ingredients : ammonium nitrate ( not less than 32% nitrogen )
fuel oil or gasoline and motor oil 1:1 ratio
Two flat boards
bucket or other container for mixing ingredients
iron or steel`pipe or bottle
blasting cap
wooden rod - 1/4 inch diamter
spoon or similar measuring container
step 1: spread a handful of the ammonium nitrate on the large flat board
and rub vigorosuly with the other board until the large particles
are crushed into a very fine powder that looks like flour ( 10 minutes )

yoooo thanks

i can finally send this to my enemies

last steps

step 2: mix one measure (cup, tablespoon, etc..) of fuel oil with 16
measures of the finely grpund ammonium nitrate in a dry bucket or
other suitable container and stir with the wooden rod. If fuel oil not available
use one half measure of gasoline and one half measure of gasoline and
one half measure of motor oil. Store in a waterproof container
until ready to use.

step 3: spoon this mixture into an iron or steel pipe which has an end threated
on one end. if a pipe is not avaialable, you may use a dry tin can. a glass jar
or a heavy-walled cardboard tube
(Note: take care not to tamp or shake the mixture in the pipe. if mixture becomes
tightly packed, one cap will not be sufficient to initiate the explosive)

step 4 : insert blasting cap just beneath the surface of the explosive mix.

(note: confining the open end of the container will add to the effectiviness
of the explode)

Thanks for the tip
