    I think there was a science experiments book for kids that dared me to drink water from a glass upside down through a straw while hanging from monkey bars or something. It was meant to show how our body deliberately moves food towards the stomach instead of solely relying on gravity, but instead it showed that I my legs were too weak.

    A shame these experiments are deemed to dangerous nowadays and people have to show their ignorance online, simply because the new metal straws have pierced the brains of anyone who did them.

      I mean I can totally see kids choking on water while doing this too. Yes muscles but I am sure gravity helps too.

    good question actually, the esophagus can squeeze things towards the stomach without gravity’s help.

      It’s even cooler than that: The esophagus can squeeze things towards the stomach against gravity. You can drink water while hanging upside down. You’ll also get a nose full of water because your sinuses would be below your mouth… But once it’s in your throat and you’re swallowing, it’ll make it to your stomach just fine.

      If you wanted to avoid the sinus problem, I guess you could just lay on your back on a steep incline. Not fully upside down, so your sinus cavity is still above your mouth. That way the water would hit the back of your throat where you could swallow it, instead of just draining straight into your sinuses.

        If you slowly inhale through your nose while drinking the pressure from the air coming in will likely direct the water towards your esophagus as well as keeping water out of your nasal cavity.

    I’ve just realised that because of my esophageal dysmotility I wouldn’t be able to eat in space.

      you could set the spaceship in rotating motion, sothat the centripetal forces push you outwards and create the impression of artificial gravity for you.

      besides, why does no spaceship seem to be doing this today, like, at all?

    I’m too lazy to find it now, but one of the tests they tried long before NASA started sending people into space was eating a banana upside down where they figured out the digestive tract can function against gravity.

    There was also an encyclopedia brown story about this in which I remember Geese and Ducks rely on gravity to swallow, therefore they wouldn’t be able to eat in space.

    This was legitimately a significant concern that early space programs had. Like, how well would people be able to swallow in free fall, would certain kinds of food cause problems? The food experiments during the Gemini program are pretty interesting

      Don’t worry, Goku will save us. Well, some of us. When he eventually gets here, after the Z warriors have been beaten up.

      Or if we’re lucky a new strong character will one shot him as his introduction.

      You can swallow things while dangling upside down. The esophagus is strong enough to work against gravity.

      But liquids are a little bit more difficult, because they tend to flow in unexpected places in the mouth/sinuses/nose before trying to swallow.

        Once I had to drink barium while being tilted upside down on a big table while they watched it with X-rays… apparently that’s a medical test lol I didn’t find it anymore difficult than drinking normally personally but it has to do with the strength of your swallow most of all, which is what they were testing at the time.

    I don’t know about you guys, but I just open my throat straight down to my stomach and pour the food in.

    Given how filthy the ISS is, I don’t know if I’d want to eat anything not nuked into oblivion.

        Imagine trying to clean it. You can’t whip out a mop. Showers, wash cycles etc are all no go. Not too mention experiments from plants, chemicals, drugs etc which create their own issues. In some ways it’s clean, but others not so much.

          You can use a vacuum cleaner, but since there’s hardly any gravity most would already get picked up be a simple air filter.

    Oh that’s interesting, I wonder if it’s easier to get heartburn in space? It’s common to need to sit upright to keep the acid down.
