Glass: cut's Cody
Cody: Uses that glass in the process of making iodine to disinfect the cut
Repurposing offensive material😂😂😂😂😂
Modern problems require modern solutions
@@MrPuck45177 LOL !
Glass can not stop a God
anti-fragile
Impossible! Everyone knows that seaweed is 50% sea, 50% weed.
Spongebob Squarepants!
Just like the netherlands
I thought you were talking about my lawn. See, weed.
SomeAustrianGuy Dutch people be like “Why don’t we take the sea, and push it somewhere else?!”
@@SomeAustrianGuy pretty much 🤣🍃
Cody: so the solution should turn brown
Solution: *turns brown*
Cody: hehe
I don't know why but I laughed. :-)
Cody is a wizard
Hijacking to ask for MSG extracted from seaweed.
i was gianna comment this, thank you for providing it to the world
@@Nocturnal_Owl it’s a chemists secret 🤫
Me, cuts foot, "Ow! What a freaking pain." Cody, cuts foot, "Wow! This gives me a great idea for a science project with some seaweed!"
That is what I thought.
*fucking

Glass: *cuts*
Cody: ouch
Also Cody:*tortures glass to make a disinfectant to treat the cut*
And then stores said disinfectant inside it's glass brethren to add further insult to injury!

You nutters
Alright, but can you extract seaweed from elemental iodine
Dagan Ward I laughed
Only on a full moon

@@PaulMab9 you should feel ashamed
TEcnically it's seaweed extract. :P
USA: miles, yards, feet, inches
Rest of the world: Millimetre, centimetre, decimetre, metre, kilometre
Cody: nano light second, smoot, chain, furlong
Dont forget about chains and furlongs
U forgot the lumina.
yes thats right ... USA and Myanmar uses these units
Trains added, thank you
I have never heard someone use decimetre.
1:08 If you wish to extract iodine from seaweed from scratch, you must first invent the universe.
Ugh that's always the first step! I'm so tired of doing it every time I wanna get something done! ;)
I read this as a bug report, so I'll mark it could not reproduce.
Mybuttox R. Smooth sounds easy
Whoop, Ohhhh Ohhhh.
I’ll just fish a Universe out of the trash
For those confused about the units Cody used, 600,000 Smoots is about 50703.889 chains, or 5070.3788 furlongs.
Garrett D thanks man I was just a little confused and now I understand what he was saying
Smoots I think is 600,000 meters or 600 km
I see, thank you for clearing this up for me. About how far is it in light-nanoseconds?
And that'll be about 50,700 cricket wickets...
A Smoot is about 1.7m, named after the guy who measured a bridge using himself as an MIT prank.
EDIT: Matt Parker has a good video on it.
This is probably the fanciest looking thumbnail on a Cody’s Lab video ever.
VPG Darkstar he was excited
He shows his creative side when on seaweed
Because he asked on Facebook if somebody wants to make the thumbnail more interesting and they did :P
Probably playing around with Gimp...
In fact i didn't even recognise it as a Cody's Lab video just by looking at the thumbnail.
Is this guy wearing chain armor
I have subbed to your channel for a long time!
Yeah he is lol, he made it himself and wears it as passive exercise :D
Yeah he’s got access to creative mode
@@BambooBailey uhm
yes
Cody: *cuts foot*
Cody: *goes to store, buys seaweed, extracts iodine, makes tincture, uses tincture to disinfect wound*
I mean yeah why not
Thanks Cody for telling us that you live 600,000 smoots from the nearest ocean thanks for that useful frame of reference
lubricatedjellybeans I was actually pleasantly surprised to hear him say it. It’s the first time I have since Matt Parker’s video
FYI, 600.000 smoots is about 1020 km, or 630 miles. And dont be salty. It's undoubtedly the only acceptable non-SI unit.
@@rfldss89 pirate ninjas?
@@nikkirennardo5100 I was pleasantly surprised as well :P I forgot where I heard it first though, I guess it easily couldve been Parker's video
@@rfldss89 Actually 600,000 smoots is about 634.5 miles and 1021.1 km.
now extract the salt from seaweed and then make iodized salt
his first extraction/filtration was iodised salt
@@chrisweatherley9587 Maybe with a little carbon too that might be healthy also? I was wondering what the black coloring is from.

