Thanks to @SteveMould for battling this out with me! Every time I feel I know something a debate like this shatters some of my thoughts and makes me think harder. Make sure to check Steve's first video: and NOW his second video: that is way more convincing! Does it mean I may lose my 10000 cents?! Eh, it is for science so that's fine. But I haven't given up just yet!

Hey @electroBOOM "the coolest guy ever 😁 . We can use a soft base(a cushion) to absorb the force pushing the chain down. And if still rises then it proofs that force is not the the reason for that effect. though that force exist.

Is this just centripetal acceleration? Mv^2/r? As the beads fall, the velocity keeps increasing and for the centripetal force to stay constant (force of gravity) , the radius must increase.

It's centrifugal force... The chain moves through an arc, which is the top half of a circle, so it only produces an upward force which lifts the chain. The key to the whole thing is very clear at 15:44, just watch how the tail of the chain whips the last few pieces out. It is this conservation of momentum that provides the force everyone is missing.

*Here is the solution.* It's so simple actually. In your analyses, you have both failed to examine how you set the chain off. The chain is telegraphing the information of your initial flick. The answer is in comparing the start and end. It's not different from the effect you get when you suddenly flick a rope up and down, making a little hill travel the length of the rope. The flick is carried the length of the rope, transformed into a hill, which is suppressed as it too tries to recreate the flick, and so on (although this is in reality a smooth transfer of forces), culminating finally in the release of the flick at the end of the rope, which is really a telegraphed version of the flick you gave the rope (or chain) at the beginning. You start with a whip cracking motion and indeed at the end the chain behaves like the end of a whip. You would see this better by using a very short chain of say nine inches (and not letting go). The transfer of force works better in the ball chain because it transfers forces more efficiently.

ElectroBOOM is correct. And 11:20, the chain probably didn't rise because it weighs more than twice that of a ball chain on top of everything ElectroBOOM says. 13:14, watch the chain that is moving closest to the chain that is still stationary, it's visual ASMR lmao.

Ould this have some relation to what happens when you whip opes and chains causing a wave to travel down it. the wave in this case is stationary and the chain is moving.
codemiesterbeats Acum 11 Zile
I agree with your interpretation... it seems to me that it is just creating a "whipping" motion as it falls off the edge and it rises to a certain point... the whipping motion just adds to itself like constructive interference in a wave. ( I would guess that that will top out at a certain height, allowing the falling part to reach terminal velocity) Not sure if the business end hitting the ground would change things much... I guess it would have some effect. It is an interesting thought experiment. Edit: upon watching both videos I can't say either are wrong. I am wondering if the distance of the beads spacing has something to do with angular momentum imparting a separate whipping motion in the "pile" It is pretty interesting conversation lol

The effect happens with normal chain, like 3/8mm BBB anchor chain. That is why the chain coming up the howse from belowdecks jumps the gipsy if you free-fall the anchor. If that happens you may lose the whole anchor+chain. When dropping anchor one releases the brake of the gipsy just enough to let out the chain moderately slow. It is simply the chain accelerated upwards continuing motion upwards You could run a random chain over a pully suspended by fish-scale. When the chain runs the scale will measure less than with the chain at rest.

You're both 33% accurate Newton's second law of motion. What you 2 are bickering over is how a barrier will guide the chain, and yes the chain can act as a barrier towards it's self! Tension and friction are also very pronounced forces with these chain experiments. Sir N's 2nd law is also why the gyroscope structures in your ears can stabilize you on a bicycle and why at a certain speed threshold you can ride with no hands.

I'm not math guy, or even an engineer. But I picture a pulley in the loop. As gravity pulls down the falling chain, The chain on the opposite side of the "pulley" is pulled upwards. "The pulley" is caused by the turning radius of the chain, the momentum of the chain moving upwards, the time it takes to change direction, and rotational torque of the direction change. as the chain moves faster the centripetal force increases which then increase the "turning radius" of chain.

Your explanation seems obvious and is the same conclusion I came to (though, without the math. Never had the head for that). Of course, that I came to that conclusion kinda makes me worry I'm wrong, since I couldn't write or solve a physics equation to save my life. Just seems so obvious that the speed of the falling chain pulls upwards on the resting chain with such force that it has to launch into the air, and since it's part of the chain it has to curve over and be pulled down. Doesn't seem mysterious at all. But, I guess I should go watch his video too.

