Which of the floating segments inside the glass capillaries is water and which is air? Water can defy gravity, climb up plants and trees, and even glass, resulting in a concave meniscus. The perfect illusion of the coherent system acts completely autonomous, only influenced and affected by the light breaking through the glass.
Water acts in a magical way when filled into a capillary glass tube, as it floats above of the naturally enclosed air. Despite the openness of the glass tube the by air separated water segments are enclosing themselves. The minuscule water droplets start to evaporate and condensate inside the air regions. The water areas orderly vanish into the atmosphere from top to bottom with time. The microscopic effect can be observed with focus and intrigue many asked questions.
