You guys wanna know how dedicated this guy is? I just looked up where he gets his samples from, and a 1 gram pellet of Rhenium is $40! The amount of money this guy sinks into the material for these videos is definitely worth a like! Major props, Brian
I love how this video makes a clear documentation of the scientific method and the mathematical analysis of the results. More science on youtube needs to have this kind of rigor. I loved the video, good job!
SoopaPop Yep. This guy is good. I was aware of the magnetism of cobalt, iron nickel and gadolinium, as a result of experimentation with my element samples. But this floating test was a great idea that illustrated magnetic properties of many other elements that, I think most of us were probably unaware of. None of this was taught in my school. I graduated high school thinking that only iron would attract magnets! Lol
Thank you!! I can't tell you how many times I've had to correct people who believe that Platinum and PGMs are not magnetic. Especially among the buyers of ore and processed metals i deal with.
Many years ago when I was a chemist I set up a method to measure diamagnetism using a four figure scale. We had a U shaped piece of plastic machined up and at the top of the U we placed two powerful magnets that were attracting each other. This set up was then put on the scale and the scale zeroed. The sample was put in an NMR tube and slowly lowered down in between the magnets. The maximum reading on the scale was proportional to the diamagnetism of the sample. I recall it being surprisingly accurate I'm guessing because the magnetic flux between the two magnets was very high. I can try to draw the apparatus if you need.
So the scale is holding the weight of the magnets too? I guess two smaller magnets with opposing poles would make a powerful magnet field for small samples inbetween. Thanks for the suggestion :)
Yes, the magnets and the frame holding them apart are all on the scale. I was using a 4-figure balance which has a maximum tare weight of 500g (IIRC). That's easily enough for two decent sized magnets. I seem to recall the magnets were about 30mm diameter by 10mm thick. This was years and years ago though so we were probably limited in what we could get hold of. I would imagine the parallel field lines in this set up help with measuring diamagnetism as the generated force would be entirely perpendicular to the sample. An NMR tube is perfect for the sample too as it's very thin glass and you can buy holders for them. I was measuring powders of metal containing complexes, solid metals might be better just stuck to the end of a stick :-)
OK - my scale only holds 20 g in all, so it limits the size of the two magnet too much. But I may try to lower the two magnets with opposing poles and having the sample steady on the scale - should give the same result.
Ruthenium is a fun element. When I was in school, we used some with an organic ligand to make a photoluminescent compound which would be quenched by diatomic oxygen. We embedded some in clear silicone rubber and could measure dissolved oxygen content in water by reading the intensity in response to excitation by a blue LED. It was my second favorite project in that series of labs since it brought together so much chemistry and physics.
Brainiac75 Synthesis of CdSe nano crystals (quantum dots) via Ostwald ripening. The big interest at the time was attaching them to proteins and tumors to assist in kinetics study and improve medical imaging techniques. I had the idea of gluing a medley of various sizes to a then-new blue LED as a mean to produce a then-yet-uninvented white LED but my professor didn't think it would work. I found a few months later that another group in another university received a patent for basically the same idea (given the timeframe, they had prior art to the idea. c'est la vie. :))
ExaltedDuck Oh yes, I did come across CdSe when researching for the fluorescence video. Including the use in LEDs - bummer for you :( I may need to make a video about CdSe in the future. But I guess its toxicity limits its availability.
Our synthesis involved benzenethiol to make the precursors. I would recommend against using that outside of a well equipped laboratory. Even just a little bit gone astray lingers for days, and its odor has a slightly smoky and pungently fecal quality. =D
@ExaltedDuck Definitely a fume hood project then. @Brainiac75 You might try asking NurdRage if he knows of a way to synthesize it from chemicals that are available. Cd is available from poisoned (dead) NiCd rechargeable batteries and Se from the toner drums of used laser printers and photocopiers, and many dandruff shampoos.
I greatly appreciate the detail you put into each video. You also make sure there's a ruler for your viewers reference. You always put the bottle of the metal your testing next to the test. You even put a Lego finish sign at the end of the speed test. Thanks for taking time to add the little details that make all the difference!
Thanks for noticing the small details. I believe you would like my other videos too, since I do try to put a lot of work and thought into all of my videos. No daily or weekly mainstream videos from me ;)
