 Although that's glass bottles. See, I don't know if the squeezing, because she actually squeezed the soda bottle. I don't know if that has to do with releasing the carbonation somehow, because you can't squeeze, obviously, a glass bottle. So I'm not sure if it's going to work so well with a beer. And the cup was pressed over the top of the bottle. Did that prevent extra air from going in or flowing in or something? I'm not sure. Definitely above our science abilities. Agreed.
