Fractal Aggregates in Tennis Ball Systems
Sabin, J.; Bandin, M.; Prieto, G.; Sarmiento, F.
Physics Education, v44 n5 p499-502 Sep 2009
We present a new practical exercise to explain the mechanisms of aggregation of some colloids which are otherwise not easy to understand. We have used tennis balls to simulate, in a visual way, the aggregation of colloids under reaction-limited colloid aggregation (RLCA) and diffusion-limited colloid aggregation (DLCA) regimes. We have used the images of the cluster of balls, following Forrest and Witten's pioneering studies on the aggregation of smoke particles, to estimate their fractal dimension. (Contains 5 figures.)
