I just googled the Crooked House pub (in Himley near Dudley) and there's a wiki page about it. It looks even more slanted than the leaning tower of Pisa but isn't as famous unfortunately. Due to careful placement of objects like tables and the angled windows and brickwork (due to subsidence) a number of optical illusions occur. e.g. a marble will *appear* to roll uphill. It's the not the same thing as this video, which shows a "trick" object (with a weight in it) that actually does roll uphill.

[@Incepter.]

That object that rolls up on a slanted hill has rejected the offer of the laws of physics while The Action Lab is testing with him.

If the sides of your ramp were parallel instead of converging to the downhill point, both shapes would roll downhill. The object shaped like two cones put together rolls in the direction that has its center of mass descending on the converging ramp, so its center of gravity is "rolling downhill".

[@Rockancrime]

There’s a great version of this experiment that has a shape that’s inverted to this - the narrowest point in the middle. If you angle the ramp so that the thin end is higher, it will similarly “fall up”. Your comment reminded me of that version from the science center I went to as a kid. And now work at. I should dig around in the basement and go find it… 🙃

[@kevincarson9201]

that triangular shaped base along with the slanted shape of the rolling object is why it rolls up. Physics won't let those two shapes interact in a way that lets it roll the other directions

[@Novaflare187]

Well yes and no, it is not that the shape won't let it roll downwards. Around 1:44 we can see that the entire object does roll downwards (towards the less elevated side) after the ramp was elevated enough. But the shape does create different paths of varying resistances (and amount of energy needed). So depending on the angle/elevation the ramp, the object's center of mass will move towards the path of least resistance regardless is that is upwards, downwards or staying at rest.

[@hydrocharis1]

As kids we made marble runs with horizontal wooden blocks wicb diverge as the marble runs downwards. This was easier in construction generally, although you did have to support the sides enough to prevent the marble from pushing the blocks outward.

[@KieranTully]

It took me a while to notice that the rails move apart, which is what allows the conical mass to fall right, as it rolls on narrower and narrower parts of the cone (which sit lower on the wider parts of the rail). Whereas the cylinder has constant circumference and can only roll down to the left.

[@hananezumi]

Thank you for your explanation because I was still so confused about why it was going up after watching over the video. I don't know why he talked about everything besides what should be the most relevant part...

[@fikriirshade1132]

thanks the video didnt really explain why this particular set of object behave that way

[@Mr.Jarfish]

isnt is more like the thing that rolls 'upward' has weight at the top when he places it so the momentum of the weight falling down is seemingly making it roll upward? just like with the stirofoam circle. still quite genius design the wooden thing must have in the balance of weight

[@KieranTully]

No, I think the cone has uniform density, unlike the styrofoam disc which is weighed down on one edge. The cone rolls right not because it's heavier on one side, but because the rails move apart, allowing the cone's centre of gravity to fall down as the diverging rails touch the narrower and thus "higher" extremities of the cone. This view might make it more obvious: kzbin.info/www/bejne/pWXbhZWvm7aaptU The slope of the cone against the rails is more than the slope of the rails against the ground. At some point the cone stops narrowing (i.e. stops lowering the CoG against the diverging rails), and that's why there's a notch in the rails, for the cylindrical ends of the cone to fall into.

[@SD-G]

Exactly... Figured it out in a few seconds

[@l.riggins1857]

I'm surprised he didn't follow through with a cursory explanation as to how the center of gravity is dropping due to the shape of the object and the widening rail path caused by the rail angle on the ramp. I noticed this immediately, however many, including younger viewers might not fully get it without explanation.

[@SamiDoustdar]

Exactly

[@Ginrummy33]

Yes, if those two rails had been parallel, then it would have rolled down like normal, It's the spreading angle that makes the big center part of the "ball" thingy get lower and do so faster than the steepness of the incline. He really didn't explain his current objects well.

[@matiasbliznac2141]

He didn't explain it fully I think so for anyone interested here's a more complete explanation: basically, the reason the cone falls upward is that it actually falls downward. The reason for that is that it actually starts at a higher position because of the shape of the slope. It has a hole in the middle which becomes narrower at the base of the slope, and when he places the cone at the base, because of the shape of the cone the center of mass ends up higher, and as it rolls, it ends up falling into the hole of the slope and the center of mass moves down. Basically, this trick wouldn't work were he to place the cone onto two parallel sticks which he leaned against something because the cone wouldn't be falling into a hole at the same time as it rolls upwards.

For those who don’t understand: The wedge shape is supplementary to the pin rolling upward. Notice that the wedge gets wider as the pin rolls upward. This causes the pin’s center of gravity to follow the side it chooses thanks to its shape. As the v gets wider. The grooves accommodate the shape of the pin. Think of a marble rolling in a slit that is shaped like a V. When the slit gets too narrow, the marble will stop. When the slit gets too wide, the marble will fall out. Which one is related to gravity? Yes, the fall. That is why the pin rolls upward. Excuse my lack of vocab

[@Lootsizimanition]

Yes. That's joke from 500 year B.C. and also just centre of mass is high

[@josephbolt6203]

​@@coleh46 the centre of mass going lower essentially means that the object used its gravitational potential energy for motion. Similar how a ball rolls down hill. But in this case the object is able to use its gravitational potential energy to move seemingly up the slope even though its actually getting pulled lower by gravity, but thr shape of the slope and the object creates rotation to the right. Its definitely a pretty weird one. And it all has to do with the shape of the object and the shape of the track. IF THE TRACK was parallel it would not move upwards.

[@jamespyacek2691]

@@coleh46 / The dude doesn't even talk about that.

[@PreservationEnthusiast]

Centre of mass is still moving down, and thus potential energy decreases, as the slope on the cone and distance between the tracks is greater per unit length than the longitudinal slope on the tracks. He didn't explain this properly. Switching to the balloons was not helpful.

When I was in school, about fifty years ago, I saw this demonstration and it was explained that the centre of gravity was getting lower. KZbin have finally caught up. 😆

[@TheVoitel]

Actually this isn’t even about the center of gravity, it’s the whole thing that actually goes downward. Basically this is just a trick that works by selecting the contact point in such a way that it goes downward in the opposite direction of the slope. Just replace the wedge by a groove with the same angle, and you’ll see that is actually goes down in the other direction.

[@whi2gan]

@@TheVoitel I get what you’re saying, but a MASSIVE portion of both of the experiments IS still actually to do with ‘centre of gravity’, because none of the experiments would work if ‘centre of gravity’ was not in the equations.

[@TheVoitel]

@@whi2gan Well, argumenting using potential, yes. But my point is that the center of mass argument is unnescessarily obscure. Basically this video is claiming that this is happening because the center of mass is falling for inexplicable reasons. And I’m saying that there is a very clear principle why that happens. Maybe I worded that badly, I’m sorry. English is not my first language, so sometimes I use the language in ways that do not work.

The center of mass is changing because of the contact point of the triangle that the cone is above to. It is not explained very well. As the triangle opens,because of the shape,the cone goes deeper and deeper traveling upwards.
