- I test to see if a fusible alloy can destroy aluminium the way that gallium or mercury does.
I only tested the one alloy (mostly because I didn't have any spare cadmium) but I think anything with tin in it should act similarly.

"It's about 3 nano-lightseconds long."
Never change, Cody.
HaveSomeRekage so is that not a proper form of measurement?
@@mattmarks9076 I can't tell if you're joking or not
Matt, you need help. Seriously.
Anay Pareek Just in case he isn't... Yes it is a proper unit of length measurement. You might be more familiar with light years.
According to a quick internet research the piece of aluminium is 89.9377374 cm long.
One thing I've noticed in watching many of Cody's videos: He doesn't sleep...
Sleep?.?? What's that?
Sleep is for the weak.
i thought the same o.0
@@ranSmsB Ahh that explains why I haven't heard of it.
I think it is pretty common for youtubers to film at night. It cuts down on the noise from traffic and neighbors.
"Wait, when did Cody win the Fields Medal?"
- Me misreading the title
He won for Cody’s Theorem, which allows him to measure how many nanolightseconds long a piece of aluminum is
HOW PEOPLE FIND THE LENGTHS OF OBJECTS.
USA- imperial
EVERYONE ELSE- metric
Me-count with fingers
Cody- “Its about three nano light seconds long”
ikikuraz my girlfriend said it first
Lmao
You missed out:
MIT students- Mr Smoot
The USA uses United States customary units, not the imperial system.
the usa system is based on the imperial system'
3 nano-light seconds long lmao
hi
I literally went "HA!" really loudly when he said that. LOL
Caught me off guard lol
When you dont wanna use metric or imperial
I was just wondering if it counts as metric.
As always good content that I can watch instead of sleeping
Timezones make TH-cam weird.
@@thesentientneuron6550 same. Its 11 am where I'm at
I'm going back to sleep.
Or watch instead of working! (time zones are fun, but the result is similar!)
LOL
Cody's got his own table of elements. Luminum, Neodyminium, etc. Might need some Bletch on standby too :P
Bletch is my favorite part of this channel
Neodiddlyum*
@@diogoayres7953 Neodiddlyum was not actually discovered by Cody, but a Canadian research team at the AvE workshop.
Acrost
Lmao I read the comments before starting the video. Since you pointed that out, that's all I hear now
I actually thought you'd been awarded mathematics' highest honor and were about to do chemistry to your Fields' Medal because that's just how baller you are.
Maybe the alloy is absorbing into the structure of the aluminium and when you let it solidify again the crystals expand slightly, pushing the aluminium crystals slightly apart. Would also explain why it’s slightly raised on the surface
Dexis i would go further and blame the tin or maybe bismuth (looks a bit like tin pest and bismuth expands on cooling if i remember right)
Is it possible that in cooling more water is reacting, and possibly more oxidation occurs then?
Yeah, I think the high temperatures aren't allowing water to interact, since the air around the hot plate becomes very thin with heat, there are just fewer molecules around to interact. But without the heat, the actual alloy can't interact with the "luminum" so the cycle is seemingly the best way to do it.
That's actually a plausible reason.
Dexis I was going to the comment section to comment exactly this!
This reminded me a bit of the time Cody made grey tin.
Didn't take that long thou :p
The moment I saw the grey looking substance I thought of beta tin too
Smit Lord you genuinely disgust me with how good that pun was
I may or may not have just bought some vintage tin solder molds. the battle of the pest is coming.
Cody'sLab this is going to be good, I can feel ot
"Ive got this peice of aluminum here, its about 3 nano light seconds long"
damn you cody this is why i love you
Why did you use grams and celcius we dont understand this unit
*YOU SHOULD'VE SAID NUMBER OF ATOMS MEASURED BY PLANCK'S CONSTANT AND KELVIN*
planck's constant has dimensions J.s bro, why are you acting dumb?
@@Walczyk r/whoooosh
The heat must have been keeping the local humidity too low to progress the reaction. That was pretty surprising that it reacted with water so aggressively. Seems like that could be harnessed for an emergency battery or something.
Exactly what I was thinking, the heat drove the water off and limited the reaction, when he put it in water it went off like a frog in a sock. Wonder if the water is acting like a catalyst to the reaction.
oh rob, troll fail. try again.
