Mercury vs Alcohol Thermometers

[@EduRenesto]

Cody's relationship with Mercury is more beautiful than 98% of all love stories in the world

[@brinkyb6663]

Edu Renesto even better than twilight!

[@fsen1999]

the other 2% is the relationship between Cody and vacuum chamber's

[@ThreeLetters3]

Edu Renesto the top 1% is gravity falls fanfic

[@JoeyBartlett]

Except for his relationship with Canyon.

[@yaksher]

That's so true. I'm going to write a Cody x Mercury Thermometer fanfic.

[@DrywallJackson]

Fun story: earlier this year, I brought in gallium to my school because I'd mentioned that I own some to my 11th grade chemistry teacher. Gallium actually takes a long time to warm up so all I actually ended up getting was a small handful of it melted. Still, I walked into the office my biology teacher from last year, the handful of liquid gallium outstretched to him, and said "Mr. Dahl, is mercury dangerous?" He freaked the fuck out.

[@vx-iidu]

[@Alex_Off-Beat]

lmao awesome. I almost wish I was still in school so I could try doing this

[@LazerLord10]

We had mercury thermometers in use for a high temp experiment in my high-school (300C). Someone left the heater on at max temperature for a while. It burst and it was quite the fiasco. I don't think anyone was in the room when it happened, but yeah.

[@theCodyReeder]

Probably didn't have enough room to expand, they used to make mercury thermometers for that high of temp but if you used a 100C one in a 300C oven then yeah it'd break.

[@LazerLord10]

Oh, I meant that the experiment was supposed to RUN at 300C. I think the termometers were good to 400, but obviously the heating element went a bit past that.

[@thexp2808]

You're a great creator. Please keep up the good work. I really appreciate everything you do for KZbin. You've been providing me with entertainment for many years. Thank you.

[@x9x9x9x9x9]

After seeing you got these the other day I started looking them up. What a lucky score.

[@Joe.Rogan.]

Heh.. i always wondered why nurses would flick and shake the thermometer in older movies. Another new random fact learned to push out something old i learned in University.. awesome.

[@marianoaldogaston]

those mercury clinical thermometer are really common here in Argentina.

[@katawatenshu]

woah

[@YCbCr]

Just as the description of it as a clinical maximum thermometer dawned on me... just a classic old armpit thermometer. :) Used to be the only choice here before the '90s, now phased out completely. Still got one though, electronic ones can only get worse, draining batteries and so on. :)

[@lazar2175]

CaptainTruth It basically "resets" it. It pulls mercury into bowl,starting the measuring from 0.

[@schwarzarne]

SilenT●CSGO & More! Yeah no shit captain obvious. Watch the video.

[@ER-ns3pg]

You are my favourite KZbin Channel!! I have never written that, but thank you for all this great videos!! You're great!

[@micahphilson]

In elementary school, just, say, 10-ish years ago, one of my teachers found an old, broken mercury thermometer. We didn't have to evacuate, and in fact, he cleaned it up, put it in a small tub, and brought it around to all of us and showed us how cool mercury is and how you can play with it (safely, of course, and also saying we definitely shouldn't do it for safety reasons)

[@ChimaeraTom]

this video reminded me of one of my old history classes. in a hypothetical lesson 5 people were given various medieval "remedies" to try to "sell" to the rest of the class' "ailments". .At the time none of us knew the origins of our cure, but i managed to use the known 'facts' at the current time to successfully "sell a cure" to 28 out of 30 people. it was afterwards the teacher told me i was recommending Mercury as a cure and in a large enough dose would have KILLED most of the people i was treating. as an avid history/science fan 15 years later still impresses me. a bit off topic but i love your vids cody and this reminded me of that

[@zacharywarnimont6007]

loving the high volume of videos you're putting out, keep up the great work!

[@wacka.]

Cody: "thats why Fahrenheit is sticking around" Rest of the world outside the US: "Whats Fahrenheit?"

[@symbioticcoherence8435]

*What's

[@wacka.]

