What's something weird and mostly useless that you can do with your body?

I can wiggle my ears. I used to use it to entertain children, but today's children are jaded and cynical.

I found I can wiggle my ears enough to walk my glasses back up my nose when they've slipped down.
- now that's useful!
- I’ve just tried that and you’ve changed my life
- Oh yeah, I didn't even realise until you said it but I absolutely do that all the time
Child me would've loved to see that.
- Adult me would love to see that
I can do it too! it was like discovering a new muscle! I can't do either independently though

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.
- Mine feels more connected to my jaw, I kind of tense my jaw right near the joint to activate the rumbling.
- 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]
- 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?
- Not OP, but mine's not connected to blinking.
- 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.
- Mine is activated by blinking hard.
Yep. I can rumble, and I can click.
Gee, I can do this too! I've tried explaining it to others before but only one person ever got it

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.
A friend taught me how to gleek in 7th grade. I never stopped doing it lmao
click my tongue extremely loudly
Learn Xhosa.
oh my god, so that's what I'm doing when I yawn! It started happening a few years ago...
By shoot, does it have force or do you mean it just comes out?
- 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

I can hum and whistle at the same time. Makes me sound kinda like a Theremin

Same! I liken it to a knock off version of Mongolian Throat singing.
Ah yes, multiphonics.
I love doing this because it sounds like you're charging a laser weapon

that sounds so satisfying

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.

I can do this too.
It's fun to watch people freak out when one can raise his body hair up on command. And since I have an abundance of body hair, the effect is pretty profound.
I think that's the weirdest one I've seen yet
That's actually pretty cool, I haven't felt that in a pretty long time so I'm pretty jealous of you there

Congratulations you have voluntary control of your tensor tympani muscle.
- Should be a filter on tinder
huh. I didn't know others couldn't do this
Is that like the sound you get when you yawn? I can do that too!

I can make my left elbow sound like biting down on dry cornflakes, just by doing a push-up.

That doesn't sound healthy
- I had a complex fracture in the elbow twice, 34 and 30 years ago. There's no pain, no loss of function, and it didn't get worse in all that time.
  Nothing I can really do but hope it will stay like that for the next 30.
- truly

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 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.

This is called Voluntary Nystagmus.
- 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 think we have the same talent. Does it look like your eyes are vibrating?
- 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 :)
Ey wobbly eye gang here
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 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).

Huh I think I can do the same. I always thought it was one of those things that everyone could do.
Same. Sometimes I can't, such as when congested, and it's super annoying and unbalanced.
- yep, I have the same issue when congested.
Feels like a super power when you’re scuba diving and you see all the other divers holding their noses!
Weirdly, I can only do this with my right ear. Definitely helps on airplanes.

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.

cries in has chronically useless dreams that can't even go in a dream journal

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

Psssshhhhhh, look at this guy, existing! Not like the rest of us simulated humans! Buy ovaltine! Just sitting around in society. Pretending to exist, so we can slip subtle advertising into daily conversations. Buy ovaltime! Bet you didn't realize that we're all in the matrix, and your entire purpose for existance is to be made to be miserable. Currency is worthless outside the matrix. We're only doing this to make all in the matrix suffer!!!
Mwahahahaha!!!! Thats my evil laugh! Do you like it?

I can dislocate my shoulder to the music of Billy Joel. The Pawnee Journal once called it, "Why would anyone do this?”

I can flex some muscle in my head that causes a roaring sound in my ears. Not sure what that's for.

Is it the same muscle that lets you wiggle your ears? Because I can do that, and I get a similar roaring.
- My ears don't seem to move when I do that.
Same here. Someone else in the thread said that's your tensor tympani muscle.
I get mine to make a clicking sound. Audible to someone else if they stick their ear next to mine.

There is a tiny hole in the roof of my mouth that i can suck air through.

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

Are you a demon and who summoned you
- Yes

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

Does it sound different than a normal lip whistle?
- Yeah more airy or something I can't really do it on command that well
  Found a video that shows it, didn't know it was a beat boxing thing now I have a goal haha https://youtu.be/_uQDmZmvvSY?feature=shared&t=120
I have this! For ages I've been trying to figure out how to do it on command but so far I can only do it while yawning.

I can whistle in three different ways. The classic pursed lip whistle, a whistle using just the tip of my tongue and the roof of my mouth, not using my lips at all, and then another using the tops of my bottom teeth. I can make decent bird sounds using my bottom teeth, but I can do pretty much any tune I can think of with the pursed lip method. It has been relevant to my life exactly zero times, except to entertain myself.

