Hydrophobe and Hydrophile

Hydrophobicity is the property that a molecule repels from the contact with water. You can always see leaves or grass with dews on them – if the leave or grass is hydrophobic, the dew would tend to look like a perfect sphere. And the dew rolls down easily when you gently shake the leave. A hydrophile, on the contrary, likes interacting with water molecules. A water drop on a hydrophilic surface has the contact angle smaller than 90 degrees.