The rest of the world is bad at grammar I guess :P

[@brianluna7836]

wacka "That's why Fahrenheit is still sticking around to this day." Implying that that's why they're still around, not to be confused with your misinterpretation

[@louistournas120]

+wacka: That doesn't make sense. Fahrenheit is still used in the USA bc they lag behind or are lazy. Some of the reasons is because of industrial equipment that is set to produce a certain can, such as cola cans (355 mL), milk carton (946 mL), acetone cans (946 mL), paint cans 3.78 L). That's what they print here in Canada but the equipement is for USA england system. Of course, there are plenty of cases where you can buy 500 mL of peanut butter, 1 L of orange juice, 2 L of cola. They don't want to spend money to change the molds.

[@0_IQ_Noob]

We do that too , in Bangladesh

I feel like you and Ave are having a low key, passive back and forth debate about Mercury's danger

[@theCodyReeder]

we kinda are actually.

AvE and codys lab the 2 best channels on the KZbin

[@souravzzz]

This video brought back a lot of memories for me. When I was a kid I loved to play with couple of mercury and alcohol thermometers. I broke one, spilled all the beautiful mercury on the floor, and was just fascinated by their appearance. Glad I did not eat the shiny droplets :)

[@adrienperie6119]

I love that you respond to your viewer's curiosity quickly, I immediately wanted to know why you preferred mercury thermometers when you mentionned it in the last video, even though what I expected was pretty much true this was interesting and I even got to feel like the channel is based on my thoughts for a few minutes !

[@Ktulu789]

Dude, this vid just told me why do thermomethers need to be shaken. I always thought that the little pinch inside the tube was an error in the manufacturing process. Now I learnt something! And that's not the only thing I take from this vid! Thanks!

[@christianhildalgo]

Lol, you are so right about chemophobia. A couple months ago a guy on my school suddenly had a panic attack on chemistry class. The teacher was showing the process of electrolysis and that guy totally freaked out thinking that those bubbles were some kind of toxic gas....

[@SeanHodgins]

Years ago, when I was in high school, this girl stuck her thermometer into a lit Bunsen burner. She happened to do it while I was walking by and at that exact moment the end of it exploded all over me. Luckily it was only an alcohol thermometer, and it covered me in red dye, and glass. It looked like I was bleeding from the glass, but somehow no cuts.

[@AbudBakri]

Once broke the mercury thermometer in my chemistry lab. Let's just say my teacher wanted to send me to Mercury. Or to the Sun.

[@planetrob555]

I remember my temp being taken by nurses back in the late 60's and 70's and they would shake it down like that! Memories!

[@jannepeltonen2036]

We had a mercury thermometer to measure fever when I was a child. Or actually we had several. The small droplets of mercury running on the floor quite clearly explained the name quicksilver (or 'elohopea' in my mother tongue, which would be more like 'live silver'.) And yeah, having to shake the thermometer before using it sounds very familiar :)

[@lfcqr123]

I just love how Cody is talking about how he is sad that the thing he is holding is illegal to hold

[@wyldeman0O7]

it is very satisfying when you use the uncertain significant figure over rounding in your measurements.

[@maximc3876]

the next week part is really cool it give you a little hint and something to think about over the week

[@arcturussirius7139]

Cody has shown me the true value of mercury

[@tunafishjoe]

So that's why you see doctors in old movies waving thermometers around! Nice! I thought it was to dissipate heat or something. Thank you!

[@symbioticcoherence8435]

great observation, I never noticed! :)

[@lajoswinkler]

Um, how old are you? o_O

[@clumsymind]

We actually used mercury thermometer in our family for very long time. One that you have to shake in order to reset temperature. It was in Celsius since we're from Europe ofc. But now that old one got broke coz it fell down I only got to see electronic ones in stores. And you know what...you may think oh that's cool..but actually they need battery and also are stupidly inaccurate. Idk why they don't have more precise ones for reasonable family price anymore. It's like...yeah everyone is too stupid nowadays we have to babysit everyone or something. It's silly.

