Herein we present a new adaptation of the classic flame or rainbow demonstration displaying the atomic emission of inorganic salts where organic solvents are used in a safe manner, thereby preventing incidents or injury. The flame test demonstration (subsequently referred to as the flame test) is a well-known and informative experiment; however, it can be dangerous if performed incorrectly. This version of the classic flame test applies the R.A.M.P. method of hazard risk assessment to provide a safer alternative to past variations. This new flame test allows for an impressive demonstration of atomic absorption and color emission of ionized gases in a safe environment.
