process right, so I'm burned out on the wax (heh) for now.
I will upload the video of my most vibrant pour to my channel, but due to phone camera it serves more as a personal memento.
By the time I got the process right the diffractive film got pretty warped, which made the result look interesting and got me thinking about 3d shapes.
woah that's a change of things. I LOVE this. Wonder how long this will take until big choclate companies pick up on it.
Wow - so interesting. I love seeing you break the magic down into something we can understand.
Casually says "I happened to have a nickel plating kit in my garage". I absolutely love it
