  • Yep it’s not your day.

  • Youre hurdling toward the ground from thousands of feet up, and all you can think is, “So

  • this is it, huh?

  • THIS is how I go?

  • All because I decided to take a little risk, live on the wild side!”

  • Skydiving?

  • Nope.

  • BASE jumping?

  • Negative.

  • You, my daredevil friend, ignored that sign near the airplane toilet warning you to close

  • the lid before you press the flush button.

  • And it pulled you through and spit you out.

  • And, thus, weve come full circle: youre freefalling to your untimely demise.

  • Wait, back up, you got pulled through the toilet?

  • As in, that tiny hole barely big enough for a mouse?

  • ARE you a mouse?

  • Ok, fine, exaggerated a bit on that one

  • unless, you come out the other side all spaghettified?

  • In that case, ew!

  • Or yum?

  • The sound of knocking snaps you back to reality.

  • Someone in there?”

  • Uh-oh, you got lost in your thoughts again, staring down that waterless bowl and wondering

  • if the warning sign was put there to prevent the exact situation that just came flooding

  • to your mind.

  • What else would it be for?

  • Youre no foolyou know this plane is airtight!

  • Every crevice has been sealed to keep the cabin pressurized.

  • Because otherwise, none of us would be able to breathe this high up in such thin air.

  • (Must be a regular here on the Bright Side, I like it!)

  • And what about all those movies showing holes in the fuselage ripping passengers right out

  • of the plane in the blink of an eye?!

  • When you flush the toilet, you open that hole, creating an opportunity for the pressure difference

  • to eject the contentsright?

  • Why else would it be so loud and fast?

  • Ok, let’s back up and tackle this thing one question at a time.

  • Even if you were somehow pulled through that tiny hole, you wouldn’t get spit out of

  • the plane, spaghettified or not.

  • When you flush the toilet on an airliner, the contents don’t just get sprayed across

  • the Earth for everyone down below to, uh, have to deal with.

  • (Grab an umbrella!)

  • That would be gross, harmful for people and the planetand illegal!

  • That umbrella wouldn’t do you much good either.

  • The stuff would be frozen from the cold temperatures at that high of an altitude.

  • (Oh, well, then, take cover!)

  • Hey, that’s actually how planes used to do it in the olden days of aviation.

  • Yep, chuck it out and Geronimo!

  • Fun fact: it’d also be blue.

  • Hmm, pretty sure the stuff that we deposit into commodes shouldn’t be anywhere near

  • that shade.

  • It’s not the waste itself but rather the liquid disinfectant that cleans the bowl with

  • each flush.

  • That’s not to say airplanes don’t decorate the landscape with sewage these daysonly

  • now it’s purely by accident.

  • (It’s also incredibly rare, so no need to swear off ever leaving your house again.)

  • It happens if there’s a leak in the holding tank.

  • The result?

  • What’s been dubbedblue icehailing down!

  • Hellooo?

  • Sorry, pal, but the line’s growing out here!

  • Think you can speed it up?”

  • Spaced out again

  • But if you got pulled through the toilet, you wouldn’t end up hurdling toward the

  • groundyou’d just go to that onboard holding tank that keeps all the waste until

  • it can be emptied.

  • But what if the pilot accidentally empties it right there in the air?

  • OR what if he needs to, like to make the plane lighter in the case of low fuel or an emergency

  • landing?

  • Impossibleit can only be opened from the outside by ground crew.

  • Imagine having that job.

  • They stick a giant hose to the bottom of the plane’s rear and pump the stuff out and

  • into a truck for safe disposal.

  • Hmm, makes me wonder: would you rather have a job like that and make all the money you

  • need, or the job of your dreams and barely have enough to get by?

  • Let me know down in the comments!

  • Anyway, back to our story

  • If it goes to a tank, then what creates that incredible suction?

  • Well, the onboard lavatory system does make smart use of the pressure difference between

  • the inside and outside of the plane.

  • And that’s why it’s so loud when you flush.

  • There’s that holding tank, right?

  • It’s where that big blue sloshy mix of waste and disinfectant hang out.

  • It has a pipe that leads to a hole in the plane.

  • Don’t worry, it’s supposed to be there!

