In curling, players use brooms to maneuver a giant stone to the center of a bull's-eye. Historically, the brooms were made from natural fibers, but that has changed in recent years. A broom made with artificial materials, dubbed the "Frankenbroom," gave players more control over the stone—too much control, according to fifty of the top curling teams. As a result of the controversy, Frankenbrooms were banned in 2015. However, other brooms have also raised concerns. For this reason, Canada's World Curling Federation (WCF) and the National Research Council of Canada (NRC) joined forces to measure how different brooms affect the stone and the ice.
