851. Does blowing on or waving a developing Polaroid picture actually speed up its development process? — PS, Columbus, OH
The speed of the development process is determined by the diffusion of molecules within the developing film and by the rates at which they react with one another. Both processes, diffusion and chemical reactions are temperature sensitive. If blowing on or waving the film manages to increase its temperature, then diffusion and reactions will both speed up and the development time will decrease.
