information on the internet about how to use one. you just don t see it used very often. again, it doesn t take much experience. you just need an oxidizer or fuel power source and if you use a timer or some other type of action command to detonate it, it is relatively easy, all available on the internet. tom, these sorts of bombs have been used by everyone from the would be times square bomber to the terrorist on the tiers of afghanistan, pakistan, i ve heard from many troops over there that there are lots of pressure cooker bomb eers and h difficult would it be for anyone to build this kind of thing? just go to the local retail store and buy it. you get a coupon and save money doing it. also when you re going through a check point if somebody looks inside the bag you could tell them you re on the way to open a soup kitchen or something. it doesn t have the appearance of a pipe bomb necessarily.
