      Everything can be "curling".
    The Beijing Winter Olympics will make many ice and snow sports popular, and curling, known as "chess on ice", is one of them

    .

      Curling is an expensive sport.
    The price of each curling in international competitions is about 15,000 yuan, and the price of a set of 16 curlers is more than 200,000 yuan

    .
    This is because the curling is made of granite from a specific origin.
    The raw materials are quite exquisite, and the production process is also very complicated.
    It takes 5 skilled workers 3 days to make a curling, and the curling is also very heavy, and each weight is very heavy.
    about 19 kg

    .

      There is another memory point in curling competitions, that is, during the competition, players have to hold ice brushes and "mopping the floor" all the time
    .
    In fact, the athletes are brushing the ice.
    Brushing the ice will make the ice surface slightly melt and make the curling slide farther.
    Another function of brushing the ice is to change the direction of the curling and find a better landing point

      The competition shoes worn on the feet of curling players are also expensive.
    At first glance, the appearance is almost the same as ordinary leather shoes.
    However, if you look closely, the left and right feet of curling shoes are not exactly the same.
    The colors of the two soles are one black and one white.

    .
    The reporter learned that this is because curlers need to slide normally and walk upright.
    Those with black soles are just skates, and the soles are made of rubber; those with white soles are just skates, and the soles are made of plastic

    .

      During the competition, the curler wears the pedals of the skates to push the ice backwards on the kicker, so as to obtain the driving force to slide forward.
    The skates do not touch the ground without decelerating.
    When the athlete needs to stop, only the skates need to touch the ice surface.
    , the small particles raised on the rubber sole of the skates will generate friction, allowing the athlete to stop quickly

    .
    The sole of the skateboard is a skateboard made of plastic, which has less friction on the ice surface and can be skated during the process of wiping the ice

    .

      The ice lane of the curling competition is about 44 meters, which is slightly shorter than the standard swimming lane, and the ice surface is different from that of figure skating and short track speed skating
    .
    It is not completely flat.
    The top layer is covered with specially made tiny particles.
    Athletes can use an ice brush to brush the ice surface to change the friction between the curling and the ice surface, and can also adjust the direction
