We review here a series of experiments on the fragmentation instabilities that a liquid drop undergoes it falls inside a fluid with which it is miscible, so called the solvent. Motivated by the original experiments initiated ...

As a drop of fluid is deposited on the surface of a miscible fluid (that we call the solvent), I tundergoes a strong pulling due to its surface rupture and it acquires a kinetic energy independently of gravity. For the ...
