I hate flies.
Why does the fly force a restart?
Everyone hates them, they are annoying.
nurdmage
come to Australia in the middle of summer, we have no flies here **snickers**, well actually, if you hate flies, come in the Winter :)
Musquitos are worse lets be honest
Love the lab notes series. It feels much closer to actual science than other similar content out there. Can’t wait to see the next one.
You should check out NileRed then, he is even more professional and you would probably like him if you like lab notes
"Flies ruin science" should be a t-shirt. If you ever make merch.
Or a t-shirt with a picture of a flask halfway full of liquid and a dead fly at the bottom with the words "Well f... you too."
Picture of Jeff Goldblum on it. 😎

Unless it's biology, in which case, they're important, especially in genetics.
Hi! I'm a year 10 chemistry student in Hong Kong, and you're my favourite chemistry RUclipsr! You don't really help me improve my grades since your experiments aren't in the usual secondary school syllabus, but you always remind me about what's so fun about chemistry! I forget that sometimes when I'm stuck in the boring hell-hole of homework.
I'm totally not praising you so that I can get that molecular modelling kit... although that would really help me with my studies
Tetrahydrolinalool, a saturated branched tertiary aliphatic alcohol, is available for $14.50/100g from The Good Scents Company, among others. It's used in perfumery.
This channel is on my list of recommended viewing for my IGCSE chemistry class :)
I don't get why the fly made you restart the experiment..
Contamination
Have you never seen superhero movies ? That's how bad things are created. Do you want a massive drunk flying ball of Sodium with super powers roaming the Streets?
oh i definitely would want to see something like that, but from quite far or as you said in a movie :>
in nurdrage russia fly swats you
it's aesthethicly displeasing
One of the best videos so far; I like the way the experimental 'thought' is explained. The best chemistry on RUclips.
that is a really cool molecular model kit!
Your response in the first video where you got pissed about the suicidal flies literally had me laughing out loud. My daughter appreciated your humor about the situation as well.
I never took chem in school, but I always had the curiosity. Watching the content on this channel for years has been fulfilling for me
The primary component of tea tree oil is 4-terpineol, which I assume is the tertiary alcohol you're after. The primary component of pine oil is alpha-terpineol, an isomer of 4-terpineol. Would it be worthwhile to try that as well or would you expect the two to have similar properties?
Probably nice idea would be to check other terpenoids with are tertiary alcohols. There is some that should be quite easy to obtain. There is Linalool, and definetly others.
So what are the upper and lower limits on the amount of the Tertiary alcohol catalyst needed for the process?
Your reaction to the fly was possibly one of the funniest "chemistry" things I've ever seen. Keep up the awesome vids man, they're top notch!
I really enjoy the Lab Notes Series. They keep everyone updated on the big picture, otherwise there would be fairly long periods between videos. There is also a lot to learn when things don't go exactly as planned, like the need for paper towel to keep out suicidal flies.
What came to mind: since the amateur chemist for whom this scenario is supposed to work should have access to magnesium and presumably acetone: do you think using pinacol as a tertiary alcohol is worth a try?
Anyway, great vid, loved seeing the progress!
According to Wiki, HgCl2 is required in the coupling from acetone? Any better and safer substitute?
CdCl2
As promised in the previous lab notes video, I'm still working on making pinacol and testing it out in this reaction. So far what I've learned is that dry acetone and mg shavings do indeed react at room temp to produced pinacol, but the amount produced is presumably very low due to slow reaction. I've added heat as well as an Iodine crystal to try to speed things up, and the reaction is progressing albeit still slowly. At the end of 3 days of heating at 50°C I will stop the process and quench the mg pinacolate with water and see what the yields are.
I've also gone ahead and purchased mg shavings from a different seller because I have a feeling that the ones I'm using now aren't pure magnesium as promised but rather some low-quality alloy. So will try this process again when the 95% mg comes in. I'm also working on making pinacol from lithium and acetone, and that reaction actually proceeds quite readily at room temp with heat generation. However, my reaction mix has turned gunky yellow so I'm thinking impurities in my old acetone are polymerizing, so will be buying a fresh bottle of acetone and go from there. Wish me luck!
@@snowdaysrule nice, keep us updated :D
@@snowdaysrule Good Luck sir.
