    it’s cool how when the second domino falls, it turns into a lever with that extra ridge, and can just spring up the first domino again! really interesting concept and great explanation. dominoes that are bottom-heavy indeed are easier to stand up.

  • @thom1218
    @thom1218 3 ปีที่แล้ว +252

    People want to see a whole row of them doing that... only problem is: those two are different from each other in mass and center of gravity, so they're not even dominos at that point. How about set a bunch of those pairs up in sequence so that every other one will return back up?

      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

      @eleSDSU 2 ปีที่แล้ว +7

      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.

      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.

      There would have to be a limit to the number you could have in a row, otherwise you could make a loop of them that can go forever, which we know is impossible.
      I suspect that the second domino having a higher centre of gravity is critical. If it was the same as the first I don't think there would be enough energy for the first to knock over the second.

  • @cardinalhamneggs5253

    I really like how this works. Because physics, the domino won’t have enough energy to return to its stable upright state, but it doesn’t _have_ to because it’s designed specifically to have enough energy to reach an _unstable_ position where, once reached, it will automatically settle into its fully upright position due to its low center of gravity.

    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.

      How is such a smart guy, not able to figure this out. I figured it out from just the few seconds of footage. You can clearly see the second domino kicked the first domino back up. Which is why it’s bottom isn’t flat and straight. It has nothing to do with the first domino

  • @contagiousingenuityagency5273
    @contagiousingenuityagency5273 3 ปีที่แล้ว +7

    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 :)

      i guess i'm kinda confused what the point of metastability as a concept is, like it's basically a local minimum. like if I place a steel ball in a bowl on a table, that's metastable because the bowl contains it but the ground would be lower energy. if i put it on the ground that's also metastable, because it's not at the bottom of the marianas trench. and even there, what if someone dug a hole at the bottom of the marianas trench and put it there, that's even lower energy. The only way the ball could be in a truly stable state of least energy is if i drill down to the center of the earth and put it there, and that's only if i don't consider the sun, or the supermassive black hole at the center of our galaxy, or perhaps whatever black hole happens to be the largest in the observable universe. wtf?

      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.

    If you rounded the bottom of the domino and weighted it to balance in the upright position, it should always stand back up. If you lined them up, the tipping effect would travel as a wave through the line of dominos in both directions. If you added a lip to the back side of the domino, the wave would only travel in one direction. That would make for a very interesting display of wave dynamics....

      An example would be what if you threw a bouncy ball at the ground as hard as you could, at a surface at the same level as your feet. Because of the additional energy, the ball would go far beyond the starting height. Imagine that conversion with dominoes, it is valid because it refers to the same law that is affecting the dominoes.

    I came up with the idea, that you make heavier dominos with a weight inside the bottom of it. The direction of the row of dominos is important, because you shape the dominos like half an "U" and half a "L" should look like this (use a bit of imagination) LU "falling"-direction to the right. The amount of energy that is required to get them back up is on a minimum. The energy consumption of the push is much higher, but you can use your finger to push those heavier dominos harder.

    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!

    • @VoltisArt
      @VoltisArt 2 ปีที่แล้ว

      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.

    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.

    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.

    Also add one of those lips to every tile. May need to be placed lower on the tile to compensate for the lower cog
    🤔

    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!

    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.