  • So, that means the pressure inside that tank is what it should be at 35,000 feet up.

  • But remember, when you do your business, the cabin has been pumped with a bunch of air

  • so that everybody can breathe.

  • When you flush the toilet, it opens a sort of flap.

  • Because high pressure will always go where its lower when given the chance, the immense

  • air pressure in the cabin pushes whatever’s in the toilet down to the holding tank.

  • And, boy, does it push it!

  • At about 300 mph, mind you!

  • Hello, sir?

  • This is Tammy from the crew.

  • A lot of people waiting and worried out here.

  • If you don’t open the door soon, I’m going to have to open it myself.”

  • Yeah, one second!

  • Justhaving a bad reaction to the chicken!”

  • Even at breakneck speeds, the suction isn’t enough to pull you through.

  • It’s not even enough to push the compressed air out of the lavatory itself since there

  • are vents to the room, and the doors aren’t airtight.

  • Plus, that flap isn’t open long enough to make any difference.

  • You push the flush button, the flap opens, the blue cleaning stuff washes yourdeposit

  • away, and it closes back up.

  • It also isn’t enough to suction you to the toilet seat if you happened to be sitting

  • on it when you flush.

  • Technically, it could if you somehow managed to create a perfect seal.

  • And everybody mentions as proof the samewoman who got stuck to a toilet during a flight

  • 10 years ago.”

  • But that’s almost impossible since the toilet seat itself has ridges under it.

  • Meaning, when it’s down on the rim of the bowl, the ridges hold the seat up and allow

  • air to move through, probably like the toilet seat you have in your own home!

  • But if this system depends on the pressure difference, does that mean the toilet won’t

  • flush if youre on the ground, landing, or taking off, where the pressure is equal?

  • No, you can still use the bathroom at these times, but the system has a motor to create

  • that vacuum.

  • Granted, it requires power to work, so that’s why they usually ask you not to head to the

  • lavatories until youre at a certain altitude.

  • That, and things get shaky when youre taking off or landing.

  • Passengers could fall down on their way to the restroom, or if youre already in there,

  • then youre surrounded by lots of things you can bump your head on in that tiny space.

  • Well if you can’t get pulled through or suction-cupped to the seat, then why are there

  • these warning signs telling you to close the lid before you flush?

  • A couple reasons.

  • For one, it’s deafeningly loud and disturbs other passengers.

  • But more importantly, it’s something you should do even at home because of what’s

  • calledtoilet plume.”

  • And that, my friend, is bacteria-infested microscopic particles that spray up and around

  • a 10-foot radius each time you flush the toilet.

  • So, if youre one of those people who keep their toothbrush on the bathroom counter,

  • you might wanna give it a cozy new home in the medicine cabinet.

  • As for that closet-sized airplane lavatory, you know that stuff would be on EVERY surface!

  • Sir, this is your final warning.

  • I’m so sorry if youre not feeling well, but others are growing impatient.”

  • Be right out!

  • Just gotta wash my hands!”

  • Oh, that reminds me!

  • (Better make this quick or the whole brigade is going to come crashing through that door…)

  • If there’s one place thatll spit you out the back of the airplane, it’d be the

  • tap system!

  • Ever wondered what happens to the water that goes down the sink?

  • Well, there’s your answer!

  • It gets heated up before it’s released so that it doesn’t freeze and stick to the

  • plane.

  • That’s not good since it would add extra weight.

  • And in the aviation world, extra weight equals more fuel burnt, which means more expense.

  • Weight and expense also play a role in why that water shuts off so quickly while youre

  • washing your hands.

  • It’s because the plane can carry and, therefore, only has so much of it.

  • It comes from a tank under the cabin.

  • No worries, it’s not the one holding all the toilet soup!

  • So, I guess if I could shrink myself down to the size of an earring, I could get washed

  • down the drain, shot out the back of the plane, and, once again, be freefalling back down

  • to Earth.

  • Luckily, that’s just not poss-

  • Sir, I’m sorry to barge in like this, but I’m going to have to ask you to take

  • your seat.

  • Thank you for understanding.”

  • No problem, I was just on my way out!”

  • Ugh!”

  • Finally!”

  • About time!”
