Make your own Holiday Bath Bomb! Instructions included in description.

This is the time of year to treat yourself and how can you do that better than with your own homemade bath bomb. Be sure to come on in and grab the supplies and then follow along with the instructions below. 

What You'll Need

Equipment / Tools

  • Mixing bowl
  • Measuring spoons
  • Spoon for stirring
  • Bath bomb molds


  • 1 cup Baking soda
  • 1/2 cup Citric acid
  • 1/2 cup Cornstarch
  • Food coloring
  • Essential oil of your choice
  • Water


1. Mix the Baking Soda and Constarch

Mix the baking soda and cornstarch in a large mixing bowl. For now, keep the citric acid set aside and do not mix it in. Use a mixing

spoon to break up any clumps.

Add Essential Oil

Add the essential oil a few drops at a time into the mixture and mix until fully incorporated. You may find that it's easier to use your hands to incorporate the oil, rather than a spoon. If desired, you can wear gloves to keep your hands clean.

Add the Coloring

Mix the color a few drops at a time into the dry mixture using your hands. The more drops you use, the deeper and more saturated the color will become.


If you're planning on making multiple colors of bath bombs from this single batch, separate the dry ingredients into equal parts in different bowls (you'll need to separate the citric acid as well).

Add the Water

Add water half a teaspoon at a time, stirring the mixture in after each addition. Keep adding water until the mixture becomes the texture of damp sand and will hold in a tight clump. You only need 1 and 1/2 tsp. of water to achieve this. If you add to much water when you add the citric acid the bath bomb will activate and you will have a large gooey mess. 

Add the Citric Acid

Add the citric acid and thoroughly combine until well-mixed.

Mold the Ball

Pack the two sides of your bath bomb mold full of the mixture. Pack it tightly and slightly overfill. Press the two sides of the mold together as tightly as you can. Leave for a minimum of 10 minuets to have them set before removing mold. Gently pull off one side of the mold, flip the ball over into your hand, and pull off the other side of the mold.


Handle the bath bomb very gently, as the mixture is still slightly damp and not yet hardened.

Smooth the Sides

Use the back of the spoon to smooth the seam of the ball where the molds met.

Let the Balls Dry

The bath bombs need to harden before they can be used. Leave them to dry overnight at room temperature. Do not over handle them or they will crumble and fall apart.
