So I saw a video online tonight about putting your ring on a strand of your hair, then outlining your hand and bringing it to the center and see how it swings. Apparently it's supposed to tell you gender and how many kids you'll have. Well it says I'll have 9 and I'm wondering if anyone's tried this and it worked lol.
