The Festival of Cultures is an annual event to celebrate the wide range of cultures found in our great state. People representing 40 cultural groups will share their traditions and customs. Here are just a few of the festival's many activities.
Crafts: See the fine art of basket weaving from Vietnam and Zimbabewe. Watch the delicate art of making paper umbrellas from Thailand and the decorative craft of paper picado, or paper cutting, from Mexico. All craft demonstrations provide a firsthand view of how things are made. You will appreciate the process involved in making these products.
Music and Dance: Experience musical instruments that you have never heard before. Listen to the music of a sho from Japan, a bull-roarer from Australia, a sitar from India, and a chakay from Tailand. You will also be entertained by folk dances from around the world, such as the troika from Russia and the mayim mayim from Israel. From 1:00 P.M. to 3:00 P.M. on August 14, special folk-dancing classes for children will be offered. Children ranging in age from 6 – 8 can learn the kinderpolka from Germany. Children ranging in age from 9 – 12 can learn the raspa from Mexico.
Storytelling: Listen for hours as professional storytellers charm you with captivating tales. Fables, folktales, and ballads from various countries will be told. By popular demand, Gwendolyn Washington, a famous African American storyteller, is back.
Food: Enjoy irresistible foods from other countries, such as gyros from Greece, seafood paella from Spain, crepes from France, and tandoori chicken from India. These tasty dishes will be difficult to pass up.
