This lecture explores the decoiling effect observed when pouring high viscosity fluids from a height, using examples like shampoo and honey. The instructor presents an experiment to characterize the phenomenon by manipulating parameters such as jet diameter, temperature, and flow rate. The viscoelastic nature of honey is discussed, along with the formation of a coil upon impact. Simple equipment like a funnel, ruler, honey, and camera are used to conduct the experiment, with assumptions made about temperature and viscosity. By recording the process at varying heights, the evolution of the phenomenon is observed to draw conclusions.
