Fertilizer Explosive

An explosive munition can lie made from fertilizer grade ammonium nitrate and either fuel oil or a mixture of equal parts of motor oil and gasoline. When properly prciwrcd, this explosive munition can be detonated with a blasting cup.

Explosive MATERIAL REQUIRED:

Wooden Rod

4. Place the aluminum metal on top of the explosive.

5. Just before use, insert the blasting cap into the cavity made by the rod. The initiator is now ready for use.

Cardboard Disk Insert For Handling Purposes

NOTE: If it is desired to carry the initiator some distance, cardboard may be pressed on top of the aluminum to insure against loss of material.

Ammonium nitrate (not less than 32'. nitrogen) Fuel oil or gasoline and motor oil (1:1 ratio)

Two flat boards. (At least one of these should lx? comfortably held in the hand, i.e. 2x4 and 3i> x M.) Bucket or other container for mixing ingredients Aluminum Iron or steel pijie or bottle, tin can or heavy'-walled cardboard tul>e Metal Blasting cap

Wooden rod - 1/4 in. diameter Spoon or similar measuring contemner

PROCEDURE:

Blasting Cap

1. Spread a han IKu of the ammonium nitrate on the large flat board and rub vigorously with the other board until the large particles are crushed into a very fine powder that looks like flour (approx. 10 min).

NOTE: Proceed with Step 2 as soon as possible since the powder may take moisture from the air and become spoiled.

2. Mix one measure (cup, tablespoon, etc.) of fuel oil with 10 measures of the finely ground ammonium nitrate in a dry bucket or other suitable container and stir with the wooden rod. If fuel oil is not available, use one half measure of gasoline and one half measure of motor oil. Store in a waterproof container until ready to use.

HOW TO USE:

This particular unit works quite well to initiate charges of five pounds of flour, 1/2 gallon (1-2/3 liters) of gasoline or two pounds of flake painters aluminum. The solid materials may merely be contained in sacks or cardboard cartons. The gasoline may be placed in plastic-coated paper milk cartons, plastic or glass bottles. The charges are placed directly on top of the initiator and the blasting cap is actuated electrically or by fuse depending on the type of cap employed. This will destroy a 2,000 cubic feet enclosure (building 10 x 20 x 10 feet). 15

3. Spoon this mixture into an iron or steel pipe which has an end cap NOTE: For larger enclosures, use proportionately larger initiators threaded on one end. If a pipe is not available, you may use a dry tin and charges. 5 ^ Solid can, a glass jar or a heavy-walled cardboard tul>e.

Charge in Carton

NOTE: Take care not to tamp or shake the mixture in the pipe. If mixture becomes tightly packcd, one cap will not be sufficient to initiate the explosive.
