Let’s talk about the science:
You may have taken a bubble bath using a bath fizzle, but do you know how and why it works? Bath fizzles do exactly what they sound like: they fizzle on contact with water due to a chemical reaction taking place between different ingredients.Â
The key ingredients in a bath fizzle are baking soda and citric acid. When baking soda and citric acid are mixed and then put in water, they undergo a chemical reaction which produces carbon dioxide, which makes bubbles in the water.
Another main ingredient in a bath fizzle is cornstarch. Changing the amount of cornstarch can affect how fizzy the bath fizzles turn out.
Using the correct terminology: This is an acid-base reaction, where baking soda is a weak base and citric acid is a weak acid. The cornstarch acts as a filler to control the reaction between the baking soda and citric acid.
