😂😂 love the random spiderman at 9:35 but also love the in depth detail as I've always wondered what exactly it meant "spider silk is stronger than steel"
I was about to comment the same thing, where does this footage come from 🤣
Spider-Man might be upgrading his web shooters
@@raymoncada bet 😂
I actually did a double take and rewound the video to check that I saw what I thought I saw. :D
nah swear down I was about to say the same
9:36 The casual Spiderman completely caught me off guard 😅
Nice video!
Fr bro same
@@phillipmathura8763 Glad I'm not the only one who saw spidey, nice touch.
my favorit part of the video
Yeah, was not expecting that
I was like: wtf? A spidey in a lab?? Did I see well? Then it clicked that is a video about spiders and smiled noticing what she did there
I love the Spider-Man walkthrough absolutely brilliant
Haha, yeah. I think most people missed the scene
I came here to say this!
9:35
I thought I was trippin
I was high when I saw it but I’m glad others caught it
9:32 Spider-Man just casually walking around the lab.
One of my favourite RS videos to date. Material science crossed with biology? Kinda wish I went into spider silk research
Haha
You know, I'm something of a scientist myself.
@@TheFos88 producing sticky goo substance on a regular basis? ;)
@Real Engineering It is not too late!
You want to make iron spider suit, dont you
Spider man walking through the background at 9:34 was a nice touch
i did a double take when i saw that lol
@@Disobeyedtoast Same
I didn't even notice that lol 😂
Spiderman caught on camera stealing high tech synthetic spider venom to inject himself.
@@magno5157 he’s a junkie, lol.
Spiders are such beautiful and magnificent creatures. I wish more people could appreciate them and all their wonder.
A spider typed this.
Sounds like what a spider would say..
Same
Spider sponsored comment
Hear hear! Spiders are amazing, but such a shame that a lot of humans allow their primitive lizard brain to inhibit them from fully appreciating spiders and their beauty.
in a rural area, i saw a stick that was hanging from a thread, it wasnt there the day before and it just looked weird, like one of those suckers that are on the roof in half life, i grabbed the stick and threw it away and after that i looked up to see what it was connected to, turns out it was a counter weight for a web that was between 2 trees, without it, the web started moving due to the wind and was ultimately destroyed, dunno what happened to the spider and i kinda felt bad for destroying something so ingenious
evil...
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.
Greek myths are stupid
Nice myth
good delusion
very cool
Not a Greek myth btw
This myth was made by Ovid (a Roman poet)
Spiderman just casually walking in the background of the lab shot is fucking amazing 😂
Some may even say, Spectacular!
oh, that's just the lab's PR spokesman
Seems pretty ultimate to me
I wonder what guitar strings from spider silk would sound like. I suspect finger oils are far more destructive to it though, so wouldn't expect them to last nearly as long.
Hmmm yeah I wonder that too. They’re very durable for every reason they said, but how do they do with external factors like rain, wind, but also animals and humans to touch it etc etc. In that regard it probablt isn’t nearly as effective but steel, but they didn’t really say anything anout that which makes me wonder if they did/are gonna do research on it
Someone made a spider guitar string. Search it on RUclips. Interesting video.
Another amazing episode. All of your videos that I’ve seen so far have been amazingly interesting and well done; and, I just want to say thank you for putting out the effort to create all the super interesting and enlightening content! 👍
What I find fascinating about many spiders is that they can create a very beautiful and perfect looking web while being nearly blind or completely blind.
Then let us fascinate you further.
Look up _Spider web memory_ unless you already know what I'm talking about.
There is even a Deep Look video on YT
spiders aren't blind. where you hear about it?
@@suchyjaszczur many orb weavers are *almost* blind. The same goes for tarantulas.
Many others, like wolf spiders, jumping spiders and ogre spiders, have very good eye sight.
