The main tool used in the sport of curling is a curling stone (or rock). These heavy stones are made of granite and are slid on a sheet of ice towards a target area, known as the house. Players use a broom to sweep the ice in front of the stone, impacting its speed and direction. Curling requires precision, strategy, and teamwork, as teams aim to position their stones closer to the center of the house than their opponents. Mastery of the curling stone’s weight and trajectory is essential for success in this unique sport.
