Fun early gender reveals

Are there any fun or old wives tales to find out the gender of the baby in early pregnancy? (For fun)

For example, I heard the purple cabbage test, but not sure when you can take it. And the other one is the back of the hairline of you last child. If it ends as a tail, then a girl, if it is straight then a boy. I can't take intelligender yet.
