Flight attendant reveals the one common plane habit that is 'heinous, evil and diabolical'

If you want to know how something works on a plane then ask a flight attendant, they'll know what's going on.

They know more about flying than you do so it's worth listening to their advice and learning their ways so you're not the problem passenger everybody dreads getting.

Over the years they've seen plenty of things that'd be considered unpleasant and know how to deal with the ups and downs of travel.

So when they say there's one very definitely 'evil' thing which you must avoid at all costs it's worth listening to the warnings.

It's been named 'the most heinous, evil, diabolical' thing you can do on a plane by flight attendant Cher, who explained just what this evil thing was.

Apparently the absolute worst thing you can do as a plane passenger is put any type of bottle containing liquid in the overhead luggage bin.

It sounds pretty innocuous at first but she had a good reason for thinking it was utterly diabolical.

Speaking in a video on TikTok, she said: "Every single time without fail that water bottle, as soon as we take off, is going to leak all inside the bin.

"Not only does that soak everybody else's bags but the water always picks one person and it'll follow a stream and completely dump out of the bin onto one person."

There is a scientific reason for this, as the plane gets higher in the sky the change in pressure will cause the air in the cabin to expand, meaning that air trapped in bottles also expands and can push water out of what was previously assumed to be a watertight container.

All that water then sloshes around in what is likely a reasonably unhygienic part of the plane, not that there aren't many of those, before dropping on someone to ruin their day.

So next time you're on a plane and take a drink with you don't stick it in the overhead storage.

Either hold it in your hands while you're in your seat or have it in your hand luggage that you've got out with you.

That wasn't the only thing on Cher's diabolical list, as she said that flying while feeling sick took the silver medal.

If you know you're not feeling well then it's going to be worse once you're up in the sky, at which point you're trapped in a metal tube with a lot of people who didn't pay through the nose to be a witness to your vomiting.

Nabbing the bronze medal on this list was 'going to the bathroom during turbulence as a man', and you can well imagine how that'd impact the aim of your urine cannon.
