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.

The Metropolitan Police have confirmed there is an ongoing security alert at the Palace of Westminster.
The BBC understands that only MPs and peers can enter the building, but people are being allowed to leave.

That ongoing security alert at Westminster is a false alarm as quoted on Sky News channel just now.

Not sure if this has ben posted yet......could'nt see it but they've found explosives in the car at Luton and are checking another car in another location....heres the link.

www.sky.com...

What i am waiting on is the details of what exactly they have found at the house in Leeds. On Sky News earlier they already stated it was a "bomb factory" of sorts which is fair enough and that they did a controlled explosion, however just now on the telly the head of the anti terrorist department stated that the investigating police at the property were dealing with certain "materials" that they needed to be sure were'nt putting the public at risk.

I just hope they are talking about explosives! If they are i wish they'd say EXPLOSIVES and not just "materials".....can get people a little worried that sort of talk can.
