• Dim deep-sea rooms in Tajemnice głębin can feel intense for younger kids, so talk it through before going in

A hands-on science center in Gdynia where kids test the exhibits instead of reading about them. Magnesto has 10 magnetism stations, including an electromagnetic accelerator and magnet races. Tajemnice głębin shows over 40 models of deep-sea creatures, from vampire squid to glowing jellyfish. Other halls cover the human body, water, health, physics and nature, and family workshops run alongside the exhibitions.
