Each team chooses to represent a country and provides its own costumes (homework as a teaser). Optionally we can also provide costumes if necessary.
On the day itself we travel around the world, from country to country... Each country has a practical task to fulfill, knowledge questions to answer, a workshop and a tasting session. During the various missions the countries can raise their joker that they gained during the tastings/knowledge questions.
This concept can also be used as a travel through time where the participants travel from prehistoric times to the 21st century and also complete all their missions.
