Amelia walked nervously to the front of the classroom. She always hated public speaking, but in the name of her house, she had to do well. Smiling feebly, Amelia turned and waved her wand at the board where the following appeared:

Turning back to the face the class, Amelia spoke clearly despite her anxiety.
"Hello everyone! My presentation is on the history of fans. Fans are very important to not only muggles, but wizards too as we all experience the same weather and they can keep us cool in the heat. There are two types of fans, which are mechanical and implement.

An implement fan is hand-held and used by waving it back and forth to induce airflow for the purpose of cooling or refreshing oneself. Any broad, flat surface waved back-and-forth will create a small airflow and therefore can be considered a rudimentary fan. Generally though, purpose-made hand-held fans are shaped like a circle segment made of a thin material mounted to slats which revolve around a pivot so that it can be closed when not in use. We will be making an implement fan at the end of my presentation.

Fan history stretches back thousands of years. Since antiquity, fans have possessed a dual function – a status symbol and a useful ornament. In the course of their development, fans have been made of a variety of materials and have included decorative artwork. The simplest fans are leaves or flat objects, waved to produce a cooler atmosphere. These rigid or folding hand-held implements have been used for cooling, for air circulation, as a ceremonial device, and as a sartorial accessory throughout the world from ancient times. They are still widely used.

The earliest known fans are called 'screen fans' or 'fixed leaf fans'. These were manipulated by hand to cool the body, to produce a breeze, and to ward off insects. Such early fans usually took the form of palm leaves. Some of the earliest known fans have come from Egyptian tombs. Early Assyria and Egypt employed slaves and servants to manipulate the fan. In Egyptian reliefs, fans were of the rigid type. Tutankhamum's tomb possessed gold fans with ostrich feathers, matching depictions on tomb walls. Long-handled, disk-shaped fans were carried by attendants in ancient times and were associated with regal and religious ceremonies. They had handles or sticks attached to a rigid leaf or to feathers. Plumage of birds was used in fans, such as those of the Egyptians and Native American Indians, that had both practical and ceremonial uses. In the ancient Americas, the Aztec, Maya, and South American cultures used bird feathers in their fans."

Amelia paused and took a sip of water before continuing with the second type.
"The second type of fan is, as mentioned before, the mechanical fan. Mechanical fans are those such as ceiling fans, oscillating fans, computer fans, or blowers. It is a device used to produce an airflow for the purpose of creature comfort, ventilation, exhaust, or any other gaseous transport.

Typical applications include climate control, cooling systems, personal comfort, ventilation, winnowing, removing dust, drying and to provide draft for a fire. It is also common to use electric fans as air fresheners, by attaching fabric softener sheets to the protective housing. This causes the fragrance to be carried into the surrounding air.

The first recorded mechanical fan was the punkah fan used in the Middle East in the 1500s. It had a canvas covered frame that was suspended from the ceiling. Servants, known as punkah wallahs, pulled a rope connected to the frame to move the fan back and forth.

The Industrial Revolution in the late 1800s introduced belt-driven fans powered by factory waterwheels. Attaching wooden or metal blades to shafts overhead that were used to drive the machinery, the first industrial fans were developed. One of the first workable mechanical fans was built by A.A. Sablukov in 1832. He called his invention, a kind of a centrifugal fan, an Air Pump. Centrifugal fans were successfully tested inside coal mines and factories in 1832-1834. When Thomas Edison and Nikola Tesla introduced electrical power in the late 1800s and early 1900s for the public, the personal electrical fan was introduced. Between 1882 and 1886, Dr. Schuyler Skaats Wheeler developed the two-bladed desk fan, a type of personal electric fan. It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1882, Philip H. Diehl introduced the electric ceiling fan. Diehl is considered the father of the modern electric fan. In the late 1800s, electric fans were used only in commercial establishments or in well-to-do households. Heat-convection fans fueled by alcohol, oil, or kerosene were common around the turn of the 20th century.

In the 1920s, industrial advances allowed steel to be mass-produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1930s, the first art deco fan was designed. Before this fan, called the Silver Swan, most household fans were fairly plain. In the 1950s, fans were manufactured in colors that were bright and eye catching. Central air conditioning in the 1960s brought an end to the golden age of the electric fan. In the 1970s, however, Victorian-style ceiling fans became popular."

"And now, enough of this rambling, it's time for some fun!" Amelia exclaimed, as she pulled out this folded piece of parchment.

"I need everyone to take out a blank piece of parchment. I brought some muggle markers so you could decorate both sides of the parchment, if you desire." she passed out some markers, "However, you may also use your wand to add some decorations too."

"Once your parchment is all decorated as you desire, begin at the short side, and fold over and under, making 3/4 inch wide strips down the length of the paper. Hold one end of the folded paper firmly and for a more permanent effect, use a muggle staple to seal that end. By holding that sealed end, flip your wrist rapidly enough to create a breeze. And there you have it: a quick and easy implement fan!"

Amelia breathed a sigh of relief to be finished with her presentation. She hoped she hadn't bored her classmates too much and they at least learned something. With one last smile, "Thank you very much for listening to my presentation on fans and I hoped you enjoyed it."

As she was about to sit back down, Amelia quickly added, "Oh and enjoy those fans that you all made. They might be useful in some of our more stuffy classrooms." she winked and quickly made her way to her chair.
