The exposition is composed of amusing objects, mostly toys (property of the Physics Department), which are lent together with explaining files. More than seventy different expositive units may be observed, each showing paradoxical and interesting aspects of physics. The units are arranged following the standard taxonomy for this science: mechanics, optics, astronomy, electro-magnetism, thermodynamics, chemistry, light, sound and so on.
From a psychological point of view, toys appear to be particularly effective in pointing out the basic concepts of physics, exactly because they have not been ideated for that purpose. On the contrary, laboratory items, explicitly born to demonstrate the physics principles, are less convincing because of their congenital characteristic of "special" objects.
A further advantage of this exposition is its interactive component . Most of the exposed toys may be touched and tested by the visitors, who are thus more involved. To the operative aspect, it is then associated the didactic one: a person touching and activating any device is nearer to science than one only observing.
