I was going to guess a phenomenon called "vortex shedding". Though there isn't much wind, there probably are small convection currents that run near to the ground. As the air flows around each side of the plant, it sheds a little vortex on one side, then the other. This vortex creates a net force. If the frequency of the vortex shedding matches the natural frequency of the plant, it will oscillate as you see.
It is the wind! It's called vortex shedding. It does not take a lot of wind to do it. That leaf was just at the right angle to allow it. You can see it happen to tree leaves sometimes. Look it up.
haha, that's a great video! this reminded me immediately of a hosta (lily) i have at home. it does the exact same thing with its leaves. the plant has dozens of leaves and they're all still but when one of them start oscillating it goes nuts. the conditions need to be just right. little or no perceivable wind but that is enough to get it going. you bring it to a halt and it gets going again within seconds.
I saw the same phenomena once. I think it was the plant (rafias). If you look on google search you will see how similar it is. It was heaving breakfast in a restaurant in Brasil and there was a plant in the center of the room that was moving while there was apparently not any wind. I was astonished. The restaurant owner told me the leafs of the plant move when it catches a very little air stream. So that might be an explanation.
After this summer of no rain for months I would sit outside staring into my woods and how still it was with no wind. I've been watching two different trees with a small branch moving just like in this video and yeah...it's kind of freaky at first. Especially when it slows down, stops and then starts all over again. Its been going on for weeks. Started doing some research and found that it's some sort of resonant energy in the trees that it needs to expel. Keep in mind that trees are living things and are designed to move and sway. To sit still for so long causes them to build up unused energy. They need an outlet. Resonant energy. Pretty amazing to watch.
Ok I get that, but this would mean that the tension in the stem is VERY weak for the stem to bend under such a light force the wind applies to it. But when you see the speed and vigorousity [/strength, don't know how to say this] with which it pulls back, it seems that the tension would be quite strong.
I would say there is a mole or something underground. Chewing it makes it swing. Like molerats. They never come above ground and they pull these plants down into their burrows. Quite awesome.
We spent about 15 minutes poking and prodding that plant and nothing inside it. If it was wind it was still pretty crazy how much it was swaying around compared to everything around it. We also went further down the trail and it was the only thing swaying that much.
It has everything to do with the shape of that leaf. It was long, slender, lightweight, and perfectly aligned to the direction of the breeze. It takes almost no wind to move a properly-designed airfoil. This was a very odd occurrence, but nothing weird.
Did you solve this mystery? We are in Murrells Inlet SC and witnessed this same thing here about 10 years ago and then again in the same area today. I tried the first time to figure it out with no luck!
Perfectly normal action from the plant. Oldies had heaps of them in the garden out back. All swaying side to side. Looked like a crowd of green swaying arms from afar. Nothing weird here. Just the slightest amount of wind starting a type of “metronome” effect.
it's quite simple, it is heat that is causing it, if you look on the ground, there are spots where sunlight is hitting the ground causing the heat to reflect up and make the plant move. if you have a similar plant at home with leaves the same shape, try putting it above your radiator, it will do exactly the same thing.
They claim there is no wind blowing through it, I see the neighboring plants waving from the wind blowing through them. And the swaying plant responds along with the rest of the neighboring plants when the wind increases. Further more, that leaf was not the only one swaying back & forth, above that leaf, further back on the background, you can see a blade of grass also swaying back & forth. Love it how they delude themselves. "It's not wind," he says at the end. While panning across the field with plants on the background visibly & clearly swaying by the wind. 🤗Some people sure love to fool themselves!
You said there is no wind, but we can see other plants moving very little, There was some wind. The trick is that the plant have an aerodynamic shape that catchs more efficiently the weak wind.

