Kinetic sand in a box as an office toy. Hydrophobic sand (or magic sand) is a toy made from sand coated with a hydrophobic compound. The presence of the hydrophobic compound causes the grains of sand to adhere to one another and form cylinders (to minimize surface area) when exposed to water, and form a pocket of air around the sand.

The hydrophobic soil particle is coated in a wax-like lipid compound [4] with a hydrophilic head is attached to the individual particle and the hydrophobic tail is surrounding the outside of the particle. This hydrophobic tail shields any water from being absorbed by soil particles when many are affected. [2]

The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and to be excluded by water. [ 1 ] [ 2 ] The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes the entropy of water and minimizes the area of contact ...