If you watch a spider build its web, you'll see it uses its limbs to carefully feel and distance the web joints together in a clockwork fashion.( edit I said it is limbs )
@@andycruzatx3387 that was part of what creeped me out as a kid, so many limbs feeling around constantly, but in slow motion it just looks like how a person working looks (or would, like if we had extra robotic arms or something) on something a bit complicated. Like craftspeople who are all “if only I had a third/fourth hand”, instead of picking things up and putting them down as much they’d just use extra hands and do it quicker. And a spider building a web looks very much like that to me now. A carpenter or electrical engineer etc, doing something intricate.
Makes me wonder how Peter Parker was able to concoct his complex chemical compounded spider fluid.
Peter is a genius who lives in an universe where the average genius scientist invents time travel over night.
They explain it in one version as he inherited the knowledge from the spider who bit him giving him knowledge of the correct proteins to mix
Obadiah Stane: Peter Parker was able to make this at school! With a handful of chemicals!
Ask him, he appears at 9:34
plot twist, spiderman is also a scientist
My university actually had some spider silk producing goats! A few years ago, they brought them on campus and I was able to see them. It was really fun.
There is one more properties of Spider silk You "forget" to mention - it changes it's mechanical porperties very much when heated and also it burns (no fire resistance)
Build a winter bridge? 😛
Wait until you find out steel melts when heated
I learned alot from this. I had no idea there was multiple types of spider silk for different parts of their web. Another great video
You should check out The Quran , for real . Forget about ISIS , long beard and child marriage! Take heed for your self and research everything. The Quran is an amazing book , giving us hints about whole creation of Heavens and The Earth . God is greater than religion , God is Fantastic !
Peace be up on you and up on your family .
What does the quran have anything to do with the few different silks that they use for the web lol
@@finallyfamous9628 Why would the Prophet talk about the house of spin ? In the 7th century , middel of desert ? We see now , in this time what it's so especial about it , but he didn't have means to study about spiders and he was not a scientist . If you can understand what I mean , .. Peace be up on you as well
@@adrianabonitaaziz Sanatan(Hinduism) is the only way, all these other are just imaginary concepts.
@@adrianabonitaaziz ew why would i study a book of a dictator telling me how to live my life when i can study science and make a difference for myself and the world?
The fact that it is made from a liquid makes me hope we can print or even 3d print with it. I have no idea how well it would adhere to the other layers in a 3d print, but even just making 2d patters of the material to reinforce other thin materials would be awesome.
I can’t wait, the future of 3D printing foods and products in general is going to be amazing 🤩
1- Tape a spider to a 3d printer
2- Make a 3d printed squeezer to squeeze the silk
3- squeeze the silk
4- ????
5- profit
You need to spin it to yield viable thread which 3D printer can't do
@@abdulazis400 obviously this 3d printer that utilizes liquid spider silk would be built to actually work. No one suggested that it would just squirt out a regular fdm 3d printer.
It's probably best as a fiber reinforcement inside a matrix like carbon fiber or fiberglass reinforced plastics
That was the best segue into the ad promotion I've ever seen. Completely flawless and non-jarring. The video itself was also amazing! Thank you
It never ceases to amaze me, the unique ability of humans to pick the best traits from nature, and construct them from scratch.
FYI - copying something is not the same as constructing from scratch.
Nothing in nature has been 100% replicated by human technology - it has only been approximated due to practical limitations.
Design in nature is of a higher order than human imagination. Let that sink in.
Yes Nature has the facts, so does observing your body, you was born with the math.
@@Chris_Sheridan Facts, and that is documented.
@@Chris_Sheridan Human imagination is designed by Nature, well.. We havent stopped evolving though.
@@bezovrinho .. your opinion or a fact?
You can't even substantiate your opinion - 'designed by Nature'? .. so what designed Nature'?
Nature is something that is observable - it does not describe the cause. I can observe a bicycle and all its intricate mechanisms - however, that alone does not give the information as to how the bike came to be assembled and where the original parts came from and the engineers who designed and built it.
The term Nature does not describe a process - it merely relates to what is observed. Your statement is completely bland showing your ignorance.
Where is your evidence that humans are 'evolving'? .. from what into what? Humans have remained human for thousands of years.
You know nothing - your post says nothing - your ignorance is pathetic.
