Flushing The Toilet With The Lid Up 💦
Ғылым және технология
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.

This is my last video for the year, as I mentioned in a community post, I am getting married early January and I will be taking the month off to finish organising everything and having my honeymoon. So I would just like to thank everyone for a good year and I hope you have an awesome Christmas and a Happy New Year.

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.

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
hahaha the epic music timed with the flush was great.

I always flush with the lid down since I watched the Mythbusters episode on fecal particulates nastiness
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.
Thanks for the video !
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.
That bgm sounds like something that's used for nature montages.

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.

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.
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+.
So u put the lid down how many times are u supposed to wash your hands after touching a toilt seat.
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.
After a few flushes, you can look at the toilet cover if you've kept them closed. You'd spot some droplets right there!

Bro and i use a toilet which requires buckets to flush 😭😭😭
Earlier research showed that air passing under a closed lid is accelerated by a venturi effect that spreads the aerosol much further!
Lol what do you think happens when you flush that thing without a lid on?

THIS 100%. *Most* toilets at home don’t mix enough air and are not fast enough to make this sort of a mess.
Imagine when you turn on the ventilation fan, how far the yucky stuff would spread...
Spray desinfectan before flush.
Cat food near the toilet? You realize when you flush the toilet water particles and “other” particles spray everywhere?
But then even toilets at home, with the lid down, its still all over the seat 😢 i need seat covers at home now too
Theres so much water on his lid, thats just not realistic at all lol
Thats a powerful flush lol its like Niagara Falls lol 😆 did you see how wet the seat was 🤭 that was a CRAP test 💩

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?

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? ?