Yeah, this was my thought as well. Aside from humidity (in terms of percentage), heated air just has lower density of molecules entirely, which might keep the relative humidity the same, while still driving away water molecules so they can't oxidize the "luminum"
There was a breakthrough on this from the US Army Research Laboratory last year. (No details yet, unfortunately, because they're still working on the patent, but you can find articles about it online.) What Cody has done appears to be a catalyst-based reaction, which has trouble with the speed of the reaction.
hell with enough of it you could make a torch out of it (which would be super cool)
It probably soaks in laterally faster than vertically because the angle would have been extruded. The grain structure of the aluminum would probably be stretched in the direction of the extrusion.
But the grain structure isn't like wood is it? I mean it's similar in a way but would it really affect this in that way?
Absolutely love the absurd units of measure you use in your videos. Please keep it up, it's become an Easter egg I've come to look forward to.
Always a head scratcher when watching Cody, I will always love this channel
Whats this "luminum" he's talking about? ;)
+Julesernes
Instead of mediating the battle between 'aluminium' and 'aluminum', he has made a new name, 'luminum. That way no-one can complain.
+yeah nah fuck you for that picture
+Veyran
Why? It is an ineffective prank, as completely blank avatars aren't common. Now, if it was a normal-looking avatar with an insect or hair, then I'd agree with you.
+Callumunga
Now we'll just argue about 'luminum' vs 'luminium' instead
It's a colloquial thing. Cody be country folk.
Does Cody ever sleep?
Sleep is for the dead
Early to bed, early to rise. He does, just not when you do.
He seems like the kind of guy who would try a polyphasic sleeping schedule
You know what they say, "Science never sleeps".
We sleep in shifts so the aliens can't just walk in anymore. idk if it really helps, but it makes us feel safer.
You always make mind stimulating, interesting videos! Been watching since 2011, keep up the great work!!!!
Love it!!! Simply mind blowing to define a 3 foot length into 3 nano-light-seconds, have never heard anyone else do this before.
Thanks Cody, talk about out of the box thinking.
Possibly as it cools the metals are still semi-soft and trying to crystalize and the crystallization forces it move outward through the aluminum.

Next: Fields Metal on a Fields Medal!
I came to the comment section for this!
Based on my research, the Fields Medal is cast gold (no idea of the Karat value), and is cast by the Canadian Mint. Would Fields metal break down gold?
I initially read the video's title as "Fields Medal vs Aluminium" and briefly wondered how Cody had got his hands on one of those and why he'd perform destructive experiments on it :D
@@Rhangaun because it's cody
Good video Cody. Thank you for sharing.
i love your channels, the only time i get to learn new things. i applaud your science experience. i wish i knew half of the things you know.
When it heats up, it may have enough viscosity to seep through the grains/crystals of the Al, when it solidifies it expands, damaging those crystals and reacting with the aluminium and air.
OMG someone else who uses nano-light-seconds as an everyday unit!
For those wondering one nano-light-second is 29.97cm
Huse american gawd dammit
So.... Im too lazy to calculate... How many nano light seconds is 3km?
29.97cm ~ 30cm
x 10 = 300cm = 3m
x 1000 = 3000m = 3km
10 x 1000 = 10000nls (nano lightsecond)
1000nls = 1µls
10µls = 3km
@FyreSpit thank you!
thats the time light needs from my house to the nearest city.
That would be 10µs (microseconds) - time.
10µls (micro lightseconds) - distance covered by light, through a vacuum, in 10µs.
Very cool video Cody!
Thanks for breaking everything down for the layman. These videos are extremely educational
Cody, "I gotta find a spoon to melt it down in."
Me: " aaah, the good ole black tar days. "
Are you from south lebanon Ohio? If so I know your brother, well I kinda know you too. I was friends with your mom way back in the day....
@@jonross377 lol. Nope! You're the second person on YT to ask me that. I was born in Greenville. Lived in Dayton area about 4 decades. Now in Tennessee last 5 or so years.
That Josh Gibson in Lebanon seems to be a popular dude! Lot of folks seem to know him.
@@joshuagibson2520 Its a small town... everybody knows everybody there lol. I wonder who the other person was? I probably know them too lol.
@@jonross377 it's just wild to me that I lived just 30 minutes up 75 from there. He and I could have crossed paths at some point living that close. It didn't manage to happen in about 35 or so years that I lived there though.
I'd watch you make a mirror out of it.
This was super interesting, thanks for doing this!
Three nano light seconds long love the precision Cody!
