This video from the German BioImaging Team Training and Knowledge Transfer showcases members' contributions to the WDR "Türen auf mit der Maus" event. This annual initiative gives children the opportunity to look behind doors that are usually closed to the public, with a different theme each year—for example, the 2026 theme, "Kleine Wunder entdecken" ("Discovering Small Miracles"). The video aims to provide insight into how microscopy can be presented to children during this event and to encourage more people to contribute to this outreach event.
