Learn how to make bath bombs with this easy homemade bath bomb recipe! Yummy scented watermelon DIY bath bombs make a great gift idea!
1 cupBaking Soda
1/2 cupEpsom Salt
3tbsp.Coconut Oil,melted (can also use fractionated coconut oil)
10-20dropsWatermelon Fragrance Oil
2 tbsp.Water or Witch Hazel,in spray bottle
1/2 tsp. Activated Charcoal Powder
1/4 tsp. Rubbing Alcohol(per powder colorant)
In a large bowl, mix together the baking soda, salt, citric acid, and cornstarch and stir until thoroughly combined. Divide the mixture into two bowls – about 1/3 of the mixture into one bowl and the remaining 2/3 in the other. Add a small amount of pink cosmetic coloring into the larger bowl and green to the smaller bowl, stirring gently until the color is thoroughly mixed in.
Melt the coconut oil if necessary and stir in the watermelon fragrance oil.
While constantly stirring, combine the wet and dry ingredients, SLOWLY dividing the liquid among the two bowls. Be careful not to pour too much liquid in all at once or the mixture will activate and start to fizz! Slowly and carefully stir the mixture until everything is thoroughly combined.
Squeeze the bath bomb mixture in your hand to test if it will stick together. If not, spray the mixture with 1-2 spritzes of water or witch hazel, mix well, and test again. Repeat until you reach the desired consistency. You want the mixture to hold together when compressed and compacted, but DO NOT GET THE MIXTURE TOO WET!
Fill the bottom portion of the mold with the green bath bomb mixture, pressing down to ensure that it is completely filled. Fill the remaining portion and the other half of the mold with pink mixture, and press both filled halves tightly together.
Allow to dry for at least 24 hours before unmolding. I recommend drying for an additional 24 hours after unmolding before handling, decorating, and gift packaging.
To make the black "seeds," mix a small amount of charcoal powder with rubbing alcohol at a 2:1 ratio. Use a paintbrush to carefully add black dots to the bath bomb.
