Inert Homemade Pressure Switch

The X-ray correct, inert, homemade pressure-switch firing circuit contains all of the necessary components of an improvised explosive device (IED). The circuit is fully functional and will demonstrate that the firing switch has been activated by illuminating the LED in the blasting cap. The circuit board contains an X-ray correct battery, wire, switch, detonator, and inert explosive.

Powered by a 9-volt battery, the inert device represents a circuit that is completed when two saw blades are pressed together. The extra gelatin dynamite simulant is wired into a 9-volt battery with a mini relay switch inside of an ABS box. The blasting cap is a commercial bridgewire aluminum detonator.