To be honest I thought it was plain centrifugal inertia: the velocity of the chain restricts how tight a radius of bend it can take - just like a car travelling at 100 mph can't take car park level turns. Having a limited bend radius helps getting it started instead of grinding to a halt dragging on the side of the glass, although provided you can get enough speed, I can't see why you can't achieve this with an ordinary rope.

its all about inertia ... the higher mass of the chain falling towards the ground provides more than enough energy for the part of the chain going upwards towards the rim of the container....the velocity of up moving part is higher than the falling one which provides just enough energy to slowly increase the height of the system so that the system can stay in equilibrium...... an initial force is required for the chain when falling from a flat surface so that the chain starts moving upwards and then down rather than horizontally and then down .

this is just easy, the pulling force created by the chain going down is making this happen, there is no surface force or whatever steve says, sorry steve. its the momentum as mehdi says. so when the end of chain hits the ground, the speed changes to constant because only a part of the chain is pulling down, until it hits the grond, and when it hits the ground it cant pull anymore. you can see that the more u pull the chain down the higher the waterfall will get. u dont have to do any videos. mehdi is the winner(they both deserve credit tbh)

Idk what to say. This is such a simple problem. It's the Centrifugal force that's doing a lot of the weird magic in these weighted rope/chains. It also increases till it balances out with the constant gravitational force, stopping the chain's acceleration. Now, like Mehdi said, he is an electrical engineer so, I think its fine that he didn't arrive at the conclusion straight away (although, his explanation is the closest to the correct mechanism), the other ppl from CAMBRIDGE have no excuses!!

So it seems to me that gravity just happens to be the force that is pulling on the chain. The part that makes this look confusing is the chain it self. When the chain reaction starts, part of the chain is static and the other is loading inertia and transferring it to the next link in line. Like if you tied a long rope to a car and on the other end attached something like a brick and you drove the car at high speed, when the rope is fully extended the brick will experience all the available inertia from the fast moving car at once and it will have to move in the same direction as the car. first changing direction which is effectively a whipping effect. Back to the chain, as the chain lengths down wards it has more potential energy then the static links that are at the beginning of the curve. So the links build them self upwards at a faster rate then the part of the chain that is straight down. the part of chain that is going straight down is also experiencing constant tugging tension in both way, up and down thus feeding the rising or growing fountain curve.There are other minor forces at play, but i think in my humble opinion this is what is happening. ElectroBoom I love your channel. You definitely make learning fun. I appreciate your efforts.

These Cambridge guys are way off the mark. The "kickback force" they are seeing is just the normal force that appears in any free body diagram of an object in contact with another object due to gravity. It is balanced by the gravitational force. It is the chain tension force that provides the unbalanced accelerating force.

First, it’s “between X and me,” not “between X and I.” Second, it’s “better than I,” not “better than me.” We can scarcely apply the rules of science logically if we cannot apply the rules of English usage. Now, this argument is very simple. Mould is clearly wrong. This can be settled very simply by having the free length of chain (the length of chain being pulled up) hang freely under the force of gravity, and not resting of any kind of horizontal surface that could be argued to give it a “kick up force.” The argument is risible on its face. You can’t push on a string. This experiment would require working from a substantial height, simply to provide room for the hanging length, but a balcony 2 or 3 stories up should suffice. In addition, the free length might have to hang with some substantial radial clearance within a guide tube, just to keep it from going pear shaped. But it might not. Easy to try either way. Support the free end of the chain (then end to be dropped) over a freely spinning light weight pulley to start, just to give it support so the delicate chain won’t have to drag over the edge of the tube and perhaps break. Attach a weight to the free end of the chain that weighs significantly more than the free hanging, tube encased length of the chain, so that it will fall as desired. Then, drop the weight. After sufficient kinetic energy is achieved, the arc of the chain will rise up and away from the pulley, which could even be removed. It will rise higher with additional speed of the fall. The sideways banging of the free hanging length of the chain within the vertical tube can not possibly have a components force 90 degrees up and along the chain. There is no kick up force. No part of the chain is engaging any horizontal surface. Case closed. This might also not need the guide tube. The fact that this would work with rope or string as well merely reinforces the point. All real world elongated and flexible materials have some stiffness and so will arc around the bend when whipped. Like a fly rod and line.

