Marking 25 years since the museum opened as an independent institution in 2001, this anniversary programme brings a varied schedule for the day. Live presenters share insights in the exhibitions and at the aquarium, including a session on the mammal collection and one at the aquarium itself, plus a fish feeding and a guided tour of the insect collection. Visitors can watch live insect preparation under a professional microscope, make a button by stamping, and spin a wheel of fortune for goodies.
