The marionette also known as squiggle is a simple traditional toy, generally small in size, consisting of a rigid object with rotational symmetry, provided at one end with a sharp point. When set in motion by rapid rotation about its axis and released on a flat surface, the puppet must maintain its vertical position as much as possible, rotating in balance on its tip. It works on the same principle as the gyroscope. Such toys have existed since Antiquity, when they were attested in numerous cultural areas. They have maintained their popularity throughout history, being extremely widespread and beloved to this day.There are many constructive variants and different forms of titirez, but the basic characteristics are always the same, dictated by its mechanical properties: a balanced mass (center of mass located on the axis of rotation); a large value of the moment of inertia in relation to the axis (masses distributed far from it); a point contact with the support surface, located on the