Amazing how accurately one can analyze elements and their properties with relatively simple and inexpensive equipment. Knowledge truly is power when wielded properly.
Very interesting. I don't know that I've ever been aware of the properties of paramagnetism and diamagnetism. If so, I've long since forgotten about them. Thanks for teaching me some awesome stuff!
Thank you so much for providing amazing videos for over a year as I have watched you since 3k or less! Your videos are amazing and are very interesting. Thanks for the Christmas gift!
I have those same gold spoons! The plating is so thin it started wearing away almost immediately. Thanks for the video. I like seeing large hunks of pure elements and getting a sense of their mass properties.
I can't understand anyone giving a thumbs down to a vid that is just the presentation of raw facts? As a friend of mine would say, "haters gonna hate".
yeah. i hope my videos reach that quality. and you are a scientist as long as you record it. (d2rormqr1qwzpz.cloudfront.net/photos/2015/12/15/83986-83931-05-mythbusters-expressions.jpg)
Really nice demonstration. Some inexpensive techniques for scientific investigation of a very interesting property of materials, which anyone can do at home.
Excellent video!!! Exactly what I was looking for. I am thinking of two applications. One is to separate precious metals from automotive catalysts. Pulverize, swipe a magnet and voila! Another one for investors - to authenticate gold and silver coins and bars, which are prone to be counterfeited with, for example, tungsten.
It does look a little off center. I may have been able to get a couple of milligrams more out of the gold sample with a better centering. Thanks for watching :)
this has been great I caught all 5 of the vids at one time.. please do more if you can.. these were very very interesting.. makes me want to collect all of the elements of the periodic table for a display..
Once again, top quality work. Your patience is way better than mine. I would have gone mad if I had to repeat each test ten times! Have a Merry Christmas, New Year and put your feet up for a well deserved rest :) Cheers.
Hehe, it's only 90 test in about an hour. Nothing compared to the probably 70 hours put into this video in all... Merry Christmas and Happy New Year to you too. It's been a good year.
I watch your videos before I go to sleep. I find the information is absorbed well before sleep. very interesting videos. I really enjoy your simple and effective presentation of your videos, it's a breath of fresh air compared to some other science channels. This seems more honest and less cringe. keep it up señor I do enjoy them. You do a great job. I'd like to see more videos on the physical properties of magnets in electrical equipment. Merry Christmas! regards Dan
Yes I do like this video I am going to have to go back and watch the first 3 I came across this looking for something else and it peaked my interest and curiosity. I'm glad I stopped by.
if you did part 1,2,3,4,5 you must do part 6 i'm not fun of magnet stuff but hey a good video is a good video, it does not matter what it's about really i think
It's always fascinating to see the 6 different kinds of magnetism. In another video maybe, could you explain how superparamagnetism works for those who may not know what it is? Normal paramagnetism is my personal favorite kind since it makes paperclips stick to other paperclips. Diamagnetism is cool though as well since it levitates things. Why it actually happens though is really goddamn complicated
Magnetism sure is complicated and difficult to explain. Hard to apply our daily logic to the quantumm mechanical effects from electrons :\ I may give it a try in the future - thanks for watching!
Antiferromagnetism has a bunch of atoms or domains of atoms generating magnetic fields opposite to the atoms or domains beside it, cancelling them out and producing no net force. And example is Iron III oxide: Ordinarily it is antiferromagnetic. You can heat it to above it's Néel temperature though, and it will become paramagnetic
Gi tirado Chromium is interesting since its Néel-temperature is just around room temperature (where it changes from antiferromagnetic to paramagnetic). I may have to try to cool/heat chromium in a future video to see if I can spot any changes in the magnetic susceptibility. In my table I used the value from CRC Handbook which should be around room temperature.
I love how you utilize legos in your videos, I use contraptions in real life all the time too! I'd love to see pt 6, but understand funds being the factor. Especially when UA-cam these days seemed to be turning off money from videos. I love the gold spoon bit at the end, very clever!
Your video really deserve to be best video regarding meassuring the intensity . . Most I would say sphere process you shown is best way to make the perfect reading to element attraction 🤩🤩🤩🤩🤩🤩👍🏻👍🏻 nice outstanding video
I always enjoy your videos and the detailed physicist's sort of explanations. Myself I am an electrical engineer and I always crave expanding my knowledge of how things work and material properties. I learned something new today about silver when watching your videos as an example. Many thanks. And Merry Christmas to you.

