It's easy to fall into top of the tree. All you need is some flying device like helicopter, plane or whatever and jump or accidentally fall through open door or something.
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".
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… 🙃
Thank you. in 6minutes and 20 seconds he spent 20 seconds talking about the wooden thing, and never explained it. You summed it up in a single sentence.
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.
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...
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
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: ua-cam.com/video/o4xTbyfQgps/v-deo.html 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.
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
Same with the styrofoam. It has a thicker side uphill whose mass imparts a great force via gravity toward the “uphill” side than the light side toward to the downhill side.
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.
Yeah due to widening of rail the massive portion of the double cone is sinking so actually its centre of mass is getting down but our eye the judge the level of edge of cone
EDIT: - OHHHHHHH NEVERMIND I GET IT.... but yeah, STILL witchcraft, LOL. - Wait so if there wasn’t a divot for the thing to roll up into, would this still work? I’m so confused. Y’all are witches. Lol
Ironic thing is, is that this is exactly gravity working as its pushing the back to back cone down which means that in turn it causes the shape to roll uphill as to get lower down it needs to move to the part where the pieces of wood ar further apart
I feel bamboozled!lol Like the way I felt when I learned that Reno is actually further West than Los Angeles! I have traveled from Los Angeles to Reno multiple times, and I always go East.
It's center of mass is still technically moving downwards, so the energy for the movement yet again comes from the objects gravitational potential energy.
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.
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.

It widens faster than it slopes, and the wedge shaped object rolls into the gap. Its a cool effect and makes you think. A lot of demonstrations use a similar ramp, but this time it makes all the difference.
@@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.
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.
The explanation should have mentioned that the widening of the two inclined sides let the CG of the cone sink as it rolls up the incline, due to the V shape of the cone's middle. Nonetheless, it was a really good and entertaining video as usual from The Action Lab.
Could this be turned into a perpetual motion machine if it drops into parallel sides at the top and gets guided back and connected to the v shape again?
@rxot: Precisely! That's the crux of the physics behind the entire video and it isn't even mentioned! I was reading the comments wondering why in the hell no one mentioned that!? WTF?
True if you look at the centermass of the wooden object from the side then its actually going down because the diameter gets smaller and some otherstuff thats hard to explain but you get the point

@brutally_honest How about a weight attached to the inside of a pipe, then you could make it roll uphill like the foam ring, but only for half a turn of course, You could really freak people out by making a motorised weight so it runs continuously, you could use the motor and battery as the weight, a remote controlled version so you could start it rolling as your colleagues walk past would be the icing on the cake 🤣 Happy building!
I first noticed that the cylinder didn't roll true, which meant that the sides were not at the same level, which meant there was something funky going on with the shape of the ramp, that said I didn't catch the center of mass issue until the end, so good job on that trick.
Theres this place in the UK called 'the crooked house', its a pub, which slants to one side. Weirdly this experiment works there too. People use a coin there and it rolls up instead of down
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.
NASA used this principle in the design of the Apollo Command Module. The CM's center of gravity was off set so that on re-entry into the atmosphere, when the CM was rotated, it created lift and this allowed the landing point to be adjusted during the re-entry free fall, if the controllers on the ground found that the CM was landing either short or long, the CM could be rotated to adjust the length of the fall so it would ultimately land in within the desired "footprint". This is why, during the early space flights of Mercury, which didn't have this lift factor, the capsule often splashed down many miles from the recovery ship but during Gemini (which did have the lift factor) and Apollo, they almost always landed within sight of the recovery ships. During re-entry the CM didn't just fall in a perfect arc. It fell, went up again like a roller coaster, then resumed it's fall. This not only made landings more accurate but also by stretching out the arc of fall dissipated energy and the friction heat created by the fall through the atmosphere.

