=** Famous Ancient Inventions That Revolutionized The World ** =

Here are some of the greatest ancient inventions that were ever made. One of these inventions I just ate last night, Pizza! I really hope you learn something from this page!

__**The Invention of Paper**__ The Egyptian didn't make paper by using trees, but by this plant called papyrus. This plant were abundant along the Nile river. The reed was normally 2-3 meters tall. The process of forming paper from a plant is very interesting! Papyrus was not only used for paper, but were also used for boats, baskets, mats, mattresses and sandals. The process were long and tedious and I think it needs a lot of patience. It starts with the papyrus reed being dipped in water to get rid of any excess dirt and sugar. Then it was pounded dry and placed somewhere sunny for it to dry. The last step is to weave it in a criss cross motion. After the papyrus is made, it can be used for writing ancient Egyptian calligraphy or drawings. Now paper is used world wide in schools, printers and books. The modern way of making paper is buy using trees not papyrus and the good thing about using paper is that their made from trees and we can recycle and use it over and over again.  

__**The Invention Ox-Drawn Plow**__ Out of all inventions the Egyptians had invented. I think that the ox-drawn plow is most interesting, because of how it changed process of farming and made it much easier to harvest crops. This handy invention saved farmers long hours of work in the fields. They used the strong strength of the ox to plow the fields. It works by tying rope from the ox to the plow. The string was normally tied to the ox's horns. This fantastic invention greatly helped Egyptian agriculture. Nowadays we mostly don't use animals to plow our fields except for third world countries. The reason why we don't use animals now is because it is too slow and there is faster ways to do the jobs with our modern technology.



__**The Invention of the Clock** __ The Egyptians invented two types of clocks, the sun clock and the water clock. Both of these clocks were used a lot and were very useful.

__Sun clock__  The sun clock worked by the movement of shadows which formed a kind of sun dial. They have numbers all around where the sun was shining and they normally put a pole and figure there. Where the shadow lands on it what time it is! They could divide day, into morning, afternoon and night. They also can tell the longest and shortest years depending on the time of year. How they can tell is but watching the shadow if it's longer or shorter.

 __Water clock__ The water clock was first found in a tomb of the pharaoh Amenhotep. The clock is long a slating, this allows the water to slowly drip down at a consistent rate into a small hole at the bottom.



<span style="font-family: 'Comic Sans MS',cursive; font-size: 16px; line-height: 24px;">The clock is a international recognized device and there are now different types of clocks and watches, analog or digital. We use clocks every day and probably in our modern world we can't live without it!

__<span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">**The Invention of the Lock** __ <span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">At that time the Egyptian were very cautious about there belongings so they wanted to prevent robbers from coming in the there homes. 4000 years ago they invented this ingenious invention which we still use today. The lock! How it works back then is that there was a key which has ridges, when the ridges meet with the pins inside the lock, the pin's drop, leaving the door open! We are almost certain that the lock was invented in ancient Egypt but we still don't know who invented it! This inventor saved the world from a endless wave of robberies. For without the lock!

<span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">Locks are really important nowadays because of the rising rate of house robbery's. Robbers now also know more about valuable things like jewelry, cars and wallets. There is a evolution of the locks too, although a lot of people use locks with keys, there are also fingerprint locks and voice locks!

__<span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">**The Invention of PIZZA** __ <span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">One of my favorite foods that was an ancient invention is the PIZZA! Historians say that the pizza was invented together by the ancient Greeks in Italy and the Etruscan. Although we think of pizza now as fast and hot food, it was considered a peasant meal in ancient times. Although we still don't know who invented this invention, It definitely revolutionized the world! Now there are many pizza restaurants including Domino, Pizza Hut and other small pizzerias

__<span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">**The Invention of Concrete** __ <span style="font-family: 'Comic Sans MS',cursive; font-size: 16px;">The Romans invented what we call today concrete. The word concrete comes from the Latin word "concretus" which means grow together. There were numerous structures constructed with concrete including the "Pantheon" in Rome. The moldeble liquid takes hours and days to turn into solid concrete. It is hard to imagen our modern world without concrete, for without concrete we wouldn't have most of the structures we have now. Today concrete is widely used to build high rises, bridges, roads and homes. We use about 5 billion tonnes of concrete every years and continues to stagger every year! <span style="font-family: 'Comic Sans MS',cursive; font-size: 16px; line-height: 24px;">
