The Baking Soda Gender Test: A Step-by-Step Guide

A fun, fizzy DIY experiment to guess your baby's sex at home!

If you’re stuck in the "waiting period" between your first positive test and your 20-week anatomy scan, you’ve likely looked for every possible way to find a clue. One of the most famous DIY experiments is the Baking Soda Gender Test.

It’s simple, cheap, and you probably already have everything you need in your kitchen. While it’s definitely not a replacement for medical science, it’s a staple in the world of guess baby gender folklore. Let's look at how to do it and what the results might mean!

How the Baking Soda Test Works

The theory behind this test is that your pregnancy hormones and your baby’s gender change the acidity (pH level) of your urine. When urine reacts with baking soda—a base—it will either fizz or stay still.

The Step-by-Step Instructions

  1. Gather Your Supplies: You’ll need a clean cup and about two tablespoons of fresh baking soda.
  2. The Timing: Use your first morning urine. This is when your urine is most concentrated and likely to give a "clear" reaction.
  3. The Process: Put the baking soda into a dry cup. Slowly pour an equal amount of your urine over the baking soda.
  4. Watch for the Reaction: This is the moment of truth!

The "Fizzy" Results

If it Fizzes (Like Soda):

According to the myth, if the mixture bubbles and fizzes like a freshly opened soft drink, you are likely carrying a boy.

If Nothing Happens (Flat):

If the baking soda just sits at the bottom of the cup and stays "flat" without any reaction, the old wives' tale says you are carrying a girl.

Is There Any Science to It?

In reality, the pH of your urine is affected by many things—what you ate for dinner, how much water you drank, and even your stress levels. There is no scientific evidence that the baby’s gender has a direct impact on the fizzing of baking soda. However, as far as "Old Wives' Tales" go, this is one of the most entertaining ones to try!
