Taste of Home spotted this trick on the TikTok channel goldilocks.bears.x. It starts with a demonstration of how most people pour liquid from a carton—meaning you probably hold the container so that the side with the plastic spout is closest to the bowl, cup, or whatever vessel you're pouring the liquid into. This results in your O.J. or 2 percent glugging out in an awkward manner, possibly splattering your hands or kitchen countertop.
You can spare yourself the potential mess simply by tweaking how you hold the carton. If you flip it around so the opening is now on the upper side, your pour will be much smoother. The video below shows how this method produces a steady, splash-free stream even though the liquid now has a longer distance to fall.