I've been binging hours of Cody's older videos, like the older refining videos, and I've learned 2 things. One: I've been watching your videos for a lot longer than I've thought, and Two: I've remembered why I love your videos so much. Your content has made me a smarter person over the years, and has helped me realize my love of science. I've always loved science, and your videos have been an outlet for that. I'm still young, I've got my whole life ahead of me and can still make choices about what I'm going to do with it, and these videos have helped me figure out what career in science that I'd like to go into. Please, never change Cody. Keep making videos. I'm just one of the many people whose lives have been changed by your content, and I'm sure many people have similar stories to mine.
Now convert it back to seaweed and I will be really impressed
that would be IRONic
Well
It isint episode about iron bruh
Just make sudum idodied solution and grow seaweed in it.
Cody’s Lab in 25 years: Is there less Iodine from the seaweed on my mars colony than on Earth?
Pretty optimistic, but i am on board!
Count me in
Yeah me too
Spaceweed
He should definitely be top pick for Space X's mars mission.
Cody:
*cuts foot*
*realizes he should use some tincture*
Cody: lemme go buy some seaweed
Exactly.
Named after: Oliver R. Smoot
Imperial/US units: 5 ft 7 in
SI units: 1.702 m
or 634ish miles
1 smoot = 5.5 feet.
god damn it cody, why do you make me keep googling your archaic units of measurement.
Well and you just converted one archaic unit into another archaic unit.
@@FruitingPlanet While i do agree with your statment, feet is a relevant unit of measurement in my country, so its not archaic to me.
@@o0kaelas STUPID
EVERYONE USES METRIC EXEPT AMERICA AND A SMALL ISLANF
barnyard yeah by using the metric system
Goliath was 2 smoots
We tried to do the same thing in chemistry class, but for us it didnt work anywhere near as good as for you. Still not sure if we did something wrong or just had the wrong kind of seaweed :/
To be fair this is like my 5th or 6th attempt at it.
Easy to do you mix up a step/like go to hot and it goes up in smoke. There is a fine balance.
Check out Cody's 2nd channel CodysBlab to see the less impressive results using a different type of seaweed (Nori). The amount of iodine by species is pretty different. Also he uses 2 kg? in this video, thats a fairly large amount of seaweed i think.
Is it just me that gets real excited when cody uploads?
you should learn chemistry you look at the world differently. EVERY THING can become EVERY THING ELSE with the right knowledge.
@@rdkonevrd9898 yes! I'm fascinated with what I've learned in chem class this year!
@@spegatti3108 oh your in school still not thet. chemist with a degree that's where the fun begins if you work on researches and stuff.
Cody is great.
No it's just you. We all are here by accident.
I don’t have a witty comment about the piece of glass and using the iodine on the cut, but small things like that are part of the character of this channel that I love so much.
If irl was a game Cody has one of the best choices of classes in the game.

