Gender tests

So there's this theory on the internet that if you're having a boy, the pH of your urine is more acidic than having a girl. You can test the pH of your urine with various household chemicals. I tried this tonight because I think it will make an interesting experiment to try several times over the course of a few days and see if the pH of my urine holds steady or if the results change.

First, we tested it using pH paper. The whole point of doing the other tests is that most households don't have pH paper laying around... but we're a scientific sort of a family. My urine is around pH 6.

When we added pee to baking soda, we saw only very limited fizzing (like just bubbles escaping from the baking soda because it's a dry powder). Supposedly, this means it's a girl.

An equal volume of pee added to bleach also produced only limited fizzing. Supposedly if it's a boy, it can even foam over the top of the container. My bleach + pee solution bubbled slightly, like soda. This test smelled bad and the internet warns that the gas produced from this reaction can be toxic (although other parts of the internet thought that was an overreaction). Since the same results were achieved via baking soda and bleach tests, I'm going to skip the bleach test from now on.

Alright, survey says it's a girl. That disagrees with the Intelligender test I took earlier on. I believe that test is also a pH-based test, which lends support to the idea that urine changes pH according to diet. I'll try again tomorrow and report back.