I've got a tooth gap through which I can whistle. And it's working so well, that I can also audibly whistle while breathing in. So, I can actually whistle pretty much continuously for like 10+ minutes, until my cheeks start hurting. Only really useful getting on someone's nerves...
- That's how I learned the bottom tooth whistle! One of my bottom front teeth was a bit crooked and created a tiny gap at the top, and I learned to whistle through it. When I got my teeth straightened I lost the ability to do the invert whistle and some of my control but I can still do it well enough with the pursed lip method.

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

Hello. I, too, can do this!

Sooo I can cause what honestly feels like a small and constant electrical current flow through any part of my body. If I center this feeling on my chest it is easily more prominent than anywhere else with my head being second. Extremities are dead last. If I am hooked up to a heart monitor I can make it freak out at will. Any location I focus it on tends to want to tense up.

I like to tell people this is the result of me grabbing onto a metal item when I was younger that was still hot. Couldn't let go for a solid 6-10 seconds, can't say exactly how long. What I am able to do feels very similar.

a metal item when I was younger that was still hot
Still hot as in temperature or electricity?
- As in sexy
- Electricity. Hand curled around it to grab and got rooted. I still remember the sensation of my repeating mental command to "LET GO" feeling as if it was slowly travelling down my arm. Weird is a word that comes to mind.

I can inhale through my butthole to fart on command.

What are you, a turtle?
- Heheheheh. Turdle.

I can poop on the floor. But I bet you can too.

Instructions unclear. Anyone know how to clean a popcorn ceiling?

I can roll my R's like a Spaniard and move my boobs on their own but that's it.

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.

A nose flute, awesome! I have the opposite where I can blow air out the other way, but sometimes it will squirt out a stream of tears.

Well, I can still do a cartwheel, it's good for surprising children. Thumbs bend backwards.

I can also reach all of me, which my husband seems to think odd, can put sunscreen on my own back so I don't think it's useless.

Due to an NDA I signed, I am unable to answer your inquiry. Next question please.

Hi yes I'm a big fan. I'd like to know your credit card details please
- I LOVE my fans, I would do anything for them. It's Visa 0251 6623 8874 1000 exp 10/2027

I can rotate one finger at one direction and the other on the opposite direction while pointing one to another, simultaneously. I don't know how uncommon it is but, back at high school, no one else in my class could do it. Totally unuseful skill.

If I’m understanding your description correctly (the image didn’t come through), I can do this too! I heard once as a kid it was impossible and I refused to accept that, so I practiced until I could do it.
Rephrasing to see if we’re talking about the same thing: I can point my fingers towards each other in front of me, then circle one hand away from myself and the other towards myself, and continue looping them in opposite directions. Most people can do it for 1-2 loops, but then end up moving both fingers in the same direction.
- I believe we're talking about the same thing. Welcome to the club!
- Neat! I just tried it and it's hard (harder one way than the other, for some reason), but doable.
My fingers don't rotate unless you count wrist involvement, so I'm a little confused by what you're describing.
- Something like this. Sorry for the poor image. The wrists can move too, I think it doesn't change much.

I can put both my hands In a "pray" position behind my back between my shoulder blades. I can vibrate my eyes. Perpetually crack my right ankle. And pull my arm out of it's socket.

I can vibrate my eyes.
Oh shit. You just gave me a memo of middle/high school. I use to be able to do that. I just checked and maybe if I keep practicing, but it's not there anymore.
Someone I knew did it to me in school. Like just vibrated their eyes while looking at me. Then asked if I could do that. Well no, but it intrigued my young ass enough to figure out how he did it. He told me and after a few days I was able to do it pretty easy.
- That's similar to how I learned! My brother could do it and I was envious and figured it out, he can do it for as long as he wants but my eyes tire after maybe 20 seconds or so

I can crack the knuckles of my big toes at will (only moving my toes, no hands involved).

Me too! But only the ones on my right foot.

I can fit the majority of my little finger up my nostrils. My nose might be slightly larger than normal and my hands are about normal. It just fits up there with a little twist.

Wake up and go about my day.

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.

I can snap with my toes the same way people snap their fingers, but only with the right foot for some reason.

I used to do this all the time. Since I stopped, they don't pop so easily anymore

The trick is to wake up standing, as well.

I can move my fingertip joints without moving the rest of my finger.

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! 😁

I can make fart sounds with only my hands

I can too with my hand and armpit ;)

I can cock both eyebrows one at a time

I can touch my palms flat to the ground while trying to touch my toes

I can bring my hands from the back of my body to the front (and the opposite) while holding them together. There might be a use for this if I ever get tied up.

Me too. the local police even stopped handcuffing me behind my back because I'd just step over so my hands were in front again.
- Deleted
Would've been a nice skill for me to have at one point.

