Burping liquids and gravity

  1. Jun 10, 2015 #1
    Hello I have a question. When you turn a bottle upside down, the liquid pours out and air pockets rise into the upper part of the bottle, taking the place of the displaced water.
    I'm just curious, if you could reduce the effect of gravity on the bottle, is there a point where the bottle could no longer burp (without reducing the effect of gravity to zero)? Does it not matter because of the difference in densities?

    Interesting question. Offhand I'd guess that at some point before zero gravity the air would no longer be able to break the surface tension and the water would cease to pour out.
