# Oh My Glob We’ve Been Pouring Juice Wrong Our Whole Lives

Alright, I’m going to go ahead and admit it: I had no idea how to effectively pour juice.

I’ve probably done it the wrong way since forever. I feel silly now. Thankfully, a crazy Russian hacker has set me straight. No really, that’s his name.

Over the very popular YouTube channel Crazy Russian Hacker, the host shows us lifehacks that are so simple you’d smack yourself for not thinking of them. You’ve been taking your shirt off wrong. You’ve been wrapping your computer charger wrong. And he says that you’ve been pouring juice wrong your whole life. Darnit. He’s right.

Why do cartons of juice glug glug glug in the first place? When the juice is first sealed for sale, the contents inside are at the same pressure as the outside — atmospheric pressure. When you pour the juice out the “wrong way,” the weight of the liquid forces it out of the carton. But when the volume of liquid in the carton decreases, the air bubble in the carton increases. When you increase the volume of a gas without adding any mass, its pressure decreases. Once the inside of the carton is at a lower pressure than atmospheric, the outside has the air pressure to push past some juice and equalize everything — glug, glug. This process repeats itself until the carton is empty.

The “right way” to pour from the carton gets around the problem of pressures. By leaving a section of the pouring hole unblocked, air is free to rush in and equalize, making for a perfect pour. (The same technique applies to motor oil and other similarly shaped containers — that’s why they re shaped that way!)

I can’t believe I never tried this. (╯°□°）╯︵ ┻━┻

This has no place on this site. Utter trash, what is this…huffington post? Jesus.

2. Norman Sword says:

Cartons by design are flexible and thus any slight pressure difference would collapse the walls. Of course you can strive to be as difficult as possible and do the supposed incorrect method. I normally stand on a chair and put the glass on the floor, and squeeze as hard as I can. This quickly fills the glass. Job done!!!!! (makes a bit of mess though)

3. Put the nozzle to the glass and pour it like everyone in the entire freaking world that’s not under 6
does…

4. rob says:

Or you can pour it slower like a normal person

5. Jim says:

Quite a lot of the cartons in the UK have flat tops, so it is just as easy to pour one handed either orientations.

Just amazed I never tried that though…

6. John says:

The ‘right’ way involves using both hands, and bending back the top of the carton? …umm…

7. Megan says:

Orrrr, you just don’t tip the damn carton upside down when you pour. There is a level you can tilt the carton where the glug won’t happen. Not rocket science, and you don’t have to bend the top or turn it over.

• LOL  thats exactly what i was thinking! Pour like a human and you’ll be ok with either side.

• Tom says:

You can also just pour it like a functional adult (not upside down or with the immediacy of removing pepperspray from your genitals) and the air vent is still there. Being a functional adult is the best life hack…

8. Dan Luedke says:

If you got it in your glass it wasn’t the “wrong way”. It’s only wrong if you missed the glass completely and poured juice all over the counter.

• SeventhReign says:

If that is the case … then I’ve still been doing it the wrong way for years.  Granted most of those times involved Vodka … and usually didnt happen until both Vodka and OJ were almost empty..
