Actionbound. Spice up your party after the youth exchange with some treasure hunting. You need to create an account on Actionbound and build the content there. It can be a quiz with multiple answers or a location of some special place linked to your youth exchange topic. You can hide some treasures outside for people to do some treasure hunting and get more interested in the topic of the exchange.