actually I think medicbr549 is right. I study control systems and this phenomenon is known. A little bit of "energy" (through wind) can make a "system" (plant) oscillate in it's natural frequency. Through the special geometry the wind adds a tiny little bit of energy every period of swinging. Best other example: Tacoma Bride (youtube it) But what a damn coincidence, it's awesome :)
First thing that comes to mind is a mole or a gofer or some other underground dwelling creature eating away at the roots. Unwittingly wiggling the top as it chomps away. Must have a lot of roots though to keep it busy making noms for more than 20 minutes. Either that or it's taking really tiny but voracious bites.
From the right actually, between 00:30 and 00:32 you can see a line of string shining from the right and a little bit up. It's very subtle but once you see it...
I'm 100% sure its the wind that does this. The curvature of the leaf makes it go one way, then the leaf twist a few degrees so that the wind shifts it the other way, and then it repeats.
You ever see that video about the ghost swing? where it moved on it's own, but the other swings around it were still? I think at one point it was on fact or faked.. I think this has a similar explanation. The plant is just at the perfect angle, the perfect size and shape to move from the wind where as the other plants wont be affected.
All things we see are made up of wavelengths, and are slightly different, so even the ones near this one that are not moving are a little different. This is obviously being affected by some sort of wave form maybe even eminating from the people taking the video. It apears to be grooving with the wavelengths it is tied to. Very cool video. :) Love it.Or maybe its listening to "Feel Good Inc" from Gorillaz, jamming out! :)
Also my mom saw something similar but it was going up and down instead she only got the last piece of it on video but its moving less. She swears that the plant was vine was standing up but went down.
To me, it looks like they haven't attempted to go round to the back of the plant or to open it or pull it out or anything, which they should have done I know I would have, just to see because if this is a real plant an it's the first of its kind it need to be documented. Have specialists been to the site of the plant? Have they even told where it is??
se nota que cuando mas se mueve es cuando mas brisa hace es algo normal no es nada raro,si es gracioso no acostumbramos a ver a una planta asi pero no lo hace por si misma
Was about to post about the wind being at the right speed/angle to make it oscillate at it's natural frequency but then saw Torben's comment. You can think of it like pushing someone on a swing... the swing of the person gets bigger and bigger as you push them at the right frequency. Here's an excellent example of what a bit of wind can do: ruclips.net/video/j-zczJXSxnw/видео.html
both of them, especially the man, need a career change to actor. Its not hard to detect fake responses and he is genuinely amazed. There is a scientific explanation due to the curvature of the leaf. There was an obvious but barely detectable breze if you look. The leaf was capturing the air just right.
Well that is a new leaf, from some variety of palm. It should have something to do with how the shape of the leaf interacts with what little breeze there is. I'll give you this, it definitely LOOKS freaky! Can you please make a big clear box out of fiberglass or something, so we can see whether it moves in the complete absense of wind? I was so excited that I made a model of the leaf and stem. It's not scientifically accurate enough. Please investigate it at the source. Hooray for science!
I'm guessing it was creping him out, because it was freaky. It was freaky, and it was creeping him out. It was weird, freaky, and creepy. Oh my god. It was freaky.
verdade isso é uma espécie, pois aqui no brasil , mais precisamente em curitiba na região de morretes eu vi uma dessa ! não é mentira existe , é uma categoria de planta que se mexe, assim como tem as carnivoras e etc... Legal , sinceramente, impressionante !!!
Ok, seems plausible, and yet it doesn't. If the tension causes it to pull back and swing, how comes such a light breeze can overcome the tension in the stem. There's no way the tension just appears once it's bent. Coud you explain that please ? I'd love to know !
I was going to guess a phenomenon called "vortex shedding". Though there isn't much wind, there probably are small convection currents that run near to the ground. As the air flows around each side of the plant, it sheds a little vortex on one side, then the other. This vortex creates a net force. If the frequency of the vortex shedding matches the natural frequency of the plant, it will oscillate as you see.
There is a grub/worm inside the stalk. When the weather heats up it starts getting more active, causing the leaf to sway.

