Old Wives Tales: How to Tell If Your Having a Boy or a Girl With a Penny & a String

By Lucia Mata ; Updated April 18, 2017
The penny-and-string gender test is a fun game for pregnant women.

One of the biggest questions expectant mothers have is whether their baby is a boy or a girl. While the only accurate way to know is by having an ultrasound done in the second trimester or waiting until the birth, many people swear by gender tests like the penny and string. This test is only a old wives’ tale, but it can be a fun game to enjoy before finding out the gender accurately.

Cut a piece of string to measure about 10 inches.

Tie the string around the penny a few times, making sure the penny is secure.

Lay down on your back. Hold the string with your hand over your stomach, with the penny pointing toward your body.

Analyze the way the penny is moving over your belly. If the penny moves up and down, your baby is a girl. If the penny moves in a circle, your baby is a boy.
