The can was light, might only have held air for all he could tell.

However, air does not hold heat very well, and these systems aren't recommended for residential use.

The air held the heat as it always did.

There was a second of silence, the air holding its breath.

One person directs the air and someone else holds the brush.

The wind had died down and the clean air held the promise of spring.

The air held no traces and, even if it had, the wind would have blown them away.

The air held the cool, familiar scent of the trees.

Beyond it, the air held the bright, reflective quality of sky over water.

The air held a hint of the winter to come, but the sky was without a cloud.
