        It could be possible this post is part of some disinformation campaign

          It sounds good and some people share such things without critical thought. It’s like adding sugar to petrol - it doesn’t actually do anything beyond possibly clogging the fuel filter, but the promise of such easy means of destruction appeals to some.

            Stick a potato in a tailpipe and the back pressure will blow up the exhaust manifold!

            I actually did this as a kid and it just pops out like cork.

            Internet said shove it deep into the exhaust pipe with a broomstick.

            When you do this it pops out just like a potato cannon.

            Turns out that exploding gasoline is stronger than the friction of a slippery potato in a steel tube. Who’d have thought.

              Did the potato too, and the engine couldn’t start, the potato just blocked the exhaust.

              Man I heard about the sugar in the gas though, one of those rumors of the day back then I guess.

              I also heard about dig a hole and put fertilizer around dynamite to augment the destructiveness, and that seems to be correct.

              🤷🏼‍♀️

                That’s because nitrates are the main component in both fertilzer and explosives. We’re so lucky plants convert the nitrates to non-explosive forms, otherwise cooking would be a high risk activity.

        I came here from Reddit hoping it would be better but it seems the same low effort/false slop is posted here too.

      It doesn’t fully work if you add enough sugar it technically would but all it will do is just slow the setting process

    IIRC from my material science course, if you really want to fuck up a batch of concrete, you should use salt instead of sugar, cause it’ll crack the concrete with every freeze and thaw cycle.

      It’s the same as with the sugar, you need a lot of it to make much of a difference. Unless it’s reinforced concrete, then the salt in the water will corrode the steel rebar and that will definitely cause cracking.

    Put a couple packets of sugar in about two quarts of leftover bag concrete once just to see how it went. Initially it acted like it had plasticizer and got loose and wet again. A day or two later it was acting like it had just set and a month later I could still crumble the edges off with my thumb.

    Problems with using this for sabotage. Any serious project will have an engineer checking every truck and it will not pass unless the person adding water at the plant was in on it and did some very good calculations. Then the saved samples would immediately give them away in the investigation. During and after the pour there are too many people watching. I would have to say putting brown sugar and salt in the footing trenches the night before it’s poured or spraying (big puddles will get drained) a solution on top of the plastic to look like rain or dew.

      Even if it gets found out, there is still value in destroying an entire shipment of concrete, and making them reschedule a new shipment on another day, wasting a lot of money.

      That’s PROFIT being wasted, a severe crime in the United States of Ferengenar.

    Breaking in the container office building thing and turning the blueprints upside down has better chances of success.

    I never got people screenshoting their response to a post, and posting it everywhere else.

    Especially when it’s bad information.

    It is like self importance is greater than 5 mins of research.

    How much wall does one tonne of concrete give you? Seems like you need tonnes of sugar to properly do this

    You’d need at least 10lbs of sugar per ton of concrete, probably closer to 40. If it’s a full truck it’s probably around 800lbs of sugar to ruin the load.

      Explicitly useful literally, describing a “ton” of concrete is an ambiguous linguistic expression and by using the word literally they denote an actual unit of measurement. Unfortunately they didn’t specify which ton they mean, but regardless the order of magnitude is generally conveyed in a properly useful way.

    You can pour sugar in a car’s gas tank, it will really fuck up the car. Go ahead, test it with your neighbors. They will be pissed af, but as long as you don’t have a flock camera around, just walk up with a mask n shit and they ain’t knowing whst you do if you don’t do what is that you be, obviously.
