Okay I have seen this in action when it comes to determining the sex of a bird. A breeder had shown me how it works a very long time ago. She was right about the birds I had purchased. I just forget which swing means what.
Please humor me.
I have tried the Chinese predictor. With 3 of my children two were right and one was wrong. I know that no one can tell me. Just curious to know what swing means what. Curosity has the best of me again. Wanting to see if it works, compare with future ultrasound, etc. Thanks in advance.
Safe Journey
