A cooper will demonstrate his craft from noon to 5 p.m. Oct. 6 at Mennonite Heritage & Agricultural Museum, Goessel. Coopering refers to making wooden items such as buckets and butter churns.

Jim Gaster is a full-time cooper who lives near Indianola, Neb. His clients include the Smithsonian Institution, White House Visitor Center, Disneyland, Ordsall Hall Museum in Salford, England, and Hutchinson House Museum in Peterborough, Ontario, Canada. His work has appeared in several movies, including “The Alamo,” “Seabiscuit,” “The Legend of Zorro,” and “The Assassination of Jesse James.”

Children may assist Gaster with making a keg at 2 and 4 p.m. He will demonstrate the barrel-charring process at 3 p.m. His demonstrations will be part of Goessel Harvest Festival.
