Experyment Science Centre is Gdynia's hands-on science museum, built around interactive exhibits rather than glass cases. It is aimed squarely at families, but the best installations work for adults too: physics, the human body, everyday technology, and the simple pleasure of pushing buttons to see what happens.
It sits away from the Southern Pier cluster, so do not treat it as a quick add-on to the aquarium or museum ships. It is most useful on a wet day, with children, or when you want a break from maritime history without leaving Gdynia's practical city fabric.
