ABSTRACT:
A three-dimensional model of molecular structure comprises plastic modules and their connecting elements which are made as cylindrical rods whose entire surface, as well as the mating surface of sockets of the modules, is provided with easily curved projections alternating with depressions of the same shape. To assemble or disassemble said three-dimensional model use is made of a device, whose jaws each have a wider portion to hold the module and are bent, and the inner surface of the jaws being provided with wedge-like projections to facilitate disassembly of the modules.
