We Just Learned We’ve Been Pouring Juice All Wrong!

While it may seem strange, there's a scientific explanation. That's because, inside a sealed carton, the atmospheric pressure is the same as outside the carton:

But when you pour with the spout closer to the glass, it's the weight of the liquid that pushes it out of the carton, leaving no room for air flow via the pouring hole.

As volume within the carton decreases, an air bubble within the carton forms and increases — this results in a decrease in pressure. The uneven pressure within the carton and outside of the carton results in the familiar “glug glug” sound, since outside air pushes some of the juice back in. But when you pour the “right way,” there's a small hole in the spout that lets air flow in and out, letting the pressure remain neutral.
