Steve - Thanks for the shoutout in the story about the plastic beads. I originally found this in a very old book of "parlor tricks" from the late 1800s using a long string of beads. You've taken a simple demonstration and turned it into something amazing. That's the Mould Effect.
This meme needs to be revived! Make it reach the holyness of memehood! by which I mean we need to make it a mainstream meme! Im a parker^2 supporter!!!
Another testable prediction of the theory as described is that the jar should weigh slightly heavier as the chain is falling than it does when the chain is at rest in the same position, e.g. if it's just draped over a hanger at the same height and held in place. Has anyone tried to measure this discrepancy?
The best way to test if the jar gets heavier would be to pull the chain from the beaker in zero gravity and see if it moves backwards, Steve explained this in his later video on his channel. Apparently, it's hard to get ISS scientists to pull a chain out of a jar. So instead, he laid the chain out on a table so there was no gravity pulling the chain in the direction of the pulling of the chain, and the chain did, in fact push the rest of it backwards. So, cheap proof.
The idea that metal beads become inflexible on application of a larger force was literally my first thought when he showed them rising up. I have spent actual hours just playing with metal bead chains and trying to meet two beads which are only one away from each other. (And if I'm being honest, I like the scraping noise it makes when I can't) Seeing the self syphoning was so fun! And the whole story reeks of a Physics geeky scientific business. I would have never guessed they would rise more if the height increased!
First thing that the metal beads reminded me of was 'Hey, I kinda did that last night while vacuuming & yanking the power cord of my vacuum, to free it up from a table leg".
The Mould effect is from the transferring of momentum between the beads and the rigid rods inside of them. As the momentum is transferred, based on the speed at which they pour out (Weight+height, the farther they fall the faster) as the rods lock in the balls as the string is pulled it creates the rising and spiraling out of the jar. In other words as the balls are being pulled out of the jar, the rigid connecting rod "flicks" the next ball in the string UP rather than PULLS it straight out. In being flicked UP, the ball catches air, and momentum forces it into the air rather than straight out of the jar. If you focus a high speed camera directly at the balls as they are being puled out and follow what i just said it will make sense.
its the speed the beads have on their way up from the pot that makes them go above the top, they have angular momentum going up from being pulled out and the speed the chain is falling/ rising determines the height it goes over the top.
I am just a dude in new Mexico but I'm thinking that maybe it isn't the surface it sits on. I imagine that the increasing weight of the chain falling over the edge of the pot increases impact force so drastically that one or a few bounce high enough that it begins to pull the chain from both sides of the mould arch. A continual pull down and a really intense bounce up that never truly reaches its apex at the same time due to the simultaneous drop. Maybe the energy transfers through the chain so balanced that it creates that very fascinating effect. Imagine taking this chain and placing it flat then trying to make an arch roll through it. You initially pick it up above its sitting point and as your still rising you slam the high end of the chain to the floor and it will whip into an arch motion that continues until the energy or rope run out . Now imagine the first end that you throw down never hitting the ground, the whole chain staying in one confined area opposed to a long straight line and add all off that momentum into a bounce that makes the other half of the chain lift at the same time. I'm no scientist but I'm sure if one read this they could possibly turn theory to law and one day find a use for this.
As an engineering student i just thought and felt that its..just momentum conservation. As chain has constant length l Thus its falling rate should be equal also while coming out of the container..with same velocity as L1=l2 So falling rate should be dl1/dt=dl2/dt Soo thus the for velocity of raising of chain is same as falling this momentum cause chain to raise due to its vertical momentum.. But yeah i m pretty sure i am wrong but ur explaination makes more sense..mine should be wrong bcz people would have already said that
Amazing. I hadn't realized EU was the first to film this slo mo. I had seen the original video shared around social media a lot, and had assumed it was a well-explained scientific fact discovered in the early Newtonian days. Glad to see things as weird yet as cool as this can still remain undiscovered today.
My thought was to test it by putting the chain of beads on soft foam rubber. Presumably they'd be able to push down successfully and they wouldn't produce a fountain. Much cooler to have a long drop and a much bigger fountain.
Wouldn’t it be the rigidity of the beads hitting the ground that would create a shock up the rest of the coil? The first few inches hit the side of the container creating the upswell; then once they hit the ground pushes it not only upwards but in wilder directions.
