Hydrophobic sand

Hydrophobicity is a property of molecules denoting the "tendency" to avoid contact with water, the disinclination to wet and mix with water. In everyday life, the manifestation of hydrophobicity can be observed in the behavior of oil with water.

A simplified mechanism of this phenomenon: water consists of polarized molecules (roughly speaking, a magnet with two poles: plus and minus), so it mixes well with other polarized molecules, while hydrophobic molecules are not polarized (so simplifying: the magnet has nothing to cling to).

🌽A visual demonstration of Stokes' Law in corn syrup

Stokes' Law, named after George Gabriel Stokes, describes the relationship between the frictional force of a ball moving in a fluid and other quantities (like the radius of a particle, the speed of a particle). If a ball or body moves in a liquid, it must overcome the force of friction.
