1. Scarves were originally used as sweat towels. In ancient Rome over 2,000 years ago, men wore a piece of cloth around their necks or waists called a sudarium (meaning "sweat cloth") to wipe sweat off their faces while working in the hot sun!

2. Ancient soldiers wore scarves to show off their rank. Chinese Emperor Qin Shi Huang used neck scarves on his famous Terracotta Army warriors around 230 BC. The colors and fabric styles told everyone which military rank each soldier held!

3. Scarves don't actually generate heat. A cozy wool scarf doesn't create warmth on its own. Instead, its fluffy fibers trap air warmed up by your neck, creating an insulating layer that prevents your body heat from escaping into the cold air!

4. Soccer fans wear scarves to cheer for their teams. In cold European stadiums, soccer fans started wearing scarves decorated in their team's official colors in the 1900s. Today, crowds hold their scarves high above their heads in the stands to create a "wall of color" and sing team anthems!

5. Magicians use silk scarves because they squish tiny. Magic trick scarves are woven from ultra-thin silk threads. Because silk is so thin and flexible, a magician can wad up a giant 3-foot silk scarf and hide it inside a tiny fake thumb or palm!

6. Harry Potter fans identify house colors by house scarves. In the Harry Potter movies, students at Hogwarts wear striped knitted scarves to show off their house pride: red and gold for Gryffindor, yellow and black for Hufflepuff, blue and bronze for Ravenclaw, and green and silver for Slytherin!

7. Inca weavers made scarves out of alpaca fur. Centuries ago in the high Andes mountains of South America, Inca royalty wore soft, lightweight scarves woven from the fine fur of alpacas and vicuñas to stay warm in freezing mountain winds.
