It seems you could have a domino system which could stand back up by itself (except for the last piece obviously) only using the starting kick energy, it just seems like a ton of very fiddly work and could be achieved by having a moving weight inside the piece so when toppled the CoM changes to be above the balancing notch being able to kick back enough energy to the previous piece while being able to kick over the next one. Although I believe there would be some very strict limitations on how many pieces you could line up due to the amount of energy lost between pieces, also the magnitude of the initial kick should be standardized so you can calculate appropriately how to alter the design of the pieces. As said before not impossible, just really finnicky fiddly work.

Yeah, IMHO criteria for the impossible domino would be: * All dominoes are equal * All dominoes get back upright at the end of the process * Must be able to work at any size (theoretically), so given just one model of dominoes i should be and to make this work with 10, 100, 1000 etc pieces. I shouldn't have to modify the model depending on how many must fall

TL DR: The second domino is designed to give some of the kinetic energy is has to the first domino when it hits the ground. The hollow top and bottom is not really important, it just makes the second domino store more potential energy than the first, despite being the same material, so it takes less energy to upright the first domino.

I thought so too, but I don't think that would work too well. The only potential energy in that system would be the initial push you provide. Each domino resists falling over so a lot of that initial energy would be wasted through friction and there wouldn't be enough left to make the next domino fall over after a couple in a row.

James, Here's something I noticed at 1:29. The domino with the big hole through it has its long sides acting much like springboards. When it hits the other domino (on the left of the screen) the impact lands around 2/3 down from the top of the long hole (visually), compresses the 'wall' of the domino on the right and springs it backwards. That in my opinion is the momentum which caused it to flip the other way. Hope at least some of this makes any sort of sense :)

The issue is that you can’t really chain this together because the domino kicks up the one behind it with a leveling action, which won’t happen if it falls onto another domino. But technically if the last domino had enough potential energy it could kick the one behind it up and cause a chain reaction to the end of the line.

@nickryan3417

This *entirely*. The tipping point energy break point is only about knocking the domino down, the setup energy is the energy delivered after going through this point. For the first domino to be put back up the energy imparted in it must exceed the energy difference between the potential energy of it falling over. This was delivered through the kick back of the first energy pivoting on the rib that was on its far side. The description of the physics in this video was right in the description of the falling over and the tipping point, but wrong in the description of the domino being setup again. There was more potential energy in the second domino through the weight position and this when imparted to the first domino provided the energy to right the first. That's it, nothing more. It would be more interesting to see this managed with multiple dominoes rather than just one, however then it the energy loss (inefficiency) of the process would start to become very obvious.

Weebles, wobble, but they don’t fall down... 👍

I thing this is possible if the center of gravity is at the bottom like the toys that have a spherical base and heavy bottoms. Now imagine this with miniature versions stacked next to each other like dominos, when the first one is pushed it pushes the other one and so on and each one comes back to its initial position. But the distance must be accurate or else it might topple the one behind it.

This also works because you dont have to push it all the way straight, as, if the weight passes a point on which it is farther on the side its falling to from the corner its passing, it will always return straight, but if it doesnt pass that point, no matter what you do, it will always go the other way

This reminded me a toy I used to play called "hacıyatmaz" It is a toy that no matter what position you place it, it always stands back up because of the weight in the bottom of it.

Since you're making the hit domino asymmetrical, might as well make the side that gets hit square at the bottom so it can transfer more energy back into the first domino, possibly enough to use the geomtetry of the hole alone to get a balance without any added weight

Unbiased product recommendation: I have used the very same scale (2:27) to measure "other things" to milligram precision hundreds of times. It's a great scale, I'd _highly_ recommend it.

This video was uploaded before mark Rober's video and mark rober was working on the dominator for 2 years so the conclusion is that, coincidence

1:04 When you feel super bored

Yes, but what the trick is... is to sustain a "kick back" reaction for a series of dominoes. Not just one. That is a matter of engineering and balance for each domino. I see a flange at each base which exaggerates the Kick Back reaction (of the domino behind it) and still allows the higher center of gravity to smooth out the tipping point. The flang also provides an arresting point of the kickback reaction, so you can put even more energy into the kick back than needed.

