YouTuber Jen Cardinal posted this mind-boggling video today, writing: "at our 14 week ultrasound our baby was clapping, so I sang a song with our doctor, while my husband filmed."
BuzzFeed spoke to Dr. Jen Gunter, an OB-GYN, blogger, and author, to find out whether or not this was possible. According to Gunter, "A 14-week fetus isn't capable of purposeful gross motor movement," but that doesn't mean that it's fake.
"The hands hit each other, but it is not what we consider clapping," Jen continued. "What you see is just fetal movement, that with some very careful editing gives the appearance of a clap. It's the ultrasound version of a parlor trick."
So it's not necessarily fake, but it's not necessarily real either.
Cardinal has not yet responded to a request for comment from BuzzFeed.
