A 50 x 50 x 1 cm Hele Shaw chamber was packed with two sand grades, with sharp interface between them. The chamber was saturated with 10% CuSO4 solution and free evaporation was allowed for 280 days. An image was taken with an automated digital camera every 12 hours. A set of selected images was used to compose the movie. Both evaporation front and salt precipitation along the 280 days can be seen. The results from this experiment promote the conceptual mechanism discussed in this manuscript.
