ring test to know marriage age and kids?

Anyone tried? For marriage, put a strand of your hair through your ring and then hold it in the middle of a glass bowl/cup and let it swing after dipping it 7 times (hit the bottom with the ring 7 times then let it hang in the middle of the bowl). Every time it hits the corner of the bowl and have a "ding" sound, you count 1. Keep counting till it stops swinging and that will be your age that you get married. Try it and let me know if it's true!
