^ that **** really exploded, literally.
Isn't fertilizer used to make many bombs, such as the one used in the Oklahoma City bombing?
Is it explosive by itself or only when combined with other ingredients?
Ammonium nitrate can make most anything made of carbohydrates explode. One great example is ANFO (ammonium nitrate + fuel oil) which is used for blasting in mines, but was also mixed with nitromethane to make the Oklahoma City bomb. Nasty stuff.
Even with nothing else it can detonate, disastrously. Back in 1947 shiploads of AN detonated and leveled major portions of Texas City, Texas. As strong a blast as a small nuke; 2,300 tons of AN just on the one ship. Cause: a small fire.
