Baking soda sex prediction test

Hey ladies

So I don't know if anyone else has heard of it but I seen a new sex prediction test where you pour your pee over baking soda and if it foams like soda or beer it's a Boy and if it does nothing it's a girl. I watched a few videos on YouTube in regards to it bit both foamed so I thought it was probably fake. Anyway I did it myself. Put baking soda in a cup and peed on it. It foamed. .. quite a bit so I was like alright possible boy. I told my husband about it and he said okay... then he went and put baking soda in a cup and pissed in it. .. no foam! Just thought that was neat.

Anyway! What sex predictor tests has anyone tried, if any... so far I've done this and then I looked up through the Chinese lunar age sex prediction calendar. And my husband and a friend both did tarot reads... so far we are 2:2.
