Do you love taking a long, relaxing bath at the end of a hard day? Then why not take your luxurious soak to the next level with some homemade watermelon bath bombs! Not only will these fragrant and fizzy treats make your tub time even more relaxing, but they’re also fun and easy to make. Read on for our step-by-step guide on how to create these colorful and refreshing DIY watermelon bath bombs.
Supplies Needed To Make the DIY Watermelon Bath Bomb Recipe
- *2 cups baking soda (I get the 4-pound bag at Walmart)
- 1 cup citric acid
- 1/4 cup cream of tartar
- 1/4 cup Epsom salts
- ¼ cup powdered goat milk
- 1/3 cup coconut oil
- 1 teaspoon polysorbate 80
- Red mica colorant
- Green mica colorant
- **Watermelon Scented oil
- ½ teaspoon black cosmetic (skin safe) glitter
- 1-2 tablespoons poppy seeds (depending on how many “seeds” you’d like)
Watermelon Scented Bath Bombs Tutorial
Melt any coconut oil in a microwave safe container in 30 second bursts. Stir in between each. Continue until completely melted.
Step 1: In a large mixing bowl, add the baking soda, citric acid, cream of tartar and goat milk. Whisk dry ingredients together. (If desired, sift dry ingredients to rid the mixture of any clumps or hard pieces)
Step 2: Add the coconut oil and scented oil. The coconut oil binds all the ingredients together, so your bath bombs don’t crumble when you touch them. Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly, and prevents the mica from sticking to the side of the tub.
Step 3: Mix wet ingredients in well. You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand.
Steps 4-5: Divide the mixture into 2 bowls. Add 1-2 teaspoons of the green mica to one bowl and the same amount of the red to the other bowl. Continue to add a bit of mica until you achieve the color you desire.
Steps 6-7: Mix the glitter and poppy seeds together. Add to the bowl with the red bath bomb mixture and mix well.
Directions for Molding the Bath Bombs:
Step 8: Add the green mixture to one of the bath bomb molds, filling it about 1/2-2/3 full. Add the red bath bomb mixture until the mold is slightly overflowing. Add the red to the other bath bomb mold until it too is slightly overflowing.
Step 9: Over the smaller, empty bowl, press molds together and gently but firmly grind to remove any excess mixture. Gently tap mold to release the bombs. Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container for up to 6 months until ready for use.
*Some links may show a larger bag. This is done because the price per bag is higher but the cost per ounce is lower. Of course, there are others in a smaller amount at a lower cost per bag
**If using on children, please check a trusted source for the safe amount to use.
Recipe notes and tips:
While the recipe is straightforward, it is always nice to have a few different tips and suggestions to make things easier. So here are some of the recipe notes and tips to help you out:
- Be sure to spray the molds with rubbing alcohol before filling them. This will ensure that they don’t stick together when you are pushing them out of the mold.
- If you want a smoother bath bomb, sift your dry ingredients before adding them to the wet mixture.
- For a more uniform bath bomb, try to use the same sized scoop when adding your wet and dry ingredients.
- If you are having trouble shaping your bombs, wet your hands before handling the mixture. This will help keep it from sticking to your hands.
- Adding some essential oils can give your bombs a nice scent. Lavender, lemon, and eucalyptus are all great options!
- For a more moisturizing bath bomb, try adding some shea butter or cocoa butter to your mixture.
- If you don’t have the time or energy to make your own watermelon bath bombs, you can find them pre-made at many stores and online retailers.