+Firefox - you obviously didn't watch the whole video.
Wood 'n' Stuff w/ Steve French You must not have.
Brandon Clifton - No... I watched the entire video. Including the part where he asked if we want a 6th part. Did you?
I'm a firefox.
Cyanide and Happiness reference.
There are only rubidium, strontium and tecnecium in the rest

That's some good lateral thinking. Perhaps you could crowd fund a set of accurate scales. Looks like you can get a 0.1mg accurate scales fro

I've never seen a video from you that wasn't worth a like.
Agree
Thanks for your continuous support, Ben. Didn't recognize you at first with the new profile picture :D

your vids are so informative and most importantly... not boring!
Very interesting. I don't know that I've ever been aware of the properties of paramagnetism and diamagnetism. If so, I've long since forgotten about them. Thanks for teaching me some awesome stuff!
Thank you so much for providing amazing videos for over a year as I have watched you since 3k or less! Your videos are amazing and are very interesting. Thanks for the Christmas gift!
Yeah.. part 6. We all are waiting.. Keep up the good work.. We all are magnetically drawn to your channel..
i am screaming with joy inside
you watch him too? weird lol.
🤣🤣🤣🤣 same here
Ya I find this stuff everywhere going to be purchasing bulk magnets 🧲
I have those same gold spoons! The plating is so thin it started wearing away almost immediately. Thanks for the video. I like seeing large hunks of pure elements and getting a sense of their mass properties.
Really cool what you're doing here. Great to see these measurements done in a way that makes sense as to what exactly the measurements mean.
This is concisely explained, and should be taught in all schools.
Thank you for this.
Yes, part 6 please!
Super informative! and the caption help me understand much better. Thanks!
No problem - thanks for watching :)
Nobody does this. I have a feel for this group of elements now.
Thank you
I can't understand anyone giving a thumbs down to a vid that is just the presentation of raw facts? As a friend of mine would say, "haters gonna hate".
i absolutely love the fact that you are super scientific but still use the same (great
) interlocking brick system as used in toys
Hehe, I'm not a scientist but a science fan. And why not use Lego for the experiments - it's so universal :) Thanks for watching!
yeah. i hope my videos reach that quality. and you are a scientist as long as you record it. (d2rormqr1qwzpz.cloudfront.net/photos/2015/12/15/83986-83931-05-mythbusters-expressions.jpg)
I now understand what is para and dia. WIKI blows my mind away and your experiments blow it back again. (Plz let part 6 shown on UA-cam)
I have learned more about elements from this series than I have in public ed and uni. Wonderful info!
Great information, interesting how metals in the same category have such diverse results.
Really nice demonstration. Some inexpensive techniques for scientific investigation of a very interesting property of materials, which anyone can do at home.
Excellent video!!! Exactly what I was looking for. I am thinking of two applications. One is to separate precious metals from automotive catalysts. Pulverize, swipe a magnet and voila! Another one for investors - to authenticate gold and silver coins and bars, which are prone to be counterfeited with, for example, tungsten.
I kinda like how you actually updated the periodic table to the new names of the artificial elements.
Yep, that's one of the changes happening in the 4 year span of this video series so far. Thanks for watching!
liked the information about each element as you tested their magnetism
You weren't centered on the gold push/pull test, CLEARLY. I should think it makes a difference? At any rate, a brilliant show and thank you very much.
It does look a little off center. I may have been able to get a couple of milligrams more out of the gold sample with a better centering. Thanks for watching :)
I can not wait to see part 6 and beyond. :D
This series is fantastic. LOVE the chequered flag in the stop watch test.
this has been great I caught all 5 of the vids at one time.. please do more if you can.. these were very very interesting.. makes me want to collect all of the elements of the periodic table for a display..
Super cool that you are saving up all this money and not asking for money
5:30 - Thank you very interesting table
Amazingly thorough research...
I love how cleanly you edit your videos mate
Alexander Martínez Pasek thats why it takes a lot of time to produce a video like this, quallity matters.
Yes, I would love to see a part 6.
super cool stuff. This is the first of your videos that I've seen, and I'm very impressed.
Nice - thanks for watching :) More to come.
This is really cool, and the diamagnetic stuff blew my mind. Good work!
Thanks for watching :)
Once again, top quality work. Your patience is way better than mine. I would have gone mad if I had to repeat each test ten times! Have a Merry Christmas, New Year and put your feet up for a well deserved rest :) Cheers.

