They used enough spider silk (over 300 strains I don’t recall) but they were both the same amount of mass/weight. Both did the test and the silk held more water before it snapped then the steel cord.

[@echo8083]

Ancient Greek myth about spiders: There was once a woman named Arachnid who was incredibly talented at weaving and looming. Her talent was so great that people compared it to that of Athena, goddess of knowledge and arts. But Arachnid was too proud of herself, claiming her work was better than Athena's. This angered the goddess, who transformed herself into an old lady and went to Arachnid to see if she'd back down from that statement. When Arachnid did not back down, Athena turned her into a spider. But Athena did not take away Arachnid's talent, and so this is why spiders are so good at weaving beautiful complex webs.

6:59 Objection: There is something (pardon my translation, heard that in a german lecture on material science and can't find the source material) "Second paradox of material science" or something like that, which states that first, materials in string-like shape are stronger (in the sense, that they can withstand higher forces per area before failure) compared to beams and also: the smaller the area, the higher of strength (force per area) for the exact same material. If I remember correctly, it has something to do with errors in the material, where in objects with great area (and therefore, great forces for the same applied tension) errors in the material tend to grow faster. But please: correct me if my explanation is wrong or if you can add in more details Edit: Source: A. A. Griffith From the german wiki article: "A material in fiber form has a much greater strength in the fiber direction than the same material in another form. The thinner the fiber, the greater its strength. The reason for this lies in an increasing rectification of the molecular chains with decreasing available area. In addition, weakest link theory ("Each chain is only as strong as its weakest link.") are distributed over very large distances in the material, so that the fibers are largely free of defects that can cause a break. Since material can then be saved with the same strength, a material with a high specific strength (ratio of strength and weight) is created. In addition, a defect in the material does not lead to the failure of the entire component, but for the time being only to the breakage of a single fiber in the composite (no crack propagation)."

[@kaitlyn__L]

This is a big problem with growing carbon nanotubes, as they’re only strong when they’re very short and defect free. Composite materials keeping the fibre in fibre form within a resin carrier (fibreglass, carbon fibre) are an attempt to mitigate this relation of shape to strength, which will probably also be done with mass produced spider silk. Of course that’s not perfect as these composites are also often more brittle than the bare fibres free to move in all dimensions.

@@jameswilson8907 in my childhood home there was a roof window atop the staircase, too high for any dusters (even the long ones) to reach. Naturally, being a window, insects flew into it. Naturally, a spider set up home there after they noticed the bugs. So, all the shed skins just slowly collected on the web, and the web was pretty much the size of the entire window. So there was a clear visual history of its growth, and you could see the growth plateau and merely maintain existing mass after a couple years. After 4 or 5 years, new skins stopped appearing. I suppose the corpse was up there too. As far as I know, that remained until we moved out, just because it was so inaccessible for cleaning. But it had grown by an order of magnitude from the first sheds, and interestingly it seemed to have tried to roughly organise them after it had noticed the first few building up.

So theoretically scaling doesn’t matter for tensile strength, but we know that imperfections can dramatically lower strength, and so having a very small cross section with few chances for defects (like a strand of spider silk) could partially explain the silks strength. This is one of the principles behind super-strong nano pillars. Have people tried to analyze how much this defect probability matters to the fibers’ strength as opposed to what it would look like if we scaled it up to a bulk material?

[@antaresmc4407]

Actually, the web strengthens and stiffens as strands break up, as the crystalline links kinda get clogged in between, difficulting further strain of the more flexible amorfus links. I dont know how strong is the process or much about how it works, but its great to maintain structural integrity after high impacts. It is basicly a very efficient work hardening afaik... Tbf the architecture of silk is precisely made of thousands of microscopic threads, effectively having that simillar crack growth resistance as nano pillars or whiskers

tension is the pulling apart forces and compression is the pushing together forces, concrete has high compressive strength butneeds metal supports throughout to give it tensile strength

I actually started watching this on Nebula, but the streaming speed was too slow and video kept pausing and pausing. Then I switched here and I could watch it with no problems, so the connection issues are definitely problematic on my side... This is not a first time - it's happening for several months now 😞. Fortunately, by watching it here I now got a very good recommendation for a documentary to watch on Curiosity stream. Thanks 😉

[@murtelizer]

I had the same issue with nebula, it takes forever to load, long buffer times and not really user friendly. Its a shame they dont put effort to make the site work well. And dont get me started on the mobile app (which didn't even boot 99% of the time). I greatly like and support their idea of building their own site but the exclusive content being locked behind such a bad working site is a real bummer for me :/

[@officer_baitlyn]

@@murtelizer the price is prob a bit too low for it to be perfect

[@murtelizer]

@@officer_baitlyn just basic loading of the video when i have gbps internet so that a 1080p video doesnt buffer is not much to ask in my opinion

[@kaitlyn__L]

@@murtelizer yeah it’s all about how much server space they’re willing to bid for, not about the actual connections at either end really. Hosts gotta serve to users, and I doubt if there’s CDNs involved, hence longer initial load time even before buffering begins.

