Adult visitors can join the public ‘Last Minute’ tour. On a tour of terra mineralia, they will learn everything about Dr. Erika Pohl-Ströher's mineral collection and her beautiful mineral specimens. The tour takes place every Sunday at 10:30 a.m. – on 28 December and 4 January. Additionally, on Tuesday, 30 December at 2:00 p.m.

For families and all curious visitors, the interactive laboratory ‘Research Expedition’ will be open on 29 and 30 December and on 3 and 4 January. Here, students will demonstrate the experiment of the month on the topic of volcanoes. At the volcano measuring stick, you can find out how big you would be as a volcano, and there is a volcano pump and, of course, volcanic minerals and rocks to try out.

The family tour ‘Night at the Museum’ will take place on 27 December and 3 January, both at 6 p.m. Equipped with headlamps and UV torches, participants will search for fluorescent minerals in the dark exhibition.
