air ball

"The air ball," I moaned, pretending to regain consciousness slowly.

This vast and splendid place had been converted into an open air ball-room.

Nothing would be pleasanter than to read in a well-written book of an open-air ball that took place a century ago.

An obsession could be pricked like an air-ball with the right weapon at the right moment.

The Parnass's complacency collapsed like an air-ball at a pin-prick.