"Could be used as a mirror."
Next project telescope confirmed! Would love to see Cody build one of those rotating ovens to create the parabolic shape.
I did the Hg mirror turntable thingy about 30 years ago. These alloys form gray oxide skin so fast you gotta wipe it constantly and wait for the ripples to die out. Not worth the trouble AT ALL.
So you’re saying it’s about 0.528 Smoots in length?
This was really cool. Very enjoyable.
It came as a brand name -Cerrobend- in a shop where I worked and was used to keep small metal tubing -mainly stainless- from kinking when making bends. It was kept in a hot water tank with a petcock on the bottom, and when you wanted to make a bend, you capped-off one end filled the tubing capped the other end and made your bend. When done, you cut the capped ends off, put the tubing back in the water tank and in just a minute or two, poured the Cerrobend out and voila, a perfect bend.
Perhaps all of the "oxidation" is actually reacting with moisture in the air and producing hydrogen. Maybe you should try the experiment again, but placing the sample in a dry atmosphere (sealed chamber with a desiccant) for the cooling cycles.
or do it in a vacuum
@@Andy47357 How would it react with moisture in the air then
Would hydrochloric acid help
Soo is cody ditching mercury and uses safe things????
Wth
Very interesting.
I especially liked the reaction at the end of the video.
I'm sure there are more efficient ways to harvest hydrogen, but that was a very cool demonstration.
I didn't know that. Never even crossed my mind. Cool vid, Cody.
I read the title at 4 am thinking: Wait, how did Cody get a fields medal and is he really going to destroy it !?
That music in the end sounds like it's from cyriak
Cody at 4AM
"I gotta check that bit of metal !"
This is why we watch your videos dude ;)
Breakfast + new cody's lab video 👍
"I like how it has a juicy center"
I wanna eat it.
What's up with the Cyriak light style of music? xD
Measuring in light-seconds. Love it!
Cody never sleeps!
Just needed some of that against the T-1000 then, would have slowly fallen apart over time... :P
You often mention it being 4:00 A.M. in your videos. Do you wake up before 4:00 or do you not fall asleep until after 4?
Cody never sleeps.
At 1:10. I'm just imagining Cody sitting in his truck in a sketchy parking lot with the cops tapping on his window motioning him to roll it down, as they see him sitting in his driver's seat using a Bic lighter to melt down light metals in a spoon.
Does it expand when it becomes a solid?
Could be that it expanding expands the grains and pores, allowing it to spread throughout the aluminimum more easily
Another possibility is that the difference in humidity between the hot air over the active stove, and the cooled down air
It could just be the stresses from the atoms aligning into a rigid crystal structure.
I thought it contracted when it became solid, as far as I know the only substance that expands when it freezes is water
Sadly that conspiracy theory falls short. Theres no pores in aluminium kid. Your pronably thinking about leafs or something get ur ass back to biology class kid
Yes this is a distillation of what I came up with.
First you remove the second "i" in Aluminium, and now you're removing the "A" as well? Poor 'luminum is slowly being corroded away by American dialect. XD
Hes doing that for a while now to trigger people. Same as pronouncing bleach as bletch. :D
Too bad pronouncing it aluminium is objectively wrong
Hey Cody! I don't know if you did it on purpose, but this video seems to be louder than your other videos. As someone with a hearing impairment I really appreciate it!
Watching the timelapse and seeing the oxidation 'jump' reminded me of the patterns you see in forge-welded metals, where sometimes as they cool you'll get a flash of heat that pulses through the entire piece as the crystal structure changes. I wonder if there's something like that going on here.
"Cody? What are you doing?"
"Making exotic alloys."
"It's 4 in the morning, why are you making exotic alloys?"
"Because I've lost control of my life."
I initially read the title as "Field's medal vs ..."
I love learning from you
An exceptionally entheusiastic intro :D
What about NaK ?
I've been curious if cesium would attack aluminum in any way inside an inert atmosphere or vacuum
It's not luminum, it's luminium! :DDD
Let's just start pissing off everyone equally by just calling it Lumos... :P
Nope, it's just "L".
Aaaluminimum. :D
Field's Metal eats away the second i in Aluminium, leaving behind pure Aluminum.
Num num.
I can watch alloy and odd metal videos for ever. Who needs sleep? lol Thanks for your videos Cody.
