2015 al-Qaeda Article Showed How to Build NY Christmas Bulb Bomb

The summer 2015 issue of Inspire featured, in a step-by-step tutorial from “The AQ Chef,” a homemade IED recipe consisting of a pipe packed with shrapnel, a 9v battery, wires, and a Christmas light in the circuit to put a three-second delay on the explosion. Per the instructions, the Christmas bulb — al-Qaeda used a green light in their example — is altered and filled with explosive powder to act as a delayed ignitor.
