Making Grey Tin (tin pest)
I take some metallic (white) tin, cool it off, and it converted to the grey allotrope.

Is it possible to use tin powder for stannous Chloride solution?
The most interesting thing I did for high school science was do the red cabbage pH test. I would have done anything for an actual experiment, not just lighting soap bubbles on fire like I'm 10
dashie approves of the little saying on the wall in the intro.
This is pretty interesting. I put a glass ampule containing 10 grams of 99.99% tin in the freezer many years ago, it took only a year or so to completely turn into powder. Then I left it untouched, until I saw this video. From what I can tell, it's now an even finer powder than what I remember it to be. I guess the transition was still ongoing in the past few years when I'm not watching.
It's like mercury if mercury could mercury mercury.
Kim Jong Un owns the same know how about iron. The reaction is fast and not stoppable. And he will spray it over San Diego.
Of course nothing bad will happen. The Navy must just remelt the destroyed ships to get steel ingots again. So, no problem.
He's wearing a gravity falls shirt. You have good taste.
Oh my lawd I just looked at the sub count and I was expecting like 200k because the last time I looked at it was at like 5k, but 1.88mil? Congratulations Cody! I now feel old tho.
My sample of tin is finally transforming....4 years later.
electronics nightmare
perfect opportunity missed at 4:20 to say "tingot"
Tjin
I have another idea on how to make a metallic tin powder: take a piece of tin, apply a file, and voilá you have tin powder!
2020 anybody?
He's so young. But it was only 3 years ago

Nice
Make a peltier cooler. You can thereby go really low temp. Tjek it out on youtube. And thereby make your gray stuf in no time
Is it possible to make larger crystals of grey tin? Could it be crystallized from something like mercury or would it just crystallize as white tin?
so did the grey tin turn back into white tin in room temperature eventually?
5:40 Mr. Stark, I don't feel so good...
“Here on Cody’s Lab, we now learn how heroine is made and what it feels like. “ *TURNS INTO A VSAUCE VIDEO*
I just read in the german Wikipedia that tin pest occurs "under 15°C". To transform diamond into graphite you have to heat it. Is it possible that you have to keep the tin as warm as possible under 15°C? 'Activation energy'
Stainless doesn't contaminate the tin?
"So here it is, my little baggie of product." *BANG* *BANG* *BANG* FBI OPEN UP
I love your enthusiasm for your experiments. You make me wish I paid more attention in chemistry
My section is tin haha
he's. wearing. a. Gravity. Falls. Tee. shirt. AAAAAAAAAAAAAAAAAAAAAAAAAAA
Eh... I made a little thing in copper and something to solder on it (I don’t remember). That thing has been outside for years (exposed to everything) and when I took it inside and cleaned it the tin that still was left was grey... I accidentally made tin pest
Just like gallium solidifying. If u put 1 tiny drop of gallium in cold water, it wouldn’t solidify till it touches solid gallium
Damn it... I forgot how to be awesome.. Thanks for the reminder Cody!
Gravity Falls!
Hey look at me I’m mr. Meseeks!
Hey Einstein, figure out a way to a new invention or process. make millions instead of living in your parents basement! lol
I seriously wish that I had your skill set. I envy you, Cody! :)
and when i tried to melt it, it turned into dust and just became what you saw here....
i can never get past the foamy tin area to the nice metalic branches of tin -_-' probably coz i have used a 6v battery instead of a dc power source...
if i could live on a rock next to a potato... i don't know how I'd feel about my life, honestly.
ah i see you enjoy gravity falls as well
the spread of the grey tin into the white tin looks like the growth of some horrific disease.
Lol you have the same exact toaster as me.
That moment when you notice his gravity falls shirt
"A piece of tin I had made in my high school chemistry class..." See now if my classes were like that instead of just balancing equations endlessly, perhaps I would have enjoyed it. Maybe then it would be ME flushing mercury down toilets and eating indium cookies.
Cody has an exit sign in his house😂
I like his shirt
Whoa! You used electrolysis in your chemistry class?
cool
Cody, you realize that when someone finds a spoon lying around your place with burn marks on it, they're not going to believe you when you say you were using it to melt tin, right?
Well if got an experiment for you: take tin add grey tin and put it into a Vakuum Chamber. Maybe it would be turning fast into grey tin. Because it seams like the tin would be pressure sensitive as well
So beautiful! Thanks.
takes him 5 years to make, changes it back. classic cody
I opened a corsair flash traveler usb key and i was asking myself what is the grey residue falling!! I know now!! BTW the key still working but the pcb is loose from the frame, i was to resolder this.
I got a 50 second unskippable ad for legal steroids before the video wtf
Cody must be one of the few who uses water distiller for distilling water.
Hey cody is that the clothes from gravity falls
How bout a short circuit control box that could be used on head phones
Can I get an explanation of allotropes? I know a bit about white, red and black phosphorus and now gray tin, but I don't know how they actually work.
If only Napoleon's had taken as long as you did to make tin pest (with your zinc or iron contamination)... they might have managed to invade Russia. :/ (oh... I got that from Arthur's video!!! Don't sound as clever as I thought now, do I?)
gravity fallss shirt nice
you named your little ingot Cody Slab, thats adorable. xD
Please don't record in that room with that mic again. Need lavaliere mic
Try to mix gold platinum and silver to make a astroid
Why is it that, much more than the cold temperature, the presence of "grey tin" aided so strongly in making more of it? It almost seems "disease-like," and I assume that's where the name "tin pest" comes from?! Are there any other applications for this besides your stannous solution? Do you have a use for it, or was it more curiosity that drove you? Thanks Cody .. I don't have a physics or chemistry background, but your videos are really interesting for laypeople! Cheers!
Is the mentioned stanis? Cloride the same as tincloride?
After watching your videos for a few months I've actually got very interested in chemistry and I can't wait for a chemistry class. I love your vodd
Vids
So it's kinda the tin version of (fictional) ice-nine?
You know who wouldn't approve of this video? Puritans. I'll see myself out
The internet lied to me! Grey tin doesnt happen quickly, I just misplaced the tin in my shed.
I love Nile reds videos Yes this is Cody’s lab Still I like his videos and mentioned
Makes his own tin. Buys distilled water at a grocery store. BTW How does this compare to zinc pest and do you know some way to stop it?
Cody made a special product and melted it in a spoon
Clickbait title: IT TOOK ME FIVE YEARS TO MAKE... THIS???
what's the electricall properties of this form of tin? can it be a semiconductor?
no it says cody slab
Interesting....years ago I seem to remember someone telling me a story about during the war, the Nazi's pursued the Russian's back north, and as it got cold, the shiny tin buttons on the Nazi's uniforms 'turned to powder' and they couldn't keep their coat's closed, so they all froze and had to give up (something like that). I was told 'tin turns to powder at really cold temperatures'. I think I might actually have a much better explanation of what happened now :)
Would a grey tin man from the wizard of oz be similar to a zombie
Loving that gravity falls tshirt
love it, thanks for the inspiration!
I'd love to see a video on the formation of tin whiskers.
So would you have a endless source of tin for stannous chloride?
Are you the stannis chloride in that jar? Cause You're a tin.
I wonder if it is possible to make a large chunk of grey tin without it crumbling.

