Take 1 tblspn baking soda
and put it into a clean, dry cup. Add urine to the baking soda, if it fizzles its mean its a boy and if it does nothing its supposed to mean your expecting a girl.
I dont know my babies gender yet, but I tried it and it says im having a girl. I will update after my gender scan.
Everyone try it, if you already know the gender it will help us see how accurate it is, and if you dont know the gender yet its fun to see how the results compare!
