Restroom. Obviously life on board a fighter jet is cramped, and there isn't a lot of room to move your body, much less use the restroom. In addition to water, on every flight I carry an item called a pittle pack. As its been stated, its a plastic bag with powder in it that reacts to urine.
Mercury is a metal that is liquid at room temperature. When combined with gold or silver, it becomes viscous, its consistency becoming similar to that of butter. Mercury gilding is the process in which mercury is mixed with gold to make an amalgam that is applied to the surface of an object.hen combined with gold or silver, it becomes viscous, its consistency becoming similar to that of butter.

As shown in the picture of the aneroid barometer, this instrument relies on a sealed, flexible unit which contains air at a fixed volume. As the atmospheric air pressure changes, this membrane expands and contracts, altering the position of a needle on the barometer. Mercury barometers use an evacuated tube, and Mercury rises or falls within this tube as the atmospheric pressure changes, pushing the Mercury higher or lower in the tube.
