Flushing The Toilet With The Lid Up 💦

- Researchers at the University of Colorado Boulder, wondered if they could use lasers to visualize this aerosol plume, and measure the speed and trajectory of the particles.
They set up green laser beams over a commercial toilet without a lid, positioned two cameras a few feet away, dimmed the lights and flushed the toilet.
The lasers illuminated the tiny particles ejected by the toilet, allowing the scientists eyes and the cameras to clearly see the resulting spray.
The toilet they used in the study, was a brand new clean commercial toilet, filled only with tap water.
Airborne particles ejected from the toilet traveled at speeds of up to 6.6 feet per second and reached 4.9 feet above the toilet, smaller particles measuring less than 5 microns, hung in the air for more than a minute.
Aerosols can transmit infectious diseases including SARS-CoV-2, influenza , norovirus and other viruses, which have been shown to survive on the toilet bowl surface for several days.
Thanks for watching.

Congratulation! 🎉
That settles it. I'm not flushing anymore
That's the lesson I took away from this video too. :-) Not worth the risk.
@@RatKindler I stopped flushing years ago, I just let the next person do it :)
@@WonderWorldYTC It then becomes a whole chain of "I'll let the next guy flush", then the poor sod who chooses to flush receives a spray which is the product of 3 years of use without flushing.
I've developed a technique where I can get the toilet to flush more slowly by *gradually* pushing down on the handle as slowly as possible until it goes down. I don't know how much it helps, but I no longer feel water splashing on my butthole when I utilize this technique!
@psythik ew why would you flush when your butt still on the toilet, specially after watching this 💩☠️
I saw a news segment years ago on something like 20/20, where they used some particles that glowed under UV light. They were able to show how the particles shot up out of the toilet and landed on basically every surface in the room. I haven't been able to find that episode again, but I have seriously hated public restrooms ever since, especially if other people are in the bathroom with me.
fr I first saw the episode when I was like 9 and my mom always wanted to go to the bathroom with me on road trips and stuff if it was one stall or a handicap and I hated it bc of this episode.
That's really funny when you said 'or flush and run like hell'🤣😂 It's ok mate...I will close the
lid and flush it😁😉
Nowadays so many Public toilets don’t have lids at all & so many are automatic can’t even get your pants up to be able to run like hell 😭
Is there a link to the study? I'm curious the mechanical differences between a commercial toilet versus a consumer grade toilet.
I would imagine a massive difference between a low flow toilet and the jet engine they have in an airport bathroom
I always flush with the lid down since I watched the Mythbusters episode on fecal particulates nastiness
hahaha the epic music timed with the flush was great.
as I was editing it, I was thinking, who the hell would put epic music to a toilet flush, but it kind of worked :)
Learned this in home-ec class in high school. Cross-contamination and the importance of washing your hands after the bathroom or to always do your bathroom business before or after never in between.
Running like hell with automatic toilets would be difficult, my pants aren’t even up yet.
That bgm sounds like something that's used for nature montages.
How about test on a normal toilet that doesn’t have the power of a fighter jet.
I think the newer toilets flush straight down and don't have this issue. The new kholer ones.
Thanks for the video !
I will live in an abject state of horror when I next enter the bathroom lol
flushes toilet victory music starts
broo I forgot about this channel it’s a refreshment
oh thanks mate
@@WonderWorldYTC no problem, although not sure I’d thank me if I said I forgot about it; took a while to hop back on CZcams after a wave of bad recommendations
Every public restroom 🤮
Lol your home toilet as well
@@ejlynn6797 Home toilets have lids
I hate using public toilets. As a (retired) medical professional, I know more than most about how unsanitary using one can be.
I found wonderful, and very large toilet seat covers on Amazon. They're not expensive, but they cover the seat fully, and hang very low on the outside of the commode, too. They aren't flushable, but if you grasp them on the side that touches your upper thighs, then ball it up, you can get them to the trash can without touching the toilet seat side. Just wash your hands for 20 to 30 seconds after throwing them away. No, you can't get an STD from a bare toilet seat, but think about sitting on a seat where many people's bare thighs have been on that seat, PLUS the urine and fecal matter on the seat after so many flushes🤢🤮. Please buy toilet seat covers and use them!!! There's a lot of them to choose from: plastic ones that just cover the seat - very cheap - on up to full coverage of the seat that hangs almost to the floor.
That's why I put the lid down and other than my son, I don't know anyone else that puts the lid down.
So u put the lid down how many times are u supposed to wash your hands after touching a toilt seat.
It doesn't surprise me as when i stood in front of a flushing toilet i felt something splashing my leg so i washed my leg
"Every time you brush your teeth there is a little bit of shit on the brush
Skeletor will return next week with more disturbing facts"
Do you know what happens when you flush with the lid down but there is a clog? You don't out about it until you're standing in floating $hi+.
0:17 - What are you doing dude LMFAO 🤣Infecting a good phone. All of the pathogenic mists will seep into the iPhone's microphone, earphone and button crevices.
