The Impossible Domino

Also worth of noting would be that at the beginning there was potential energy stored in 2 dominos, while at the end there was only one standing up. :)

looks very cool

Make each domino progressively less mass, they all stand back up.

Could you design a domino where each domino stands back, making a resetting domino chain?

I wish you could make the same thing but both dominoes have the same shape so you could make a circle with them and have perpetual motion (Which is impossible).

now puzzle out how to do 3

Чел переизобрёл неваляшку

those aren't dominos.

Square weebles

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.

The problem here is that he was lazy about it and designed 2 different objects, instead of putting in the work to figure out how to make 1 domino that uses principles from both. Not to mention the fact that he completely failed to mention the fact that the domino doesn't need enough energy on the return trip to get back to being upright. It only needs enough energy to get the center of gravity back past the fulcrum, and gravity will provide the rest. And, with enough iterations on the design, I am reasonably confident that this could be achieved.
And don't you dare tell me to do it myself. I don't have the resources to waste on such an ultimately pointless endeavor, and I'm not criticising him for doing it the lazy way. My only gripe is that he left some important points about how and why it works out, when words cost nothing but time and breath.

I like their pizza

Probably a stupid question but, What if you put the weight on the back of the top of the domino will it gain enough energy to go upside down?

Grams? Where are those sweet freedom units?

A man discovers centre of mass.

We might correct our name of the masonry trick, something like a, Squared-Domino-Effect, if you will.

this feels like it's possible to make both dominoes the same and then have a sequence of dominoes that all knock each other over and back up

You have disguised a lever as a domino and allowed it to transfer kinetic energy into the object falling on it.

Next step is to make 100 dominos that have each a lower center of mass, so that all of them can be kicked up in a single row

Ummm... Weeble wobbles?

Now are there dominos that can actually be put in a circle, and they all pop back up?

Toyota says: nothing is impossible
so make a complete domino row where all dominos stand up again 😄

So can u make a hole row that stands back up?

Vyjebanec, von nám to neukázal vole, zmrd.

Couls you chain this with progressively bigger diminos to bounce back up each of the previous dominos in the chain leaving only the last domino fallen?
Since the requirements were that the second domino had to have more potential energy than the first domino to pop the first domino back up.

I thought this was gonna be impossible dominoes (plural)

Weebals Wobble

I was expecting something more like those odd figurines or those really funky he punching bags that stand right back up when you punch them

Wobble toys for the win!

Come on only two dominoes? Lame

Before watching the video, is was wondering a domino with a kind of pop, like that half falling ball that rebounces in floor gaining a lot of kinect energy that makes it fly higher than it was before.

When domino falls, it activate the pop and it become in vertical position again. That was what i was expecting.

Awaiting a part 2 of this video with more dominoes in a row. Sorry, english is not my first language

could you make impossible dominoes with helium and make it reset like that

Are you saying Dominals?

Cant you just make them all bottom heavy. Like the blow up punching bags with water on the bottom for kids. The force of your finger will knock the dominoes over to start with. Then it would return to its original place after.

you can use a spring to get a ball back to it's old height

My first thought is, free energy? Because if a ring of dominoes can knock the next one down and stand back up, that's a system running on its own potential energy.
But I'm guessing that any domino striking another domino won't fall far or hard enough to bounce the prior one back to its up position.
Thermodynamics wins again.

I was thinking along the same lines in terms of an energy barrier, but my thinking was that you don't need as much as 100% of the expended energy to get the domino back up. You would need enough to get it very nearly back up, such that gravity did that last little bit of work returning it to a standing equilibrium - as other people have mentioned, a little like a weeble. Maybe with the right material and configuration such a thing could be achieved - though I'm not about to try it.

So here's a question, can we make long chains of self-righting dominos and build wires and logic gates from them if we lower energy loss enough?

What if you put the hollow at the bottom ones on the both sides of the one that's hollow at the top.
Would it flip forever? 😂

I don't know if anyone ever notice but it's the same idea with a balloon boxing buddy which always turn back up.

Oh, the two dominoes are different. You can't set up a ring of them that would keep going. I knew it couldn't be done because physics. Just wondered, if the domino popped back up what would specifically stop the ring from keeping going.

When cheating like that of course it can get up again, also the "dominos" is 2 different ones and you can still not do it with a whole row of them in a line...

I love the old episodes, they aren't trying to sell us anything. =)

I'm angry that he didn't make a whole line of these and test them out

When you push on the top you have an initial velocity (KE+PE), does that factor in?

I would like if you make a round chain of those dominoes
