At 4:45 we went by car to a parking lot where we met the owners of the hot air balloons. There we saw a clip about the history of hot air balloons. Unfortunately the weather was bad, so we couldn't make the balloon trip, but it was good enough to blow up one of the balloons and to have a small flight with it. After this we rolled up the balloon and we went to Gruyère, where we had a picknick breakfast near the chocolate factory Callier. We saw a movie about the Callier factory while we waited for our turn to have a tour through the factory where we saw how the chocolate was made and where the ingredients came from. We could also taste the ingredients and in the end of the tour, we learned how to be a real chocolate taster by tasting a lot of different chocolates. Then we returned to grenchen where we had a late lunch/early dinner, raclette. After that some of us went to grenchen for some shopping. In the evening we ended our day with a beautiful firework show in Biel.
