Red cabbage gender test

I did this for fun today- i am DYING to know the sex of the baby-- it turned purple for me which means girl, i hope it's correct :)

1) Go to the store and buy a red cabbage

2) after you get home, cut up the red cabbage

3) add boiling water to the cabbage and let sit for 10 mins (or more)

4) remove cabbage from water SAVE THE WATER

5) add urine to the cabbage water

6) if it goes a red or pink color you are having a boy, if it goes a purple color you are having a girl
