This feels a lot like OG Cody's Lab chemistry with the mercury and the gold - so much that I had to check it wasn't a reupload. I'll never tire of this kind of video
I don't usually comment, but this is an impressively information dense 10 minutes and not a second of it is boring. You're an exceptional science communicator.
Seeing the copper braid not taking the mercury versus taking it after an acid wash is basically how desoldering braid works, pre-doped with rosin flux, it gets cleaned as it is heated up (the flux is a mild acid) so the melted solder ends up wicking onto the braid, without that cleaning action, the braid is useless... :)
I wish I had such tools. I never seen copper braid sold and the though had not occurred to me. I would heat boards with a torch and or soldiering iron and pulled off a part. My friend had a suction thing he had bought from somewhere.
@@louistournas120it's pretty cheap online my guy though you won't get huge chunks like he's using there. Most places that sell soldering gear will sell braid, suckers and flux. The iron and solder are only one part of it
This is one of those things that most of us just never think about until we really need it: why does a cloth absorb water. We should probably ponder these questions more, because the answer is usually pretty interesting.
I work in hazmat and mercury spill kits have metal filings of some kind in them. It kind of made sense, but I never really understood why. Thanks for this.
4:49 I noticed that you mentioned the reflection issue. You can try using a Circular Polarizer Filter (CPL) to your camera lens to alter the reflectiveness of the mercury (or any reflective material) to your camera's view. Can also work for looking below the surface of a reflective lake.
Polarizing filters work for dielectric reflective surfaces like plastic or water. On those, the reflected light is polarized, and easy to filter out. But those filters don't do jack for metallic reflection like a mirror or a mercury surface - light reflected on metal remains non-polarized.
Never would i have guessed that the reason its being sucked into the copper fabric is molecular bonding. Provening it by removing the oxide layer is just so simple and awesome. Even when think i ubserstand a concept there is always more to learn.
Cody is truly a great educator. He's so good at explaining things simply, as well as relating to things we might have learned at school. We appreciate you so much!
All big TH-camrs make 10 minutes video and video is usually about one thing lasting 15 seconds. Not Cody's videos, his video is 10 minutes and everything is interesting and important
This was on my recommended and this was a great video. I found myself bored in chemistry class back in high school because I felt my teacher didn’t explain things well or visually explain (I am more of a visual learner) and this video made me understand this very quickly.
The way Cody conducts his experiments, and all the videos messing around with mercury from back in the day, out in his hermit’s abode in the badlands, feels like some kind of medieval alchemist who gained access to a carhartt jacket and video recording tech.
@@fmdj idk, alchemists didnt discover the philosophers stone in a tangible sense, but they did do some pretty whacky stuff that lead to explosives, refined glass making and all sorts of other breakthroughs. Cody seems to reiterate a lot of their greatest hits pretty well.
@@enricobianchi4499 what? no, lol it's toxic, especially its fumes (since it's a liquid it evaporates at room temperature), so it must be handled with care.
back in my old lab we had special hg absorbent paper rolls. dont ask me what they were made of but they soaked up mercury nearly as fast as normal rags soak up water. slower, as hg is havier but it worked quite well. though most of the time we just worked in plastic tubs and just recycled the mercury as unless you bring in dirt or anything reactive, it stay pretty clean for a long time. why did we do with it? it was used as a catalyst for ethanoic conversion (i.e. making ethanoates with metals to be used as catalysts for other reactions).
I haven't encountered such a thing. Would be interested in finding out how it works. I would guess it would have to alter the mercury surface chemistry.
All I can find is alloy wool and adsorbent powders. I guess one or the other could be integrated into a paper towel, not finding any results for such a thing myself though. EDIT: Sodium thiosulphate seems to be the main component of the adsorbent powders, if it's possible to dope some paper towels with that, perhaps that would work?
Most of us would never be able to do this experiment ourselves, so we'd never have gotten to see that awesome shot of the gold sucking up the mercury. Thanks so much :D
I'd guess that the high surface tension also plays a role, although I don't know how it would change it. Mercury has a surface tension of nearly 500mN/m, much higher than water's (73mN/m) and far higher than other common liquids.
The main reason that the rag "absorbs" the water is due to capillary action/effect, where the surface tension (and the polarity and the surface material and cohesion forces &etc) causes the liquid to rise or flow into the material (in this case, the rag). It's generally easier for fluids with high capillary effect to move into materials with smaller pores, such as fabrics or soils. Mercury exhibits a negative capillary effect due to its' metallic cohesion being very high. Which is alluded to in the video. You can see this visually as mercury forms a convex surface (look at the edges of the vessel!) whereas water has a slight concavity. It's already climbing up the edges. Therefore mercury won't enter the rag without assistance (i.e., the rag is made of chemically cleaned copper).
Yeah me too! Hey also check out "Chemdelic" and "I did a thing" they are both almost as cool as this. I like the way he makes it easy to understand even if you aren't a scientist. My best mate has a masters degree in chemistry and I got him to verify all four of these channels and he said that they are all legit so I know I can trust them. Making out like a bandit with knowledge!
@El-xt9oo tested out og HS at 16 never went, and was pulled out of public school after 6th grade due to massive bullying that the staff, teachers,and councilors blamed me for.

