Teacher uses a balloon and ping pong ball to explain childbirth in viral TikTok video

As someone who has given birth to three children and who was raised by a labor-and-delivery nurse, you'd think I'd have a good handle on the physical mechanics of childbirth. But despite knowing all the terminology and experiencing all the details first hand—uterine contractions, cervical dilation, etc.—I'm a visual person, and most of the birth process happens internally. Feeling it and being told what's happening isn't the same as being able to visualize what's actually happening.

Enter high school teacher Brooke Bernal, who teaches consumer sciences. She shared a video on TikTok demonstrating how she teaches her students about childbirth, which she says is her "all time favorite lesson," using a balloon and a ping-pong ball. It's a simple, but-oh-so-helpful demonstration that even helped me get a better grip on the miracle of childbirth. (Without the baby shooting across the room at the end, of course.)


Bernal explains that the big round part of the balloon is the uterus, the skinny tube part is the birth canal, and the opening is the cervix. Then she puts a ping-pong ball into the balloon and shows how the pressure of the contractions causes the ball baby to push on the cervix, causing it to thin out (efface) and open up (dilate).

There's one little hiccup with this demonstration, which is that the "birth canal" isn't actually above the cervix like shown in Bernal's video. The cervix is immediately outside of the uterus, and then the birth canal is the vagina below that. So in a real birth, what you see happening with the cervix would happen before the baby goes through the birth canal (and is, in fact, what allows the baby to do so).

A video that may have served as the inspiration for this one (Bernal told Buzzfeed that she had seen the idea shared in a teacher group on social media but wasn't sure where it came from) illustrates that a bit more clearly:

Aside from the birth canal bit, Bernal's video is great. The first awesome part is how she illustrates the difference between Braxton-Hicks contractions and real contractions. For those who haven't experienced the joy of thinking you were in labor half a dozen times before you actually were, Braxton-Hicks contractions are basically practice contractions. It's your uterus running drills. Some people have them for weeks before real labor starts, and they can be pretty uncomfortable..

Real contractions come from the top of the uterus and actually move the baby down into the birth canal. This part of the video makes that difference so clear.

The other part that I found helpful was the effacement and dilation illustrations. Not being able to see your own cervix, it's hard to imagine what a midwife or doctor means when they tell you you're "90% effaced" or "7 cm dilated." You can see it in drawn diagrams, but I don't find those nearly as helpful as watching that balloon opening get thinner and wider as the ball was being pushed down.

"Normally, this demonstration does not faze my students at all," Bernal told Buzzfeed. "They are really just surprised that a ping pong ball can fit into a balloon and that a balloon can stretch like it does without popping. It's just a good visual aid for them."

"And, yes, they know a baby will not actually yeet across the room!" she added. "I personally feel that they get more out of me showing it this way than they would watching birthing videos because it's something that is hands on and they can't just zone out."

I will say, though, that as illustrative as it was to see the mechanics of contractions, effacement, and dilation goes, it's definitely a limited demonstration. First of all, babies are nowhere near the size of a ping-pong ball, and that whole contraction > effacement > dilation > baby popping out process takes a heck of a lot longer and involves a crapton more work than that. It doesn't even touch on the reality of what our bodies go through and what it's really like to grow an entire human being and then push it out through an opening that does not look or feel nearly large enough to do so.

So yes, this demonstration (with the caveat about the birth canal) combined with some real-life footage would go a long way in helping people understand what's happening during childbirth.

Well done, Ms. Bernal.

When Grace Berbig was 7 years old, her mom was diagnosed with leukemia, a cancer of the body’s blood-forming tissues. Being so young, Grace didn’t know what cancer was or why her mother was suddenly living in the hospital. But she did know this: that while her mom was in the hospital, she would always be assured that her family was thinking of her, supporting her and loving her every step of her journey.

Nearly every day, Grace and her two younger sisters would hand-make cards and fill them with drawings and messages of love, which their mother would hang all over the walls of her hospital room. These cherished letters brought immeasurable peace and joy to their mom during her sickness. Sadly, when Grace was just 10 years old, her mother lost her battle with cancer.“

Losing my mom put the world in a completely different perspective for me,” Grace says. “I realized that you never know when someone could leave you, so you have to love the people you love with your whole heart, every day.”

