      imagine growing tools out of this stuff instead of forging or casting, that'd be neat.

    > 3,300 one-pound bags of sugar

    Ah, but how many one pound bags of concrete could it hold??

    Why bags of anything? This is a poor way of communicating weight. Just say "a modern passenger car".

      Well if they’re quoting that as the failure point then by definition it cannot.

      The main question is how many American football fields is that

      Sorry I only understand football field based units of measurement

        It’s a real condition. For me it’s jet liners of various makes. I had to rewrite the quote as “0.005 Boeing 777’s” to be able to comprehend just how strong those snails teeth are.

          Sorry, but that's what 14 (standard) pickup trucks of yak hair was invented for.
          • djtriptych44 minutes ago
            ok but what color is the yak hair?
      • Rooster6113 minutes ago
        Wait, I can do that? Here I've been using Smoots this whole time (with great difficulty might I add).
      • bell-cotan hour ago
        Understandable, with how many there are to pick from, and the wiggle room in the longest ones -

      whenever i see things like this i think its a tongue-in-cheek joke

      more importantly: how many kilos of feathers versus how many kilos of steel can it hold?

      3.3 kilopounds? That's a lot

      How about

      > 10x stronger than the jaw of a dog

      > 20x stronger than a human jaw

      > as strong as the jaws of a great white shark

      ?

        But how many times can it bite the area of Rhode island?

      because as a reader, bags of sugar are more engaging to me than bags of concrete.

      > Thats’s comparable to a single strand of spaghetti holding up about 3,300 one-pound bags of sugar

      Is that cooked or raw spaghetti?

      • mannykannot37 minutes ago
        Why complicate matters with pasta at all when spider silk is, at least metaphorically and rhetorically, at hand?

        As hinted at by its 2017 postscript, this article is a mess of incommensurable comparisons.

      • giwookan hour ago
        Is it De Cecco though or some inferior brand like Barilla?
    • riffican hour ago
      anything but the metric system.
      • BLKNSLVR22 minutes ago
        1,497 one-kilogram bags of sugar.

        Much better!

      I noticed that too. I feel like this might be a new way of laundering AI written text, just provide the quote verbatim as if the they believe it was actually written by the author.

    I wanted to see some pictures, this paper has good ones:

    If you put your finger in front of a garden slug it may try to eat it, it's a very odd sand-paper sensation but I never knew why.

    • horacemoracean hour ago
      Garden snails around seattle will absolutely bite you (teeny tiny bite) and draw blood if you let them crawl around on your skin.
    • Sharlin2 hours ago
      Analogous to the keratinous denticles in a cat tongue, just much smaller in scale.
    • deepsun2 hours ago
      "try"? If it's harder than your skin it means it did, not tried.
      • hedgehog42 minutes ago
        It may have gotten a nibble but empirically I still have a finger :)

      Well that was more disturbing than I thought it would be.

    What an odd example. A mid-sized car would have been much clearer.

    [2015], with a nice correction from 2017 about the differences between compressive and tensile strength.

      And hardness. Diamond is hard but exactly because of that you can shatter a diamond with any hammer.
    • codesnik2 hours ago
      now, let's combine both.

        Do you prefer a web-weaving snail or an extra-bitey spider? I'm leaning spider.
        • ssl-321 minutes ago
          I want an orangutan that slowly spins webs of extruded snail teeth.

    Snails had a good run being ignored by everyone but the French and now we're smearing their slime on our faces and trying to turn their teeth into armor.
    • blipvert2 hours ago
      Snails? These are MARINE snails, soldier! Oorah!
      • zarflaxan hour ago
        Makes you wonder how and why they evolved such strong teeth since crayons are pretty soft (and not even naturally-occurring).
      • imzadian hour ago
        Oops
  • cwmoore2 hours ago
    Which is the less intelligent? Strong works when dumb.

    I know people like to talk about “how smart” the butterfly or whatever is for “adapting itself” to whatever environment, and it is cute, but there is a practical engineering choice between delicate design and brute force.
