Kostel svatého Ignáce Velikonoční mše - Easter Mass, people leaving the church

The end of a worship in the church of Saint Ignatius at the Charles Square. Last evening before Easter during the Mass the bells sounds and after they get silent -"fly to Rome". The sound of bells until the Great Friday vigilia is replaced by clappers and rattles. During the Mass celebrated by the Jesuits, whom the church belongs was rattling discreetly suggested by two boys rhythmically klicking during the procession to the altar.
