Problem M. 360. (May 2016)

M. 360. Carefully place a water drop to a dry horizontal plastic sheet. Tilting the sheet, slowly increasing its angle of elevation, at some critical angle the water drop suddenly begins to move down the slope.

Measure how the critical angle depends on the mass of the water drop. Investigate the phenomenon in case of different types of plastic sheet.
