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

    https://onlinelibrary.wiley.com/doi/full/10.1002/ece3.10332

    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.

      Garden snails around seattle will absolutely bite you (teeny tiny bite) and draw blood if you let them crawl around on your skin.
    • Sharlin 6 hours ago
      Analogous to the keratinous denticles in a cat tongue, just much smaller in scale.
    • deepsun 6 hours ago
      "try"? If it's harder than your skin it means it did, not tried.
      • xboxnolifes 1 hour ago
        Just because you succeeded doesn't mean you didn't try.
      • hedgehog 5 hours ago
        It may have gotten a nibble but empirically I still have a finger :)
        • dylan604 4 hours ago
          Doesn't mean you were not bitten though.
          • recursive 39 minutes ago
            If it wasn't accidental, that bite represents an attempt to bite.
      • ozyschmozy 2 hours ago
        A steel door is certainly harder than my skin and also certainly can't be used to "bite" me or puncture my skin (save for crushing it given enough force)
      • jayd16 3 hours ago
        Just because it's harder doesn't mean it necessarily has the strength to tear off skin.

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

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

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

    • bjt 42 minutes ago
      I also thought that was weird. Then I learned it gets better. If you click through to the BBC article that was apparently their main source, the quote is this:

      > Alternatively, as Prof Barber explained, it can be compared to a single string of spaghetti holding up 3,000 half-kilogram bags of sugar.

      So the professor used an item that was familiar to his English audience (1500 kg=3307 lbs), then the Smithsonian writer tried to be helpful in converting the units, but switched to an item far less familiar to an American. I don't think I've ever bought a 1lb bag of sugar here, while a 500g bag is a little small but normal in the UK.

      But everyone knows, by experience, what 3300 individual roughly one pound bags of sugar weighs and what sort of force is needed to hold it up. Mid sized car is ambiguous, and nobody saw anybody hold that up (seeing hulk doesn't count)
      • Loughla 45 minutes ago
        But what is it in football fields?

        That's the usual measurement of size in the States and it's absolutely unbelievably ridiculous.

      • jaapz 1 hour ago
        You think people are better at estimating what 3300 bags of sugar look like - as opposed to estimating the size of a car?

        How often has anyone ever seen 3300 bags of sugar together in their lives, do you think?

      • saberience 2 hours ago
        Do they? I don't recall ever seeing a bag of sugar in my life. I'm not a baker though so maybe that explains it.

        A car is more easier to picture for me.

          You must be from the US.
          • dmoy 1 hour ago
            I am from the US and buy bags of sugar.

            What else does sugar come in? If not bags? I don't think I've ever bought sugar in something other than a bag.

    • kbelder 43 minutes ago
      I'm guessing this was initially '1.5 metric tons', and through a number of helpful and friendly conversions, ended up at 3,300 sugar bags.
    • sph 2 hours ago

      > 3,300 one-pound bags of sugar

      Woah that must weigh almost 3,301 pounds!

      • sph 2 hours ago
        No, it’s 3,300 £1 bags of sugar, with undefined weight
    • flippyhead 3 hours ago
      Must be a british thing?
      • natebc 2 hours ago
        well that's just £3300 then, yeah?
        • tucnak 2 hours ago
          Half that, 3300 pounds of sugar is roughly 1800 quid (retail) and wholesale is probably half of that.
          • natebc 2 hours ago
            Well that's what ... 300 or so pints?
            • dmoy 1 hour ago
              Wait beer in the UK is 11 quid per pint??? I know UK pints are bigger, but that seems really pricey
              • natebc 20 minutes ago
                I estimated about 6 quid. We left £3300 behind because 3300 1-lb bags of sugar only costs £1800.

                ;) I like these easy breezy Late Friday threads!

    • echelon 3 hours ago
      I can't wait until our LLM agents spot these and substitute in our own favorite, personally intuitive format conversions appropriate for the scale.

      I'd like this to be expressed in units of pallet(s) of standard cinder blocks.

    If you ever watch these guys in an aquarium, you notice they're basically constantly chewing on things. I've wondered many times how they keep such tiny teeth in good condition if they never given them a rest, but, here's why. Nature creates such cool creatures
  • RajT88 6 hours ago
    > 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".

    • loloquwowndueo 6 hours ago
      Sorry I only understand football field based units of measurement
      • fnordpiglet 6 hours ago
        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.
          • djtriptych 5 hours ago
            ok but what color is the yak hair?
            • thenewwazoo 4 hours ago
              Same color as the bike shed, obviously
            • eth0up 3 hours ago
              Not from Unitzikstan I see

              White, of course; that way the statisticians can dye them any color they want. But for ultra high precision I do recommend the Boeing system. But be sure to use the older models, before private equity firms replaced all the metal parts with zipties. If you can't find a quality Boeing (plausible), consider 1.1 Blue Whales (tricky).

              fnordpiglet was being deliberately humble with the decimals. It's accurate down to the semi firkin. Not to be confused with a quarter Tod.

              Ignore the redundant bike shed comment, as that fits precisely 3,300 one-pound bags of sugar. Anyone with a bike should know that.

        Obviously it weighs 10,300 baseballs, which are 26 football fields long.
      • isatty 3 hours ago
        A football field is by far a better measurement than 3300 one pound bags of sugar.
        • sph 2 hours ago
          It is not if all you know are football fields and not American football fields.

          I still don’t know how they even compare.

          • bch 2 hours ago
            That's why we use the %fill of an Olympic Sized Pool - doesn't matter from what continent the field comes, they fill the pool equally.

          OP is talking about a football field, not a soccer field. It’s a common joke in America that things have to be measured in football terms.

          In the “for what it’s worth” department, Brits called it soccer too. I have no idea why they swapped to football recently.

        Those are crushing power, and while they use bad terms for it, they are referring to tensile strength specifically, which is totally different. I don’t know why the hell they chose a spaghetti strand though.

        Yeah, I am quite certain I have an easier time visualizing a one-pound bag of sugar—which I have seen at the grocery-store/kitchen/pantry—versus a single-pound bag of concrete.

    They say they’re taking about tensile strength at the footnote. But teeth would be more likely to be compressively strong. They don’t get pulled on much.
