Abstract
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 certain chemistry model kits--floated on water.
Supplement
Supplemental materials describing a wide variety of assembling units and their resulting structures are available.
