Seashell Bath Bombs Party Favours

| | |

Homemade bath bombs are not only a super easy DIY, they also make great gifts! If you have a friend with a summertime birthday coming up, these Seashell Bath Bombs would make the perfect mason jar gift! These would make a brilliant Mermaid Themed Party Favour gift idea (lots more great DIY Mermaid Ideas here!). They would also make a great birthday gift or end of school year gift for either teachers or teens needing some much deserved relaxation time.

Unlike those pretty seashell soaps people always keep in their guest bathroom, these seashell bath bombs are meant to be used!

Transform your tub into an oceanside retreat, we made these bath bombs in a variety of scents and colors – depending on your mood. Pop a couple of them in the bath along with a bath oil pearl and you’re all set for a relaxing, restorative soak.

Packaged in a cute mason jar, this gift looks like a jar of ocean treasures and adds a bit of charm to any tub it finds itself perched on.

How to make bath bombs

Mix the dry ingredients together very well, then add the coconut oil until the texture resembles wet sand.

Measure 1/2 cup of the mixture into a smaller bowl and add any essential oils or food dye along with the water into the dry mixture – add only small drops to avoid causing the mixture to fizz up.

Scoop the mixture into your bath bomb molds and press down.

Let the bath bombs dry 2-3 hours or overnight and then invert on a tray and pop out.

Repeat with the rest of the mixture 4 more times. (You can also mix things up and make another type of bath bomb while you’re making these.)

Once all of the bath bombs are done and dried, gently package in a mason jar with the bath oil pearls to act as “cushions.”

PS – If you want, right before you’re ready for your bath you can add a squirt of soap or shaving lotion into one of the seashells and stick a bath oil pearl in to form a “pearl in the oyster” bath bomb.
