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.

      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 12 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?

    • Tagbert 2 hours ago

      Both are in the same order of magnitude.

  • kbelder 19 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.

  • bjt 19 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.

  • necovek 14 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.

    • yallpendantools 12 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 6 hours ago

        > imagine the possibilities!

        Space elevator?

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

    • dyauspitr 4 hours 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.

            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 14 hours ago

            Aren't there significant differences in allowed depth (from minimum of 2m to maximum of 3m)?

            • bch 13 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 12 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.
