What Makes Bath Bombs Fizz?

Bath bombs have changed bathing from a boring chore to a fancy and fun experience. People often wonder about the science that makes these little balls fizz and add magic to a regular bath. What causes these small spheres to break down so when they touch water? We'll look at the chemistry of bath bombs, what they do for you, and how to pick the right one for your next special bath.

Why Bath Bombs Fizz

The fizzing of bath bombs happens because of a basic chemical reaction. When you put a bath bomb in your tub, it starts a reaction that lets out carbon dioxide gas. Let's take a closer look at this bubbly process.

Bath bombs contain two acidic parts: baking soda and citric acid. These stay inactive when dry but start a chemical reaction in water.

When sodium bicarbonate and citric acid mix with water, they create sodium citrate, water, and carbon dioxide gas. The carbon dioxide release causes the bubbling and fizzing that bath bombs are known for.

Water plays a crucial role

Water starts the fizzing process. As soon as a bath bomb touches water, it breaks down the sodium bicarbonate and citric acid. This lets them mix and react. The reaction turns your bath into a bubbly spa-like treat.

How Colors and Glitters Work

Ever thought about what makes bath bombs so colorful and sparkly? Adding dyes and glitter to bath bombs makes them look better and feel more fun. Dyes can come from nature or be made in labs. More and more people who care about the planet are using glitters that break down in nature.

What's Good About Bath Bombs

Bath bombs do more than just create fun fizz. They offer lots of perks for your skin and senses.

Skin Hydration and Smoothing

Bath bombs are a great option for those with sensitive skin. They typically include oils and moisturizers that nourish your skin. Stuff like coconut oil, shea butter, and almond oil make your skin feel super soft after a soak.

Scent Therapy

The oils in bath bombs also have an impact on your mood through smell. Lavender chills you out, eucalyptus helps you breathe easier, and rose lifts your spirits. These are just a few ways bath bombs can boost your well-being with scent.


Bath bombs sometimes contain stuff like Epsom salt. This salt helps clean your body by pulling out dirt from your skin. It can make your skin healthier and help you relax more.

Scrubbing and New Skin
