This Weird Shape Rolls Uphill Instead of Down 

-Bro where are you? -Up here on the tree -How did you get up there? -I fell.

This glitch will be fixed on the next update .. If you find any more glitches.. Just report or update your simulation.. Thank you.

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

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".

Did you roll up hill? Cone: yesn’t

0:51 *“now watch both of theses at the same time now”* My eyes: 👁 👃 👁

Interesting video! I understand how it works. Thanks for sharing this with us 😀

Now I understand Lil Wayne when he said I fell from the streets, I landed in the sky. 💆

When life starts going down, be this cone not the cylinder.

"Gravity HATES this shape. See how it gets 54 inches of uphill per week using this one simple trick"

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.

this is the first one i actually understood before getting it explained to me

_Your free trial of gravity has ended._

_"Oh no! I've fallen, and I can't get down!"_

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.

Stayed for the explanation!! Loved it 🤗 thank you!!

Me: I just want her to fall for me Her:

Schrodinger's Cone: Falls up and down at the same time lol

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

Well explained 😊

There's got to be a hamster in there

Disclaimer: no laws of physics were harmed in the making of this video

0:43 If you look at the center cylinder, you’ll notice it actually descends as it rolls up the ramp.

Despite appearances, the cunningly shaped rotating body still goes downhill, you just have to pay close attention. A playful method, it also sheds light on the essential background of physics. Super.

task manager: unfortunately, gravity has stopped working

Although it rolls upwards, its effective center of gravity is going down. The shape sinks into the ramp due to its V shape.

I'm very great full for your videos and explanation 🙏🏻

This video reminds me of the Oregon vortex where everything just rolls uphill and gravity is just broken😂

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.

Me: He’s probably got the table slanted The Action Lab: To show you that the table isn’t slanted..

Very well explained. Good demo.

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.

"why are you crying?" "sniffle i fell up the stairs"

“What if I switch them?” *creates black hole*

Great video. Love the explanation!

The Vampire from Blade needed that under his shoes. 😂😂😂😂😂😂😂😂😂😂😂😂

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.

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.

Great stuff...thank you Sir...👍👍

Really cool video dude good job!

Plot Twist: That weird shape is from Australia

science class: *has a test tomorrow i havent studied for* me, an intellectual: *watches the action lab to study*

Reminds me of the game I played in my youth called "Hit the Spot." I think of the hundreds of times I played, I finally got my muscle memory to where I could win one out of 10 times. Tough game!

Thanks for the inspiration

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.

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

very smart explanation! congratulations!

I wish I could be so fascinated by such simple and mundane things. It looks like he's having fun.

This is what weed smokers mean when they say *Roll Up*

"hey everybody so today we are going to cheat the laws of physics into making something roll uphill"

If you check the center of the object it is going downhill. The spread of the runners allows it to fall and appears to go uphill but the object is going down.

Same principle used in CVT pulley for matic motorbike.

the ramp: "Never gonna let you dooown!"

I want a video collage of all the times he said something like "why is this happening" and similar, I think it would be great reaction material

Helium balloon in vacuum chamber: Let me do it for you

2:11 "..roll uphill, or basically fall up" I just watch my cousin trying to go up the stairs. She does a 'very' good job falling up the stairs 🤣

Alex: "You made me proud that day." David: "I- I- I fell." Alex: "Yeah. But you got back up." *end credits roll with the main theme playing*

What in the world of magic is this! This is real magic!

this guy is just crazy. im learning too much

That wooden object sinks into the opening therefore making it actually roll down instead of up.

Now I'm trying to think of ways to implement this into my work environment lol. (pipe yard)

Sir, if you mind to answer my simple question I WILL BE GRATEFUL. What was your "course" when you're in college to study those things you've learned? Engineering? What kind? Mechanical? Scientists? I like to study as you did if I will have a chance. Glad you explained it, it's amazing content, thank you so much!

Indeed you are a Physic-cian. Happy to watch your clips.

Don't worry guys Schrondinger's Cone is just having a rebellious phase

The physics teacher: The test isn’t that hard. The test:

that was interesting i learned something new today

Would be interesting to see this applied in Roman times over long distances. Carry it to position, fill the hollowed interior center, roll.

When I read the title I said in my head : “I need this shape on my bike!”

Further Explanation: The shape of the ramp (like

this would make a very interesting perpetual motion machine. perhaps even with useful aspects.

The cone shape is important, but the weight of the item is also a key to this working and the triangular shape of the track.

"Hey everybody, today we're going to be clipping out of bounds and into the backrooms."

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.

These videos always amaze me

“Dr bright is no longer allowed to make 3D physical shapes that defy known laws of physics”

Me: so does it fall down? The Action Lab: *WELL, YES BUT ACTUALLY NO*

i learn more from this channel than i do from school

I automatically knew what it was, but it’s still really cool to look at

Instructions not clear enough: broke my legs falling up seven flights of stairs

3:15 _The vacuum chamber made my anxiety chamber expand aswell_

Initially, my first thought was wondering if this could be used for perpetual motion.

😮😮😮Question. If you took this wedge roller and at the fat end of the wedge track, the wedge roller drops into another wedge track at it narrow point and will it continue on? I.E. The inertia trusts the wedge roller onto the next track. 🎉?

Newton: discovers gravity Wierd shape: ...and I took that personally

rolling that glass beaker gave me anxiety.

The shape that you used (the segment that ends at 1:42) is a cone, meaning it will widen before moving down the ramp.

It moves uphill because the invisible fairies are pushing it.

Universe: gravity This cone: let’s pretend I didn’t see that

Other shapes to Cone: "WHAT IS WRONG WITH YOU?"

WOW. This is great. I think I'll try to make one and use it in a session of youth service at church and incorporate it with a Bible story. THANK YOU

Makes me think techniques such as these were used in more primitive times of construction. The great pyramids and such.

" *Watchu know about rolling down in the deep* " Weird shape roll: *No*

Using the glass as the downward cylinder gave me massive anxiety 😂😂😂

So, the incline is not sufficient to counteract the rate at which the two guides widen, therefore the positional energy moves it up the incline. Cool stuff

This could be the solution for Sissifus problem, make a Rock that runs upper hill by it self

Gravity: "I need to make this thing fall to the ground...... *Notices an angled, upward slope* ......Perfect."

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. RU-vid have finally caught up. 😆

That illusion has been around for 100 years bro.

0:35 C'mon Man 🤣😂 I know many are that dumb. good one

"hello everyone this is YOUR daily dose of internet"

Imagine showing this to Isaac Newton Edit: It's just a joke, have fun and move on, don't kill me
