There are at least two directed entities in nature: vectors and spinors.

The most common examples of vectors are forces, e.g. the force which a police officer applies to push a suspect into prison. When the officer is rotated by 180°, he will forward the subject outta jail. But when the officer is rotated by 360°, he is again in the right position to punch the culprit into the dungeon.

The most common examples of spinors are palms. Normally you got two, but one is enough to understand what a spinor is and how is behaves.

Your palm is a directed entity. It has a wrist and fingers. To possess spinoric properties, one finger is sufficient. In our video, we fastened a pencil with a red tip on the middle finger. For the spinoric properties, however, it is essential that the palm is connected to the body by the arm. Your arm is flexible, but after all motions you better make sure that it isn't twisted if you want to stay healthy.

Now watch the thickish and elderly student in the movie. He still is pliable enough to rotate his right palm plainly. We coerced him into performing a plain rotation by placing a glas filled with reddish fluid onto his palm. While he rotates his palm he pronounces the angles of rotation: 0 degrees, 90 degrees, 180 degrees, 270 degrees, 360 degress ... At 360° the palm isn't at its initial position since the arm is twisted. The student has to go on: 450 degrees, 540 degrees, 630 degrees, 720 degrees. At 720° palm and arm are again in their initial positions. It is most important that the arm is untwisted by continuing the rotation, rather than by reversing it.

720° is twice 360°. The student and everybody else, you too, must rotate their palms not at all or TWICE to have them back at their original positions. This is the property which differentiates spinors from vectors. Generally one may say that spinors possess tighter bindings to their surroundings than vectors.

Many physicists believe that spinors are peculiar to quantum mechanics and appear only with microscopic objects, for example electrons, protons and neutrons. These physicists are stupid. Almost every object in nature may become a spinor when it is connected to its surroundings suitably. See for another example

For electrons, protons and neutrons, the connections with surroundings are established by magnetic fields. The consequences for the structure of matter are universal. For example, there would be neither the chemical elements nor chemical bindings as we know them if the electrons weren't spinors.

The procedure shown here is known as Philippine Wine Dance. Some Filipina girls performing it can be seen on
Yet this is an idealistic demonstration. In real life everybody is awfully drunken. The elected victim is loaded with three glasses (two on his palms and one on his head, all filled with sticky liqueurs) and is persuaded to dance the wine dance twisting both arms at the same time. The inevitable catastrophe ensues. The drunkards laugh and are happy (except the victim).
