Ring Test

My fiancé and I just did the ring test for some fun. I tried it first and the ring went in a circular motion so my partner tried it too and it also went in a circular motion for him. Circular means girl! 
Has anyone else been trying out the old wives tales for fun? Has anyone's ever been right before? Or just plain wrong? 
P.s no nasty comments - whatever gender our baby is we'll love it regardless. We're just having fun.
