During the carnival, it is traditional, especially for young people, to hurl talcum powder at each other until they are completely covered with it. In the past, young men used this game to seduce girls. Although the method of courtship has changed in modern days, the tradition of throwing powder on one another without distinction of gender or origin continues. (Photo by Jon Nazca/Reuters)
