Construction
Sand grains will not stick together unless the sand is reasonably fine. While dry sand is loose, wet sand is adherent if the proper amounts of sand and water are used in the mixture. The reason for this is that water forms little ‘bridges’ between the grains of sand when it is damp due to the forces of surface tension. However if too much water is added the water fills the spaces between the grains, breaking down the bridges and thus lowering the surface tension, resulting in the sand being able to flow more easily and the structure collapsing. According to the BBC TV programme Coast, the ideal ratio is eight parts dry sand to one part water, (though this may depend on the type of sand).
