This Brilliant Video Explains Childbirth Using Just A Balloon And A Ping Pong Ball

Mystified by the process behind giving birth? Liz Chalmers, owner of the Puget Sound Birth Center in the Seattle area, has used just a balloon and a ping pong ball to demonstrate the process of cervical dilation—and her video has gone viral, with over 24,000 shares so far on Facebook.

In the video, the ping pong ball represents a baby, the balloon acts as a uterus and the neck of the balloon acts as the cervix, the portion of the uterus that opens to allow the baby to pass through the vagina. During labor, a cervix must open to 10 cm (full dilation) before birth can occur.

Chalmers made this video for her niece, who is becoming a childbirth educator in New Zealand. She says she learned the idea from a course called “Stomp Out Boring Childbirth Classes.”
