The technique and results of an experimental study of the effect of the surface tension coefficient and the initial volume of a water core on the dynamics of its destruction at free settling in air with a non-zero initial velocity are presented. It is shown that the distance over which the water core completely collapses with the formation of the cloud of droplets decreases by 30% at two-fold decrease in the surface tension coefficient of a liquid. It is shown that the dependence of distance of complete destruction on the initial core volume has a minimum.
