NASA's Viral 'Standing Broom' Trick Has Nothing To Do With Earth's Gravitational Pull (cnn.com) 43

Posted by BeauHD from the public-service-announcement dept.
A viral myth from 2012 is recirculating on the web right now, claiming NASA said Monday was the only day you can make brooms stand up all by themselves, because of the earth's gravitational pull. Sadly, there's a reasonable explanation for the "standing broom" trick and it has everything to do with balance. CNN reports: [T]he truth is, you can make a broom stand upright today... and tomorrow and the day after... and the day after that. It has nothing to do with the earth's gravitational pull on a certain day. It also has nothing to do with the vernal equinox (another day of the year when this "magic" supposedly happens). Instead, it has everything to do with balance. The center of gravity is low on a broom, and rests directly over the bristles. Which means, if you can get the bristles positioned like a tripod, your broom will stand upright any day of the year.

        Social media doesn't encourage independent research, It instead encourages people to re-post the same drivel on and on and rewards them for that.

        It's why social media is a marketer's dream - people are easily manipulated and social media encourages such manipulation. Clickbaiting is profitable to the platform owners as well, encouraging them to encourage the practice.

        For some reason, Facebook make people look more stupid than they are.

        Most of my Facebook friends I know personally tend to be rather smart, open minded and with some common sense. We all have our quirks, but that doesn't stop us from having interesting conversations on a variety of topics.

        Hi, I know you posted this as a joke (the misspelling is telling), but I'd like to point out that this is false for any casual readers who see it and think "wow, that's tautology!"
        Intelligence functions on a bell curve, and "average" is a range on that curve, not a distinct point. So more than half of humanity is average intelligence, and less than half are more or less intelligent than average. If you're discussing society, and not humanity, the dumbest humans do not participate in society, and must be

      Without gravity it should quite easily stay upright as well.
      But where does it say it has to be without gravity?

      • Without gravity, there is no "upright".

        • Sure there is. It's what ever you define it as.

            To deep for me.

            But if there is a situation where something needs to be in a state that is called "upright" there will surely be a force acting on whatever object you're dealing with. Otherwise, you'd not say, "The object is upright." You'd say, "The object is floating."

      It gives us a reason to gripe to other (mostly) smart people about our dumb acquaintances and relatives. We all have them, they all share dumb shit like this on social media, we are all annoyed by it. I had at least 5 on my FB feed this morning. At least one was from someone I thought had a brain between their ears.

  • I've heard a similar thing said about eggs. I think it was you could only get them to stand on end on the vernal equinox. In reality, with a little patience, they'll balance any time.

    Now there is a neat trick for determining if an egg is hard-boiled or uncooked. Spin them. The hard-boiled egg will keep spinning for a relatively long time. An uncooked egg will spin for a moment and quickly slow down. The difference being the solid inner core picks up the angular momentum and keeps it going, but the liquid in

      A quicker way is to spin them, briefly hold them to stop them spinning, then let go. The hard-boiled egg will stop spinning. The uncooked egg will resume spinning because the liquid interior still has some angular momentum even though you briefly stopped the exterior from spinning.

    Why yes, yes there is. Gravity is the masons' "god" which solves every one of their mathematical impossibilities!

  • That's precisely what keeps the broom stuck to the floor like that.
    Without the gravitational pull, that broom would float away at the slightest disturbance.

  • I remember a radio DJ from the 1970's that had people standing eggs on end every year during the vernal equinox. He had people calling in months later to let him know that the egg they stood up during the vernal equinox was still standing. He did this every year for almost a decade. It may have been longer.
