Glug glug glug. When you pour a carton of juice the typical way, the juice tends to gush out, at least if you pour it quickly. There’s a better way to avoid the whole mess: turn the container upside down.
The gif below posted on Boing Boing demonstrates the difference.
Boing Boing commenters also note that this applies to any carton container with a screw cap, such as motor oil.
Member catgrin explains what’s happening:
It’s a closed container with a small spout. Pouring liquid rapidly enough to to block the spout creates lower air pressure inside of the container. Air wants to rush in and fill it back up to equalize the pressure. So, the second it gets a chance to do so – WHOOSH! and GLUG!
To stop this from happening, just pour at an angle and rate that leaves an air gap at the top of the spout.
Chalk this up to another one of those things we’ve been doing all wrong.
