Sand art is the practice of modeling sand into an artistic form, such as a sand brushing, sand sculpture, sand painting, or sand bottles.

A sand castle is a type of sand sculpture resembling a miniature building, often a castle.
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.
