Magic Pregnancy Test?

Recently I witnessed something very shocking. A friend held a gold chain and ring over someones hand and predicted what children they had. If the ring swung back and forth it would meen a boy and if it were to swing in a circle then it would be a girl. It even stoped all by itself between each child and then started again in a different motion. This elegedly also predicts what children you are going to have and in what order. Sounds stupid I know, but honestly I am not kidding you. Since then my wife has been trying this on everyone for the past few days and it doesn't fail, it is becoming more and more spooky. Now she is convinced that we are going to have boy,girl,boy in that order as our results are both the same every time.

The friend who showed us this said it is to do with the bodies electrical impulces.

Anyone else heard of this and can anyone begin to explain it?