I remember watching a video where Myth Busters Adam Savage did a test with some kids and proved the concept. They did two test with gallons of water dripping into buckets held up by either a cord of steel and a cord of spider silk. 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.
@DILLIGAF * mass usually is a factor since to have them as equal as possible since one is larger then the other.
How do you get that much spider silk 🤨
not only that, but it's been said that various companies are trying to create a type of bulletproof vests that are made out of spider silk (or creating plates using the stuff) that's supposed to be stronger than both steel and ceramic armored plates, or something to that effect
@@DrQuagmire1 that'd be cool because it'd probably be reusable too instead of throw away plates!
they used an inaccurate and unnatural manifestation of a spider web therefore their 'science' isn't accurate
I work in the analytical department at Lubrizol and we just had an interview candidate come in and present their research on the material properties of spider silk. A lot of what they said was in this video. I dont remember where they were studying/ when they put out their research, but hearing that ppl are close to being able to mass produce it has me so hopeful for the future when we can finally get rid of plastics fibers because they are so insanely difficult to break down even from a chemical perspective. Genuinely never more excited for science after watching this video.
I’m surprised your company allows you to publicly discuss company business and candidate
Interviews. I’d be fired if I did that.
@@RangeGleasry 1. They don’t know. 2. This wasn’t company technology that was being presented this was someone’s doctorate research, we were just doing a department interview which as I understand it is pretty normal for advanced positions across the industry.
university of california riverside has a dedicated massive spider lab where they do a lot of this research amongst other things spider related
Im currently learning about cell free protein synthesis which is a relatively new technique and this would be the perfect application for it! Since the synthesis happens outside of a host cell there’s not limitation to the size of the protein.
Policeman to thief "i am wearing Bulletproof vest".
Thief: "I am wearing Spider silk Vest".
Policeman: "Understandable, have a nice day".
9:35 I love how there just walks a spiderman in the background.
9:34 ah yes spiderman
A delightful documentary. Thank you for sharing!
If we could know the chemical concoction that goes on in the spiders glands to make the silk, we’d be able to make our own silk material
Very good content - thanks! But there's more to it than the protein chemistry. The golden orb thread has layers of proteins that mechanically slip past each other in a controlled manner to relieve strain. That would be a real challenge to reproduce even if the proteins were made. We remain in awe at the incredible properties of the real thread.
We remain in awe at the incredible nature of all things natural.
@@skyline.730 true. Nature is genuinely the most beautiful and fascinating
People claim an all-powerful creator put Homo Sapiens here to rule the Earth and the entire Universe...
Yet we are still taking notes from spiders, termites and dragonflies while we destroy the only world we have...
But god and Jubus and all that nonsense about going somewhere pretty after you die allows you to pump out all of those ignorant babies, and push for the end of the world...
Cults should be banned, no matter how many followers they have.

Didn’t we have an entire Wild Kratts episode on why it’s not ok to force spiders to make clothes?
back in high school i did a presentation in AP science about scientists trying to use goats to mass produce spider silk. they basically genetically modified a couple goats because their milk had capabilities of reproducing spider silk like material.
9:34 we just gonna ignore spiderman in the background?
9:33 did anyone else notice spider-man just casually strolling by in the background?
The first hiker up in the morning while backpacking is called a silk blazer, because of all the spider webs to walk through
Thanks for being part of the movement that makes RUclips 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.
9:35 spiderman in the background
I remember when we began trying to develop spider silk from goats' milk. It was incredibly promising at the time.
@Dah Pluggg no one is
Now I'm wondering what happened to those guys.

Remember when that was a conspiracy theory and everyone called a certain someone crazy and turned out to be true?... Spider goats are easily googlable
@@se6586 no
When I first heard about the goats a few years ago, I imagined them to be extruding spider web from their udders 😂
A gem of a channel. Thank you for this content.
9:35 random Spider Man
So glad RUclips recommended me this channel. Love this video already subscribed and now binge watching your other videos. The video “ the secrets language of trees” is amazing.
