Problem 10: Droplet Explosion

When a drop of a water mixture (e.g. water-alcohol) is deposited on the surface of a hydrophobic liquid (e.g. vegetable oil), the resulting drop may sometimes fragment
into smaller droplets. Investigate the parameters that affect the fragmentation and the size of the final droplets.”
