Abstract
In some examples, a method includes applying a negative pressure to a gas-filled volume through a vent. While a pressure in the volume decreases, the method draws a gas out through the vent and moves a liquid into the volume. The volume is filled with the liquid so that one side of the vent is covered with the liquid and the pressure in the volume increases up to a specified point.