I remember this one guy in the 90s spent a whole lot of time making an body armor out of silk webbing. It took him years to gather up the material, but he made a suit that had crazy durability.
Media brainwashed me into being scared from spiders, I'm re learning to love them.
Awesome job. Great Narrator!! One of my top 5 most fascinating things is spider silk. Thank you for the in depth research.
I gotta get that spidersilk vest and those adidas 😂. Fly as hell
Love how you enlighten us through intricate method used by researchers in developing silk protein ...and also prevented me from going into deep reading!

This was fascinating! I adore spiders and this was so interesting to see.
@@Die-Angst It is? I´m merely writing in past tense, as I commented after watching the video.
I love spiders with all my soul, and I am so happy to see how close we are to replicating it.
😯😯
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.
That was an awesome video, your great!
this video is so well-made. the visuals were awesome. so awesome that in the beginning I was getting the heebie-jeebies with the spider clips but then grew to appreciate more. seeing what good/greatness humanity can do with things like this responsibly is one of the pinnacles of science
this video is great !! alot of professional work is put in these videos and the quality is great, keep up the good work you got this !!
Very nice segue. Thanks for the video.
9:34 xD that spiderman in the background, too good
There's a specific fungus on Fraser Island, Australia that I think would be useful for producing spider silk. I think the same fungus, along with CRISPR could also be used to grow super efficient solar cells :)
Woahh interesting, where can I learn more about this?
Do you have sources?
@@AlxM96 Well, as RUclips wont let us share links anymore, no, not really. I came across the fungus by chance in a 4x4 video from Australia. There are many videos on RUclips of crystals being used as batteries. Did you know that rubies absorb non-red light and re-emit it as red light! The more I learn, the more this seems possible but I'm just a poor person so no one cares 😢
Is there a particular aspect you'd like more detail on?
@@honestlyimnotsure9378 Sadly, this is not really being researched and I lack the funding to do much more than scour the internet for relevant scientific information lol
@@AlxM96 The fungus in question, by the way, I don't know it's technical name but Fraser Island is made up of volcanic rock and yet it's a lush tropical paradise because of this fungus! I believe it to be the same or similar to the fungus that is responsible for plant life being able to start on land. It converts the rocks and such into essentially dirt :D
I believe with a bit of modification and the addition of glass sea sponge DNA, we could get it to "print", or, rather, grow all sorts of useful crystalline structures! Maybe even carbon nanotubes!
I've seen a guy on RUclips make spider silk from bacteria, I have a feeling spider silk clothing will be far more prevalent soon. If one guy can do it, some corporation out there is attempting to mass produce.
Eh depends if it's easier than traditional methods or profitable. Just because they can won't mean they will.
Have you watched the whole video?
too expensive
@@ViperRUSTzz it’s made of spider silk, not everyone is poor, I can see quite a few rich people buying it.
Humans: * creates nylons *
Nature to spiders: look what they need to mimic a fraction of our power
Spiders: look what they need to mimic a fraction of our power!
Hey, just wanna say. I love your videos and that I learn a lot from them. I’m 30, I went to school for graphic design and you’ve “spun” these videos in a manner where I understand and can follow comfortably. Keep up the amazing work!
I am always curious when I see spiderwebs. They are an amazing hunting tool. I like having one or two on my balcony. When I go out for a smoke or coffee outside I always want to see a spider mid construction or when a bug flies into it. My favorite type of predator.
👍
a co-worker and i found a spider in the corner of the shop, for a while tossed any flies we swatted into her net to help her out.
@@windhelmguard5295 we also had a pet spider at the shop a couple years back near the old tires. Was pretty cool to see her grow throughout the year.
@@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.
Spiders are good in order to keep cockroaches and other insects at bay specially flies. I used to have around 10 spiders nest in one of my garages and never bothered them. Unfortunately where I am at it gets cold temperatures and most spiders and insects don’t like the cold I guess.
Your voice is so calming an captivating 😍
Really great content!
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)."
The most german of comments and I appreciate it!=)
Except you are wrong. The fact that you cant even provide a source further proves my point.