[@murtelizer]

@@kaitlyn__L still the buffering and long loading is a deal breaker for me personally

Absolutely fascinating science. Very well done mini-documentary. You literally answered every question that entered into my mind while watching this amazing video. Bravo!!!

Your videos never fail to fascinate me, i love this channel so much 😍 thank you for adding value to the life of most of your viewers!!

Why is Spider-Man in the background at 9:00

[@Rizzbulla]

I want to see a plane made out of mostly webs, besides the frame. Or a drag car.

Thanks for being part of the movement that makes KZbin great and spreads wishdom and knowledge around the world, so that everybody can learn, you will inspire kids to follow in your footsteps and become scientists in the field. Thanks for being a role model like that.

The answer to "why" is very simple. It's awesome. It always bugs me that nobody ever gives olde time people credit for maybe just wanting to do something because they had the time, and the means, and it would be really cool.

[@Roxas671]

It might be stronger than steel but the real question is, is it heavier than feathers?

[@Skjorrious]

I even read it with the voice

Is 1kg of spider silk heavier than 1kg of feathers

Now imagine the military investing in genetically modified large spiders that can create an even more stronger strain of silk. I wouldn’t be surprised if such thing is already in the works or at least attempted.

[@binay413963]

Shhhh

[@rextech-q]

Nice video 👍. Biology is epic. Just imagine having some genetically engineered spiders at home to sew you new cloths or patch any holes in your wardrobe. Maybe less popular, using them as mobile hole patching units ^^". Even more advanced, we could give them "wound healing/disenfaction"-glands.

[@rextech-q]

And if a (possibly infectious) mosquito tries to bite you, they will learn the hard way about your spider friendos.

[@minhducnguyen9276]

Spiders have all the traits that's undesireable for large scale farming unfortunately. They are strictly carnivorous so it's expensive to feed them in large scale, they are solitary so you can't farm them in dense population and you have no control over the secretion of silk unlike cows, chicken or silkworm. That's why our spider silk are always made from other farm animals grafted with spider silk making genes.

[@glacousxx]

Good to know that im closer to spiderman than my predecessors.

[@simonvincent9682]

Wow! What a fantastic channel this is. Thank you for all you do

[@sapelesteve]

Excellent and informative video RS! Spiders are indeed wonders of Nature & let's not forget about their production of various venoms as well. Looking forward to your next video! 👍👍😉😉

Growing up navajo were told that when you find a empty web but perfectly spun and weaved, you should rub the entire web in your hands and ask that your work be as good as this spiders web.

Today I learnt how it was possible for Spiderman to stop a train just with his webs.

[@Bassetowner123]

Its absolutely amazing to me that our technology has reached such an advanced state and we still cant replicate many compounds made in nature. You'd think that replicating spider silk would be easy with our technology but nature is king.

[@center1581]

Really cool video. It reminds me of this one technology I believe the U.S. Army was developing in which they cross bred a silk worm with some other form of worm and they were testing ballistic armor using that material.

[@johnnysam3604]

I love the content you are putting out keep the great work up!!

[@SizzleCorndog]

Okay so second comment 2 years later which is kinda cringe, but I’m in grad school rn and we’re studying the polymer structures of spider silk. One of the biggest challenges with this is the extrusion process like you said, but the problem with replicating it isn’t just that it needs to have a certain molecular weight (Mw) but real spider silk is a composite in and of itself. Essentially as the protein structures travel down the initial silk glands they hit a change in pH, get coated in another layer with different proteins, and then get extruded as two strands in parallel. Another thing, and probably the most important, to consider is that a lot of these proteins go through post translation modification which aids them in the extrusion process and this is probably the reason why we see spider silk in ball park of 350kDa and I’d wager is the reason why people haven’t jumped on the bacterial silk since as Mw increases you start getting more viscous and less flexible.

[@kaitlyn__L]

This was an excellent video. Lots of wonderful diagrams, animations, and stock footage. I’ve seen some spin it much like nylon, but I guess that ends up not being strong enough? Still, it would be interesting if we end up getting orbital tethers built from artificial spider silk rather than steel or carbon (nanotube) cables! Besides many other uses of course. Like you say in the end, nylon might well end-up totally outmoded in the future, especially if the growing process can be scaled enough to be cheaper than the sourcing of raw petrochemical ingredients. People might have very strong spider silk tights/stockings and be confused why they used to snag/tear/run so much in the past! Plus, here’s another comment about Thought Emporium’s series about actually genetically modifying yeast to produce spider silk for those who want more nitty-gritty info on the delicacy of the process! :D It’s many hours long though in total, while this is a brilliant concise overview.

[@MylkT1023]

Are we going to ignore the fact that Spider-Man just walked across the background at 9:34???

I grew up in the Philippines 🇵🇭 and Golden Spider are endemic its everywhere in the urban areas where you can find them in hordes at the electrical post and lamp post in the mango trees and in the vast forest. They freak me out cuz they're big like bigger than cockroach but beautiful animals.
