Assume your theories
Our theories regarding this mystery of the universe:
It depends on the functioning of the brain's hemispheres. (We can add a fourth point regarding support. We unconsciously fear dropping an object, and as a result of our unconscious thoughts, we cannot spread our arms simultaneously to hold the object. However, we tried support in mid-air (a finger as support was extremely minimal, but we managed to spread our arms at the same time).)
It is physics.
It depends on the surface. (We used various objects with different surfaces (glossy, matte, etc.).)
It depends on support. (The object was on a flat surface and on various other objects, and we were able to spread our arms thanks to the support, but when we made a dent in the object, we were able to almost perfectly spread our arms apart in mid-air.)
It depends on the shape. (We tried using flat square objects, cylindrical shapes, and ovals—none of which worked.)
The theory of hand influence (is based on which hand a person most often uses for tasks (for example, the right hand is dominant).)
The theory of human temperature (we tried conducting the experiment with hands at room temperature (during the experiment with wet hands, we soaked our hands in cold water).)
The theory of friction? Interaction of skin with the object (We applied a restriction, using cotton pads as a barrier. After that, we wet our hands and tried to spread our fingers apart, resulting in no success.)
Help us understand what might influence this.
