The results of experimenatl study of drop movement and breakdown in a skirling viscous flow at small Reynolds numbers are presented. For the first time it is shown that at small Reynolds numbers the drop breakdown is observed at some critical Bond number values. The dependence of the critical Bond number value corresponding to drop shape instability by Rayleigh-Teylor mechanism from drop movement regime at Reynolds numbers Re = 0.03÷0.84 is experimentally found.
