Curling athletes' rubber and plastic "boots" light up Beijing Winter Olympics with dazzling Chinese wisdom

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
.

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

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 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