I did NOT need to know this😂😂😂😂
Is this the real reason dinosaurs are extinct? Or did their short little dinosaur arms stop them from wiping and flushing, thus setting up a cataclysmic environmental and public health disaster that wiped them out?
..............
you’re onto something brother tim!
ur totally right man i was just thinking this
@@keezusidkwhat? no way! me too!
After a few flushes, you can look at the toilet cover if you've kept them closed. You'd spot some droplets right there!
Commercial toilet!!!
THIS 100%. *Most* toilets at home don’t mix enough air and are not fast enough to make this sort of a mess.
and this is why I will now be using seat covers 💀
You weren't using them before 😂
That explains why my arse get soaked whenever I do a courtesy flush. 🤢 I had never come across the term before I saw (or rather heard) it on an episode of "House".
Well, I gotta clean now
Earlier research showed that air passing under a closed lid is accelerated by a venturi effect that spreads the aerosol much further!
The Mythbusters did this experiment years ago, over a decade.
Aw man, I'm gonna need a hazmat suit next time I use a rest stop,.
Even after watching this. There's no way my wife will put the lid down, ever. She just doens't do it, it's like it's only there when she needs to put it up.
What do you do if you’d family thinks this is totally fine and flushes their fences all over your bathroom? I can’t seem to get it through their brick block heads.
I would make sure my toothbrush & towels are kept out of the bathroom
I've had the exact same problem for about 4-5 years now and I still have it, it sucks.
Spray desinfectan before flush.
Run like hell🤣
Pink Floyd
Urine Therapy
probably don't want to know what air is made of.
They didn’t test it with the lid down though
Lol what do you think happens when you flush that thing without a lid on?
Bro and i use a toilet which requires buckets to flush 😭😭😭
But then even toilets at home, with the lid down, its still all over the seat 😢 i need seat covers at home now too
You could (in theory) design and 3D print a ring that fits snugly between where the seat and lid meet so then nothing sprays on the seat and only the bottom of the lid and the protective ring, but then you just have to really make sure that you don’t lean backwards while using the toilet lol
Plz make Vegeta ultra ego action figure
Imagine when you turn on the ventilation fan, how far the yucky stuff would spread...
Thats a powerful flush lol its like Niagara Falls lol 😆 did you see how wet the seat was 🤭 that was a CRAP test 💩
But there’s no evidence they’re using that toilet the spray seems to happen no matter what 😊
Cat food near the toilet? You realize when you flush the toilet water particles and “other” particles spray everywhere?
I'd like to know what kind of toilet they use because I did this and I saw nothing
You had Lazer beams set up in your bathroom?
The whole point is that these particles are too small to see with the naked eye.
@@thomaslove6494 I have a whole bunch of lasers so I saw this so I decided to do it
Theres so much water on his lid, thats just not realistic at all lol
Why no cool videos of what happens when you flush with the lid down? Isn't it like putting your finger over a hose to more forcefully direct the spray?
This is why the "courtesy flush" is a no go for me. Sorry.. Especially on Wednesdays.
Taco Tuesdays and all......
Weird cause my parents always said keep the lid up so you can make sure everything goes down... Kinda thinking 😂 about therapy now. 😢 💬 🤔
That’s just water spraying
This is some important shit right here.
Great video, but I *really* shouldn't have watched it... 🤢
I hear you lol
I will like to flush and run like hell
Colorado administration must have been laughing their asses out when they found out this lab needed funding for this research
I am still alive and healthy.
I try to flush and run. Sometimes backwards..this the tit we learned on Oprah Winfrey show
The pathogens are still going to be transferred when the next person touches the lid to open it...or the flusher...or the toilet paper. Hand sanitizer stations in the stalls should help that IF ppl would use them.
Never mind asking ppl to use hand sanitizers, it would be great if ppl washed their freaking hands after dumping or peeing. 🤢🤢
Are they using airplane toilets? How about an actual toilet regular people use?
I have a few concerns, if this video is legit, and to me it looks and sounds, legit.
When you really think about it,
THIS IS KINDA GROSS!
Consider this.
Most hospital public restroom toilets that I've used ... DO NOT HAVE A TOILET BOWL LID/COVER. And think, who are the most likely people using these public restrooms in hospitals? Visitors that have just gotten out of a very sick patient's room. Maybe some staff or workers of the hospital that don't always wash their hands that well nor do they use alcohol gel. And now they're in the public restroom using it, before they leave for home. That's after working with patients that had really bad GI problems...
If this is true, then WHY DON'T MOST PUBLIC RESTROOMS IN HOSPITALS HAVE LID COVERS? ?
What
I knew it 😂
The real reason why aliens don’t want to visit us…
Oh, god. I can see it now. A public restroom mask mandate.
yep looks like a perfect opportunity for the elites to grab control of our civil liberties yet again lol
Eww Eww Eww Eww
Yep, disgusting!!
What you're saying is, it's in my lungs. 🫁 🫠
Perfume De Toilette Spray is in your lungs 🤣
... and it's probably on your tooth brush as well.