That fly just wanted a molecule kit.
You can tell when you're right into something. You're usually hesitant to waste time and chemicals for forgone conclusions, for this series you're trying all the angles! Keep up the great work!
The #1 all time best chemist on youtube. A real tribute and role model to the sciences.
When are you going to do some experiments with fly catalysts?
Wow. Not only am i early, the time is early. It’s *checks time* 3 in the morning. Science>sleep huh?
For sure
What is this magical thing you call s-l-e-e-p? Care to elaborate?
Always :)
No sleep when there is science to do!
As a theoretical chemist, I can only marvel at your experimental expertise. Keep up the great work.
I don't want the kit, just want to thank you for your lab notes, they are super cool. Showing not only the bright side of your experiments, but also mistakes and failures was the best decision.
Chemistry was my thing in high school, then programming completely took over my brain, so I gradually lost much of interest in and knowledge of the former. But even being a layman now, I still enjoy learning things here and there about chemistry, especially about the experimental side of it. Knowing the equations can only get you so far, making reactions work is not as easy as it looks, as it turns out. Your videos show that perfectly, that's why I love them.
Did YΘu Anger The Fly KingdΘm Θr SΘmething? This Is Getting RidiculΘus!
Greenlightning what’s with the thetas?
@@SpycyzygyI Think They're Real Neat.
Comment in the Description...
Shameless grab for the prizes! 👍🏼
The lab notes format is awesome! Not only does it illustrate and document your process, it really shows how much time, and effort goes into developing a process like this!
Am I the only one who really enjoys these lab notes!?
Love your videos, I've been watching for maaaaany years!
you should really put up some fly paper, theres been too many suicidal flies attacking your experiments
also
gimmie kit

If you give me the molecular model kit, I promise I will not swallow them
Shitting them out would be like anal beads 😂
The joy of eating magnets.
It's nice to finally know the real purpose of those molecular model kits. Best of luck refining that tea tree oil, and ramping the overall yield percentage back up into the 90s.
I've been following this series on the Sodium recovery for so long... man, this has been a long trip! Watching the discoveries, the failures, the successes, the breakthroughs... thinking that you've got so far with your research is so...refreshing. keep up this work man, I want to see the good end of it! Also, those molecular models.... they are cool!
The worst part of giveaways like these is that people comment just for the items in question, diluting real discussion.
That being said, this is a RUclips comments section, so there isn't much discussion to be had here anyway.
I disagree. Some of the best, most civilized, and thought-provoking discussion occurs here in these RUclips comments.
Seconded.
I've had some good discussions with commenters too.
Including people admitting they were wrong.
True story.
Solution: after randomly picking a winner, review all his comments to see if they're really into the discussion, not just leaving random comments. If no, pick another one until you got the real one.
I wish that fly was me
It wouldn't be Nurdrage without the files! Absolutely in love with you, incredible work!
Although the longer, full-process videos are really interesting, I think that this Lab-Note videos are one of the things that currently makes this channel stand out from the rest of chemistry/science channels... I love this format!
You will get 10kg of Na at the end...
He can throw a sodium party!
Yes the final video on this channel will be Nurdrage throwing his 10m ball of sodium into a lake and ending all life on the continent

*this is a reply*
This is a chicken wing
loving all the updates!
Thanks for the update. Your progress is inspiring.
Thanks for bringing us all into your lab, and letting us be a part of this chemical detective story - you're making great science, and great videos.
This series exemplifies one of my favorite things about chemistry: you can do all the math you like and work the stoich until your eyes bleed but sometimes you need to just mix stuff together and see what happens. And even then as long as you document your results it's not "messing around" it's science.
As always, incredible work NurdRage!
Love seeing the progress.
I remember one of your blogs that you told about failed experiments being boring etc, but I think this Lab Notes format, with failures, small successes is really great. Now we are getting real insight of how does chemical research look like in VERY practical manner, with failures, tries, messing with parameters and checking with extremes if it even has a chance of working. Not sure, but I might like more those "in progress" vedoes than ready to use recipe video.
Your videos is always a joy
This has been a lovely series!
Bless you for taking the time to do this. The molecular model kits are pretty awesome.
Great job my friend! Please keep up this great progress!
