The museum displays over eleven thousands of intellectual items from 130 countries around the World. All items are classified into 15 subcategories in order to create a friendly environment for visitors. The guide is available for every visitor with an explanation of the exhibits. Most of the displays of the museum represent various branches of sciences in simplified form by toys and puzzle games.