The best way I can describe it is I can make the nerves on the back of my neck, upper back, and shoulders feel sensitive at will.

Deleted

I can bend the last joint in my fingers independently. I also have a small nub on the tip of my tongue, which is only useful in one situation.

Getting peanut butter off the roof of your mouth?
- Yep.
I can bend the last joint of my right hand middle finger independently. Not any of the other ones though. I found out when I was playing Double Dragon in the arcade and smashing the attack button. My finger when stuff with the first joint bent and still smashing the kick button. I didn't know what it was.

I can hear the blood flowing in my head, including hearing my own pulse via the same sound.

That sounds stressful
- Only if you stop hearing it.
have you considered getting your thyroid checked? anecdotal evidence, a former colleague mentioned they had thyroid issues (on the hyper side) and could hear their pulse in their head before solving it. somehow that bit of info stuck with me
- Never heard this, interesting. I usually only hear it in places with low background noise, it kinda reminds me of the sound a CRT TV or something kinda like electricity, it's not really like those things, but it's the closest thing I can think of.
  I can also hear myself blink if I have silence in a room.
  I also actually do have a thyroid condition, but that could be pure coincidence.

Blow bubbles off of my tongue

I came here to say this!
Form a bubble under the tip of my tongue, scoop it up, fold tongue, gently blow.
- Yes! Same exact method lol

Sit in a cubicle for 8 hours a day.

I can do the same by cupping my hand in my armpit then jerking my arm down like a chicken wing real fast. Is this still a thing? I haven't been a kid since the 70's
- I'm in my 20s but totally still a thing when I was a kid.
I can one up you by doing that with my chest
- I can do both of those and I can do it with my collarbone up against my neck. I do it accidentally all the time while leaning over and it catches me off guard all the time...and makes me giggle, because I am very mature.

I can spiral my tongue, so that the front part is fully upsidr down - but only to the left. I can't rotate it to the right at all for some reason, it's like the equivalent muscles are missing.

I can bend my knees backwards by, like, 20°.

Pfff. Everyone can do that..... Two times.

I can make my right arm vibrate by tensing up the muscles in my forearm. I dont me shake really fast. I mean vibrate.like, fast.

Outside of beating my brothers on specific mario party mini games that require repeatedly pressing a single button (or other games that have that use mechanic) or unlocking the cheats in bomberman 64 (needed a turbo controller to hit start repeatedly on the main menu) its pretty damn useless.

There was one Mario Party mini game (i think called domination) where you had to hit A as fast as possible, with each press making a thwomp or "domino" appear in a line. At the end, they all fall down, and you see whose line is the longest.

Some people couldn't reach the finish line. Some could just about get past it. Mine just kept going and going.

Otherwise, totally useless.

I thought that was normal and I just had not learned how to not vibrate, I can vibrate my whole body by tensing up or whatever part I focus on. So I vibrate like crazy when I do the plank... Extremely annoying....
- Mad how everyone has such different experiences and how they shape our outlook on the world and what we consider normal. Like in my circles my arm thing was unique to me. I never met anyone that could do it. But looking at the comments in this post it seems like most of us think our weird trick is unique but there are almost alwas other people who have the opposite experience.
  Interesting.
I can do this as well and find it useful for other devices that use a lot of button presses such as TV volume etc

Not a thing I can, but I once knew a person who could make their eyes go anti-crosseyed, as in left eye looking far left, right eye looking far right, away from their nose.

I can fold my ears twice - so from the top of my ear I fold it towards the bottom of my ear and at the point where it folds I can fold it again across over the first fold.

I can sing really poorly.

Talking.

We have a couple things that run in the family. All men in my direct family (so me, my dad and my brother) can twist our mouths in both directions at once, so upper lip one side lower lip the other side, looks funky. We can also do eyebrow dances with moving only single eyebrows but I think that's more common.

I can usually make my goosebumps on my arm go away by concentrating alone.

I can make them show up on command.
- With your powers combined, you are... Mangoose!

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.

I can diverge my eyes really far, almost equivalent to how far I can cross them. Way easier when I'm super sleepy.

I can snap the tendon over my knuckles kinda hard to where it makes a popping/snapping sound. If I do it close to someone's cheek, it stings like releasing a tiny rubber band.

I can also move my ears independent of one another.

I have a few that some others in the thread have already mentioned, but I can also:

wiggle most of my scalp back and forth
retract the middle of the tip of my tongue so when I stick it out, it looks like an ass
stop peeing mid-stream. Maybe this is perfectly common, but people talk about not being able to just stop, or at least not for longer than a few seconds.

Wtf lol, malfunctioning bot.
- What did it say?

Pop my knees

My knees pop even when I just casually walk. Maybe I should see a doctor.
