Gunpowder, also known since the late 19th century as black powder, was the first chemical explosive and the only one known until the mid 1800s. It is a mixture of sulfur, charcoal, and potassium nitrate (saltpeter) - with the sulfur and charcoal acting as fuels, while the saltpeter works as an oxidizer. Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks.
Gunpowder was, according to prevailing academic consensus, discovered in the 9th century in China, attributed to Chinese alchemists searching for an elixir of immortality. This discovery led to the invention of fireworks and the earliest gunpowder weapons in China. In the centuries following the Chinese discovery, gunpowder weapons began appearing in the Arab world, Europe, and India. The consensus is that this was spread from China, through the Middle East, and then into Europe.
Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate at subsonic speeds, whereas high explosives detonate, producing a supersonic wave. Ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel. Gunpowder is thus less suitable for shattering rock or fortifications. Gunpowder was widely used to fill artillery shells and in mining and civil engineering to blast rock roughly until the 2nd half of the 19th century, when the first high explosive (nitro-explosives) were discovered. Gunpowder is no longer used in modern explosive military warheads, nor is it used as main explosive in mining operations due to its cost relative to that of newer alternatives like ANFO.
I asked my mother why do you cry
she said your brother had... he just died
Well I told him not to go outside
he said he had to fight for his country's right
But don't you know that mo-mother
don't you know that we can't stop the violence, no
Because the war is not over
until you can feel love, peace, and hear silence
But I smell gunpowder (pow)
my brother's been dead ever since
I didn't beleive it, but when I saw him I was convinced
Two shots to the head he was already dead Lord,
I headed for revenge in the city of Port Au Prince
Screaming bro-brother
don't you know that we can't stop the violence, no
Because the war is not over
until you can feel love, peace, and hear silence
But I smell gunpowder (Pow)
Zion's gunpowder (pow)
L.A.'s gunpowder (pow)
I wanna know why
Christians pray for a new day
we don't need no, we don't need no, we don't need no
But its still the same way
I wanna know why
ghetto people pray for a new day
hey, hey, heeey
and its still the same way
But the preacher man told me
good things come to those who wait
do good things come to those who wait?
I wanna know tell me
good things come to those who wait
do good things come to those who wait?
we wanna know, we wanna know, we wanna know
Pe-people
don't you know that we can't stop the violence, no
because the war is not over
until you can feel love, peace, and hear the silence
but I smell gunpowder (gunpowder)
Brooklyn's gunpowder (gunpowder)
Shaolin's gunpowder (gunpowder)
Uptown's gunpowder (gunpowder)
Jersey's gunpowder (gunpowder)
even New Zealand's gunpowder (gunpowder)
Australia's gunpowder (gunpowder)
Brixton's gunpowder (gunpowder)
I see you
Staring out from the printed page
the calm before the storm
in your breath
The sunset on the side
of your face
the moments between
life and death
One truth for the men who pushed
you into death
and one truth for the rest of us
we may be down
but not out
We're standing right in back of you
Static quotations, historical lies
Don't mean nothing
when your children die
just one more breath
the last word on your lips
The dust and the bruise
The gunpowder we choose
Soldiers of the hopeful masses
optionless
working classes
sending money home to keep illusion alive
standing right in back of me
Static quotations, historical lies
Don't mean nothing
when your children die
just one more breath
the last word on your lips
The dust and the bruise
The gunpowder we choose
We're standing right in back of you
One truth for the men who pushed
you into death
and one truth for the rest of us
(The rest of us)
we may be down
but not out
We're standing right in back of you
Static quotations, historical lies
Don't mean nothing
when your children die
just one more breath
the last word on your lips
The dust and the bruise
