Pour some alcohol into the bottle and swirl it around. This process helps to evaporate all the water vapor in the bottle. Use a cutter(with the help of a large one) to cut the cork so that it is half the length. Connect the end of the pump to the cork. Put the cork in the mouth of the bottle and hold it very firmly while a helper starts to scare until it starts to get enough resistance. Then remove the cork and watch the cloud form before your eyes!
