BuzzFeed spoke to Brooke, who said she got the idea from a Facebook page for family consumer science teachers. "A teacher posted a video of her doing it with her class and I loved it. I have no idea who the original creator is, but shoutout to them for being so creative," she said.
After Brooke posted the video to her TikTok, it went viral with nearly 5 million views. In the video, the ping pong ball symbolizes the baby and the balloon acts as the uterus, birth canal, and cervix.
After you put the ping pong ball (aka the baby) inside the balloon (aka all of the female anatomy parts listed above), you blow up the balloon and move the "baby" into the "birth canal." During contractions, we see the "baby" move toward the "cervix."
The "cervix" then dilates enough for the "baby" to come out! (Or, as some commenters said, the baby YEETS out.)
"Normally, this demonstration does not faze my students at all. 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! 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," explained Brooke.
Brooke, who is currently pregnant with her third child, said childbirth is important for all of her students to learn because it's a natural part of life. "My husband had no idea how a baby was born when I was pregnant with my first child. He did not believe me when I told him what all goes into having a baby, even though he took a child development class in high school. So, if I can provide basic knowledge to my students now, I am providing them with the tools and knowledge to feel comfortable and confident if they do get pregnant one day. I am also teaching them to be great support systems for someone who is having a baby," she added.
