  An interesting physical phenomenon, which contradicts our common sense, is
concerned with the dynamics of motion of a spinning ellipsoid in a non smooth
surface. A hard-boiled egg spinning on a table with a rough surface is an
example. In this article, we present a theoretical explanation, of the dynamics
of motion of this ellipsoid, that describes the axis raising phenomenon, from
the horizontal to the vertical. The equations of motion were obtained with
Lagrangian formalism.
