The subjects of this project were droplets of saturated aqueous solutions containing various inorganic salts (e.g. table salt, sodium sulfate etc.). The evaporation of water initiated the crystallization processes inside the droplets, which were captured by time-lapse photography.

From Tsinghua University Press and University of Science and Technology of China, filmed and edited by Yan Liang, this is Crystallization 2, a 4K macro time lapse film. For more imagery from the chemistry education project, visit PetaPixel and The Beauty of Science.