Grace’s father was instrumental in helping in the healing process of his daughters. “I distinctly remember my dad constantly reminding my two little sisters, Bella and Sophie, and I that happiness is a choice, and it was now our job to turn this heartbreaking event in our life into something positive.”

When she got to high school, Grace became involved in the Leukemia & Lymphoma Society and a handful of other organizations. But she never felt like she was doing enough.

“I wanted to create an opportunity for people to help beyond donating money, and one that anyone could be a part of, no matter their financial status.”

In October 2018, Grace started Letters of Love, a club at her high school in Long Lake, Minnesota, to emotionally support children battling cancer and other serious illnesses through letter-writing and craft-making.

Much to her surprise, more than 100 students showed up for the first club meeting. From then on, Letters of Love grew so fast that during her senior year in high school, Grace had to start a GoFundMe to help cover the cost of card-making materials.

Speaking about her nonprofit today, Grace says, “I can’t find enough words to explain how blessed I feel to have this organization. Beyond the amount of kids and families we are able to support, it allows me to feel so much closer and more connected to my mom.”

Since its inception, Letters of Love has grown to more than 25 clubs with more than 1,000 members providing emotional support to more than 60,000 patients in children’s hospitals around the world. And in the process it has become a full-time job for Grace.

“I do everything from training volunteers and club ambassadors, paying bills, designing merchandise, preparing financial predictions and overviews, applying for grants, to going through each and every card ensuring they are appropriate to send out to hospitals.”

In addition to running Letters of Love, Grace and her small team must also contend with the emotions inherent in their line of work.

“There have been many, many tears cried,” she says. “Working to support children who are battling cancer and other serious and sometimes chronic illnesses can absolutely be extremely difficult mentally. I feel so blessed to be an organization that focuses solely on bringing joy to these children, though. We do everything we can to simply put a smile on their face, and ensure they know that they are so loved, so strong, and so supported by people all around the world.”

Letters of Love has been particularly instrumental in offering emotional support to children who have been unable to see friends and family due to COVID-19. A video campaign in the summer of 2021 even saw members of the NFL’s Minnesota Vikings and the NHL’s Minnesota Wild offer short videos of hope and encouragement to affected children.

Grace is currently taking a gap year before she starts college so she can focus on growing Letters of Love as well as to work on various related projects, including the publication of a children’s book.

“The goal of the book is to teach children the immense impact that small acts of kindness can have, how to treat their peers who may be diagnosed with disabilities or illness, and how they are never too young to change the world,” she says.

Since she was 10, Grace has kept memories of her mother close to her, as a source of love and inspiration in her life and in the work she does with Letters of Love.

“When I lost my mom, I felt like a section of my heart went with her, so ever since, I have been filling that piece with love and compassion towards others. Her smile and joy were infectious, and I try to mirror that in myself and touch people’s hearts as she did.”

Please donate to Grace’s GoFundMe and help Letters of Love to expand, publish a children’s book and continue to reach more children in hospitals around the world.

The day was scorching hot, but the weather wasn’t going to stop a Star Wars Stormtrooper from handing out school supplies to a long line of eager children. “You guys don’t have anything illegal back there - any droids or anything?” the Stormtrooper asks, making sure he was safe from enemies before handing over a colorful backpack to a smiling boy.

The man inside the costume is Yuri Williams, founder of AFutureSuperhero And Friends, a Los Angeles nonprofit that uplifts and inspires marginalized people with small acts of kindness.

Yuri’s organization is one of four inaugural grant winners from the Upworthy Kindness Fund, a joint initiative between Upworthy and GoFundMe that celebrates kindness and everyday actions inspired by the best of humanity. This year, the Upworthy Kindness Fund is giving $100,000 to grassroots changemakers across the world.

To apply, campaign organizers simply tell Upworthy how their kindness project is making a difference. Between now and the end of 2021, each accepted individual or organization will receive $500 towards an existing GoFundMe and a shout-out on Upworthy.

