In one illustrative form a shooting gallery kit is disclosed that includes a shooting gallery. The method includes identifying, in a database, at least one of several previously recorded spectra that is similar to the recorded first spectrum. This integrates a uniform reaction injection device, a gas mixing component, and a catalytic initiator within a section designed to be installed between compartments used to promote an endothermic process. The variable moving picture reproduction module reproduces the variable moving picture so that the variable moving picture is realistically reproduced.
