Sometimes in a science centre or nearby there is one huge exhibit: a planetarium, hosting at least a few dozen visitors simultaneously. How to treat it? Is it a separate place with distinct aims from the rest of the science centre or does it complement the offer? During the session we will discuss different approaches to placing the dome within the science centre. Do we want it to be a place to rest after an exhausting tour of the exhibition or a space for active adventure? In the last case sometimes a living guide is a key factor, and other times unusual equipment can play that role.
