A mixture of water, ethanol and thymol blue indicator is shaken together. The resulting pink foam contrasts with the gold of the bulk liquid, and its decay can be photographed. A second experiment concerns reaction rate measurements.
Components are sulfite, sodium metabisulfite, formaldehyde and phenol phtalein.
The components are shaken together and a sudden color change indicates completion of the reaction. The side of the box facing the camera was treated to be non-wetting. A nylon cloth wick and three SS wicks of different weave are applied to silicone oil and a water-soap solution. The astronaut's description of the rate experiment indicated a unique morphology. One experiment run is executed.
