Highly rotating drop impacts a thin layer. Upon the impact, a distinct, crown structure composed of a jet- like ejection and an obliquely oriented developing lamella is formed. The jet results from the merging of the crown rim at a specific angle after impact, leading to the creation of Fluid Chains that undergo Rayleigh- Plateau fragmentation into small droplets. Furthermore, a dynamic lamella results in rupture, forming a perforated, curved thin sheet with multiple holes that retract and collide due to the Taylor-Culick instability.
