  Confinement of a chromodynamical string can result in specific effects in
scattering processes and multiparticle production. In particular, due to its
rotation secondary fragments of the splitting apart string can move like stones
thrown from a sling. That would be detected as the azimuthal asymmetry of
particle distributions in individual events. Thus we propose to explain the
elliptic flow observed in AA-collisions as a sling-effect. It can provide
information about confinement of quarks inside particles or binding forces in
nuclei. Nonclassical states of the created particles like the Schroedinger cats
are produced. Some classical and quantum-mechanical estimates of possible
effects are given. Experimental facts which can be used for their verification
are discussed.
