Condensing

The kids spent a long time condensing the snow into a big snowball.

A large curved retort was boiling furiously in the bluish flame of a Bunsen burner, and the distilled drops were condensing into a two-litre measure.

In Russia, where experiments on a considerable scale have been made with condensing, the railways have the considerable advantage of a loading gauge 17 ft. high (the biggest in the world), as compared with the British 13 ft. or slightly over.
