One thing is for sure – Lily is showing no signs of NOT being obsessed with unicorns and rainbows ANY time soon. I’m not complaining either – LOL – she is one of the easiest kids to shop for!  I am always on the lookout for fun craft and decor ideas that I know she will love. Rainbows are ALWAYS a hit!

This DIY is a really fun one.  It would be a great activity to make with friends OR would be perfect to gift. The bath bomb recipe below contains essential oils.  You can customize the oils based on the scents you want your bath bombs to have.

How to Make DIY Rainbow Unicorn Bath Bombs

1. In a large mixing bowl, add the following: baking soda, bentonite clay, citric acid, Milk and Honey Epsom salts and cornstarch.

2. Whisk these dry ingredients together until combined.

3. Add the coconut oil which will bind the ingredients together.

4. Next, add the cocoa butter.  (I love using this ingredient because it not only helps the ingredients stick better, but it’s also a great moisturizer for your skin.)

5.  Add the polysorbate 80. This ingredient helps the coconut oil disperse more evenly in your bath water and makes the bath bombs bubbly and prevents the mica from sticking to the side of the tub.

6. Add the essential oils and glitter.  Mix these together well.  You can use your hands to break down the lumps.  Make sure these ingredients are very well mixed together.  Your mixture is the correct consistency when you press it into your hands and it feels like wet sand.

7. Separate the mixture into 5 smaller bowls. Mix 1 TBSP of colored mica into each bowl: purple, blue, yellow, pink, green.

8. Layer the mixture into each side of your bath bomb mold (use any color order you’d like). Fill the molds until the mixture is just slightly overflowing.

9. Press the mold halves together and grind them gently to remove excess mixture.

10. Tap each side of the mold gently to release the bath bomb.

11. Allow to dry a minimum of 24 hours before using in a bath. I like to place fresh bath bombs in a metal muffin tin for drying.