Resonant energy.
Pretty amazing to watch.
I watched a branch on a scrub white birch do the same thing.
This has happened to me a few times... I don't know for sure, but, when it happened as a kid my parents always told me it was a nature spirit
Jethack: Thats freaky
Plant: Can't stop dancin
Ok I get that, but this would mean that the tension in the stem is VERY weak for the stem to bend under such a light force the wind applies to it. But when you see the speed and vigorousity [/strength, don't know how to say this] with which it pulls back, it seems that the tension would be quite strong.
This is so true ! I have had this happen to me the other day in my baywindow ! Interior plants .
What a happy and fantastic plant... i love it !!
this is called "flutter effect". The shape of the leaf interacts dynamically with the air flow making an unstable motion.
I would say there is a mole or something underground. Chewing it makes it swing.
Like molerats. They never come above ground and they pull these plants down into their burrows. Quite awesome.
Thanks Torben and everybody Else's theories and ideas. It was definitely fun to watch whatever was going on, and a cool ending to a good ride.
First
There was a tiny bit of wind, but the plant was moving so violently for the amount of wind.
Theres a plant like this in my backyard, and it's got one particular leaf that always goes crazy like this. Just the right shape in the right spot.
Plants are testing out their new muscles!!! Soon we will see treants running around! EVOLUTION!!!
We spent about 15 minutes poking and prodding that plant and nothing inside it. If it was wind it was still pretty crazy how much it was swaying around compared to everything around it. We also went further down the trail and it was the only thing swaying that much.
It has everything to do with the shape of that leaf. It was long, slender, lightweight, and perfectly aligned to the direction of the breeze. It takes almost no wind to move a properly-designed airfoil. This was a very odd occurrence, but nothing weird.
All these years later and I still am on the hunt to find one in the wild.

Sand fleas having a pillow fight...
Perfectly normal action from the plant. Oldies had heaps of them in the garden out back. All swaying side to side. Looked like a crowd of green swaying arms from afar. Nothing weird here. Just the slightest amount of wind starting a type of “metronome” effect.
Yep, and to add to it. The vortex shedding is matching the natural frequency of the plant
it's quite simple, it is heat that is causing it, if you look on the ground, there are spots where sunlight is hitting the ground causing the heat to reflect up and make the plant move. if you have a similar plant at home with leaves the same shape, try putting it above your radiator, it will do exactly the same thing.
hes got a song in his head and hes super happy.

Like when a dog wags it's tail....It's happy to see you!
I have seen the same thing on a nature trail in Florida! I was just as creeped out lol:)
It's the plant's resonance frequency. Just a little bit of energy at a the right frequency can make bit results.
You said there is no wind, but we can see other plants moving very little, There was some wind. The trick is that the plant have an aerodynamic shape that catchs more efficiently the weak wind.

A gopher is messin with you! Or a sinkhole is about to give way.... Run!

I'm 100% sure its the wind that does this. The curvature of the leaf makes it go one way, then the leaf twist a few degrees so that the wind shifts it the other way, and then it repeats.
you can see other plants, ones above the super swaying one being blown by wind too.... its the curvature of the leaf
I worked in horticulture for long time and Ive seen this dozens of times. Hosta, black walnut tree, fern, etc.
So what is it? How/Why is it happening?
You ever see that video about the ghost swing? where it moved on it's own, but the other swings around it were still? I think at one point it was on fact or faked.. I think this has a similar explanation. The plant is just at the perfect angle, the perfect size and shape to move from the wind where as the other plants wont be affected.
they are EVOLVING. it will in the coming generations, be capable of autonomous movement and travel.
All things we see are made up of wavelengths, and are slightly different, so even the ones near this one that are not moving are a little different. This is obviously being affected by some sort of wave form maybe even eminating from the people taking the video. It apears to be grooving with the wavelengths it is tied to.

Headbanger Plant just Jammin out to nature.
That plant is a paid actor
Also my mom saw something similar but it was going up and down instead she only got the last piece of it on video but its moving less. She swears that the plant was vine was standing up but went down.
The small winds are just blowing it back and forth and again and again
Then you can see that the wind picks up again, the branches in front of it begin to move again, and the plant resumes it oscillation.
To me, it looks like they haven't attempted to go round to the back of the plant or to open it or pull it out or anything, which they should have done I know I would have, just to see because if this is a real plant an it's the first of its kind it need to be documented. Have specialists been to the site of the plant? Have they even told where it is??
se nota que cuando mas se mueve es cuando mas brisa hace es algo normal no es nada raro,si es gracioso no acostumbramos a ver a una planta asi pero no lo hace por si misma
Ah, so by "no wind" you mean "wind", and by "nothing else is moving" you mean "other things are moving"
So is there something about the natural areo-dynamic design of the frond that has been studied for other possible applications, do you know?
something tells me it's been pollinated
Why has nobody taken one of these plants home and potted it.
I could never just shrug my shoulders and walk away from something like that.
I was watching this with 'meh' but in the end of the video I'm laughing because of the way you laugh, man. LOL.
The reason is that it has a structure similar to an airplane wing thus expressed the air pressure inside easily
Was about to post about the wind being at the right speed/angle to make it oscillate at it's natural frequency but then saw Torben's comment.

