This guy just makes me smile!

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!

When a physicist needs to explain chemistry and finds a physics problem that ends up named after them. Science is weird.

who is here after seeing him and electro boom discussing about the mould effect in 2021?

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 audience reaction is priceless

So will it continue to rise until the first bead hits the ground?

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.

MOULD EFFECT!!! YEAH!!! :D

Go ahead, science. Explain that one. We will be waiting.

We’ve got the Mould effect and the Parker square

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.

That ending very nearly didn't land with me, until you sneaked "Mould effect" in at the end :-D

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.

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.

dudee.. u re perfect 😂😂😂

5:40 WOW!

Best TEDx

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.

I just continue watching the video and saw you really know the explanation. Then why you say you don't...

So they explained the way the spheres and links behave by explaining how rods and links behave!

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

The mould effect, nice

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

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.

@ishamalve2242

Steve talked about this in his video, it starts before the chain hits the ground, so it doesn't get a pushback from the ground.

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.

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

Add some centrifugal force (does it exist?) for the bow.

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?

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?

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?

9:58

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.

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.

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.

OK. So because it cannot go down on oposite side, it is kicked up on main side. Yes, good point. Now I understand it.

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.

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?
