Photo by Dina Litovsky dina_litovsky | Students in Kiev celebrate the last day of school by jumping into the city’s numerous fountains. The "last bell" ceremony dates to the Soviet Union era and is still observed in many post-Soviet cities. The festivities begin just after classes finish but before the final exams. For a couple of days, Kiev turns into a playground for students celebrating the beginning of summer. For more images, follow me dina_litovsky.
