!History!
Some ancient Asian alchemists were mixing some ingredients
together to
form a toffee they thought would make them live forever. They put
their
mixture on a small fire, not knowing they had made a mistake. The
mixture started to bubble and boil, and then it burst into
flames,
burning down their hut and singeing their beards. Without knowing
it
these ancient alchemists had made the first explosives.
The ancient Asians realized after a long while that the mixture
that
the alchemists had made could be used. They mixed many other
things
together and after many tried and failed attempts they found the
answer.
They tried mixing saltpeter and sulfur, two common materials, and
found
that the mixture actually detonated. They were very pleased with
their
accomplishment.
The Asians did not use their new creation for war. They made the
first
fireworks out of the substance. They used their fireworks as
signals for
many things such as signaling that another army was approaching.
The
Asians kept developing their creation, not using their knowledge
for
war.
The Asians finally designed a weapon for the need for one was so
great.
They took a hollowed piece of bamboo and filled it with the
powder. Then
they stuffed arrows in it. These were the first rockets. The
Asians
tried to keep their new invention to themselves, not letting the
outside
world know of it.
But their secret couldnšt last
for ever. The information leaked to the
Arabs who absorbed the new knowledge quickly. The Arabs made the
Asian
weapons and brought the knowledge westward.The Arabs transferred
the
knowledge on to the Europeans who, just like the Arabs absorbed
it
quickly.The era of explosives had begun.
In the 1200šs Roger Bacon, a European, was interested in the new
knowledge. He studied it and tested it over and over again. After
many
months he found the perfect ratio of saltpeter, sulfur, and a new
ingredient, charcoal. After he found out the perfect ratio he
wrote the
ingredients and the amounts in code in his diary. Roger Bacon had
made,
and recorded, the first black powder(the early form of
gunpowder).
One-hundred years after the discovery of Roger Bacon, a man named
friar Berthold Shwarts looked into this black powder. Bacon did
not get
credit for the making of black powder because he didnšt use his
invention. Berthold Schwarts saw this and put his mind to work.
He
thought and tried many things and finally thought of a great
idea.
Schwarts took a long iron tube and closed one end except for a
tiny
hole. He filled the tube with black powder and stuffed a small
pebble in
it. He touched a flame to the tiny hole and the pebble shot
through the
air with great speed. Schwarts had invented guns.
Soon guns became cannons which could launch boulders through
stone
castle walls. The age when the rich barons could sit in their
castles
and feel safe was over. The age when nights could don their armor
and
feel like a winner before the battle was over. A new age of
brutality
had begun.
Gunpowder also sped up the very slow process of digging up
stones. With
gunpowder they could blow the stones out of the ground. Before,
only the
rich people could have stone houses because it took so long. Now
even
some poor people cold have a house of stone. This was a great
technological step.
Five hundred years after Berthold Schwarts ever made guns and six
hundred years after Roger Bacon ever played with sulfur and
saltpeter,
an Italian scientist named Ascano Sobrero, thought of a new idea.
He
mixed nitric acid and glycerin together to see what would happen.
The
new substance nearly exploded in his face! Sobrero called his new
creation nitroglycerin. He was then added to the list.
Ascano Sobrero did many tests on the new liquid. He saw that the
highly
unstable mixture was very powerful. He knew that nitroglycerin
was very
dangerous. Sobrero played with the nitroglycerin, but didnšt use
it.
This was the same mistake that Bacon had made.
Many years later, in the 19th century to be exact, a Swedish
scientist
tried his luck with nitroglycerin. Alfred Nobel tried putting dry
substances into the unstable mixture. He tried putting many
things in
it, including jelly. This did fairly well but it didnšt burn
well. He
then tried putting in wood shavings and charcoal, but they
didnšt help
in making it safer to handle. The wood shavings actually made it
more
unsafe. This was not an easy job for Nobel.
One day the idea popped into his head. Nobel went and got some
kieselguhr , a German material that is made of small, fossilized
remains
of sea animals. When he got back he mixed the dry powder with the
nitroglycerin. He tested the new substance and found that it
worked. He
found that kieselguhr could absorb many times its own weight in
nitroglycerin. This was one of the many true great inventions.
Nobel named his invention dynamite. This was one of the first
high
explosives. People used the new explosive for excavating and
tunneling.
Nobel got the credit for not only nitroglycerin but dynamite,
too. Nobel
became very rich and famous.
Many years later Alfred Nobel died. He left his death money for
prizes.
The person that did best in some certain categories got thousands
of
dollars for their work. The prizes were given to the best in
Chemistry,
Medicine, Physics, Literature, and the promotion of peace. The
prizes
were, and still are, given out yearly.
