    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.

      Garden snails around seattle will absolutely bite you (teeny tiny bite) and draw blood if you let them crawl around on your skin.

      Analogous to the keratinous denticles in a cat tongue, just much smaller in scale.

      "try"? If it's harder than your skin it means it did, not tried.

        Just because you succeeded doesn't mean you didn't try.

          Doesn't mean you were not bitten though.
          • recursive 15 hours ago
            If it wasn't accidental, that bite represents an attempt to bite.
          • Brian_K_White 2 hours ago
            It does mean they were not eaten.

        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 18 hours ago
        Just because it's harder doesn't mean it necessarily has the strength to tear off skin.

    > 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 15 hours 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)
      • jaapz 16 hours 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?

      • Loughla 15 hours ago
        But what is it in football fields?

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

      • saberience 17 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.

            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.

              Not Mary Berry, then. Or anyone else who ever baked a cake. Or cooked, really.

              I hate sugar in food, but some recipes use sugar to balance acidity (e.g. tomato ketchup).

    • necovek 11 hours ago
      While I am totally with you on the bags of sugar, I am also unsure of the significance of a single thread of spaghetti!

      Is that by weight? By volume? Are we comparing uncooked (brittle) or cooked (flexible)?

      Even so, spaghetti strand is not known for strength or tension resistance even when considering the weight/size/volume.

      I can't at all understand what this comparison is meant to visualize for me, so it is obviously failing.

      • dyauspitr 1 hour ago
        You’re meant to visualize a strand as thin as spaghetti holding up an entire car. It’s an impressive visual. The properties of spaghetti (aside from its thickness) has nothing to do with anything here.
      • yallpendantools 8 hours ago
        > Is that by weight? By volume?

        It's holding up 3300 pounds. Pounds is a unit of weight.

        > Even so, spaghetti strand is not known for strength or tension resistance even when considering the weight/size/volume.

        That's...kinda the point? We have something we don't give two thoughts about (slug tooth) comparable in scale to something not known for strength or tension resistance (spaghetti) holding up to something ginormous as if it's magic. Clearly, we should study slug teeth more!

        Imagine if a strand of spaghetti can hold 3300 pounds. It's not possible with spaghetti but with slug teeth, it is! Now imagine the possibilities!

        • B1FF_PSUVM 3 hours ago
          > imagine the possibilities!

          Does a 35,786 km "strand of [slug-tooth] spaghetti" hold its own weight?

        It's not a question of where the car is from! It's a simple question of weight ratios! A one gram strand of noodle could not carry a 1 tonne car.

      • JsonDemWitOster 8 hours ago
        That depends. Is the spaghetti made of pure Italian semolina or some bastardized all-purpose flour-based dough? Also, the cut thickness matters as well as how much you salted the water to boil it AND for how long you boiled it. How far is it in the raw-al dente scale?
      • necovek 11 hours ago

    • kbelder 15 hours 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.

      • JsonDemWitOster 8 hours ago
        Non, du verstehst es falsch, mon amigo. According to EU standards (of which the Brits are no longer a part of) sugar bags (empty) should weigh exactly a pound each to withstand all and any shipping conditions.
      • natebc 18 hours ago
        well that's just £3300 then, yeah?
        • tucnak 17 hours ago
          Half that, 3300 pounds of sugar is roughly 1800 quid (retail) and wholesale is probably half of that.
          • natebc 17 hours ago
            Well that's what ... 300 or so pints?
            • dmoy 16 hours ago
              Wait beer in the UK is 11 quid per pint??? I know UK pints are bigger, but that seems really pricey
              • natebc 15 hours 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!

      Sorry I only understand football field based units of measurement
      • nrdvana 23 minutes ago
        It turns out an astroturf American football field probably weighs 1700 tons, mostly from the 6 inches of stone base under the astroturf. So 3300lbs is .00097 football fields.

              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.

            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.
            • necovek 11 hours ago
              Aren't there significant differences in allowed depth (from minimum of 2m to maximum of 3m)?
              • bch 10 hours ago
                Good catch. We've run into a problem somewhere along this journey of comparing the compression strength of a snails tooth to the tensile strength of a spiders web.
                • necovek 8 hours ago
                  So a snail's tooth can only hold a 2m deep worth of Olympic pool (sea)water, but it breaks before you get to a 3m deep pool.

        I think we're still in the right ballpark bit we're headed for the exits.

        .1 lb sugar is 1.6 oz (net), and we'll need to wrap it in paper. I estimate about .5 of an ounce? So we're spending approximately 10% of the weight in packaging. Our nominal 33000 pounds of sugar just got 10% heavier.

        At least we haven't resorted to those little sugar packets, which would be colossally worse!