Weighting the bottom of the first domino actually raises the activation energy for tipping it, making it less likely to tip back the other way. It probably doesn’t do very much to the potential energy, since that was already sufficient to make the other domino kick back.

I’ll bet if you put a bunch of the “A” style dominos in a row with the “kicker” style domino at the end, it just might kick a few of the “A” style dominos back up.

If the weight on the bottom was dense enough(think a lead plate as a base) it could always return to upright because it would take more energy to knock it over than to go back upright. An extra strong push would be required which would lose energy to heat. In theory you could get a handful of these dominos in a row to all bounce back up, but the initial push needed would get higher per domino. Like a strong flick for 2 or 3, approaching like a rubber ball fired out of a cannon for longer chains. It would be interesting to make that. But it would require extreme density on the bottom, with a slightly curved base I think so that the lead plate could never reach metastability. Definitely a cool idea to get like 4 or 5 lead weighted reverse dominos in a row. Might hurt your hand flicking it hard enough to knock the whole row over.

I think you should have also included some discussion that the bottom weighted domino bounces back up because you designed it like a tuning fork, the kinetic energy of the falling Domino gets stored in the lower prong of the domino that as potential energy stored in the spring of the Domino which then pushes it back up as it releases.

Yes, but the momentum will be loss over the course of the line.

Short answer: no Long answer: you need a custom 3d printed domino and a bit of weight.

Oh, you are an amazing man, I am sure you have the potential to change the world of energy production, you are so close, please keep going and please keep sharing your insights. I have to say I dont care how you gather or glean this information what you do is truly revolutionary.

Could you set up the second domino to knock over two more like the first? Maybe put a tiny bar on each side to start the next two dominoes. Repeat the pattern and you can get a chain reaction, but not in a straight line

I just spent 15 minutes of my life listening to a guy talk about his struggles getting it up. Science

you watched it three times ?

What if you remove the added weight on the bottom of the "A" style domino (so that it tips over in the other direction like here 1:26) but put a second "kicker" style domino on the other side? It should fall and be kicked a second time, right? By fine-tuning the scale and/or center of mass of the second "kicker" there must be a way to raise it up again clean! That would be awesome to watch!

It was the levering motion of the second object (at the end of its fall) that pushed the first object back. The first's own rebound wasn't quite enough to pop it up, so you'd have to time making the third object fall somehow (external force, i.e. a second manual push) to get it to bounce the first sufficiently, basically doing the same thing once per side. Big no-no if you're using the word, "dominoes." This experiment started out so far from dominoes, (as far as the shapes presented in the video) that I think taking it further into more unique shapes doesn't really get closer to either useful physics or game experimentation. It's basically _only_ doing the second half of a Mythbusters experiment: Make it work, no matter how absurd the input needs to be. While the resulting explosions and other silliness were _always_ fun, the interesting _science_ always happened in testing the original idea. Some of the comments about Weeble-like devices might lead to an interesting physics/sound toy, and would at least allow all parts to be the same shape, which is somewhat common with dominoes, which are usually the same basic shape. They would also do what more people expected: All tip back up, not just one.

This channel really brings me back to the day when I used to watch "Mr Wizzard" on TV as a kid, great stuff. =]

They don't necessarily have to have different potential energy. The first domino could bounce off the second, keeping most of its kinetic energy and only needing a smaller push. Or it could hit the second domino while still most of the way upright, where the second domino has to fall all the way over to bring the first one back up.

Was I the only one waiting for an Impossible domino chain!?

A third Domino would block the kickback effect, so this isn't really Dominos IMO.

Agreed. This won't be sustainable unless dominos get bigger with each step.

I don't think it would work even then, because the effect in this video requires each domino to land all the way flat, which would be ruined by the dominoes propped up by its neighbor. Further, once the final domino does lay flat on the ground, that kickback effect can only be applied to the 2nd to last domino, which it may not even be able to do due to the domino before it resting on top of it. Cool demonstration and explanation, but were no longer talking about dominoes anymore

exactly... we are not talking about dominos anymore. 😊

Now I'm curious, if you made many ones with different weight distributions, could you make a chain where knocking over the middle one causes that half to fall, then flip in the other direction. Then the chain oscillates just with one more on each end staying down. The extra one staying down on each side would be releasing the energy to maintain it. I assume every domino would need to be unique and placed in a very specific order to work.

