HOW TO MAKE A PIPEBOMB
Ingredients:
Ammonium nitrate (not less than 32% nitrogen)
Fuel oil or gasoline and motor oil 1:1 ratio
Two flat boards
A bucket or other container for mixing ingredients
Iron or steel pipe or bottle
Blasting cap
Wooden rod ~ 1/4 inch diameter
Spoon or similar measuring container
Step 1: Spread a handful of 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 minutes)
Step 2: Mix one measure (cup, tablespoon, etc.) of fuel oil with 16 measures of 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 of the measure of motor oil. Store in a waterproof container until ready to use
Step 3: Spoon this mixture into an iron or steel pipe that has an end cap threaded on one end. If a pipe is not available, you may use a dry tin can, a glass, or a heavy-walled cardboard tube (NOTE: Take care not to tamp or shake the mixture in the pipe. If the mixture becomes tightly packed, one cap will not be sufficient to initiate the explosive
Step 4: Insert the blasting cap just beneath the surface of the explosive mix (NOTE: Confining the open end of the container will add to the effectiveness of the explosive
