Fun- baking soda gender test

Has anyone tried the baking soda gender test? If so how accurate were your results? I did it said boy.. I'll find out what I'm in about 5 weeks.... For you mommy's who don't know what it is, you put a table spoon of baking soda in a cup and add urine. If it fizzes and bubbles it's a boy if it died nothing it's a girl
