Northern Lights Bath Bomb Recipe that glow in the dark and captures the beauty of the dancing lights of the Aurora Borealis.
In a large mixing bowl, add the baking soda, citric acid, cream of tartar and Epsom salts. Mix.
In a second bowl, add the coconut oil and melt it briefly in the microwave until it just liquefies.
Add polysorbate 80 and essential oil. Mix.
If you want to use the glitter, mix it into the liquid now.
Next pour the liquid mix into the dry mix bowl and start working it all together with your hands until it feels like wet sand.
Separate mixture into 6 small bowls.
Add 1 tablespoon of each mica powder into each small bowl. Mix in thoroughly. If you want a darker color, add in an additional bit of color (maybe a teaspoon, don't go crazy!)
Put on gloves if you wish now. Then use your hands to work the mica powder into each bowl until the colour is evenly distributed.
Fill both sides of the mold with the mixture. You can either create neat layers or splatter it into the mold in a more chaotic pattern. It's totally up to you! Fill each half until loosely heaped.
Press molds together and grind to remove excess mixture.
Gently tap each side of the mold to release the bombs.
Set the bath bombs in the mini muffin tray and set somewhere warm and dry to set for 24 to 48 hours.
Store in an airtight container until ready to use.
