Extract
The tendency of the air contained in a soap-bubble is to expand in bulk, while that of the film is to contract in surface. Hence it becomes a curious question to decide whether both of these tendencies are not satisfied when two or more bubbles unite into one.

where T is the contractile force of the film.