[@Jman1698]

Any updates on the anaerobic digester?

[@andrewkovnat]

I would also like to see an update on that!

[@theCodyReeder]

I killed it shortly after my last video by inadvertently pulling the cord out from the wall and not realizing for several days after which it had cooled to freezing. I'll start it back up once it gets a little warmer.

[@Deucetrinal]

I was really sad when I heard that NIST would no longer calibrate mercury thermometers. I'm glad you picked some up, I'm going searching for my own supply of old thermometers now.

[@PartVIII]

I noticed a major difference in temperatures whenever i used alcohol thermometer instead of a mercury thermometer for distillations, but i never really looked too much into it - i just stuck to mercury thermometers to be consistent. Thank you for the video!

[@emilyp2580]

Nostalgia moment for me, my parents took my temp with a mercury recording thermometer when i was a kid. I used to play with it all the time. It broke from a loose grip while shaking the mercury down lol

[@sneffels]

That's all we had when I was growing up, the mercury thermometer. I never even knew they made that kind of thermometers using other kinds of liquids

[@tigertriumph1453]

I was actually watching your "Spinning Mercury with Magnet and Electricity" video, when the notification came in for this vid. Coincident?

[@robplotts9412]

[@spamy6661]

I never realised that thermometers where so interesting, thanks!

[@robertomartin8731]

Now I know why we wave the thermometer very hard when we were young before taking measurements :D

[@symbioticcoherence8435]

Once when I was the the "german museum" (a museum in Munich for science and technologie) and for their demonstration of absorbtion of IR-radiation on different yet same-looking surfaces they used mercury thermometers. The heater was overpowered and the thermometers were close to bursting, I told the staff and they took me to the back, to regulate the electric control unit. Had a nice conversation with them afterwards :) you should visit this museum if you ever get the chance to, it is awesome, I went there maybe 8 times, and I still haven't seen everything

[@dapperdan6382]

I love your videos cody. you seriously remind me of watching mr. wizard when i was a kid.

[@16m49x3]

Hey Cody. Appreciate the Celsius mentions.

[@xeigen2]

I have a mercury maze toy from 1978, very cool little thing. Shame they don't make those anymore! You really couldn't replicate the way it behaves with anything else.

[@MrBiky]

I remember when I was a kid in mid grade school, I was using a lighter to rise the temperature of a thermometer. I never knew what that "blue liquid thing" was and everybody including my school teachers also assumed it was mercury (because that's how educated we are here, but that's fair, considering 90% of the people back then probably never saw how mercury looks like). As I was heating the thermometer, in just 5 seconds or so, the top of the glass exploded and spew hot blue alcohol on a wall (and glass shards). Even though everybody thought it was mercury, we just opened a window and cleaned that alcohol with our blackboard sponge and resumed activity.

[@ONLYUSEmePENUS]

in the aviation industry if a tiny drop of mercury is dropped on an aircraft, the hanger is locked down and all personel on the aircraft are instructed not to move, it is then xrayed until found, this is due to the amalgamation process with which can take about 3-4 minutes even through surface finishes and due to mercurys viscosity, slight deviations in the aircrafts pitch and roll, could send the mercury anywhere in the aircraft, the amalgamation basically results in a serious loss of structural integrity in the area

[@Harshad_01]

Wow. Learnt something new today. I have been admitted in hospital a couple of times and always wondered why the nurses and doctors flicked the thermometer like crazy. I didn't bother asking as I thought it must be something they just do. Looks like they were trying to reset the temperature reading.

[@ares395]

We had clinical thermometer like that in my family as far as I can remember and it works far better than the other ones that we have

[@Flyingwigs]

when i was a kid, i found some mercury in the sink when doing dishes. my mom called the poison control center and they basically told her it was nowhere near enough to be harmful, and even if it were swallowed, it's not likely enough to do much harm (it was from a very small thermometer)

[@DrakkarCalethiel]

Just opened KZbin, codyslab uploaded a new video (11 seconds ago) Well that was just the right timing. Very interesting video, now I know why some of my thermometers are all over the shop.