"Forms in the heart of a dying star" so....Mjolnir = iodine. Got it.
technically everything but hydrogen is from an old star .....
@@alfoncejean8826 not true, there were some light elements such as He and Be that were formed during the big bang
@@kelvinluk9121 if you say soo.
Astrophysics us not my specialty
@@alfoncejean8826 Astrophysicist here. Kelvin Luk is basically right: Hydrogen, most of the Helium, and some Lithium was formed in the Big Bang. (Beryllium though is mostly formed from fission caused by cosmic rays). Most of everything else comes from dying stars -- either supernovae of massive stars, white dwarfs, or the outer layers of low mass stars. Also interesting is that the heavier elements (especially above atomic number 44) mostly come from merging neutron stars, which is a pretty rare event!
Some notable examples: Almost all oxygen atoms were synthesized in massive stars and released in the supernovae. You might think that iron would also come from exploding massive stars, but since it's in the core, not a lot of it is actually released by the explosion -- instead most of it comes from exploding white dwarfs. For mercury, most comes from low mass stars. Almost all gold and iodine came from merging neutron stars, which if I remember Avengers: Infinity War correctly, is also true for Mjolnir and Storm Breaker. :P
Talking about theory as fact. Mmm
8:59 I thought that bottle said "brain alcohol" for just a second, and my first thought was, "Is that ethical? Is it even legal?"
Probably not ethical, but definitely ethanol.
50% ethical alcohol ! Don't ask about the rest... lol
But is it possible? Is there enough sugar in a brain to ferment? It's mostly water+fat+protein right?
Been following since you had < 30k subs and will continue doing so until the end. I love your videos so much and best of all, you arent one of those people that begs for subscribes and likes. Everyone who asks for it are basically insulting you, like you wouldnt figure out to sub if you like the content? You just do what the title says and no bs. That's what I truly love about you Cody. Keep up the great work.
All your videos are amazing Cody. I love your insight.
Up next: rocket fuel from all purpose flower
Well, you can extract starch from flour and nitrate it with the usual mix of acids the same way you do with cellulose. You can probably guess how that behaves
He did extract jetfuel already from Gumweed though :D
I didn't know there were all purpose flowers! Should be a great addition to my bouquet!
I think Cody has a video where he extracts flammable oil from a flower so hey, maybe one day
@Hernando Malinche There are many types of rocket fuel. The simplest combination is oxygen + hydrogen, but many high-energy chemicals have been tested and used as such.
Loved the use of Smoots, it should be used more often, to define arbitrary distances. :D
0:29 600,000 smoots is about 634.4697 miles(1021.08 km).
I could listen to Cody all day about how elements were created
Hi, my name is Ian McCollum, and welcome back to another episode of forgotten wea- oh wait, wrong channel- Hi everyone welcome back to Cody's Lab!
See if you can find any radioactive elements in Japanese kelp. :-) BTW, great video!
+electronicsNmore:
In U235 fission reactors, Iodine 131 forms among many other nuclides when U235 fissions.
In order to extract the I 131, they heat uranium oxide fuel elements in a container. The elemental iodine vaporizes and solidifies on the container calls.
One of the big problems for reactors is when there is a leak. Iodine easily escapes since it vaporizes easily, even at room temperature. They give the population potassium iodide pills (KI).
The idea is that our body uses the non radioactive I 127 for making the 2 hormones in the goiter instead of I 131.
I 131 is used as a radioactive tracer to detect goiter problems.
The half-life is 8 days.
It might be difficult to detect the I 131 by now.
@@louistournas120 I was thinking of Cesium.
Really love your channel man, you have the most interesting videos. Such a wide range of stuff, and all pretty unique compared to what you normally see on youtube. I'm glad a channel like this is successful.
I always enjoy watching you in the things you do.
Your videos are inspiring me to wnat to do what you do. Science is my favorite class in school!
Very nice!
A few hours ago I posted a new video about iodine (V) oxide: I2O5
Same
So stoked to see comments like this ! Go check out nile red too he's another guy that might inspire you guys too .. ane if Cody sees this *tips hat ,good work as usual dude !
If you are interested, I'm also making chemistry Videos. I'm mostly doing exotic Thermite reactions and high temperature chemistry.
Do you just casually wear your chainmail around? Is that for gains?
He uses the extra weight to loose weight... And he can't get stabbed.
mpk 666 he can still get stabbed. It would just take a far more determined stabber
@@PaulMab9 *Julius Caesar has left the server*
He has video's in wich he makes the chainmail and explains he'll wear it quite often as a form of passive exercise.
@@niekpauwels9569 my brother made a shirt in his sophmore year of high school(2003ish), he had a bag of rings and would just add a row and spin the shirt on his torso, he even cut the rings during class too. He was a straight A student so the teachers never complained for some reason, but then I remember we had rifles and shotguns in our trucks' gun racks in the parking lot so I guess it was a different time.
I love the synthesis and extraction videos. Right proper chemistry!
I really wish there was more content like this on CZcams, I'm sure I'm not the only one who misses this stuff, you are awesome Cody
Hey Cody! Now that broken glass is sterile so you can cut your foot again with less risk of infection! Ride ride ride!
Oliver Smoot was 5' 7" so how many Cody's is it to the Ocean....
Approximately 327 chains, or 32.7 furlongs

Yes, I love these kind of videos! Keep ‘em coming!
I'm glad to see you making more videos again.
I agree. I loved the mine videos and now they're all private. People need to toughen up and stop ruining everything for the rest of us. I'm sure whoever it was only looked at the title or was mad their comment got no likes.
Cody, you forgot to mention the best use for iodine.... Touch powder! That stuff is so fun.
I love your use of obscure units of measurement.
Love every second watching your genius.
Cody ends up bleeding or having a scrape in a lot of his videos lol

