description Analyses of the Apollo-Soyuz science demonstrations on chemical foams and liquid spreading are presented. The chemical foams demonstation showed that aqueous foams and gas/liquid dispersions are more stable in low-g than on the ground. Unique chemical reactions in low-g foams and gas/liquid dispersions are therefore possible. Further ground tests on the formaldehyde clock reaction led to the rather surprising conclusions that surfaces can exert a nucleation effect and that long-range surface influences on chemical reaction rates are apparently operative.
