Cool stuff!
I googled a bit and found this:
Hydrophobic sand is ordinary beach sand coated with tiny
particles of pure silica, which have been exposed to a
special chemical treatment vapors of a silicon compound
called trimethylhydroxysilane, (CH3)3SiOH. When the beach
sand grains are exposed to trimethylhydroxysilane, a
reaction takes place resulting in the formation of water and
in the bonding of the trimethylsilane compound to the silica
particles. Following this treatment, the exteriors of the
sand grains contain groups that are insoluble in water or
hydrophobic / water hating.
Any questions left?
