Abstract

Many descriptions of solid-state structures begin with close packing of hard spheres in three dimensions. In traditional presentations, the three-dimensional structures are built up from two-dimensional sheets of close-packed spheres. This model focuses on the two-dimensional sheets, which are spontaneously formed from cereal pieces. The structure of the cereal rafts can be presented with an overhead projector.

      This paper describes simple methods for demonstrating spontaneous assembly of visible particles to illustrate topics such as the thermodynamics of crystallization. The assembling units are polymer tubes--portions of soda straws or connector bonds from ...
