Baking soda and gender theory

Deedee

Has anyone tried to do this before? You pee in a cup about half way and then add baking soda, if it fizzle like a soda it's a boy, if it doesn't and just sinks to the bottom it's a girl. I tried it for my first and I did end up having a girl, I just tried it this morning and I got that I was going to have another girl. I won't find out the gender for at least another month. Have any of you tried it before? And was it right or wrong?
