These six complete, broken or partially drilled flywheels were likely used for either spinning yarn or to help in drilling holes. They can also be called spindle whorls or perforated discs. All of the flywheels were made from broken pottery sherds, reshaped and repurposed for a new function. They were recovered from House 2 at the Minneapolis site, a Smoky Hill phase site occupied during the Middle Ceramic Period, in 1934 by the University of Nebraska and donated to the Kansas Historical Society in 1987.
