Hlo friend here's your answer,
Take a plastic bottle and add some boiling water in it. The steam coming out of the water will expel most of the air inside the bottle.. After about 1 or 2 minutes, close the cap tightly on the bottle and pour some cold water on this bottle. The steam coming out of the water will expel. Hope this may help you friend. PLEASE MARK ME AS BRAINLIST..
