The idea of this type of exhibition was born a few years ago former as a mean to support various educational initiatives in favor to schools nearby our area and latter to make some spaces of the Institute of Biomolecular Chemistry (ICB) more welcoming. With this in mind, Francesco Castelluccio (during the Institute direction of Dr. Guido Cimino) started to collect a series of small instruments and objects from our daily work, no longer used, to be exhibited in these spaces. Over time, the subsequent directions of the institute have also encouraged this side activity.