Meet the first four winners:

1: Balance Dance Project: This studio aims to bring accessible dance to all in the Sacramento, CA area. Lead fundraiser Miranda Macias says many dancers spend hours a day at Balance practicing contemporary, lyrical, hip-hop, and ballet. Balance started a GoFundMe to raise money to cover tuition for dancers from low-income communities, buy dance team uniforms, and update its facility. The $500 contribution from the Kindness Fund nudged Balance closer to its $5,000 goal.

2: Citizens of the World Mar Vista Robotics Team: In Los Angeles, middle school teacher James Pike is introducing his students to the field of robotics via a Lego-building team dedicated to solving real-world problems.

James started a GoFundMe to crowdfund supplies for his students’ team ahead of the First Lego League, a school-against-school matchup that includes robotics competitions. The team, James explained, needed help to cover half the cost of the pricey $4,000 robotics kit. Thanks to help from the Upworthy Kindness Fund and the generosity of the Citizens of the World Middle School community, the team exceeded its initial fundraising goal.

3: Black Fluidity Tattoo Club: Kiara Mills and Tann Parker want to fix a big problem in the tattoo industry: there are too few Black tattoo artists. To tackle the issue, the duo founded the Black Fluidity Tattoo Club to inspire and support Black tattooers. While the Brooklyn organization is open to any Black person, Kiara and Tann specifically want to encourage dark-skinned artists to train in an affirming space among people with similar identities.

To make room for newcomers, the club recently moved into a larger studio with a third station for apprentices or guest artists. Unlike a traditional fundraiser that supports the organization exclusively, Black Fluidity Tattoo Club will distribute proceeds from GoFundMe directly to emerging Black tattoo artists who are starting their own businesses. The small grants, supported in part with a $500 contribution from the Upworthy Kindness Fund, will go towards artists’ equipment, supplies, furnishings, and other start-up costs.

4: AFutureSuperhero And Friends’ “Hope For The Holidays”: Founder Yuri Williams is fundraising for a holiday trip to spread cheer to people in need across all fifty states.

Along with collaborator Rodney Smith Jr., Yuri will be handing out gifts to children, adults, and animals dressed as a Star Wars’ Stormtrooper, Spiderman, Deadpool, and other movie or comic book characters. Starting this month, the crew will be visiting children with disabilities or serious illnesses, bringing leashes and toys to animal shelters for people taking home a new pet, and spreading blessings to unhoused people—all while in superhero costume. This will be the third time Yuri and his nonprofit have taken this journey.

AFutureSuperhero started a GoFundMe in July to cover the cost of gifts as well as travel expenses like hotels and rental cars. To help the nonprofit reach its $15,000 goal, the Upworthy Kindness Fund contributed $500 towards this good cause.

Cellist Cremaine Booker's performance of Faure's "Pavane" is as impressive as it is beautiful.

Music might be the closest thing the world has to real magic. Music has the ability to transform any atmosphere in seconds, simply with the sounds of a few notes. It can be simple—one instrument playing single notes like raindrops—or a complex symphony of melodies and harmonies, swirling and crashing like waves from dozens of instruments. Certain rhythms can make us spontaneously dance and certain chord progressions can make us cry.

Music is an art, a science, a language and a decidedly human endeavor. People have made music throughout history, in every culture on every continent. Over time, people have perfected the crafting of instruments and passed along the knowledge of how to play them, so every time we see someone playing music, we're seeing the history of humanity culminated in their craft. It's truly an amazing thing.

The pandemic threw a wrench into seeing live musicians for a good chunk of time, and even now, live performances are limited. Thankfully, we have technology that makes it easier for musicians to collaborate and perform with one another virtually—and also makes it easier for people to create "group" performances all by themselves.

A round-up of delights from around the internet this week.

Hey all!

Welcome to Upworthy's weekly roundup of delights from around the internet. This week's list features a little of everything—gorgeous music, cute kids, adorable animals, hope for the planet and a brand new video message from the late and great Betty White.

That's right, Betty White left us a message of gratitude shortly before her passing. It's brief, but how lovely to see and hear her speak to her millions of fans one last time. Few celebrities are as universally beloved as Betty White was, and though we knew she couldn't live forever, it would have been fun to see her celebrate her 100th birthday. Now, at least, we get to experience her joy and warmth with a few last words.
