I thought this was interesting. Now I know why those flight suits are so bulky.

...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. The powder and urine mixture then turns to a jelly that helps prevent spillage, and the entire bag then rolls down and seals on itself...