[@mrMacMilli2000]

Drakkar Calethiel i really can not figure out what you are trying to say

[@DrakkarCalethiel]

Ace Mcloud I just opened the youtube app and the first video on the "homescreen" was this one which got uploaded 11 seconds ago.

[@mrMacMilli2000]

Drakkar Calethiel i ment about your thermometers being soread around the shop

[@DrakkarCalethiel]

Ace Mcloud I meant the measurement. The mercury based one shows bang on 90 degrees and the three non mercury based ones are showing measurements which are way under the 90 degrees, they were accurate before, but now they don't show the right temperature which ruined some distillations in the past.

[@pottieleon]

Here in Brazil, these flicking mercury thermometers are standard for taking temperatures at home and hospitals and they cost like, 0,50 USD each

[@geebsterswats]

I remember when I was in 3rd grade (prob around 1986). whenever someone felt sick, they would go see the school nurse. she would stick a glass/mercury thermometer in your mouth. not before she flicked it with her wrist however. when she left the room, if you were dumb enough (or smart enough;) to take the thermometer and put it on the radiator, you may have went home early from school. I however, would take the thermometer and rub it along my pants fairly quickly. the friction worked nicely to indicate that I had a fever. however, there was one time I rubbed it too hard, and the nurse thought that I had a fever of 103.9F! suffice to say that after a trip to the hospital, I never got away with it again!

[@jteegarden9197]

i worked at a public high school that had projectors and the bulbs often went bad but occasionally the bulbs would explode and the principal would clear the hallway for the entire day and have it cleaned it was the funniest thing when the parents would come in and try to convince the school that their kid had mercury poisoning

[@robertkubrick3738]

In school at APG Maryland, it was break the Tritium night sight on the 60mm mortar.

[@waxore1142]

now I know why my grandmother use to shake the thermometer down before she used it.

[@andregross7420]

Loving the frequent uploads!

[@Felixkeeg]

We still use mercury thermometers in our organic chemistry lab. We basically only have some Mercurisorb around, in case something might happen (somebody dropped it into an oil bath recently lol, it wasn't turned on though)

[@johndifrancisco3642]

I just want to say that if you do not go to Mars, Earth will be a better place because we need people like you to teach.

[@matsv201]

Remember when my primary teacher in first grade should show how a thermometer worked with a drink straw and a camera film container (that one that is used for old chemical-film cameras that nobody use any more) She had tried with thick straws, but she could find any, so she took thin once... Anyway put some scrubing alcohol and food coloring. First putt it in ice. Having to refill it several times. Then she putt it in boiling water....... and spray painted the ceiling.

[@manjunathvishnumoorthy7479]

Here in India we still use mercury thermometers for all our lab experiments. Never knew it was banned by law in US schools. Good to know! Cool videos cody. Keep up the good job!

[@ForOurGood]

Maybe you could cover the Minamata incident a little bit and Minamata disease a little bit. I get it that people are probably oversensitive, but these types of incidents are the background for this I believe.

[@lajoswinkler]

Minamata has nothing to do with thermometers. It happened because mercury sulphate wasn't removed well enough from the waste water leftover after acetaldehyde production before dumping it into sea. It's impossible to even compare it. This is about mercury, and Minamata was about mercury sulphate.

[@ForOurGood]

you are correct.. I am sure most people would get that. I am just saying Cody should cover why there is a fear of Mercury, discuss each end of the extremes so people can be better informed.

[@JoshuaNicoll]

My old science teacher used to put me (I have no idea why, I was probably the most dangerous one of the bunch) and the smart kids into a group together and gave us all the nice equipment, Mercury thermometers, much more concentrated HCl acid (I don't think he even diluted from the 70% it was in the bottle) and only barely checked up on us, as he was trying to drag the number kids along and make sure the middle of the road ones where doing Ok, but he must have been right because we never had an issue. I don't see why people are all so scared of chemicals, it might be a pain to clean up but once it's done right it's fine.

