Pipe Bomb Here !

During the zombie apocalypse game such as Left 4 Dead, the most awesome weapon that I like in Left 4 Dead is the pipe bomb.

If I am not mistaken, the manual is leaked from US military survivor manual. But who cares where it is leaked from. You just know that you know how to make a pipe bomb !

This instruction manuals may be illegal in certain countries but I just share it out for educational purposes.
There are some disclaimer about making a pipebomb.

(1) First, you may do it but please double check with your state and your local province law before you even attempt on making this.It is probably mostly illegals but check it to be on safe side.
(2) Safety precautions, you may not want the things to explode when you hold it, do you ?

So , behold, this is the manual !
You may want to double click it to get bigger pics format.
