It is shown that during the motion of two initially gravitationally bound spherical shells, consisting of point particles moving along ballistic trajectories, one of the shells may be expelled to infinity at subrelativistic speed v exp ≤0.25 c . The problem is solved in Newtonian gravity. Motion of two intersecting shells in the case when they do not runaway shows a chaotic behaviour. We hope that this toy and oversimplified model can nevertheless give a qualitative idea on the nature of the mechanism of matter outbursts from dense stellar clusters.