It is kind of intuitive but what a clear and concise way to explain what is happening with so much context. I wish you had done more film shots at even faster speeds of the domino effect at 1:27

In my physics class we are learning about these energies!

If he used even a string of 3, this would not have worked, because the second domino is kicking the first one back up

In theory could you keep changing the mass and center of gravity slightly to keep knocking over and setting up the domino behind it? Like a self setting domino line?

You could use the bounce back of the first domino to start pushing dominoes on the other side also, like a pendulum swinging from side to side

4:48 doesn't the second domino have kinetic energy at this point?

@ingcarmine

2 жыл бұрын

Yeah, all the potencial energy is converted in kinetic energy right in that point, and that kinetic energy is enough to push back up the lighter domino, since it needs less energy to get straight again.

I enjoyed your experiment Thank you brother 😊

Maybe my attention switched at some point, but I didn't hear an explanation about that ridge on the solid domino. It makes a class one lever and maybe that is why it transfers so much energy back in the form of a kick.

The Impossible Domino is getting a pizza from Domino's that doesnt has less toppings

not spreading hate or anything but wasn't it obvious that if you would increase the weight at the bottom it will come back, you know like those dolls which have a rounded and heavy bottom. just round the domino bottom a little and add some weight to it,

It may seem obvious to you but it can be nice to have an in depth explanation for a lot of people (such as myself)

Really cool concept! I wonder how perfect it'd have to be to have a line of dominoes that does that. The two you use are different weights, but the one that pops back up weighs more, which means I think it'd be possible to have a line of them that weight the perfect weight.

@imanuelc143

Hmmm, you

In principle you can make a chain of these, provided the total initial potential energy of the dominos that doesn't get up again is larger than the total inital energy of those that do.

Yeah, I’m always disappointed when things fall and don’t magically go back to their starting point… WTF?!

"no matter what, it can never get back to the height it started from" What if you pick it back up? Obviously this is supposed to be a joke but I decided to put this here because honestly this is not a very good joke

Only energy from dominos count 😉

Seems to me the first domino being knocked down has more to so with it's shape than where the weights is at, meaning if you have the right 'shape' of the domino to kick up the following domino regardless of the weight of the first one or the positioning of the weight. TRY IT. You can see it in the video the shape of the first one is what helps kick the other one more so than the weight positioning itself, hence questioning if you need the weights there to begin with.

You're a creative genius, great content!

Theory: thin out one side of the long hollow one to increase its CoI (coefficient of restitution... think golf club or tennis racquet) Also add one of those lips to every tile. May need to be placed lower on the tile to compensate for the lower cog 🤔

Wow! This explains the bead ball dealing chain effect or so called mould effect

You should put a solid domino on each side of hollow one and see if you can get the middle one to knock down one side, pop back up and hit the other side and stop sitting up in its original position.

That's a really amazing thing to see that pop back up I've an idea that you can create a domino chain that pop backs up. Based on your concepts you can make individual pieces such that their centre of mass gets to more height successively and with the right centre of mass and weight you can make them such that every individual piece has sufficient energy to drop the front piece it every piece which falls have sufficient energy to pop the previous piece back up. You might use different materials to print different pieces if any problem arise I don't know if its exactly possible or not but it would be fun to research that. It would surely need very much calculation and experiments to see if it actually works out or not. I would also love to do this experiment but I don't have the required instruments such as a 3d printer. So my only hope is you now 🥺

Movable weight inside the dominoes with guided paths enables them to get back up fixed amount of times.

You could put another domino on the other side. Push the middle one to the left and falls left then is kicked back up with just enough energy to make it stand up and fall to the right and then kicked up straight again. Would require a lot of finesse but should work. Right?

Now you should make a whole bunch of them with both weights and lever-notches to see how many you can push and self-right until the extra energy from the pushing is used up. Good luck!

id say bcs it only needs to have the cen ter of mass in between the parts tthat tought the floor, so it actually needs a bit less energy
