This Weird Shape Rolls Uphill Instead of Down

The world if Newton never invented gravity

Because the hole ate the bottom small its go up because the hole at the up is big

is very simple it only roll uphill if the way is wide and the edges fall

I want to replicate this.
Someone kindly give me the architectural plan.

Mindblow

spanish please 😔😔

HUH

That was not weird at all

this looks like a contraption inside an ancient temple with traps

Wobble..

It’s pretty obvious the slope of it falls into the angle of the boards. Still cool tho

Something weird happens? It would be weird if it would roll downhill.

The explanation for the balloon going up is utter RUBBISH. The air around is not "pulled" any harder by gravity than the baloon...

Buoyancy is the actual reason for helium baloons and ships floating...

7th graders learn this in physics....

It actually goes down (mass center of gravity)

Doesn't this have to do with the fact the ramp is a triangle, cause its like those ball contraptions were if the ramp slants in ward the ball moves forward even if its flat, so it has to deal with the shape of both objects (guessed before answer) even if you don't believe me

The spirit level was showing the other way …

WTF just happened.
The older you get, the better you rolled upward , unless you’re a banana.”

Not weird at all. It rolls in this direction because it descends by rolling in this direction. It is not "rolling up" despite that the rails go up. It rolls down, because its center of gravity moved down.

Is this impressive to anybody?
I expected something cool, but this is like a 2nd grade physics demo.

Sireously, is there anybody who saw the shape of the ramp and couldn't immediately tell that he would put a narrowing dowel on it to make it go up? 😮

Thanks for the inspiration

Geez... don't dress simplistic illusions as science. Nothing here is rolling up. Just... don't!

If anyone of you have ever played the game shoot the moon it’s the same idea

Pfuh, screw gravity ! (Begin to levitate to space)

Simple put, the center of mass is descending , goes down in both cases.

Basically it's the design.

triks of camera

Umm. It isn’t strange for a moment..

The center of gravity of the body actually moves downwards because of the conical shape of the ends and the V shape of the track. Everything is normal, no magic.

In other words, it rolls down

at :47 seconds in the video your level in the background shows the slant going the other way.

Dutch was wrong you CAN fight gravity

Don’t say things float due to other things falling faster. That is incorrect, gravity causes everything to fall at the same rate. Things float due to buoyant force and a difference in density

You are magician 😂😂😂😂

It doesn't roll uphill. And it's very easy to spot. There is a level behind it. You can see that the object is consistently getting lower and lower. How can the object be rolling uphill while loosing altitude relative to level?!

Moment of inertia in visual form.

Nothing magical- just physics.

You didn't explain anything in this video. Thanks a lot.

I read the first sentence of the top comment and instantly understood why it was happening.

It is a simple spell, but…

We had this Toy in our School 😂

very smart explanation! congratulations!

Probably as long as it's center of mass goes downward in direction, ie. the direction that gravity is pulling in it's net force, the thing will move in that direction as long as it is permitted to do so via all other forces.

I'm wondering if u can use the physics effect of gravity to make and engineer things like this to make better things or vehicles

Gravity is gravity.Even the Jupiter is obeying it.
The design is clever though

By Rolling downwards Centre of mass would also end up on a lower point. It’s just the shape of the slope which forces direction right? Until it is too steep at least

You can see by the center of the object that it's technically rolling downhill. The slope of the sides combined with the V shape of the guided sum to a downhill slope despite the rails running uphill.

It's nice, but reasonable, still nice trick

I would imagine there was a motor in that weird shape.

"I walked uphill both ways on one foot!!!!"

my cars windows also roll up

The mass of the roller is in the middle that's why it rolls upwards
