I have a beer bottle full of liquid with viscosity, density and surface tension similar to that of water - for the purposes of this experiment, it’s a liquid - hypothetical if necessary - that will not boil at room temperature in a vaccum.
I’m holding this bottle in my spacesuit-gloved hand in a vaccum chamber on Earth - there is as near to a complete vacuum as possible in the chamber.
I invert the bottle over a glass held in my other glove. What happens?
I think what happens is that the water pours out of the bottle in a fairly orderly fashion, and an empty space appears above the remaining liquid in the bottle as it goes, but without the necessity of any bubbles glugging in through the bottle’s mouth to create that empty space as I pour. Am I right?
