Stay on the Ground, While Reaching for the Stars: DIY 2020 Galaxy Bath Bomb



making of the diy galaxy bath bomb



We are going to talk about and share our 2020 version of a Galaxy Bath Bomb. Now when I think about the galaxy, I think about dark colors, with pops of bright colored stars, and other amazing unworldly elements.

So with this Galaxy bath bomb, we thought we would use both dark blues, but also make the bath bomb pop with super bright pinks, yellows and other eye catching colors, along with cosmetic grade glitters.

This bath bomb is all about letting yourself go, it doesn't have to be perfect, you can literally use the colors in any pattern you would like to an get a really cool affect. Each and every bath bomb you make with these colors will look slightly different, but that's the fun part about it.

2020 Galaxy Bath Bomb Recipe


Step 1:
Let's first start with making the large batch of the bath bombs ingredients and then we can equally distribute that mixture into 4 separate bowls for coloring.

After measuring out all your dry ingredients, pour them into one large bowl one at a time. This should include your baking soda, citric acid, SLSA, Epsom salt and kaolin clay. Make sure to get all the lumps out, which you may find with baking soda, just rub it between your hands until the mixture is fine. You can use a sifter as well.


Step 2:
Now take both your fragrance and carrier oil (grape-seed oil) and pour them into your ingredients. Mix well, making sure to get any clumps out.


Step 3:
Pour your mica colors into separate medicine cups. Add equal parts of your polysorbate 80 into the measuring cups. This will help to disperse/dissolve the mica and bring out there colors before adding to your separate mixtures.


Step 4:
Separate the mixture that's in your large bowl into 4 smaller bowls.


Recap: You should now have 4 bowls each with an equal amount of mixture in them, and then 4 medicine cups with the different colors.

Step 5:
Add each color, one at a time, to your mixtures. Mix each well. You may have to change gloves between them.


Step 6:
Add 2-3 spritz's of your water/alcohol mixture at a time to each of your colored mixtures. You are looking for a consistency like damp sand. You should be able to squeeze a handful of mix and it stays together. Once achieved you are ready to start molding.


Step 7:
I like to then take some cosmetic grade silver glitter and mix it with my dark blue color.


Step 8:
Start lining the two sides of your mold. Vary the colors as you build up each side of the mold. Alternate colors. Each side of the mold should be slightly overfilled, then press the two sides together.


Step 9:
Tap each side of the mold with a wooden spoon and take the top half off. Tip the bottom half over into your hand and let the bath bomb fall out.


Step 10:
Place your new galaxy bath bomb on a soft towel or egg carton foam and allow to dry for roughly 24 hours. Change up the way you alternate colors for the next mold. This is all about having fun, there is no science to how you pack the molds with the different colors.
