Some actually claims it works. All you’ll need is some baking soda in a small container and another clean container to catch your urine.First morning urine is preferred with this test, since drinking water throughout the day is thought to dilute the urine and skew the results.Once you have these two crucial ingredients, slowly pour the urine into the baking soda and watch to see if it fizzes.If the urine fizzes or sizzles in the baking soda, you’re supposedly having a boy. If nothing happens and it stays flat, you’re supposedly having a girl but remember this is not 100% accurate
