"Hold still," said the boy, and suddenly sand fell away under my fingers, making a handhold.

Even the dry sand was falling back into the depressions their feet had made.

The sand is slowly falling through the hour glass.

The sand fell on the face of a woman and trickled down around her head and neck.

Incoming sand fell through a grating in the floor, into a receptacle below.

The sands fell away to reveal the translucent image of a woman.

The seconds were running out, the sand falling ever faster through the thin glass throat of the timer.

Then the sand fell back with a heavy thrrrrap.

But I pulled my arms down and the sand fell in around them.
