    😂😂 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 stee
  • @CruzMonrreal
    9:36 The casual Spiderman completely caught me off guard 😅 Nice video
  • @gsmith7309
    I love the Spider-Man walkthrough absolutely brilliant
  • Spiders are such beautiful and magnificent creatures. I wish more people could appreciate them and all their wonder.
  • @RealEngineering
    One of my favourite RS videos to date. Material science crossed with biology? Kinda wish I went into spider silk research
  • 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
  • Spiderman just casually walking in the background of the lab shot is fucking amazing 😂

    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.

    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.
  • @mxcollin95
    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! 👍
  • @skylaninaction
    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
  • Makes me wonder how Peter Parker was able to concoct his complex chemical compounded spider fluid.
  • @alf8718
    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)
  • @lukash.8788
    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.
  • @huldu
    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.
  • @shadowwriter329
    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.
  • Policeman to thief "i am wearing Bulletproof vest". Thief: "I am wearing Spider silk Vest". Policeman: "Understandable, have a nice day".
  • 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.
