Anyone try the baking soda test?

Amanda
So I am just curious if anyone else has tried the baking soda gender test... I just did it this morning and it had absolutely no reaction which means girl.. My sister and I also did the old wife's tale with the wedding band on the string which went in a circle.. Also meaning girl.. According to fhr (169 at 9w1d) its a girl.. The Mayan and Chinese gender charts day boy... I am really doing all these tests for fun... I truely don't care what this baby is as long as she/he is happy and healthy.. I am just curious what result everyone else got