[@videomaniac3607]

I was talking to my science teacher about mercury thermometers and she was telling me only certain sixth formers are allowed to use them and I asked how many thermometers generaly get smashed and I was told she was surprised non had been smashed as I heard glass smash behind me and my teacher say that's why we don't let people use our mercury thermometers

[@GMCLabs]

happened at my school back in the 90s. Science teachers thought it was bs. At least I was fortunate enough to have had a sealed dish of mercury passed around in one of my classes before the Hg paranoia began. In science academy I actually got to use a Hg thermometer, the teacher just told me not to let the rest of the school know where he hid the Hg thermometers.

[@woodyofp8574]

I used to play with mercury when I was little. My dad had a big jar of it I used to play with. I'd roll it around on the couch, but it'd never soak in, and could stay together well. It was fun. I'll probably allow my kid to do the same. I mean, it didn't harm me any.

[@nirzgames4251]

the bend in the thermometer is called constriction in case you were wondering

[@KevinEthridge]

Back when I was in Jr. High School (early 90's) I did drop a mercury thermometer during science class. The teacher just cleaned it up after class.

[@WaltonPete]

I can remember when I was a kid, whenever I had my temperature taken the mercury thermometer would be placed under my tongue, for a minute or so and then read, then the doctor / nurse / my Mum would vigorously shake it to force the mercury back into the bulb using centrifugal force. We were wild back then! Once, my brother bit down on the thermometer and broke it in his mouth and my Mum was much more concerned about the broken glass in his mouth and the "expensive" thermometer than any risk from the mercury!

[@hoshiataru]

Oh wow! I remember that flicking mercury thermometer too! We used to use those whenever we get a fever too. When I was a kid my mom taught me how to read it and I was so proud of myself. One time I accidentally flicked it on a wooden arm chair and it broke into little silver balls I thought it was like magic! It's so sad they're now phased out in our pharmacies.

[@travisbell1732]

Why I love Cody. Has the Utah accent. Merery. I'm from Layton, aka Layon. Love you're vids Cody!

[@ilostmypie]

I had a chem teach when i was 11 that was furious at my breaking of a mercury thermometer. she said "thank you for giving me cancer when im 60" didnt use the sulphur bottle for mercury spills, just had a go at a kid for an honest mistake. (they should teach you to put anything that rolls in the spine of a book really early on, top tip there)

[@HenkJanBakker]

Broke a few of those mercury medical thermometers in my time. Filtered out the glass and had some cool mercury to play with. Yes I held it in my hands and did all kinds of experiments with it. Still here. And not sure if I was lucky or if my many medical problems could be caused by me inhaling or absorbing mercury. ..... Will ask my physician when I see him...if I don't forget that is.

[@Golem386]

My school in germany got evacuated once when some people accidentally dropped a mercury thermometer (alledgedly a large one) on the ground in the schoolyard. After that, although they recovered most of the mercury, half the school was off-limits for ~2 weeks (until the holidays) and you weren't allowed to go anywhere near the schoolyard for ~14 months.

[@R2Bl3nd]

I can understand the panic if it were filled with, say, dimethylmercury, a very potent neurotoxin, but mercury itself really isn't as dangerous as people think. Better safe and sorry, sure, but sometimes I think being that safe is a waste of time and resources.

[@Golem386]

I agree. There are a few chemicals I'm trying to get as far away as possible from - including Organo-Mercury compounds but certainly not Mercury itself. I wonder how much they paid for the specialized cleanup company back then - considering it was outside, it's even less worrysome than the usual "broke a thermometer" incident. But I assume it's all about liability. Nobody wants to take any chances whatsoever or risk some public scandal...

[@R2Bl3nd]

True about the liability thing. I don't know how litigious people are in Germany, but I know that if it were in the US, they would do that just to cover their asses in case there's that one parent who overreacts and threatens legal action.

