At this participatory weekend with KATE e.V., children build, craft, tinker, solve puzzles, make music and play while exploring children's rights, nature and sustainability. Activities include an upcycling workshop, a zero-waste trail, building with giant LEGO bricks and designing cities with regular LEGO. On stage, Rotonda Teatro performs the clown theatre piece “Britta, die kleine Ratte”, and the band Ich & Herr Meyer plays music about taking action for a fairer world.
