Dry water in a wet dungeon? An isolated H 2 O molecule has been trapped permanently inside hydrophobic C 60 (see picture; green C, white H, red O). The endohedral fullerene H 2 O@C 60 was synthesized by opening, filling, and reclosing the carbon cage. The incarcerated water does not alter the structure of the cage, but it confers an appreciable dipole moment to the new entity with its intrinsically apolar carbon sphere.
