Odium, I remember the police saying that it was high explosives that was used in the attacks. And that it wasnt stuff you could make at home.
High Explosives
These are normally employed in mining, demolitions and military warheads. They undergo detonation at rates of 1,000 to 8,500 meters per second. High
explosives are conventionally subdivided into two classes and differentiated by sensitivity:
Original or Primary. These are extremely sensitive to shock, friction, and heat. They will burn rapidly or detonate if ignited.
Secondary or Base. These are relatively insensitive to shock, friction, and heat. They may burn when ignited in small, unconfined quantities;
detonation occurs otherwise. These are sometimes added to a primary in a small amount in a blasting cap to increase the cap's power.
Some definitions add a third category:
Tertiary, also called blasting agents. These are so insensitive to shock that they cannot be detonated by practical quantities of primary explosive,
and instead require an intermediate explosive booster of secondary explosive. Some examples would be T.N.T.(trinitrotoluene), RDX, or HMX. These can
usually fit into the Secondary group.
Note that some explosive materials can fall into no specific category, according to how they are initiated. For example, nitrocellulose deflagrates if
ignited, but detonates if initiated by a strong detonator.

Just trust me, I'm not going to explain nor post links which do, but any of those high-explosives lister there, can be made if you know what to buy.
A friend of mine whose living is knowing such things sat down and explained it to me about 3 or so years ago.
