Abstract

A method of enclosing liquids including the steps of encapsulating a first material within a second material to produce a capsule, locating the capsule in a liquid material to which the second material is permeable, and providing a liquid-enclosing capsule by allowing the liquid material to pass through the second material and thereby to be enclosed by the second material.
