One teacher's simple (and disgusting) experiment drives home the importance of hand washing

One teacher's simple (and disgusting) experiment drives home the importance of hand washing

One of the most major breakthroughs in preventing the spread of illnesses and infections in hospitals was embarrassingly simple. Wash your hands. In 1846, Hungarian physician Ignaz Semmelweis discovered that hand washing played a vital role in the spread of germs, and the practice soon became mandatory in hospitals. The simple act of scrubbing hands with soap and water literally saved lives.

Getting a kid to wash their hands, however, can be an uphill battle. One teacher did a simple experiment to show her students just how important hand washing is.


"We did a science project in class this last month as flu season was starting," teacher Dayna Robertson wrote on Facebook. "We took fresh bread and touched it. We did one slice untouched. One with unwashed hands. One with hand sanitizer. One with washed hands with warm water and soap. Then we decided to rub a piece on all our classroom Chromebooks." Robertson later noted that they normally do make a point to sanitize the classroom Chromebooks, but didn't that day in the name of science.

RELATED: A 5th-grader made a discovery about stuffed animals and germs. It landed her in a medical journal.

The bread was put into plastic bags and the germs were left to fester. The bread that had been touched by unwashed hands and the bread that had touched the Chromebook had the most mold on it. The experiment proves that nothing beats soap and water. The bread that had been touched by hands washed with soap and water remained (relatively) good enough to eat.



This experiment has been done before, but Robertson expanded on it by testing the effectiveness of hand sanitizer. The bread that had been touched by hands cleaned with sanitizer also had a fair amount of mold on it, although not as much as the bread touched by unwashed hands.

"As somebody who is sick and tired of being sick and tired of being sick and tired," Robertson wrote. "Wash your hands! Remind your kids to wash their hands! And hand sanitizer is not an alternative to washing hands!! At all!" It's kind of making us retroactively gag over seeing port-a-potties with hand sanitizer set up in lieu of sinks.

The experiment was prompted by a different science lesson. "We had just finished a science lesson on how leaves break down during winter. The kids were kind of grossed out by the mold, so we decided to run our own version using germs and mold from our own environment," Robertson told Scary Mommy.

Weirdly, the classroom experiment received some criticism. "Lots of people actually DEFENDED not washing their hands!" Robertson told Scary Mommy. "That was shocking! It really was just a simple classroom experiment to teach about mold but we have all learned more about how easily we can spread the germs we can't see."

The moral of the story is, please, please remember to always wash your hands.

True

Women are breaking down barriers every day. They are transforming the world into a more equitable place with every scientific discovery, athletic feat, social justice reform, artistic endeavor, leadership role, and community outreach project.

And while these breakthroughs are happening all the time, International Women’s Day (Mar 8) is when we can all take time to acknowledge the collective progress, and celebrate how “She Leads the World.

This year, CARE, a leading global humanitarian organization dedicated to empowering women and girls, is celebrating International Women’s Day through the power of portraiture. CARE partnered with high-profile photographer Nigel Barker, best known for his work on “America’s Next Top Model,” to capture breathtaking images of seven remarkable women who have prevailed over countless obstacles to become leaders within their communities.

“Mabinty, Isatu, Adama, and Kadiatu represent so many women around the world overcoming incredible obstacles to lead their communities,” said Michelle Nunn, President and CEO of CARE USA.

Barker’s bold portraits, as part of CARE’s “She Leads The World” campaign, not only elevate each woman’s story, but also shine a spotlight on how CARE programs helped them get to where they are today.

About the women:

Mabinty

international womens day, care.org

Mabinty is a businesswoman and a member of a CARE savings circle along with a group of other women. She buys and sells groundnuts, rice, and fuel. She and her husband have created such a successful enterprise that Mabinty volunteers her time as a teacher in the local school. She was the first woman to teach there, prompting a second woman to do so. Her fellow teachers and students look up to Mabinty as the leader and educator she is.

Kadiatu

Kadiatu supports herself through a small business selling food. She also volunteers at a health clinic in the neighboring village where she is a nursing student. She tests for malaria, works with infants, and joins her fellow staff in dancing and singing with the women who visit the clinic. She aspires to become a full-time nurse so she can treat and cure people. Today, she leads by example and with ambition.