My grandparents had a toy/game/puzzle from the 1950's or so that was basically this: a large ball bearing (about the size of a golf ball), with 2 metal rods in a wooden frame. you could move the rods and try to balance the ball bearing on them, changing the angle at which they were touching, to get it to roll uphill. The game was to try and get it as far as possible up the rods - there were little buckets beneath it, and you would get points based on how far you could get it up.
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. UA-cam have finally caught up. 😆
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.
@@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.
@@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.
Yeah, the triangle shape of the platform causes it to create momentum in the opposite direction, rolling up. It’s easier to understand once you see it for sure
Check the axes the cone is rolling on, as it goes up the slope, did you notice it's axes is still going down? On that note it's still technically going down as it sinks faster than it's traveling up the slope.
He didn't really explain how the ramp works, the trick is in the V shape of the ramp and the cone shape of the roller. At the lower portion of the ramp the roller sits higher up, but as the rails get farther apart the cone gradually sits lower on the rails, it it is actually "getting lower" as it "rolls upwards" as long as the ramp isn't too steep
@@BrunisPistol Yeah, I found the explanation part to be rather lacking in this one. I'm fairly certain I get what he was saying, but I feel that a little extra clarification would have really hammered this one home. He usually does really well at this, but I found this video's attempt to be a bit o a fumble. Oh well. Can't win 'em all, I guess. :)
gravity is actually the reason this object moves upwards, the weight of the center pulls it down, but due to the shape of the hill, the weight moves outwards as the platform grows more open, and that's why that shape moves up the slope.
@@unprovengravity Gravity has a force of 9.8 m/s/s, so with this force pulling on it, it makes the object roll fowards, and fowards in this situation was up. Or at least that's what my theory is. Could be wrong but that's what I believe is happening.
At the place where I worked we had this in a big version made out of metal, we had a lot of cool (interactive) science exhibits and we would teach people about them and guide them through (that was the job)
Here's additional explanation on how I assume it works in addition to the explanations below: because the object is a double cone shape, as it rolls up, the point holding it on the track is a smaller and smaller radius. As the radius decreases, that's what is lowering the mass of the middle, because instead being held an inch or so above the table at the middle it it being held at the points and dropping the center. If the rods were parallel, it would never change its holding point.
@@romanieoo the shape of the object allows it to roll uphill because the slope of its sides are greater than that of the hill. The v shape of the track and shape makes the center of gravity go up if it goes downhill, watch the center dowels elevation
As soon as I saw the wood piece triangle thingy, I knew exactly what was going on, how other people don’t get this concept confuses me. I’m only 17 and I have made so many things from hand, and even moved heavy objects in this manner
@@WYIT0 I mean he could have used something else to get high. Just probably not the graduated cylinder. (I can think of a few ways to use one for that anyway.)
@@fluffycritter a bong is just a cylinder that never applied itself, but if it enrolls in a 4 year collegiate program and focuses on its studies, it too could one day be a graduated cylinder.
The weight is in the center. So the tendency for the conical core to "fall" into the wider part of the track is greater than the tendency to roll down on such a slight angle. Give it straight tracks or a steeper angle and it'll roll down like normal.
@@AnotherDaveInTheLife I wouldn't say it's a bad video, he explained exactly why this phenomenon happens. Marvin seems to be confused, the result of the tendencies he is talking about is the path in space that the center of gravity of the cone is taking. That cannot go up on its own, only down. In the examples shown when the cone moves there is a horizontal translation accompanied with a vertical translation of the center of gravity, always downwards. If you look at it from the side this can be simplified by looking at the center axis of the cone which will always move down if it starts rolling.
@@shiro-r4m What are u trying to say the center of mass moves down always?? Or in the example the m.g.sinx < the reactive force of the base railing Reactive force = m.g.sina.sinb a,b are angle of cone and base x is the angle of slope of railings *Disclaimer* : Maths may be wrong pls *do verify* before assuming my values to be correct
@@shreyasdas5130 you are overcomplicating it I think. This phenomenon works with a cone angle greater than 0° and smaller than 180°. The angle between the rails can also be from greater than 0° to just under 180°. Every combination of those two angles results in a forward and simultaneous downward move. If the center of mass does not go down, there is no forward speed to be gained from gravity
That or maybe he had just watched that movie Upside Down, the one with two planets connected by a giant tower. The gravity reverses halfway up the tower.

It widens faster than it slopes, and the wedge shaped object rolls into the gap. Its a cool effect and makes you think. A lot of demonstrations use a similar ramp, but this time it makes all the difference.
Yes. That's joke from 500 year B.C. and also just centre of mass is high
@@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.
@@coleh46 / The dude doesn't even talk about that.
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.
_L + Ratio_
The explanation should have mentioned that the widening of the two inclined sides let the CG of the cone sink as it rolls up the incline, due to the V shape of the cone's middle. Nonetheless, it was a really good and entertaining video as usual from The Action Lab.
Could this be turned into a perpetual motion machine if it drops into parallel sides at the top and gets guided back and connected to the v shape again?
@rxot: Precisely! That's the crux of the physics behind the entire video and it isn't even mentioned! I was reading the comments wondering why in the hell no one mentioned that!? WTF?

Some of the experiments these guys come up with are mind boggling
Theres this place in the UK called 'the crooked house', its a pub, which slants to one side. Weirdly this experiment works there too. People use a coin there and it rolls up instead of down
It's probably an illusion or something.
We have that here in the US at Landrums
One in the US in the upper peninsula of Michigan
@@noahcrawford2693 surely this cant be real
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.

