Gases that are relatively insoluble in water are collected by water displacement. The gas pushes the water down and out of the water-filled gas-collecting vessel. The gas-collecting vessel (generally a flask or test tube) is first filled with water, covered with a glass plate or plastic wrap (no air bubbles must enter the vessel, and then inverted into a deep pan or tray half-filled with water. The glass plate or plastic wrap is removed, and the tubing from the gas generator is inserted into the mouth of the gas-collecting vessel.
Vessel" is a terms used in art, to describe a kind of sculpture that is formed like a container. In everyday life, "vessel" has wonderful connotations too.
