European awareness by live performing arts !

Hello! I'm working with a group of 6 boys and 6 girls from 14 to 17 years old. We're looking for one partner for next summer! The group is wondering about Europe. Their reflections : we are all europeans but what does it really mean? Even on our country scale, there is a lot of cultural differences, for example between people from the North and people from the South, sometimes even between two neighboring regions, so what makes us european and how can we know if we're european - except our ID card? What do we have in common? What difference do we have ? Why do we have sometimes stereotypes about the others? Help us to become european citizen !!!
We want to use live performing arts (theater, dance, street arts, music, ...) to share nice moments together and promote our reflections because we can see around us a lot of adults who are concerned with this topic !
We'd like to organize this project in two parts. We would prefer to come first in your country and to host in summer 2018.
We haven't any preference for the partner's country, the most important thing for us is to built the project with a group of the same age than us, and spend good time together!
