The spectacular experiment of exhibition chemistry, known as Golden Rain, simple precipitation and recrystallization of lead iodide, is particularly useful in teaching practice because of its innumerable connections to key topics of the school program of Inorganic Chemistry (solubility, crystallization, precipitation, solubility product, solubility equilibria, Le Châtelier’s Principle), as well as to enable students to carry out focused stoichiometric calculations. A teaching path has been developed in order to take advantage of this potential.