I see the value of this argument, but after seeing both videos, I have to agree with Mould. most of the science in this is sound, but Newton's equal and opposite forces do not both act on the same object (The chain), but rather, they are the forces that objects exert on each other, so the inverse force of gravity would be provided by air resistance and the ground once it hit, but this would not cause the chain to become a fountain. (If I'm incorrect in an assumption or have a simple mistake, feel free to point it out.)
Tirdad Kiafar
Tirdad Kiafar Acum 17 Zile
The way I see it with my college level physics the friction does not play a big role, specially air resistance cuz these are really heavy for that sake (visual evidence from the videos) , but your point of hitting the ground and quick propagation of force is a good point. Unless you have a really friction heavy, resistant system like the latent in this video. To add to it I see the diameter of the chain on top stays the same if not hit the ground early, which was one of the Steve's main points (indirectly) so that is why a lot of people are trying to approach it from the centrifugal force stance and equations but I also can't see how that relates since it has a lot more forces in and out on the chain before and after the effective "circle" of centrifuge. I am totally at loss :D

I think that Steve needs to reproduce the chain fountain with the more flexible ball chain the exact same way as the original. Doing it in a different way (the way that he has) it feels like he's hiding something. Whether or not he is. For control purposes he needs to do that from the same beaker not laid out flat. The same test under the same circumstances. Otherwise it's missing a data point.

I have a suggestion on how to settle this debate at the end of this comment. So, I'm a HGV driver and HGV driving instructor and have to deal with momentum all the time in controlling the vehicle. I'm 100% on the side of Mr Boom here and I believe Mr Mould and the people at Cambridge are incorrect. At one point Mr Mould made a comment that you could get the chain to turn in a very small loop as momentum is something that isn't affecting the chain at all here. But if you look at the 5th gear vid of a ford focus being introduced to at solid block at 120mph momentum is never something that can be ignored You may say, "but it's not turning, it's just crashing!" and you would be correct, but imagine trying to turn that car at that speed on a hairpin bend. I wouldn't recommend being in the car at the same time. Mr Mould's videos also actually disproved what he was saying as on a few occasions the chains that supposedly didn't have the affect at times weren't touching the lip of the glass jar. Finally my suggestion to settle the debate. If to get the 'Mould effect' to get the chain fountain to start requires momentum it is essential that the chain has to rise before it starts to fall. Therefore it needs to start in a jar requiring the chain to rise before it starts to fall. However if the affect is created by a kick back effect as suggested by Mr Mould and the people at Cambridge, it should not require the chain to rise before it starts to fall to create the effect. So, start with your chain, not in a jar, but on a table, and drop the chain off an edge at the same level as the starting point for the chain. If the kick back theory is correct you should still get a fountain. If the momentum effect is correct you wont. Personally I believe you'll still see the momentum effect as the landing point for the chain will extend beyond the very edge of the table up to the point the momentum of the chain moving across the table has been neutralised by gravity.

The spaced floor trick doesn't actually rise up and above the start point like on the floor. If you put a mark on the floor it should move up past the mark on the floor like how the bead chain comes out past the lip and grow higher even tho it comes out deeper from the container. If the floor tricked work it should move up past the mark on the floor and continue to move towards the right of the screan. So in my opinion none of the "spaced floor* techniques showed here actually demonstrated the effect. It seems to only occur when dropped from hight and forces of gravity are applied to the chain.

Neither of you mention the fact there is a clear twisting action to the mould effect, the chain doesn't just move up, it rolls/corkscrews up. I see the top of the chain in motion as a wheel with torque, for some reason this is traveling back up the chain as a twisting force, does it always curl the same way? the chain links can also act as levers in a twisting motion they are much less flexible that way, its another source of force. What's the ball chain core like, is it one continuous cord that also resists/transmits twisting much more efficiently than traveling around? What about whips, I feel like there loads of maths around whips breaking the sound barrier and it seems like a very similar motion?
