Old wives tales/at home gender tests

Sheena

Hey guys! My hubby and I are having a gender reveal party July 6thh.

I thought it would he fun to have a board up with old wives tales/at home tests and the results of it

At home test:

I know of the Chinease Calander

Baking soda test

The ring or needle on a string

And the Mayan calendar

Old wives tales:

The side u sleep on

Skin (breaking out or not)

Craving sweet vs salty

And the heart rate

Any I'm missing?
