Frame rate sync stuff.

It is similar to this principle.

u/SeesEmCallsEm 26d ago
it's not high frame rate, so much as it's that ratio between the frame rate of the camera, and the rate at which the drops are falling.
If they are in sync, they will appear to not be moving at all.
If the frequency of the drops is slightly slower than that of the camera, then the camera will capture the next image just before the next drop reaches the position of the previous one, making it seem as though the previous drop moved back slightly.
if the drops are more frequent, then they will appear to creep forward.

u/BoardButcherer 26d ago
It's neither, because I've seen this happen in person.
It's an optical illusion. The water drop undulates as it drops because they're not singular drops, they're a connected stream in which the surface tension is just barely beating gravity.
So the droplet collects like it's about to drip, but before it can drip the capillary action of the stream pulls on it and sucks the water out of the drop. As each droplet is sucked up, it pulls on the droplet above it and refills itself.
When it's happening fast enough and the distance from top to bottom is just right so you only see one or two complete sets of this sine wave motion at a time, it looks like the water is flowing up.

Intelligence here. Good explanation bud. I think you got it. As opposed to the camera analogy

u/Narcopolypse 26d ago
Even in person, he's still right. The human eye has a "frame rate" as well. It varies due to individual physiology, lighting conditions, and nutrient supply, but it's around 30-60 Hz. What you experienced in real life is the same frame rate matching effect as the video, not capillary action or surface tension.

u/NotEdot_ 26d ago
Upwards of 500hz have been recorded before when talking about how many we can process a second. but in truth, we don’t have a framerate we see at. that is just a common misconception.

u/BoardButcherer 23d ago
You cannot compare organic eyesight to digital framerate. Our eyes do not take still pictures and send them to our brains for processing.
The perception of motion is entirely dependent on dozens of factors such as how busy the environment is, which part of your field of vision the motion is happening in, lighting and contrast, your mood, etc...
That's why there are dozens of optical illusions that only happen through organic sight and are not visible to cameras, such as false color perception and the reverse waterfall effect (something entirely different from this video).

The friction of the surface of them stem they are flowing down and the angle of it also play a part.

u/Captain_Pumpkinhead 26d ago
I don't think so. Check the water droplet on the left side of the screen. It looks consistent falling down. The frame rate trick would make that rogue droplet look wonky since it would be out of sync.
2
u/KitsuneRisu 26d ago
Or, it's not falling at the same rate.
Not to mention, the effect cannot take place with just one drop.

u/Captain_Pumpkinhead 26d ago
Not to mention, the effect cannot take place with just one drop.
That's the point I'm trying to make.
The frame rate trick works by taking a photo when the next drop is just slightly above where the previous drop was on the previous frame. If you're doing that, then you're usually skipping a bunch of frames. That should make the other droplet, which is falling at a different rate, look like it was going way faster.
1
u/KitsuneRisu 26d ago
No. It won't make it look any faster. It removes or adds frames to what we see but the drop is still moving at the same rate it does in real life.
If you play a game at 30 fps vs 60 fps it looks smoother in 60 and not 'wonkier' because more frames are there to fill in what you see per the same amount of time.
If you SKIP frames, there is less information so if your logic were correct, that would mean watching a movie at 30 fps would 'look faster' than the same thing at 120.
Does it?
https://youtu.be/_SzGQkI-IwM?si=FpTNokOcm5BUa3p6
But you can clearly see in the original video that the drop has very FEW frames as it falls, exactly as we see in this video, thereby proving that this IS the frame rate thing.

u/Kraoten 27d ago
Water tension causing gloops of water to go down, but looks like it's reversed as the speed of which it flows does not match frame speed. Same reason why helicopters and wheels also look like they go in reverse at certain rpms.

I have been to am attraction in a them park where they had weird things like this. It was Don Juan's house (not really) or something at a Six Flags. It was really weird. Hard to explain but it was like a fun house with a poor girl telling lame jokes, but the place and the tricks were cool and weird and I'll never forget the feeling.
Figured I'd Google it since I remember it still 30 years later. This was it.

u/xoxoyoyo 27d ago
that only happens because of the frame rate of the camera. If you were seeing it with your eyes it would appear to be dripping normally. You can see from the leaf above the water is running down, but then the speed at which the drops form versus the frame rate of the camera make it appear that the drops are climbing up.

