Water is easily the most frequent liquid on our planet, vital to all life forms. It will be the dispersion medium for all biochemical reactions of the living process and requires part in several of such reactions. Regardless of the chemical simplicity of the water molecule, its physical properties are quite remarkable -- one might say weird! -- and have been a major research topic for many years. Many experiments give great insight into the structure and dynamics of water, but these often require the resources of a major research laboratory. In addition, some must take place under extreme conditions, such as those leading to superheated or supercooled water.
