Making these cute watermelon bath bombs was so much fun and I was really surprised that the process of making these embed bath bombs was so fast! I mean, sometimes, when you’re having fun, time just flies.
And, you’d think, with two colors, sprinkle embeds, and the painted-on seeds, that the process would take forever and drag–especially when you’re making a big batch. But really, it was such fun, I was done before I realized it.
Seriously, these took about 20 minutes of actual “work” and given that all that was split between two days, well, that was just a huge bonus that made it feel like no effort at all. Any craft project I can do in less than 20 minutes of effort is so awesome, I get jazzed and definitely have fun.
Plus, the couple of people I have in mind to give these watermelon bath bombs will also find out, these are a TON of fun. They’re super fizzy and smell wonderful–like watermelon candy.
Which is one of the best things about having bath bombs that smell like watermelon–because who wants real watermelon fragrance?! Nobody, that’s for sure. It’s nice, right, when you’re eating a big salty slab, but if you’re going to be honest with yourself, in the bath, the candy version of watermelon is a million times better.
So, the fact that these bath bombs are watermelon candy flavored is an amazing benefit that I feel needs to be explored. At length. In the bath.
Oh, you’re not ready for a bath quite yet? That’s ok! Just pin this to your favorite bath bomb board on Pinterest so you can find them again super quick when you’re ready to make a batch!

Supplies
- 1 cup baking soda
- 1/2 cup citric acid
- 1/2 cup cornstarch
- 1/4 cup epsom salts
- 2 tbsp melted coconut oil
- 1/2 tsp essential oil blend desired (or watermelon flavoring oil, since that’s what I wanted–this is what I used: https://www.amazon.com/LorAnn-Oils-Watermelon-1-dram/dp/B00016V2DC)
- 2 tsp rubbing alcohol
- 3/4 tsp arashiyama green mica powder (I used: https://www.amazon.com/Pigment-Arashiyama-Multipurpose-Additive-Woodworking/dp/B087YWSY4S/)
- 3/4 tsp pink mica powder (I used: https://www.amazon.com/Eye-Candy-Shibazakura-Multipurpose-Woodworking/dp/B087234PKC)
- 2-4 tablespoons watermelon sprinkles blend (I used: https://www.etsy.com/listing/600865068/pink-watermelon-sprinkle-mix)
- To make the black watermelon seeds
- ½ tsp black mica powder
- 2-3 drops alcohol
Tools
- 4-5 large bath bomb molds
Instructions
- Whisk together the baking soda, citric acid, cornstarch and epsom salts.
- In a second bowl, combine the melted coconut oil, essential oil blend and alcohol together, mixing well.
- Add liquid ingredients 1 tsp at a time to the dry ingredients, mixing it together slowly so as not to start the fizzy reaction.
- Separate about ⅓ of the bath bomb mixture into a second small bowl. To this smaller bowl of bath bomb mixture, add in the green mica powder and mix well. If you want more color, add some additional mica powder in 1 tsp increments.
- To the larger bowl of bath bomb mixture, add in the pink mica powder and mix well. If you want more color, add some additional mica powder in 1 tsp increments.
- Dust the bottom of one side of one of the bath bomb molds with cornstarch. The sprinkle side tends to come out on its own, so do not bother to dust that side with cornstarch.
- Place about 1 tsp of sprinkles in the non-dusted side of the bath bomb mold.
- Immediately pack the bath bomb mold with the sprinkles overly full of the pink mixture. You want there to be excess mixture to help bond the two sides of the mold together.
- To the cornstarch dusted half of the bath bomb mold, fill it about ½ full of green bath bomb mixture, then finish filling it with the pink mixture, overfilling as with the other half of the bath bomb.
- Press the two sides of the bath bomb mold together, grinding and pressing them to force the two together.
- Allow the bath bombs to rest in the mold for up to 24 hours before gently tapping the side of the mold to release the bombs.
- To make the watermelon seeds, combine the black mica powder and the alcohol and paint the seeds onto the bath bomb, as desired.
- Use your bath bombs immediately or store in an airtight container until you’re ready to use!
