These bath bombs are perfect and just in time for spring and Easter! Use one by adding it to your bath and watch as the fragrance fills your room. Simple and easy to make, these bath bombs are the perfect gift, favor, or spa day kit for yourself. Let's Begin!

Step 1: Gather Materials

Picture of Gather Materials

This project is made with many materials that may already be available to you such as baking soda and cornstarch. The "ingredients" that you will need are:

  • 2 cups of Cornstarch
  • 1 3/4 cups of Baking Soda
  • 1 cup of Citric Acid
  • 1 tsp of your Essential Oil of choice (we used Orange Citrus because it is a light fragrance for any season)
  • A few drops of food coloring
  • Water (for food coloring)

The other materials that you will need are:

  • 20-25 Plastic Easter Eggs
  • 1 Egg Carton (for packaging)
  • Sifter (useful but not necessary)
  • 3 Medium/large bowls
  • 1-5 Spray-Bottles (Depending on how many colors you want to use)

Once all of these materials are gathered, we can get started!

Step 2: Preparing the Colors

Start by filling your spray bottle up with water. Then, using a food coloring color of your choice, add a couple of drops to your bottle. The shade you use will be lighter than the color of your bottle, so add more drops of color for a darker shade. You can use as many colors as you like, but we use three as our magic number because it is simple, though still keeping a nice variety. Typically, the colors will come out light and pastel.

Step 3: Mixing the Main Ingredients

Mix your cornstarch, baking soda, and citric acid by putting them through a sifter to make sure there are no clumps or chunks. A sifter in not necessary, but it does help to eliminate lumps. After that, mix the ingredients together so they are even throughout the mixture.

Step 4: Coloring the Mixture

Start by separating your mixture into bowl of however many colors you will use (3 colors, 3 bowls). Spray a few sprays of your color into the mixture, stirring after each spray. Be careful not to spray too much or your powder will fizz in a reaction with the water. Continue to spray until the powder had become your desired color and the mixture is the texture of wet, packable sand.

Step 5: Adding the Fragrance

When your powder is at the correct color and texture, get your fragrance. By either pouring very carefully or using a pipette (we used the squirter that comes with liquid medicine), add 2-3 drops of fragrance to each color. Then, mix to make sure the scent gets to all of the mixture.

Step 6: Forming the Eggs!

Start by adding a little bit of one color to the plastic egg. After packing it down, add another color. This will create an adorable striped pattern. When both sides of the egg are filled, close the shell.

Step 7: Let the Eggs Rest

Put your eggs aside and leave them to harden for 2 hours.

Step 8: "Cracking" the Eggs

After two hours have passed, you may begin to open your eggs. Be careful and take one side off at a time. If the egg does not come out easily, just wiggle it open with a butter knife.

Step 9: Broken Eggs?

If your egg breaks in the cracking process, the yolks on you! Just kidding… these eggs can be fixed by spraying enough water on each side and "gluing" them together to harden for 20 minutes.

Step 10: Packaging

For these eggstra special bombs, we packaged them by cutting up an egg carton. Then, we wrapped them in plastic and tied some curling ribbon on top. Easter basket grass also makes a great accent.

Step 11: Thanks!

This looks so fun! I may need to try to make them for my girlfriend sometime soon.

HunterMarie (author)2016-03-15

I made these but I noticed as I was packing them into the eggs they would fizz out and burst the egg open. Any tips with what I may be doing wrong? I made sure the mixture wasn't too wet.

is there a substatue for the citric acid

ashleyjlong (author)2015-03-30

Great gift idea! Using the plastic eggs as the mold is smart. What is the role of the citric acid in the bath bomb? I did an Instructable where the recipe involved cream of tar tar and baking soda with essential oils. They hold together fine, but were less fizzy in the tub than I hoped.

ghollister (author)ashleyjlong2015-03-31

The citric acid, when aded to water, reacts to the baking soda to cause fizzing (much like a baking soda and vinegar reaction). Cream of tartar would definitely work, but is a carboxylic acid and does not cause as big of a fizz. Thanks for asking!

Do we need citric acid??

ghollister (author)alexa1012015-03-30

Unfortunately, yes. It is one of the necessary ingredients because it (in combination with the baking soda), causes the fizzy reaction when put in a bath. Thank you for asking!