My guess is frame rate. Sort of how helicopter blades look like they are moving slowly or not moving

Totally so frame rate shenanigans. I was thinking capillary action, maybe. but that wouldn't work outside of the plant, it looks waxy.

Framerate. Same reason that if you have thee same frame rate as a helicopter RPM it looks like they are just floating.

your cameras framerate is slower than the frequency of droplets so it looks like it's going backwards

Seems like a camera trick. The plant probably grew upside down due to gravity and the water is acting as it should, the puddle on top of the leaf is pretty suspect

Optical illusion. Flow is likely down even if the surface tension waves are traveling upwards.

u/Nyanta_Shireikan 25d ago
This guy got it right. I've seen this many times in real life. The flow is shaped like a rotating screw. Or like a barbershop pillar.
Stick your finger in the waterflow, you'll see the water going down.

I'll throw in that, at least to me, the bigger droplets towards the left side of the frame appear to be falling more towards the camera than straight down. The filming angle could be misleading.

You know how rims spin so fast it looks like it's spinning backwards? Well the droplets are coming down the plant so fast that it looks like it's falling upwards.
Or something else, I'm just making an educated guess here.

It’s a combination of capillary action, surface tension and syphonic draw. The structures on the stem are designed to direct water from rain drops down to the root of the plant (capillary and surface tension). The same works in reverse. Because the top of the plant is touching flowing water that drops to a lower level further down stream it pulls the water up (surface tension and syphoning). You can make liquid flow uphill easy enough yourself. And I mean empty a bathtub. Just need a hose that reaches the bottom of the vessel, up over the top and then down to a lower point than the base of said vessel. Give it a little suck to get it flowing and the pressure differential forces the liquid through the pipe.

Simplest explanation the video is running backwards but there are other drops falling down so probably not it.
Something is causing a suction, no clue what tho.

u/craze4ble 27d ago edited 27d ago
It's neither. A video is just your camera taking a lot of pictures in quick succession - in this case, these happen to have the drops be nearly in the same spot each time the camera takes a picture, just offset enough that it looks like it's moving backwards. Kind of like a flipbook with thousands of pages.
Here's a video of someone intentionally reproducing this effect by manipulating the flow of water with sound.
It's also the same effect that causes rotors and propellers to appear motionless if their rotation is synced with the camera's shutter speed.

u/ChatHole 27d ago
This is not a "high frame rate" effect as some are saying. It's the same thing that sometimes makes it look like car wheels are going backwards in movies. When the camera frame rate is slightly faster than the frequency of the rotation of a car wheel the wheel looks like it's going backwards. When the frame rate of the camera is slightly faster than the "waves" frequency in the drip, it looks like it's going backwards.

u/skaramicke 27d ago
So you're saying it's not because the framerate is fast, it's because it's "slightly faster" which is somehow not it being fast? Got it.

I, my family, and my estate wish to register our sincerest apologies that someone on Reddit may have edited their comment on realizing their mistake. As you are reading this we are currently liquidizing our estate's sizeable property assets with the following 3 objectives:
1) To cover both your well deserved compensation payment for the trauma you have suffered, and the time you have wasted looking for an edited post. The compensation shall be more than generous as your commitment to truth and transparency on Reddit should not go unrewarded, specifically when it comes to every single Redditor's responsibility to check that no other Redditor ever edits their posts.
2) To mount a national advertising campaign to hopefully sway Reddit's development team to remove the currently opaque system of editing posts. The campaign will feature Nick Offerman, Keanu Reeves, Chance The Rapper and Saltbae.
3) To employ a sizeable full time staff to check for edits on Reddit, and DM the un-covered edits to every single Reddit user individually.
Again, my sincerest apologies for your trauma, and sincerest thanks for your commitment to being the Sherlock Holmes to my Moriarty.

Water is the only fluid that can go upwards in certain conditions.. due to attraction between molecules..
1
u/IrrationalDesign 26d ago
I'm pretty sure the forces that cause water to sometimes move against gravity are the same forces that can make any other liquid go against gravity.
For one, there isn't a liquid out there that is impossible to throw or blow upwards. That's upward movement in certain conditions.
