The baking soda test! Most of us have this lovely little powder somewhere in our kitchen, and because it's around $30 less than the Intelligender test, I can understand peeing on a little of it for shiits and giggles! Lol!
I guess you put 1-2 tsp in a jar/glass/pee cup and then add pee. If it fizzes and foams, it's a boy. If it does nothing at all, it's a girl. Make sure to run out and buy everything available for the gender it tells you!!!!