Tin feathers that’s so beautiful
Cool stuff!
What is the significance of the gray tin???
Hi Cody, i just graduated collage and i've started my first real engineering job. I was recently educated by the head of engineering that we can't produce ROHS compliant boards because of the threat of forming a "tin whisker". Is the formation of a tin whisker at room temperature just another means of forming the allotrope grey tin?
No tin whiskers are a different phenomena. There isn't a fully agreed on reason for tin whiskers but the most common answer is from the residual stress in the solder joint causing the tin grains to extrude out of the surface when they form certain favorable grain boundary angles with the surface. So most of the methods for mitigating have to do with removing residual stress or alloying to change the grain boundary angles or flow stress of the grains.
FNORD!
what is the purpose of gray tin though?
Hey a gravity falls shirt!
What other experiments did you have in your freezer?
All i heard is reality is an illusion, the universe is a hologram and buy Gold
cody slab? apparently its tin slab
Cody Slab xD, such a great mark for a chunk of metal
I also made grey tin in my freezer. My starting material was metallic tin from Rotometals. There seems to be a lot of questions about how pure the tin needs to be for this experiment to work but I found the Rotometals tin sufficient. It also took several years for mine to convert. I had no idea that you could "seed" the conversion with a bit of grey tin. That is very interesting!
That Bill Cypher shirt! Woo!! Cody is a Gravity Falls fan!
Yeah suuuuuure that bag of product is just "Tin".... lol
Here's some notes from an old chemistry book: "The transition point can be detected dilatometrically and lies at 18°-20°. A mixture of the two kinds of tin neither contracts nor expands at this temperature, while at higher temperatures a contraction is observed and an expansion takes place on cooling, due to the disappearance of the grey tin on heating and of the white tin on cooling. The same transition point is found if electrodes of grey and white tin are placed in a solution of a tin salt and the resulting potential difference followed. At about 20° this is zero, but below this temperature white tin, and above it the grey variety, has the greatest solution pressure [i.e. EMF]. As the ordinary temperature in temperate climates is usually below 20° it follows that all tin is in the metastable condition except on a few very warm days; and it is only because the rate of transformation is so slow that the tin remains unaltered on most occasions. This pseudo-stability disappears at once if the tin is placed in a solution of a tin salt. The deposition of tin takes place owing to the small currents set up by differences in concentration in the solution, and the tin is naturally deposited in the form stable at the temperature of the experiment. The small amount of grey tin which separates out at temperatures below 18° is enough to infect the whole mass of tin. The rate of transformation is thus markedly affected by the presence of tin salts, and whereas dry tin shows a maximum rate of change at -48°, when immersed in a solution of a tin salt the change is most rapid at 0°. The previous history of the tin also affects the rate of transformation, and a sample which has been undercooled for a long time is converted into the grey form much more rapidly than tin which has not undergone this treatment. Again if some grey tin is transformed into white and then back again into grey, the second change takes place more quickly than with fresh tin, and the more often the tin has been transformed the more rapidly the change takes place. Even the transition temperature is affected by a repetition of experiments or by intermediate heat treatment; with cadmium it can be depressed from 70° to 62°." (Temperatures are degrees Celsius.)
