Experiments have shown that in a collision of two clusters of vertical Bloch lines the laws of conservation of the topological charge and momentum are conserved, despite the considerable damping in the system. A head-on collision of two identical clusters gives rise to the formation of a breezer, whose lifetime is approxima tely equal to the relaxation time of the domain wall flexure.
