ABSTRACT:
A molecular model has a center made up from two relatively pivotal parts which are angularly movable between predetermined angular positions. The parts are relatively unstable when not in such angular positions. Atomic valency bonds in the form of elongate flexible members extend from the pivotal parts and have at their free ends couplings which engage another like coupling of another flexible member or another center part. The couplings are identical and each comprises both a projection and a socket or in one embodiment a magnet presenting at an end surface, both a North and a South pole.
