At the Makerspace of the Humboldt-Bibliothek, families try out how virtual worlds can be created. Activities include tinkering with electronics, programming robots, making stop-motion animated films, and cutting colourful masks with a laser cutter. The Tüftel-Saturday is aimed at families with children aged 6 to 12, and no registration is required.
