One purpose of the inventive emulator is to function as an energetic witness substitute by replacing the detonator in an actual IED, thus enabling bomb technicians to conduct bench top and field analyses of IEDs, and to assess the effectiveness of render-safe procedures by, for example, illustrating how a detonator would react in a render-safe procedure.

Embodiments disclosed herein provide an Explosive Device Simulator (EDS). Embodiments of the Explosive Device Simulator may include two or more chemical components that are non-explosive when separated from each other within the EDS, but which form an explosive mixture or substance when combined. Because the individual chemical components are non-explosive, the Explosive Device Simulator may be stored, transported and handled safely for long periods of time and without increased security, protective measures, or special training. Further, the chemical components may be chosen such that the Explosive Device Simulator creates a realistic explosion (e.g. loud and bright), but which produces minimal concussive forces and is therefore safer to use as a training aid.
