- Magic_sand abstract "Magic sand, Moon Sand, Mars Sand, Space Sand, Sqand or Aqua Sand is a toy made from sand coated with a hydrophobic compound. The presence of this hydrophobic compound causes the grains of sand to adhere to one another and form cylinders (to minimize surface area) when exposed to water. As soon as the sand is taken out of water, it is completely dry and flows freely.These properties are achieved by covering ordinary beach sand, which contains tiny particles of pure silica, and exposing them to vapors of trimethylsilanol (CH3)3SiOH, an organosilicon compound. Upon exposure, the trimethylsilane compound bonds to the silica particles while forming water. The exteriors of the sand grains are thus coated with hydrophobic groups.Magic sand was originally developed to trap ocean oil spills near the shore. This would be done by sprinkling Magic sand on floating petroleum, which would then mix with the oil and make it heavy enough to sink. However, due to the expense of production, it is not being used for this purpose. It has also been tested by utility companies in the Arctic areas as a foundation for junction boxes, as it never freezes. It can be also used as an aerating medium for potted plants.Magic sand is made in blue, green, or red in colors but appears silvery in water because of a layer of air that forms around the sand, making it unable to get wet.Earliest reference to waterproof sand can be found in a 1915 book called The Boy Mechanic Book 2 put out by Popular Mechanics. The Boy Mechanic states waterproof sand was invented by East Indian magicians. The sand was made by mixing heated sand with melted wax. The wax would repel the water when the sand was exposed to water.".
