There is also a nickname "Roaring Race" in curling competition, because the thrower has to shout: "Wipe!" There are also athletes running with pots to wipe the floor with a brush board! It's not exactly cleaning the floor, but brushing the ice. The ice brush keeps brushing the ice in front of curling, in order to reduce the friction between curling and the ice surface and let curling go further.
Moreover, when the ice brush brushes the ice in front of the curling, the friction between the ice brush and the ice will generate heat, which will make the ice melt a little, thus forming a thin water film between the curling and the ice, which can reduce the friction coefficient between them and make the curling go further.
Rules of curling competition
In curling competition, each game is played by two teams, and each team consists of four players. The game played 10 innings. Players from both teams have two curling opportunities, that is, two pitching opportunities. The two teams pitch alternately according to the order of first base, second base, third base and main force. When one player throws the ball, two players of our team quickly brush the ice in front of curling, so that curling can reach the center of the camp accurately. At the same time, in order to keep curling away from the center of the circle, the opposing team members can also sweep the ice in front of curling.
When the player throws the ball, he squats down, pushes the ice pedal forward on the pedal device to make his body kneel forward and slide, and at the same time pushes the ball forward from the center of home plate with a curling hand. When he reached the avant-garde line, he let go of curling and slid to the center of the camp in a straight or arc trajectory.
While trying to slide the curling to the center of the camp, the bowler can also hit the curling of the opponent out of the camp or his own curling into the center of the camp under the command of the main players. Finally, when both players have finished curling, the winner will be decided according to the distance between curling on the court and the center of the camp. The team with more than one stone 1 minute wins.