My mom pulled me out homeschooling me, and I was able to test out of school and start community collage. Just never took chemistry
@@isaiahoconnor8236 I used to drink with my chemistry teacher at the bars and clubs at night, I was not allowed to call him "Herbie" at school. Chemistry was after lunch and lunchtime was when a lot of weed got smoked. Sounds like we were opposites but what we have in common is that we missed out on basic chemistry!
May I introduce you to Nile Green 😎 (He made some parody videos with consent from Nigel, and later rebranded to MrGreenGuy and switched to making actually chemistry videos, but just a tad bit edgier than the rest. He showed how he keeps safe and what not to do, but YT is definitely punishing him badly right now)
I remember watching a show about gold mining in Africa, where mercury is routinely used in the gold revovery process. One of the things they would do is collect their fine gold concentrates in a rag and pour mercury onto their gold, then clost the rag into a wad and ring out the excess mercury. This would leave a gold-mercury analgam that was solid enough to carry around for future refinement. It is reminiscent of what Cody was describing with the copper weave, but in this case it was gold dust with a normal fabric outside acting almost as a mercury sponge.
i like the cut containers to hold mercury, and the bottle cap with HCL slowly wafting scary fumes off the entire time. Makes you feel nice and cozy and at home in a Cody video.

In 6th grade the science teacher gave us all some mercury to take home and experiment with. (The 90's were a much cooler time to be around.) One of the things I noticed was that it wouldn't soak through fabric, so one of the experiments I did was to pour it out onto my bed and just kind of tug at the sheet, watching it roll around, split into multiple droplets, then join back together. And then....bloop. It disappeared. All of a sudden, it soaked right down through the sheet. I stared at it for a couple seconds, then lifted the edge and had just enough time to see the blob soak down through into the mattress itself. And that's where it ended up, presumably staying somewhere inside that mattress until we moved 2 years later and it got tossed.
@@silentwraithgaming8631 Yeah? Copy that. I use vinegar or really diluted bleach every couple of runs. I had visions of shiny brand new looking copper. Could someone explain why I'd be making a mistake? I'm new to shining, only been at it for a couple of years and still have a long way to go. The Copper Age is new to me. Thanks for the advice, I won't do that.
at 0:50 I can't be the only one seeing, as if responding to "That's pretty cool, right?" a solid "yes" marked in the surface of the mercury.
Replayed it many times lol I really can't see a yes in the mercury
I see a big S

Classic Cody's Lab 👍
It's honestly incredible how much you can teach with just the one question "why does a rag not soak up mercury". You are THE best science youtuber
i wouldnt say THE best
Hard to pick 1 science TH-camr who is the best when there are so many good ones. Cody is definitely S tier though
I miss these videos
Look up Bruce yaney he's good to

No surface tension would only make it slower, not affect the over all ability. The video is absolutely correct in saying it’s a metallic solvent
Did you see how the gold sponge soaked up the mercury?
Yeah, I think I mentioned, it has to be able to stick strongly enough to overcome it's surface tension.
The main reason that the rag "absorbs" the water is due to capillary action/effect, where the surface tension (and the polarity and the surface material and cohesion forces &etc) causes the liquid to rise or flow into the material (in this case, the rag).
