    I can voluntarily open my eustachian tubes and hold them open, without needing to yawn or swallow. Makes it much easier to clear the pressure in my ears when changing elevation (like when flying in a plane).

    I can whistle while either exhaling or inhaling

    Idk how special or weird it is but everyone I’ve tried to teach the skill to seems entirely incapable of doing the inhale one

    It’s super useful for whistling complex songs or long bits without stopping, though

    I can trigger a few seconds vertigo attack when I lie down. If I do not think about it when going to bed, everything is fine. But if I think about it, then it invariably comes.

    You know that feeling you get when you listen to really awesome music and your hair stands on end and your skin has like an electric tingle all the way up and down? I can do that feeling at will. It’s called ‘voluntary frisson’, normally an autonomic response. Makes music a real.trip.

        You know how you can end up with crusties in your eyes in the morning? Well that gunk comes partly from your tear ducts and drys there. So sometimes when I blow them out I get some light white mucus as well as tears. When it’s really full it will make tiny bubbles. Lol and it whistles a little so people in the same room can hear it.

        Also as a party gag. Lol

    I can twitch my eyeballs left and right really fast, and not just a little bit - but most of the way.

    Completely grosses people out when I do it.

    Edit: I can even do circles, but not as fast as left and right.

        Neat! Thanks for the name/info.

        I’m the only person I’ve ever met who can do this. It’s apparently somewhat more common than I thought.

        I’m an old man, but I still do it specifically to my sister because she cannot stand it. /sibling rivalry lives on

        I don’t know because I can’t see a thing when I do it ;)

        Edit: I suppose I should make a video of myself - just never have. Sounds like I’ve got plans for the evening :)

      There used to be a subreddit for us. It was called /r/eyeshakers.

      By the way, the scientific name for the eye shake thing, IIRC, is nystagmus.

    I can

    • Bend my fingers back almost to the back of my hand, effortlessly
    • Raise/lower my eyebrows by a lot, even independently. I can make waving motions, as well!
    • Touch the tip of my nose or chin with my tongue
    • Wiggle my ears (though not independently)
    • Roll my eyes up so only the whites at the bottom are visible

      I used to able to touch my fingers to the back of my hand in middle school, but 10 years later I can only bend them back a little less than 3/4

      It was a neat party trick while it lasted, because everyone thought it hurt me to do it lol

        People are often so worried I’m pushing back hard and damaging my joints. So I let them push a finger back softly, then they’re shocked how easy it is, but no longer worried about my joints! 😁

    My left pinkie finger knuckle can hold some tension when I from my pinkie into a claw shape, but then snaps forward. Either that’s unusual or my right hand can’t do that as snappy.

    This is my time to shine, my body is full of useless, I can:

    • gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
    • open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
    • bend my thumb down to my wrist
    • cause my heart rate to spike for short periods even when at rest
    • make a three leaf clover with my tongue
    • click my tongue extremely loudly

      I remember when I was a kid we were all trying to gleek and some of us could do it easily. I never could, so anytime as an adult I accidentally do it, I can’t help but laugh.

        It has “force”, but it’s not very impressive, I can shoot saliva in approximately a 1ft / 30cm arch.

      Tongue clicks are absurdly useful. In my family we use then to communicate over long distances and to find each other in big crowds

      I can also gleek but it’s nowhere near what my grade 11 English teacher could do. I don’t know how it came up in class, but, in front of the class, she turned sideways and made the biggest arc I’d ever seen: maybe 6 feet long

      oh my god, so that’s what I’m doing when I yawn! It started happening a few years ago…