Metal beads rise higher because of their weight. The effect is greatly induced by the fact the beads have a minimal radious and the velocity of the movement pulling down with the original force being vertical above. You can do the same thing with a huge, heavy chain fed over a wall.
@@fins59 Man, I have looked for weeks and can't find it. The title was something like " An unusual phenomenon" or "Odd effect I can't explain". A dude just said " this is a weird thing I can't explain" and started a long logging chain falling over an embankment/ retaining wall. When it stopped, he just said "well that's it...". It behaved just like the bead chain... I'll keep looking - I'd like to see it again!
Is it just because of the momentum of the beads leaving the jar? Does it work with anything else? Does plastic not exhibit this at all? Does the theory explain why plastic doesn't work?
I have a question, does the Mould effect start before the first beed of the chain hits the ground or after? Couldn’t help but noticing that the slow motion footage didn’t include the ground in the frame and that the higher the drop was, the stronger the effect appeared to be in each demonstration.
My initial thoughts were that the longer string of beads that were accelerating downwards applied a strong force towards the beads (short string) being pulled upwards, thus the upward acceleration. So by argument, the higher he raised the beaker, the longer the string of downward accelerating beads would be, thus the higher the beads would fly up. I didnt think that the beads were pushing on the beaker and that the beaker was pushing back.. but I guess that could be verified experimentally, by resting the beaker on a weighing scale, to check if the force was really present.
Thought Experiment: Since the height of which the chain jumps out of the beaker depends on how far the drop is.... What would happen with a REALLY long chain, that REALLY strong, that was dropped into a huge gravitational pull (such as a black hole)? Would the chain explode out of the beaker super high?
You add your energy into the chain by pulling it, starting the effect. The effect is when there is enough weight outside of the beaker that the falling chain has enough energy pulling the rest of the chain up the lip of the beaker
Proper explanation for the Mould Effect. I'm not satisfied at all with the scientists explanation of the causes of the "Mould Effect". Here is what I think is going on: Any length of static chain hanging from the container is obviously putting a net force on the lip of the container equal to the weight of the hanging chain plus the short piece of chain rising up to the lip. Once the chain is is free fall there is no weight at all being contributed from the hanging chain - the only weight comes from the small piece rising from the container to the lip. But now we have considerable centrifugal force from the relatively sharp turn at the top as the chain changes direction. This force easily overcomes the small weight amount of the rising length of chain. Steve - we can cut a deal - call this the "Mould-Nebauer" Effect and no no more correspondence to be entered into (wink). Love your channel - keep them coming. John Nebauer
If Cambridge is correct then the same thing would also happen with an anchor chain, no? If the or mass of the balls is increased does that affect the height of the curve? From your slo mo video there appears to be a Corollas Force applied to the system. What is the velocity of the chain at the apex? Does it change over time. What if the chain were able to reach it's terminal velocity?
is it not just the inertia of the beads going up? the bead accelerate up because they are being pulled up, then continue to move up until they are slowed down by gravity and go back down
I vaguely remember a toy when I was a child, it was two wheels within a housing, like a staggered baseball launcher, with a rainbow string, quite light, and soft. The wheels would cause the string to be locked into place just like with these beads here, the thing is, it seems like they have focused alot on beads, when this phenomena is not exclusive to beads, and as it can be done with a loop of string all in constant motion, i wonder about their theory a little more
Idt that explanation is quite right. They are assuming that the fulcrum would be the center of the rectangle, however, in reality it would be the bottom left corner. The better way to think of it would be to imagine that rectangular object bending.......
No, because at a certain "bending angle" it would get rigid, behaving just like what's shown, which is shown for a more clear explanation. And regarding the fulcrum, yes, it would be the bottom left corner, but just because there is a normal force pushing that point up to remain still. If there was no other force besides the previous bead pull force, it would rotate around the center, which is the center of mass.
so it's being pushed up by the chain's container - like to see the container on a scale to confirm. Also the rise of the chain depends on the height of the fall - sure like to see an experiment with 1000 feet of chain on top of a 50 story building. How high can it go?
I’m not quite convinced neither with the “scientific explanation”, nor with saying that the beaker pushes the rods. I rather think that the best explanation (also for the corkscrew phenomenon, not explained by the rod pushing beaker mechanism) is inertia. Once the beads start moving upwards because they are pulled by the ones already moving (initially still within the confines of said beaker), they have upwards movement, and so (upwards) inertia … give this a thought.