This video was sneakily very informative. it's incredible! Thank you Cody :)
Like the conversions. Nice lab
Iodine is also used to help with radiation sickness I believe.
It actually only floods your thyroid with non-highlyradioactive iodine so that it doesn't absorb the nasty radioactive variety.
^^
tl:dr iodine slows the absorption of radioactivity
Next video~
Iron bar extracted from human blood
That might be 3 or 4 videos out.
"We start with some blood I got in a cloth from when I cut my foot on a piece of glass."
Or probably gold if he is willing to go the extra mile
I love this channel man i love science and i love how vanilla your channel is yunno. Like youre not really flashy or anything you dont have these big intros or anything that makes you anything youre not. in my eyes its like you care about your content and channel because you care about it not because we want it and we want you to care about it. It's you making your video in a one sided manner and people love it. AND FOR That you are a Gem my friend.
Barely half a minute in and I'm already loving it.
"roughly 600,000 smoots."
God, I admire Cody's vast knowledge of Chemistry
Did you really just use “smoots” to describe how far you are from the ocean? 😂😂😂
NERD!!
Nathan 110%
A smoot is 5.5 feet
There's something strangely therapeutic about watching you extract elements from random things. Please post more... I do love these videos!
Old school cody "watch me cut up my hand and insert this magnet!"
New Cody "if this cut is bad look away."
Look what youtube did to our boy.
I was actually just about to attempt this myself using seaweed straight from the beach. I was thinking about using either chlorine or electrolysis to oxidise the iodine from solution, hopefully I'll have a go at this soon.
Finally an updated version
Hey Cody! I'm a freshman biochemistry major in college and in class we discussed acid equilibrium with relation to solubility and precipitation, and I instantly thought of your precious metal recovery series when you used strong acids to make precious metal solutions and purify the gold or silver! Thanks for making great content!
I live in Boston and I appreciate your use of the smoot measurement system.
8:30 *literally me everytime I run out of weed*
Haha right
Haha wrong
Woah, you know Cody is serious when he uses a custom thumbnail
Wauw great! Finally this is the best nostalgic and usefull chemical science from cody! Thats for why i subscribed ten or so years ago!
The glass that cut your foot helped you make iodine to put on the cut. Poetic justice right there.
"600,000 smoots" xd
Genius at it once again.. we all love u playa! 👊1💙1👊
Hey Cody, I must say your videos have been keeping me entertained and interested over the last couple of weeks as I'm sort of binging through and I want to express my gratitude and respect. Much love. I also want to use this opportunity to share something you probably already know, but I haven't seen so far in any of your videos, which is Gallium attacking Aluminum alloys. Usually Gallium won't react with Aluminum because of the protective coating of aluminum-oxide, but if you scratch that up and coat it with some liquid Gallium, a couple of drops can slowly eat away entire bars and turn them into something so brittle you can break it with your bare hands. Fun to watch the Gallium work under the surface of the aluminum oxide layer and eat the metal from the inside out. What's also interesting about this is that the resulting aluminum-gallium alloy reacts fairly heavily with water, producing hydrogen gas and aluminum oxide and leaves the gallium to be fully recoverable. I would absolutely love to see you work out a video with that explaining these processes, or perhaps exploring the possibilities of using this reaction as a fuel or energy source. Again much love for your work, you are amazing!
Awesome use of the smoot unit of measurement.
Now, I have done some research. I thought Smoot was just slang for how far away something is, but Smoot is an actual unit of length. So there you go! :D
10:03 im seeing "yeet" written on the top of the tincture label...
I always appreciate the usage of obscure units of measure.
Awesome love the process.
Cody, incredible, you're just a modern day McGyver,and a pretty good one I might ad. How did you learn all this soup full of knowledge???!!!

well cody
Well put it this way: This video was filmed, edited, parts re-shot, re-edited, posted to patron, re-edited, parts re-shot, added text, more edits to make everything line up properly, rendered, uploaded, and published all while I didn't sleep once throughout. I think you can see at least 3 day/night cycles go by. and looking at the timestamps on the files on my computer it looks like I didn't go more than a couple hours between filming or saving something.
@@theCodyReeder I appreciate the dedication, but that's unnecessary stress for you. Everyone can wait a day or two more for a video. If this is more of a rule rather than exception, please rest more, your body will thank you 10 or 20 years from now. I'm fairly certain everyone around you would appreciate a well-slept-Cody as well.

I was wondering, could you and would you extract cyanide from apple pips? Or, since they are bigger, cherry seeds?
The way you described where Iodine comes from makes me want to go and buy iodine from pharmacy and hold it in awe as if it came from the moon. And then keep it on my desk at work, as any Star Trek fan would keep enterprise model on their desk.
Been a while since I seen your chemistry videos, pretty fun!
Weird question of which anyone is allowed to answer, but a potential good to know subject. Iodine is used to reduce radiation absorbtion into the thyroid gland, but is it a certain quality, type or quality of iodine?... Or can you literately consume seaweed to get sufficient amounts?
There is *weed* in the *sea* ??? I need to go to the sea more often.
it's really dank!

In my country, we add iodine to all the salt available in stores.
What an ingenious innovation!
Just like alot of countries worldwide. They don't call it iodized table salt for nothing!
Thanks for putting the reaction on screen, that's much easier to follow!
Watching this was certainly more fun than working on my two papers. And well, I've always wondered how much iodine is in seaweed, so that was a superb reason not to be researching on Husserl, Heidegger or Merleau-Ponty... Thanks for the upload, Cody! Hope you're doing well! Xx
