1/2teaspoonMica powder(total! add less if batch is divided into different colours)
Instructions
Step 1: Make bath bomb mixture
Add dry ingredients to a mixing bowl and stir together until mixed.
Slowly pour in sweet almond oil.
Add in the drops of essential oil.
Stir this mixture together well, removing as many clumps as possible.
The mixture will appear dry, but should stick together if you pick it up and squeeze it together.
Step 2: Add Colour
If you want multiple colours of bath bombs, divide the mixture into several smaller bowls.Add mica powder colour of choice to the bowl and mix well until no white remains.
We divided the mixture into 4 colours and added only 1/8 teaspoon of mica powder to each colour. The more you add, the more vibrant the colour of the bath bomb.
Step 3: Form bath bombs
Spoon the mixture into one half of the mold. You can use one colour, or several. Use the back of a spoon or your fingers to press the mixture into the mold.
When the mold is full, press down on the mixture to pack it in tight.
Add another scoop on top of the packed mixture so that it's heaping out over the mold (don't pack it down).
Repeat with second half of mold.
Press the halves of the mold together carefully. Turn each half back and forth slightly while firmly pressing them together, allowing any extra mixture to fall out.
Carefully pull the molds apart. If the bath bomb isn't coming out easily, gently tap the outside of the mold with a spoon.
Unmold the second half of the bath bomb in the same way.
Let bath bomb dry on a baking tray (or other dry surface) overnight.
Your homemade bath bomb is complete!

Notes
TroubleshootingIf your bath bombs won't come out of the molds, they're too wet. You can try adding a little more cornstarch to your mixture. This recipe does NOT need any water.If they come out of the mold and crumble, the mixture is likely too dry or you didn't pack them into the mold tightly enough. First try firmly packing the mold again. Overflow the molds with even more of the mixture and really press the sides together tightly. If that doesn't work, try adding a few more drops of oil to your mixture.