Isatu

When Isatu was three months pregnant, her husband left her, seeking his fortune in the gold mines. Now Isatu makes her own way, buying and selling food to support her four children. It is a struggle, but Isatu is determined to be a part of her community and a provider for her kids. A single mother of four is nothing if not a leader.

Zainab

international womens day, care.org

Zainab is the Nurse in Charge at the Maternal Child Health Outpost in her community. She is the only nurse in the surrounding area, and so she is responsible for the pre-natal health of the community’s mothers-to-be and for the safe delivery of their babies. In a country with one of the world’s worst maternal death rates, Zainab has not lost a single mother. The community rallies around Zainab and the work she does. She describes the women who visit the clinic as sisters. That feeling is clearly mutual.

Adama

international womens day, care.org

Adama is something few women are - a kehkeh driver. A kehkeh is a three-wheeled motorcycle taxi, known elsewhere as a tuktuk. Working in the Kissy neighborhood of Freetown, Adama is the primary breadwinner for her family, including her son. She keeps her riders safe in other ways, too, by selling condoms. With HIV threatening to increase its spread, this is a vital service to the community.

Ya Yaebo

international womens day, care.org

“Ya” is a term of respect for older, accomplished women. Ya Yaebo has earned that title as head of her local farmers group. But there is much more than that. She started as a Village Savings and Loan Association member and began putting money into her business. There is the groundnut farm, her team buys and sells rice, and own their own oil processing machine. They even supply seeds to the Ministry of Agriculture. She has used her success to the benefit of people in need in her community and is a vocal advocate for educating girls, not having gone beyond grade seven herself.

On Monday, March 4, CARE will host an exhibition of photography in New York City featuring these portraits, kicking off the multi-day “She Leads the World Campaign.

Over or under? Surprisingly, there actually is a 'correct' way to hang a toilet paper roll.

Let's settle this silly-but-surprisingly-heated debate once and for all.

Should you hang the toilet paper roll over or under?



Upworthy book

Humans have debated things large and small over the millennia, from the democracy to breastfeeding in public to how often people ought to wash their sheets.

But perhaps the most silly-yet-surprisingly-heated household debate is the one in which we argue over which way to hang the toilet paper roll.

The "over or under" question has plagued marriages and casual acquaintances alike for over 100 years, with both sides convinced they have the soundest reasoning for putting their toilet paper loose end out or loose end under. Some people feel so strongly about right vs. wrong TP hanging that they will even flip the roll over when they go to the bathroom in the homes of strangers.

Contrary to popular belief, it's not merely an inconsequential preference. There is actually a "correct" way to hang toilet paper, according to health experts as well as the man who invented the toilet paper roll in the first place.

Brielle Asero lost her job after 2 months.

TikTokker Brielle Asero, 21, a recent college graduate, went viral on TikTok in October for her emotional reaction to the first day at a 9-to-5 job. The video, which received 3.4 million views, captured the public’s attention because it was like a cultural Rorschach test.

Some who saw the video thought that Asero came off as entitled and exemplified the younger generation’s lack of work ethic. In contrast, others sympathized with the young woman who is just beginning to understand how hard it is to find work-life balance in modern-day America.

“I’m so upset,” she says in the video. "I get on the train at 7:30 a.m., and I don't get home until 6:15 p.m. [at the] earliest. I don't have time to do anything!" Asero said in a video.

If you just got married, chances are lots of people think they know what your life is like.

These people are totally well-meaning! And also, mostly wrong.

So let's get them out of the way in one fell swoop.

Here are the most common (but mistaken) assumptions strangers make when you're a newlywed couple, and what our lives are really like.

Around 1 a.m. on April 24, semi-truck drivers in the Oak Park area of Michigan received a distress call from area police: An unidentified man was standing on the edge of a local bridge, apparently ready to jump onto the freeway below.

Those drivers then did something amazing. They raced to the scene to help — and lined up their trucks under the bridge, providing a relatively safe landing space should the man jump.
