The action of a top is described by equations of rigid body dynamics (see the section Rotation in three dimensions).
Typically the top will at first wobble until the shape of the tip and its interaction with the surface force it upright; contrary to what is sometimes assumed, longstanding scientific studies (and easy experimentations reproducible by anyone) show that less friction increases the time before the upright position is reached (unless the top is so unbalanced that it falls before reaching it).

Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion.Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.The motion of a top is produced in the most simple forms by twirling the stem using the fingers.More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger.