Here's an excellent example of what a bit of wind can do: ruclips.net/video/j-zczJXSxnw/видео.html
its one of those moving plants they sell at Walgreens.
Resonance. You can plainly see there is some breeze.
Someone should try pulling or digging it out. For all you know, it might be Chikorita underneath. If that's the case, I call ownership!
The plant is obviously being moved by two opposing forces, IE, two people pulling a string back and forth on both sides....
Doesnt it make more sense that his "wife" is just tugging on some string.
It's a Happy Dancing leaf😊🌿 dancing to music of the earth that our ears don't hear... frequency😮
Hello from IAB! This video is terrific, thanks for sharing it with us.
I would've guessed the wind, but none of the other plants seem to be affected...
both of them, especially the man, need a career change to actor. Its not hard to detect fake responses and he is genuinely amazed. There is a scientific explanation due to the curvature of the leaf. There was an obvious but barely detectable breze if you look. The leaf was capturing the air just right.
I wonder if something was in the soil causing it, like a mole?
It's just happy to see you, bro.
I had this happen to me today in Florida. Any explanation?
自分も一度だけこうやって動く植物を見つけたことあるよ。
その時はビデオカメラも持ってなかったし、携帯電話も普及してなかったころだからこうして動画を撮れなかったのが残念だった。
It's clearly hearing Guiles Theme in a subsonic frequency which we can't hear, because Guiles Theme goes with everything...
yeah this is done by wind. resonance and oscillation and stuff like that, just like that famous bridge collapse caused by wind.
there is an insect inside it making it sway. This happens all the time when they get trapped and cant find their way out.
I imagine that the plant is top heavy and the light breeze is making it sway and it gathers speed?
There's a bug flying around inside the plant tube
This plant is doing the Harlem Shake lol
I think the fundamentals that we could pull from this plant for green electricity has already been invented. It's called a windmill.
Well that is a new leaf, from some variety of palm. It should have something to do with how the shape of the leaf interacts with what little breeze there is. I'll give you this, it definitely LOOKS freaky! Can you please make a big clear box out of fiberglass or something, so we can see whether it moves in the complete absense of wind?
I was so excited that I made a model of the leaf and stem. It's not scientifically accurate enough. Please investigate it at the source. Hooray for science!
My first thought is that the plant is luring you to not pay attention to your surroundings. Little green men or Bigfoot is watching
why the same others plants doesn't move???
ok now all u gotta do is harness its power to create free energy
Gave that plant a Molly
It's a very happy plant!
Saw same thing today in Australia
I'm guessing it was creping him out, because it was freaky. It was freaky, and it was creeping him out. It was weird, freaky, and creepy. Oh my god. It was freaky.
Resonant vortex shedding. Wind bro.
Coordinated with the wind!
there is a bug trapped inside the leaves. its resonance that is causing it to swing.
verdade isso é uma espécie, pois aqui no brasil , mais precisamente em curitiba na região de morretes eu vi uma dessa ! não é mentira existe , é uma categoria de planta que se mexe, assim como tem as carnivoras e etc...
Legal , sinceramente, impressionante !!!
Yeah he's just moving from one side of the plant to the other fast enough to make it sway that quickly WHILE HOLDING THE CAMERA STEADY LMAO.
Ok, seems plausible, and yet it doesn't. If the tension causes it to pull back and swing, how comes such a light breeze can overcome the tension in the stem. There's no way the tension just appears once it's bent.
Coud you explain that please ? I'd love to know !
No vertical videos...
mother nature has a tail, she happy.
that plant lifts.
Put a little sumbrero on it and play Jump in Line
someone near by has a string attatched and is pulling it :) most likely to the left since it wasnt panned left in the video at any time
うちの庭の葉蘭も揺れます。風もなく、周りの葉は全く揺れていないのに。面白いですね😊
Now we just need to add dance music to accompany it.
This reminded me of the singing bush from Three Amigos, except it's not singing..
wow lol thats crazy weird! seen this before on MrMBB333 channel but not from 2013! i dont think any way. maybe you should show this to him?
I AM GROOT
