The production of paper is a process that involves the use of trees to make pulp, which is then transformed into writing material. Although paper is often thought of as being made from wood, it can actually be made from a variety of sources, including papyrus plants, which were used by the ancient Egyptians to make a form of paper over 3,000 years ago. The introduction of machines for papermaking in the 19th century made paper production more efficient and affordable. The method of papermaking involves mixing the fibers of wood with water until they become a soft, wet material that can be dried into paper.
Sweets are loved by people everywhere, not just children. At the writer's house, the whole family enjoys a sweet dessert after every meal, and the writer's favorite dessert was invented by mistake many years ago. The invention of ice lollies was the result of an eleven-year-old boy named Frank Epperson leaving a drink outside with a mixing stick in it, which froze and stuck to the stick. Although ice lollies were not sold in shops immediately, Frank Epperson opened an ice lolly factory 18 years later and today, millions of his creations are enjoyed worldwide.
Vaccines were a great innovation because they offered protection from disease, one of man's greatest enemies. In Europe, the Black Death killed between 1347 and 25 million people before vaccines were available. The first vaccine was created in about 1800, although the theory behind vaccines was not understood for another 50 years. Today, vaccines are given to most children in developed countries, but more are needed in poorer countries.
