The demonstrator (100) has an upper tank (20) containing the quantity of deionized water, and including holes (23, 24) in a bottom part (22) of the tank. The tank is located above a sample support (10) so that the water droplets (G-A, G-B) fall one by one through the holes onto a surface of a sample. A deionized water supplying system supplies deionized water to the tank. The system maintains constant water level (N) above the bottom part of the tank, in which the holes possess diameter and a bore profile designed, such that the droplets form and fall spontaneously at regular time intervals. |
