Instructions
In a large mixing bowl, add the baking soda, citric acid, white kaolin clay and cornstarch. Whisk dry ingredients together.
Add the coconut oil. This binds all the ingredients together, so you bath bombs don’t crumble when you touch them!
Add the polysorbate 8This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub.
Add the scented oil
Mix all ingredients thoroughly. You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand. Divide the mixture evenly between the two smaller bowls.
Add 1-2 teaspoons of the blue glow in the dark powder to one bowl and the green glow in the dark powder to the other. Mix thoroughly.
Fill one side of the mold with the blue color and the other side of the mold with the green mixture and press molds together and grind to remove excess mixture. Gently tap each side of the mold to release the bombs. Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container until ready for use.
To get the bombs to glow, hold until a light for about 30 seconds and then take into a dark room. The bomb will glow brightly. If you want it to glow even brighter, hold under a black light after exposing to a regular light.
