tetrapak lifehack

[mindstalk]

So there's this kind of tetrapak, pure rectangular with spout on top:

When pouring into a cup, I find the natural way is to pour with the spout on the bottom. But this result in a "glug glug" burst of liquid, and splashing. Turns out I get better results if I hold it so the spout is on the top. (That is, the side the spout is in is held down, but the spout itself is at the top of that side.)

Thing is, with the natural way, the liquid covers the whole spout. And... there's no other way for air to get in. So liquid exits, and leaves a vacuum above it. Eventually air pressure punches up, and "glug glug splash". Held the other way, most of the liquid is below the spout, you tilt it enough so some pours out, and air can enter naturally over the surface of the exiting liquid.

Milk gallons have their spouts on top too. But in the middle of a very small surface, so you're more likely to hold the gallon so as to not cover the whole hole.