Brainiac75
Oh I fully understand the extra time taken in making the "whole" video, but still, doing those tests Ggggrrrr. All the best :) Cheers.
Yes, Part 6 would be wonderful!
Another exotic elements video, Waited 1 year, and it was definitely worth it ;)
The creativity with legos and models you used to measure magnetic force are pure genius. Oh and of course we want part 6 :)
"Oh, sh... plashing water!" ;)
lol i was curious as to what this comment was about now i know lol
Ah, I see you've changed your profile picture.
I love these videos in general but for me the best part is the end where you let loose and have fun
Thanks! I try to balance being serious and entertaining in the same video :)
You are entertaining and adjucatina and that's why I watch your vedio s from Iran with VPN
Iran! Don't remember ever having a comment from your country. Great, that you have found a way of watching UA-cam :)
The best christmas gift: one new creative video from you :D
I was so excited to see part 5 show up, can't wait for part 6, and maybe 7 and 8
Wow,all the time it took you to film these experiments, and I've just gorged myself on them in one go. Brilliant, thanks. 😁
**Going to the jewelry**
I want 3 Au's please.
Fun joke
あうあうあう
Au. Au! Au!! Is that better? ;-p

Thank you very much, Dan! Much more to come and Merry Christmas to you too :)
You have great videos. They're a pleasure to watch.
Fascinating .. Wondering how to capitalise on this knowledge!
Clever, clear demo. I would love to see part 6!
You didn't have to ask for a thumbs up. This was worth one imo
You have the most amazing channel . Thank you
Yes I do like this video I am going to have to go back and watch the first 3 I came across this looking for something else and it peaked my interest and curiosity. I'm glad I stopped by.
my god, this is truly amazing! thank you so much for such an awesome time of learning about the elements. :)
please do part 6!
Thank you very much :) Part 6 should be possible.
Nice. Totally looking forward to part six.
Really exciting and excellent experiment
Always love to see these videos once in awhile would love part six
I randomly stumbled onto this channel. Very cool stuff, subscribed.
Nice :) Welcome aboard!
Bravo , just Bravo mate. keep it up !!!! Very nice stuff and amazing narration!!!!
Thank you very much :o) Much more to come in 2017.
Thank you!!! Part 6 please...you got my like❤
if you did part 1,2,3,4,5 you must do part 6
i'm not fun of magnet stuff but hey a good video is a good video, it does not matter what it's about really i think
I like your samples of elements. Something I've always wanted to collect myself.
A great demo with great info
You deserve 2million subscribers

perfect! as always ! love to see the part 6
you are awesome my friend! one of the best youtube science channel!
Thanks for your continuous support :)
Wow even youtube gives me christmas presents! Great video as always, Brian. :)
Hehe, this video is my little christmas present to you all. Thanks for always watching!
Keep up the good work and Merry Christmas
Well. Just saw the whole series as well as 2 other videos. I look forward to your future videos. :) Subscribed! Very high quality content.
That's awesome. Welcome aboard :) Much more to come.
Thanks for sharing your research with us.
Absolutely superb videos!
Love this video. You did a great job. Thanks for this info. Who would have guessed so much fun can be had exploring metal properties. Awesome.
Yes we all want Part 6 👍🏽👌🏼
If you keep making these vids I'll keep watching I totally enjoyed these
Thanks - hope to make part 6 here in 2017 :)
looking forward to it. really kool hobby I must say
You Rock Bro ! Keep Exploring with Science your journey will begin again and again; Science Rulez!!
yaaaay the periodic element table has all the names!! good job!! you got a sub
Thanks! Welcome aboard :)
Excellent science display, thank you :)
Wonderful job, man. Congratulations.
I really enjoy your videos!
I love how you utilize legos in your videos, I use contraptions in real life all the time too!
I'd love to see pt 6, but understand funds being the factor. Especially when UA-cam these days seemed to be turning off money from videos.
I love the gold spoon bit at the end, very clever!
Merci pour ces expériences rigoureuses, simples et sans danger!
excited for part six
Definitely hoping for a part 6. Didnt even know diamagnetism was a thing before your videos
Part 6 will come sooner or later - I just haven't got more elements to show right now. Have a little patience and thanks for watching :)
Your video really deserve to be best video regarding meassuring the intensity . . Most I would say sphere process you shown is best way to make the perfect reading to element attraction 🤩🤩🤩🤩🤩🤩👍🏻👍🏻 nice outstanding video
Thank you, this was very interesting! ☺️
Perfektné a zaujímavé🔆
I always enjoy your videos and the detailed physicist's sort of explanations. Myself I am an electrical engineer and I always crave expanding my knowledge of how things work and material properties. I learned something new today about silver when watching your videos as an example. Many thanks. And Merry Christmas to you.
YES!!! Part 6!!!! Tungsten filled gold bars!!!!
A very unexpected, yet a very good video
Part six please love your element vs magnet videos
:D
I would love to see part Six!!!
GR8 video, informative
would enjoy watching your new videos,too, thanx.
thanks braniac75! your videos make me feel great.
Fantastic episode continue with more please
