    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 can rumble my eardrums. Mostly useless unless i wanna block out some annoying sound but i can only do it for like a minute at a time.

      I think I have the same thing. Is yours also kinda connected to blinking? I can do it without blinking, but closing my eyes at the same moment as rumbling the eardrums feels easier and more natural than rumbling with eyes open.

        I can do it without closing my eyes but when i was younger, I remember closing my eyes or scrunching my face made it easier to do. If you can wiggle your ears without lifting your eyebrows, it kind of feels like its the same muscle group that causes the rumbles. The rumbling sounds like white noise inside my head. Its caused by constricting Tensor Tympani muscle in the ear voluntarily. From Wikipedia:

        Some individuals can voluntarily produce this rumbling sound by contracting the muscle. According to the National Institute of Health, “voluntary control of the tensor tympani muscle is an extremely rare event”,[5] where “rare” seems to refer more to the scarcity of test subjects and/or studies more than the percentage of the general population who have voluntary control. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon has been known since (at least) 1884.[6]

          TIL; I always thought it was temporarily spiking your blood pressure that made that rumble. Now I’m no longer scared to do it

        I do this thing where I pop my ears (like when pressure changes from altitude) and then it’s like I’m hearing my breathing inside of my sinuses or something. When I breathe this way, it effectively blocks conversations I don’t want to overhear. Do other people do this, or am I odd?

          I can do this! I forget the name for it but I can rumble my ears, and then I can also ‘pop’ them if I go a little further. I’m so grateful for it if I ever go through a pressure change, I can’t imagine how people cope without being able to do it.

            Wait a minute. If I hold my jaw right, I do get a very short rumbling apart from my breath. Is that what you guys mean?

              Sounds about right. I would connect this action to my jaw, not anything with my eyes like some others have said. When you say short, do you mean the sound doesn’t last very long? I can keep it going more or less as long as I want.

                As long as I tense my jaw, I guess, but it’s kinda awkward for me. I kinda have to pop my jaw down and hold it. I feel I’m making a silly face when I do it, so I’m not holding it long.

                  I guess there’s multiple ways to hit it. I feel it in my jaw but it’s the same process as wiggling my ears (though I don’t have to do that at the same time if I don’t want to).

          Came here looking for the tensor tympani rumble cause I know it well; not sure what your thing is! If I notice sounds going quiet on a flight I’ll pinch the nostrils shut and make an exhalation effort till I hear a pop in each ear, then sounds are normal. Almost like the reverse of yours.

        I can also ear rumble, it is not tied to my blinking at all, but if I vibrate my eyes while my ears are rumbling they both move at the same ~60hz frequency.

    I just remembered this, I can open my eyelids and look in a direction where only the whites of my eyes are visible. Apparently it’s very creepy

    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).

    Apparently there’s a thing called lucid dreaming that many people try very hard to achieve.

    Most of my dreams are “lucid”.

    I can also, using only my facial muscles, pull my eyelids back extra far so it looks like my eyeballs are popping out.

    Lots of things that ultimately come down to hyper-mobility (thanks Ehlers-Danlos!), including:

    • Lick my elbow
    • Pull my shoulder visibly out of socket (not painful at all, and happens if I carry something heavy if I’m not careful)
    • Pop my hip out of socket while standing (sometimes painful, always somewhat unpleasant, so I’ve had to learn how to not do it)
    • Hold my hands behind my back and pull them to my front
    • Rotate my arm >360°
    • Bend my thumb to my forearm

    I can hammer nails and icepicks into my head. I’m very fire resistant and eat fire. I have a split tongue. I can keep my eyes open for a VERY long time.

    TBF I’m a sideshow and fire performer so I’m cheating

    I can whistle from my throat, I figured out how to do it from yawning and just kept practicing, the wife hates it because it hurts her ears but every time I yawn I have a habit of trying

    If I press on the corners of my eye it forces air down my naso-lacrimal duct (that lets tears drain into our sinuses) and it makes a squeak loud enough for people sitting next to be to hear. I have a built in nose flute.