[@harperhopkins8931]

I'm loving this run of short, low-production-time videos. Is Cody clearing out an archive of cool old footage or what? Keep it up!

[@kotofu]

We had a clinical mercury thermometer when I was little (only thermometer that we would use). Never really thought about the inner workings :O

[@Azivegu]

I once got out of a test because of a fluoride leak xD I studied geology and had a test, but in the lab close to where I was taking the test, one of the tanks holding the hydrogen fluoride started leaking. All hell broke lose as everybody had to leave the building (we were instructed to keep 100 meters distance from the building) but being geologists, it wasn't long before someone got a few crates of beer from our student organization and we just had a nice relaxing break out in the sun while we watched the emergency contamination crew fix the problem xD

[@MrTurboturbine]

How would a mercury thermometer compare to a more modern platinum resistance thermometer?

[@VintageLynx]

From my work in a lab, there is good and bad points for both. A good mercury thermometer can be as accurate and much more stable over time but you really need a meniscus reader to get that accuracy so it's harder to use in a busy lab setting than platinum type. Plus platinum type reduces variances of how different people interpret the mercury column between graduations.

[@MrTurboturbine]

@@VintageLynx Interesting...

[@anatoleh1]

Hey you should make your own mercury thermometers! That would be awesome :)

[@methamphetamine9363]

Loving the new schedule Cody, but don't overwork yourself!

[@Andre_Berthiaume]

Hi Cody. At 5:56, you say that mercury thermometer calibrated in F are easier to mass produce than Celsius ones based on the expansion of volume. I don't follow your argument: how if F better than C here? It's still just a linear relationship between volume and temp... so what am I missing?

[@mysteryman7877]

Andre Berthiaume it's just a nicer conversion rate. It's easier to convert volume to Fahrenheit than volume to Celsius.

[@raddypex]

Because 1 degree increments of Fahrenheit are equal to the volumetric increase of mercury by 1 part in 10,000.

[@ghulampirzada9983]

212superdude212 i have legit broken thermometers and played with mercury back when i was a kif its not toxic untit you accidentally swallow it but its vapours though can get in your body cause it is a liquid and evaporation is constantly occuring

[@whuzzzup]

Americans - especially younger ones - have this urban myth in their heads that mercury is somewhat the most evil thing in the world and you die when you look at it without protection, since they lack education. It's always fun seeing the comments of those teenagers under videos with mercury. This is why it's good that Cody shows them how mercury really behaves and that it is actually not really dangerous, you can even put it in your hands and nothing at all will happen.

[@MmeHyraelle]

I think this come from the weird "anti-vax" shit and thimoresal and mercury obscure propaganda.

[@RWBHere]

+Cody, Mercury thermometers can also measure higher temperatures than alcohol ones. Some are calibrated up to 360°C.

[@victorsantos9884]

Hey cody, you're awesome. Keep up the good work

[@user232349]

Note that calibrated thermometers are supposed to be completely submersed in the liquid. Not just the tip with the bulb, but also the entire stem.

[@USWaterRockets]

+CodysLab: If Mercury thermometers are illegal, how do you have them in your possession?

[@sno_crash]

I'd not seen a maxima/minima one like that. The one I've got has a metal needle in the capillary. It gets pushed in direction but not the other. To reset, do the same, couple of quick flicks.

[@DaHaiZhu]

My Dad had a mercury thermometer that had metal stops in it. So as the temperature went up and down, the stop got set and stayed at its highest point until it was reset (shaking)

[@arminasilginis]

Still use mercury thermometers in our labs here in Lithuania. :)

[@kohgeek]

I broke the mercury thermometer in my school 3 times...... They just put sulphur on the droplets. The students were curious what the silver ball 'bearing' on the ground was.

[@420weedle9]

I wonder if people could make Galinstan thermometers. Galinstan is a liquid metal alloy that is far less toxic than mercury but also has the high thermal conductivity of a metal. Its main downsides are it's kind of expensive and it has a relatively high freezing point, so the thermometers wouldn't be useful at very low temperatures.