Yes, I do agree! I commented this yesterday also, but I think my comment was blocked for some reason (possibly due to a link to a video was inserted). If you want to see a simplified computer simulation I've made of this showing inertia is maybe the most probable explanation, please go to my channel and take a look at it (the first split second before the siphon has stabilized.
I get why that theory would work with Rods but why would it work with spherical beads. Wouldnt the beads not create the downward force because there spherical?
Ein Effekt der Trägheit, die einzelnen Kugeln werden über die Kante des Gefäßes nach oben gerissen (Impuls) und finden erst nach beenden der eigenen Trägheit den Weg nach unten. Da das ein wenig dauert entsteht dieser Effekt. Je höher man steht um so stärke die Kraft (der Impuls) die die Kugeln aus dem Glas reißen und daher auch um so stärker der Effekt.
I disagree with the paper, for that to be the case the chain would have to be at it's minimum bend radius for the whole rise which it doesn't seem to be
I like this guy but God he's dying out there and it ain't necessarily his fault. I've worked literally hundreds of comic shows and there is one thing that stands out clearly - an audience can sometimes be too shy, too uncertain or too whatever to laugh and, if you don't get them to just giggle a bit before a certain point you can never get them back. Who, other than a drunk or the artists mother, has the bottle to be the first to laugh.
I have been following his channel for a while (got recommended from other RUclipsrs). It's pretty entertaining and educational. Doesn't get a lot of views, though.
rope will do the same thing. even fishing line in an open cast reel does it real good. the weight and speed of the cast will booger the line unless one applies a slight amount of drag with your thumb on the line as it runs out.
+dusty johnson Yes. This is very similar to holding a rope... then moving one end up and down quickly. The resulting wave that travels through the rope appears to be same effect as these beads.
I think the effect happens because the beads have inertia. The beads want to follow the chain as it gets pulled down, but the only way to do so is to go up over the rim of the beaker. Because the beads are metal, and have a decent weight to them, they keep most of their upwards inertia and go up, against gravity. The higher they go, the faster they fall back down, meaning, the next beads have even more inertia and henceforth, rise higher and higher. A way to test this theory would be to try the 'Mould Effect' off of a flat surface.
I was wondering the other day whether that flexible shower pipe would work the same on a large enough scale, after all it is made of sections which have limited flexibility

so it's being pushed up by the chain's container - like to see the container on a scale to confirm. Also the rise of the chain depends on the height of the fall - sure like to see an experiment with 1000 feet of chain on top of a 50 story building. How high can it go?
The loss of weight of the chain from the jar would cancel out any "push" making it impossible to measure the "push" down.

Quite the opposite. I'd say he performed better than what most would have infront of a bunch of nerds.
Dr. Biddle is in the audience
rope will do the same thing. even fishing line in an open cast reel does it real good. the weight and speed of the cast will booger the line unless one applies a slight amount of drag with your thumb on the line as it runs out.
+dusty johnson Yes. This is very similar to holding a rope... then moving one end up and down quickly. The resulting wave that travels through the rope appears to be same effect as these beads.
But then again, he said it only happened when he used metallic chain. Why didn't it happen with the other material?
Because the plastic ones are fully flexible.
He's so cute 😘
dudee.. u re perfect 😂😂😂
I think the effect happens because the beads have inertia. The beads want to follow the chain as it gets pulled down, but the only way to do so is to go up over the rim of the beaker. Because the beads are metal, and have a decent weight to them, they keep most of their upwards inertia and go up, against gravity. The higher they go, the faster they fall back down, meaning, the next beads have even more inertia and henceforth, rise higher and higher. A way to test this theory would be to try the 'Mould Effect' off of a flat surface.
So here it's were all begin, hello from the future of the big bet and chain fountains
ys man! vibe
I was wondering the other day whether that flexible shower pipe would work the same on a large enough scale, after all it is made of sections which have limited flexibility
5:41 lady on the right edge of the screen really wain' for the experiment - 6:09 she like it, really :D
7:05 and she is in the middle of the screen and it seems she likes it very much to the very end :)
9:03 what is going on in her head, we can just imagine :D SCIENCE!
