Figure shows formation of two secondary drops of unequal size and their merger. The process is same as the earlier process until t= 0.039 Tc with necking occurring at two places, one at the bottom of the column and the other at the middle. The necking at the middle of the liquid column is due to Raleigh instability. At t=0.04Tc two secondary drops are formed. These two drops later merge to form a single drop. Charles and Mason (1960) had observed that a primary water drop with initial diameter more that 6 mm yields two secondary drops of unequal size while coalescing with a Benzene-water interface.
