Hard Sphere Simulator
A Hard Sphere Simulator (HSS) is a mechanical model for demonstrating microscopic features and phenomena such as atomic arrangements in a crystal lattice and corresponding defects in the lattice at the macro-scale; hence, it is a potential learning tool for students. Here, we describe the construction of an HSS, using polymer gunshot balls as hard spheres. Using this HSS, we demonstrate material phenomena such as phase transitions and formation and movements of defects. We also show that, by carrying out Fourier transformation on the images obtained from the HSS, one can obtain the diffraction patterns of these structures.