Great video!
out of laziness i once weighed some SnCl2.2H2O in a aluminium foil recepticle, bad idea, definite reaction
luminum > aluminium > aluminum
lumnum
umumum
I usually go with the original spelling "alumium", as it's guaranteed to piss off both camps.
or as my boss says: aleminimum
Get out!
This was a really good video
Your up at my time of the day!
3 nano light seconds long😂😂😂
Boom Killer So that people with the US measurements stop complaining!
US measurements as in Imperial? Because if so a nano light second is pretty much 1ft.
Tate Amstutz Imperial == US Measurements
Fun fact. 1 nano light second is roughly 30cm, or 1 ft.
More like 1/3 meter
Sleep isn’t thing anymore
What's sleep?
Sleep is canceled sorry
seen his GF recently ?
Fascinating ! Thanks Cody ! Bad stuff for an aluminium boat eh.
That's pretty neat! I wasn't expecting that reaction at the end. I was kind of hoping you would have taken the two pieces you broke and let themselves weld back together to see what happened with another cycle or two.
0:15 3 Nano light seconds long? What??
It's a real unit (29.97cm, close to a foot), and as it happens it's quite useful. I use it every now and then
What would have happened in a vacuum chamber?
Glad to see Cody finally using lightsecond distances instead of meters and such. Having respect for all the other planetary people out there
Codys Lab: always cool stuff! YEay ! :D
1:47 now I will definitely make it too
wtf dat intro music tho
DeadlyDonut17 sounds like 18 hung wet horny CowBoys ready to Rut
reminds me of Cyriak
Interesting. Thanks for the video.
Always interesting content, whether I understand what’s going on or not.
New Music!
Reminds me of Look Around You
Liquid metal is always awesome to watch
OMG! Look at his dedication! Did I heard 04:00 AM!?!? You stay awake till that!?!
I love your scientific sarcasm you just subtly add in to a lot of videos
"about 3 nano light seconds long"
When you are early and don't have anything clever to write.....😂
The s/l phase change could be taking energy from the luminum, potentially causing a local lattice change to form an allotrope more active in the air? Make a bunch of the tarnish material and x-ray to check possible alloying
A very interesting video, thank you. x
I'd postulate that the thermal expansion properties of the two metals meet at some x,y point...and the field's metal can attack the aluminium at that point most optimally. Rather than thinking of solids being dissolved into solution, consider liquids being absorbed by solids.
I can’t help but scream SCIENCE after watching one of Cody’s videos lol, they’re so entertaining
Thanks Cody for the quality family entertainment. We have a question for you. Our hummingbird feeder builds pressure every day and leaks out it's syrup. The process repeats every day. I have ideas for a gravity powered pressure regulator but it doesn't work. Can you build a better feeder?
Thanks for measuring in light-seconds, a length measurement we can all agree is best. It's a shame that time is still defined to match traditional seconds, but it will have to do for now.
I really enjoyed that one 👍👏
Cody, which liquid metal would be acceptable to use on a aluminum heatsink? Like for cooling the CPU more efficiently. Common liquid metal thermal conductors are made with gallium or some gallium alloy and would destroy it. Is there some that wouldnt?
Cody, Liquid Metal Embrittlement (LME) is the name of the process of degradation you have shown. Typically LME shows a trough of mind minimum ductility (maximum brittleness) at the melting point of the liquid metal (or perhaps a component of a liquid metal alloy?)
Thermal cycling will yield large within internal stresses with liquid metal having diffussed intergranularly and given the inherent variation in thermal expansion for different components.
.
Oh, one more thing. 'AH-lu-mi-num'.
.
Thanks for the great videos.
So, when cooled down water vapor in the air may be reacting with the naked Aluminum. I am fabricating a small MHD pump to sling Field's metal globs around a gated loop to do what der Sprengel pumpen does but faster. Needed to know if Wood's or Field's attacks like Hg. Found no references anywhere 'cept for good old Cody.
I wonder if the reaction between the two metals is specifically dependant on a certain temperature below what you are using when the hot plate is on.?
Codys so dedicated to science he no longer needs sleep he's fuled by science
Oh yessss!! Please try to make a mirror out of fields metal!
Your content is super interesting btw
My family loves your videos please keep them coming Cody! "Knowledge is power." Sir Francis Bacon.
I don't know why, but I really loved this one.
Do you think it has anything to do with the expanding and contracting of the material as the temperature changes?
Maybe it's an interaction similar to how water cracks stone in the winter.
