How to Make Fizzy Bath Bombs at Home

How to Make Fizzy Bath Bombs at Home 2

Of all the simple pleasures of life, sinking into a warm, fizzy water bath after an exhausting day is at the top of the list. The heavenly feeling of the hot bath is enhanced multi folds when you have made the fizzy bath bombs yourself. 

Although a good book, a soothing glass of wine, and mellow music are capable of making your experience nothing less than sheer delight, DIY bath bombs are the addition you need to amplify the beauty of your self-care time with fizzy goodness. 

The fizziness is caused by a fizzy reaction between baking soda and citric acid. The acidic nature of citric acid creates a reaction when combined with baking soda, a base. 

Would you like to know how to make bath fizzy with yummy smelling-scented homemade bath bombs? Here is a quick recipe for you to have the time of your life. 


What You Will Need

  • A small bowl and a large bowl for mixing
  • Spoons with measurements
  • Mixing spoon
  • A two-sided mold

Key Ingredients

  • Baking soda – 1 cup
  • Citric acid – 1/2 cup
  • Epsom Salt or Sea Salt 
  • Corn starch – 1/2 cup
  • A few drops of any essential oil of your preference
  • Food coloring (Optional)
  • Water 
  • Base Oil ( Almond oil, olive oil, Jojoba oil, or coconut oil)

Bath Bomb Instructions

Step 1 – Mix Ingredients (Baking Soda and Citric Acid) 

Measure and mix baking soda with corn starch in a large bowl. Break clumps if found any with the help of a spoon. Now add citric acid and Epsom salt (or sea salt). 

You can also use food coloring to add coloring essence to your bath bombs. 

Step 2 – Add Wet Ingredients Like Essential Oil 

Once the dry ingredients are mixed well, add wet ingredients like base oil, water, and essential oil. But first, whisk them in a small bowl and blend them. Different essential oils have varying benefits.

For example, lavender oil helps relieve stress, orange oil boosts energy levels and Chamomile oil assists in inducing sleep. 

A few CBD oil drops can also be added along with other oil as it has numerous health benefits. It is known for improving mood, reducing muscle soreness, and improving sleep quality. 


Here are a few essential oil combinations you can try as their scent is mesmerizing when combined:

  • Rosemary and Lavender
  • Myrrh and Frankincense 
  • Orange and Bergamot
  • Geranium and Rose
  • Orange and Patchouli
  • Tea tree and Geranium
  • Orange and Lemon
  • Rose and Lavender
  • Orange, clove, and sage
  • Jasmine and Patchouli 

Step 3 – Mixing the Wet Mixture with the Dry Mixture

This step of making a bath bomb requires extreme delicacy as the end product should not be a wet mixture, rather a dry, sandy one. Slowly pour the wet ingredients into the dry ones and continuously stir them until combined into a dry mixture. 

Use a large bowl as it will be easier for fast whisking and prevent any of the ingredients from falling out. You can test how well the mixture has been blended by smooshing the combined mixture together. If it sticks and does not fall apart, then you have done an excellent job. 

Step 4 – Molding

The mixture is well blended and ready to be molded into a fizzy bomb. Fill the two sides of the bath bomb mold with the mixture. Pack it and slightly overfill it. Press the sides of the mold with pressure and let it sit for a minute. 

Now, gently open a side of the mold and slowly flip the ball onto your hand and pull off the other side of the mold. Use a spoon to smoothen the seam of the ball. Handle gently as the bath bomb will still be damp and fragile. 

Step 5 – Drying the Bath Bomb 

It would be best if you dried the fizzy bath bombs before putting them in bathwater. Let them dry overnight at room temperature. Keeping the balls in an airtight container can help them dry faster. 

Tips and Tricks

Now you don’t have to take a trip to the grocery store before jumping into the tub. The more you make bath fizzies, the better you’ll become at creating them. However, we have shared a few tips and tricks from our experiences to assist you in making the best bath bombs below. 

Ingredients to Avoid

Certain substances attract too much moisture causing the bath bombs to become soft and less fizzy. Avoid putting honey, glycerin, sugar, and milk powders in your bath bombs mixture, as these ingredients actively absorb moisture. 

Storing Bath Bombs

Bath bombs tend to lose their fizzy quality if not stored properly. You should prevent exposing them to direct sunlight, high temperature, and humidity. An airtight container in a cool, dry place away from sunlight is the most suitable place to store bath bombs. 

Expiry of Bath Bombs

Although these fizzy balls do not have an expiry date, they tend to lose their effectiveness with time. They can be used months after their creation, but they are the freshest and most effective in the first three weeks. 

Therefore, storage condition is an essential determinant of the life span of bath bombs. 

Cornstarch can be Substituted

Cornstarch facilitates the hardening of the bath bombs. Therefore, if you would like to leave out cornstarch from your recipe, you need to substitute it with a substance that serves its purpose. Some alternatives you can use are Kaolin clay or Tapioca starch.

Maximum Fizziness

When bath bombs are used in hot water, the fizzy reaction is the maximum. This is because the heat of the water amplifies the chemical reactions of the substance that creates the fizz.

Final Word

Very easy to make, these fizz balls offer too many benefits for you not to involve them in your bathing time. They relieve stress, improve sleep, moisturize your skin, uplift your mood, detox your skin, reduce muscle pain, and best of all, make you smell amazing! 

Try making some for yourself, and you will truly enjoy the bathing experience!
