My sister has never been wrong... yet!!!

She does one either over the marital bed, or your tummy while pg. She needs the wedding ring, and cotton (for some reason it only works with cotton).

She'll ask if there is good spirits in the room, and the ring moves a certain way, if it doesn't move she can't do it... then asks which is yes and no then asks about the baby.,...

She got DD right, and said this was a girl before US said she was right!

Weird, but so far she hasn't been wrong with anyone!