Love the recent surge in activity on this channel, keep it up!
Good Work again!, always a joy to see your work. Those Molecular model kits are very nice btw
These videos are great! Been watching you for years and I always love to see your experiments
Everytime I see a new video I get so excited to see what more you've discovered!
love those kits, love the lab notes series. keep up the great work!
awesome to see this project come together ! exited to try it myself some day
Much enjoyment from this research series. Thanks for all the hard work and most of all sharing with us!
Great vid. Love that you left the fly in!
Been loving seeing this whole process unfold. It’s been a fun a very educational ride. Can’t wait to see what you come up with next.
I absolutely love this series, you're part of the reason I've realized I love chemistry, and projects like this are so rewarding to me to watch. Very insightful, and not terribly difficult to follow. Great stuff!
Really nice model kit. Love the multi bond feature in the atoms.
Amazing progress, well done!
This is easily the most sciencey youtube channel I'm currently subscribed to. The only one that regularly does systematic research anyway. One day I hope to be able to perform useful amateur chemistry research myself.
Keep up the good work. Ive feen following this process since your first vid. Great work and discovery. Thanks
These lab notes are so interesting to follow, can't wait until the next one!
I love the lab note series! Being able to see all the avenues explored is invaluable!
I like these lab notes, you take us all through the whole research process and teach us all valuable things
Long time subscriber. Love your content man. Keep up the good work!
Love these videos you do. Thank you for educating us all and encouraging the love for chemistry!
Glad to see the experiment progressing, its been quite interesting to keep up with it! Hope to do this on my own in a few weeks.
I've been watching your videos for a couple months but I had never subscribed. I realized this at the beginning of the video and am now a new subscriber.
I've enjoyed watching this series play out in real time and seeing the progress of elimination used to learn things in chemistry
This has been a great video series. I always look forward to seeing your next video. Watching your channel got me interested in learning more about chemistry. Thanks!
I am so glad I caught up on the lab notes. your potassium video was one of my favourites, and this has been an awesome journey to watch
It is really nice seeing the different approaches to the problem.
Yo I'm glad you do this kind of thing makes my day every time I watch a video
Always enjoying your videos and the information provided in them.
I make a point to have a hard copy back up just in case.
Thank you for the work that you do.
Love to see progress on research!
Really cool stuff, hope to see the full video soon!
Great series. I’ve been learning a lot.
I love these lab notes videos. Keep 'em coming.
Thanks for posting these labnote vid's. Research is a time-consuming, humbling and sometimes fly infested practice. Keep up the good work!
Thanks for all your work.
While not a chemist, I find listening to your videos make me feel smarter.
Love these lab note videos. Keep up the good work. Can't wait for you next video.
Those kits look awesome!
You know it’s gonna be a great day when you start it with a Nurdrage video (though this is sometimes canceled out by lack of sleep due to a chemistry lab report of all things)
Awesome video as always, keep it up man! Also those molecule kits are super cool wow.
I must say some of the favorite content I see from you are these big projects. The synthesis of pyrimethamine was great to follow and I'm enjoying this project too.
I really like this lab notes format
That kit does look awesome!
Love your channel! I started off wanting to be a chem engineer, but a string of horrible professors turned my interests to mech engineering.. your channel and humor is reigniting my love for chem! And im sure im not the only one! Keep it up
I admit i haven't been keeping up with your series as much as i would like but i love the chanel. You are an inspiration to chemists.
love you work. Ran into an issue with RUclips again not putting your videos in my subscription page but I always check your page directly to get around this.
Anyhow, keep up the amazing work. Always a pleasure to see another fellow research chemist at work.
I love the lab notes series. I feel it goes more in depth about some of the problems had during reactions.
Loving the lab report series!
I love watching these videos cause they always make me look into new types of reactions so I don't get rusty on my chem
Really liking these semi regular lab notes. I'm not likely to use the final procedures anytime soon, but I do enjoy watching the experimentation and learning some things on the side.
I really like this format of videos, keep it up please.
Great video. That molecular model kit is really cool too.
Thank you very much for all your videos. They are both immensely entertaining and actually rather helpful for me, as I have just started studying chemistry more seriously.
Thanks for another thorough chemistry video.