@@SCP--un2jo I read this right as it ended
NASA used this principle in the design of the Apollo Command Module. The CM's center of gravity was off set so that on re-entry into the atmosphere, when the CM was rotated, it created lift and this allowed the landing point to be adjusted during the re-entry free fall, if the controllers on the ground found that the CM was landing either short or long, the CM could be rotated to adjust the length of the fall so it would ultimately land in within the desired "footprint".
This is why, during the early space flights of Mercury, which didn't have this lift factor, the capsule often splashed down many miles from the recovery ship but during Gemini (which did have the lift factor) and Apollo, they almost always landed within sight of the recovery ships. During re-entry the CM didn't just fall in a perfect arc. It fell, went up again like a roller coaster, then resumed it's fall. This not only made landings more accurate but also by stretching out the arc of fall dissipated energy and the friction heat created by the fall through the atmosphere.

My grandparents had a toy/game/puzzle from the 1950's or so that was basically this: a large ball bearing (about the size of a golf ball), with 2 metal rods in a wooden frame. you could move the rods and try to balance the ball bearing on them, changing the angle at which they were touching, to get it to roll uphill. The game was to try and get it as far as possible up the rods - there were little buckets beneath it, and you would get points based on how far you could get it up.

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. UA-cam have finally caught up. 😆
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.
@@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.
@@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.

Check the axes the cone is rolling on, as it goes up the slope, did you notice it's axes is still going down? On that note it's still technically going down as it sinks faster than it's traveling up the slope.
I'd also direct them to the waterfall that falls up.
The shape: *Rolls up*
Me: wat
The Action Lab: *Explains*

He didn't really explain how the ramp works, the trick is in the V shape of the ramp and the cone shape of the roller. At the lower portion of the ramp the roller sits higher up, but as the rails get farther apart the cone gradually sits lower on the rails, it it is actually "getting lower" as it "rolls upwards" as long as the ramp isn't too steep
@@BrunisPistol Yeah, I found the explanation part to be rather lacking in this one.

gravity is actually the reason this object moves upwards, the weight of the center pulls it down, but due to the shape of the hill, the weight moves outwards as the platform grows more open, and that's why that shape moves up the slope.
Without you my brain would have died
@@unprovengravity Gravity has a force of 9.8 m/s/s, so with this force pulling on it, it makes the object roll fowards, and fowards in this situation was up. Or at least that's what my theory is. Could be wrong but that's what I believe is happening.
Still didn't get that 😐
That shape doesn't actually move UP the slope at all. It's an optical illusion.
@@0verloaded 9.8m/s^2 is not a force, but an acceleration. the force would be 9.8 n/kg
Stopped at 1:22. The shape makes it want to fall pushing it up because the it widens as it gets higher.
I was wrong
@@nydeity9100yuh
At the place where I worked we had this in a big version made out of metal, we had a lot of cool (interactive) science exhibits and we would teach people about them and guide them through (that was the job)
Here's additional explanation on how I assume it works in addition to the explanations below: because the object is a double cone shape, as it rolls up, the point holding it on the track is a smaller and smaller radius. As the radius decreases, that's what is lowering the mass of the middle, because instead being held an inch or so above the table at the middle it it being held at the points and dropping the center. If the rods were parallel, it would never change its holding point.
smort
what
@@romanieoo the shape of the object allows it to roll uphill because the slope of its sides are greater than that of the hill. The v shape of the track and shape makes the center of gravity go up if it goes downhill, watch the center dowels elevation

The rolling object is going down its more of an optical illusion
The weight is in the center. So the tendency for the conical core to "fall" into the wider part of the track is greater than the tendency to roll down on such a slight angle. Give it straight tracks or a steeper angle and it'll roll down like normal.
Exactly! Thank you. I don’t know why this guy puts out bad science videos.
@@AnotherDaveInTheLife I wouldn't say it's a bad video, he explained exactly why this phenomenon happens.
Marvin seems to be confused, the result of the tendencies he is talking about is the path in space that the center of gravity of the cone is taking. That cannot go up on its own, only down.
In the examples shown when the cone moves there is a horizontal translation accompanied with a vertical translation of the center of gravity, always downwards.
If you look at it from the side this can be simplified by looking at the center axis of the cone which will always move down if it starts rolling.
@@AnotherDaveInTheLife i know right?? If only the guy had explained this in the video...
@@shiro-r4m What are u trying to say the center of mass moves down always??

*Disclaimer* : Maths may be wrong pls *do verify* before assuming my values to be correct
@@shreyasdas5130 you are overcomplicating it I think. This phenomenon works with a cone angle greater than 0° and smaller than 180°.
The angle between the rails can also be from greater than 0° to just under 180°.
Every combination of those two angles results in a forward and simultaneous downward move.
If the center of mass does not go down, there is no forward speed to be gained from gravity