@@Teo-uw7mh I'm not and a provided a source. Just because you are not willing to look into the works of A.A. Griffith doesn't mean it's wrong. You find the primary source in "The phenomena of rupture and flow in solids" by the royal society in 1921 by A.A. Griffith.
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.
This has to be the most exciting concept you've covered yet for my money... The intersection of biotech, materials science and mass manufacturing for such a variety of potential applications which could also help replace organic/fossil fuel based plastics or fibres is a pretty cool perfect storm of scienceing... 😎👌😍🕸️🕷️
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
As much as I dislike spiders in my home, this definitely makes me appreciate just how intricate their bodies are. I had no idea there were so many different types of silk for so many different tasks. Imagine having the knowledge to build a masterful web imbedded in you from millions of years of trial and error made by your ancestors. I apologize if this was confusing to read I'm not the best typer
I love how much detail these videos have, good job!!
9:33 Spider-Man
Fascinating. Thanks.
I’m surprised that all the attempts to make spider silk have involved genetic engineering, rather than a mechanical system. In other words, couldn’t we create a mechanical spider abdomen that mirrors the natural chemical process to “manufacture” spider silk? 🤔
There was a big storm passing by here in Belgium Yesterday. Outside my bedroom window was a spider living in the top corner. I checked in on it now and then, the poor thing was struggling to hold on to it's web. Later when i checked again, the spider was gone, but the web is intact. Unbelievable how strong it is.
It's amazing how scientists used so many variations to reach at an answer and are still continuing to improve. It's beautiful.
I am studying now bio-inspired materials, this channel is the best thing that I have ever seen to connect material science with biology
How would you harvest spider silk? Ive seen videos about harvesting silk worm silk. What would the setup be? How would you feed them? How would you keep them contained, especially the babies?
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!!
Really love the details.
And the presentation is awesome.
Expecting more exciting scientific content.
My regards,
To the team, for putting such extrinsic effort.
we need this
I'm glad at least no scientist thought of making giant spiders 😰
amazing video. its pretty much a "reverse clickbait" as not only you explained the process of spider silk but how we are working to recreate it, and the pace we are at right now. the curiosity plug in was also pretty relevant too, being similar topic
Absolutely fascinating science. Very well done mini-documentary. You literally answered every question that entered into my mind while watching this amazing video. Bravo!!!
Finally I know what to do when I get a time machine: go step on the protospider.
Spiderman casually walking in the background past the two scientists was the little gem inside this video lol
I watch and read a lot about spiders and this video is quite high on quantity and quality of information provided. Genuinely impressed.
...And super extra bonus points (as well as a like) for not using creepy violin music (or the like) every time a spider is on screen. 👍
This is one of those videos where you get wowed in every few minutes of watching. Thanks a lot real science for making such amazing video. And the narrator was phenomenal with her voice!
.. the narrator attributed spiders and spider silk to 'millions of years of evolution' - totally false.
Great video! Just a comment, I believe that the dragline silk its not a composite, the amorphous and cristaline regions ara common in polymers. And since proteins are actually polymers, spider silk its a super strong biopolymer, and I think that's kinda crazy.
great info, thanks
Why is Spider-Man in the background at 9:00
9:23 amazing!! spiderman whhhhoahhh!!!
love ur stuff
I want to see a plane made out of mostly webs, besides the frame. Or a drag car.
Wow! What a fantastic channel this is. Thank you for all you do
Now I can finally ask: what do plants, goats, silkworms, and bacteria have in common? They've produced immitation spider silk. :)
What's the sound track playing at the start in the background of the speaking audio of the video called?
There you go. Learning from nature rather then using others to test things too painful or lethal for our species. Good job on this one
I love the content you are putting out keep the great work up!!
9:34 background
Thought we wouldn't notice, but we did :D
You know, I read about EVERYTHING in this video like 20 years ago… and all they’ve produced since then was that one shawl, that we don’t seem to be doing any testing with. it’s just sitting there.
Yeah, I’m not holding my breath on spider silk armor being available at the local sporting goods store anytime soon ….
Thank you very much for interesting story about spiders.
