This paper presents secure upper and lower estimates for solutions to the equations of
rigid body motion in the Euler case (in the absence of external torques). These estimates are
expressed by simple formulae in terms of elementary functions and are used for solutions that
are obtained in a neighborhood of the unstable steady rotation of the body about its middle
axis of inertia. The estimates obtained are applied for a rigorous explanation of the flip-over
phenomenon which arises in the experiment with Dzhanibekov’s nut.
