- The goal is for young people to think a little more outside the box.
That you do not just read books and learn in a traditional way, said teacher Emelie Olsson.
The school has invited classes in grades five to eight to visit them.
A total of twenty classes from other schools have visited.
In addition, 800-900 visitors from the public have also come.
Sunday was the last day to visit the event.
