• Ground floor is for kids: the science playroom and the toy gallery, where displays sit at kid height
• Family ticket covers parents and their children in one go, cheaper than singles once a child is 7 or older
• Groups book ahead, since the museum does not promise entry to unannounced groups, so call before a class or party outing

The museum fills the 1928 building of Serbia's first public power station, in Dorćol. On the ground floor, a science playroom lets kids feel centrifugal force, test their balance and puzzle over optical illusions, and a toy gallery shows over 150 toys from 1920 to 1970 at kid height.

The Aleksandar Despić gallery holds 400-plus objects, from steamships and old printing to the first Serbian-made computers and Tesla's induction motor.
