Time Delayed Incendiary Devices

This is another simple electrically timed incendiary device for use in both buildings and vehicles. Make sure you don't leave any finger prints on any part of the device, wear gloves at all times when manufacturing and placing any incendiary device. All you need is a mechanical kitchen timer, a brand new 9v battery (w/cap), an automobile backup light bulb, some thin electrical wire, some strike anywhere matches and a soldering iron.

First you break off glass on the bulb so as to expose the filament, being careful not to break it. Heating the glass with a lighter and then touching it to cold water usually does the trick. (Instead of a light bulb you may want to use a model rocket engine igniter.)

Now with your soldering iron, attach one wire from the battery cap to the tip of the bulb, and then solder a 6-8 inch length of wire to the metal side of the bulb's base. (When the other tip of this wire is connected to the second wire from the battery cap/battery, the circuit will be complete and the matches will ignite . . . that's the general idea.)

Take the kitchen timer and glue a toothpick or match stick to the rotating pointer, in effect extending the circumference of the rotation. Glue the two loose ends of the wire to the non-moving section of the timer at the 12 - o'clock position, so that the toothpick on the pointer will connect the two wires when it winds down to zero. (Make sure not to connect the battery until you are about to set the timer).

Now you can set your timer for up to an hour and leave. You will need a little more to make your fire go. Suggestions include attaching match heads to the igniter and putting it in a pile of fire-starter gel, next to a plastic bag of starter fluid in the middle of a pile of charcoal, or in a small packet containing a mixture of half sodium chlorate (weed killer) or potassium nitrate (saltpeter) and half white granulated sugar. You can help along your fire by placing your device on top of or beside a plastic container of any flammable liquid (kerosene/gasoline/etc.).
