You must sit there, otherwise you will not be able to receive the quests following directly from the goblin.
The same two cylindrical bottles are filled with equal masses of sand and water and rolled down an incline of equal height.
The Klein bottle over there. There is a hole at the bottom. No matter how you pour the water, it can't stay inside forever. Therefore, scientists believe that it is a bottlee in four-dimensional space. Even if you put all the water on the earth, it will be. not be full. Only in four-dimensional space can the bottle be filled with water.
Some people have experimented with manufactured Klein bottles. They can be filled with water. The Klein bottle theory is often considered false, but remember that we exist in three-dimensional space. The Klein bottle is not a Klein design in the true sense of the word. Only in four-dimensional space can the Klein bottle be connected without the hole between the bottle body and the bottom of the bottle. Only in this way can the Klein bottle truly have no holes. inside or outside and without borders, since there are no borders, of course they will never be full.
What is different from the bottle of drinking water is that it is as boundless as the sky, it does not haveneither exterior nor interior walls and that it can extend to infinity. The surface has no end, which means that the surface is unlimited. the sum is a plan, not the plan we understand. No matter where the bottle enters or penetrates, every place it passes is the outside of the bottle.
For example, if you put a small insect inside, it will crawl by itself and will not store the injected water at all. So it's basically a weird thing with an exterior but no interior. In the scientific field, it is the explanation in the mathematical field which is the non-directional plane, which is the best interpretation of the Klein bottle. Some people will explain that what they see is a bottle, so why is it a flat surface? In fact, to the naked eye it looks like a ball or a closed curved surface.
Detailed information
The Klein bottle is a conceptual model in thefield of mathematics, a non-directional plane without "inside" and "outside", just like a two-dimensional plane. One day in 1882, the famous mathematician Felix Klein discovered the existence of this "bottle", and the Klein bottle was given its name
The structure of a Klein bottle can be simply described as: there is a hole at the bottom of a bottle, and the neck of the bottle extends towards the inside of the bottle and. is connected to the hole at the bottom of the bottle.
It is an object without borders and without distinction between the inside and the outside. A small insect can never fly directly from it. bottom of the bottle along the surface outwards without passing through the bottle.
In fact, the "Klein bottle" was originally called the "Klein plane". Due to transliteration errors and misunderstandings, the Klein bottles created in reality are just bottle-shaped objects made by peoplennes who reluctantly pass the bottleneck through the bottle body in order to be reflected in three-dimensional space, and the theoretical "Klein bottle" The structure of "Plane" is not exactly the same. The real Klein bottle is a curved surface that can only be expressed in four-dimensional space.

It depends if it is full. According to density = mass/volume, the density of sand is about 2.5*10^3, and the density of water is only 1*10^3
So when the mass is the same, the volume of sand is small, so when the water is full, the sand should not be full.
If the sand is not full, according to the conservation of water energy, the total potential energy is the same, so look at the energy loss, the energy loss is friction. The friction between the inclined surface and the bottle is the sameme and the coefficient of friction between the sand in the bottle and the bottle is greater than the friction. coefficient between water and bottle, so the energy loss of sand is large, so the kinetic energy at the bottom is less than that of water, E=1 /2mv^2So water is fast.
