What is Hydrophobic?

Hydrophobic is a property of a substance that repels water. It means lacking affinity for water, and tending to repel or not to absorb water. Hydrophobic molecules tend to be non-polar molecules and group together. Oils and fats are hydrophobic.

Hydrophobic materials often do not dissolve in water or in any solution that contains a largely aqueous environment. Hydrophobic materials are often used to remove oil from water, manage oil spills, and chemical separation processes that require the removal of non-polar substances from polar compounds.

Hydrophobic surfaces decrease corrosion rates, and therefore are used in corrosion resistance. ( Source : https://www.corrosionpedia.com/definition/653/hydrophobic )


I show you how hydrophobic steel balls can form an aerodynamic air pocket that slices through water with almost no drag.
