'Ceci n'est pas une bouteille...' was not the title of a famous painting by René Margritte but the title of a small upcycling competition for our pupils from the second year. The idea was to make somthing new from an old plastic bottle. The inventions of our pupils were great: a piggy bank, a fun game, a self-propelling car, a docking station, a ship,... all made from scrap plastic!
