Easy Unicorn Bath Bombs DIY

Finally the unicorn craze has reached Tweak & Tinker HQ. Better late than never. And let me tell you it has hit hard. These days all I seem to be able to come up with are unicorn-y designs. These super adorable unicorn bath bombs are just the beginning (muhahaha).

This is a great project to make with your kids. It's easy enough (even my 2 year old had fun helping), but the fun part is when they take the bath bombs out of their molds and see how the design turned out.

Ready? Let's make some unicorn bath bombs!

What you'll need for 4 bath bombs:

Equipment:

• one medium and 2 small mixing bowls
• whisk
• measuring cup or scale
• very fine paint brush
• spray bottles for witch hazel
• round silicone muffin mold
• small treat bags for packaging (optional)

Ingredients:

• 1 cup (300 g)  baking soda
• ½ cup (150 g) citric acid
• ¼ cup (75 g) cornstarch
• 1 tablespoon grape seed oil (you can use coconut oil or canola oil instead)
• blue, red and yellow food coloring
• witch hazel
• 99% isopropyl alcohol (rubbing alcohol)
• 20 drops sweet orange essential oil
• sunset pink stardust mica powder
• pink watermelon stardust mica powder

Instructions:

1. Mix baking soda, citric acid and cornstarch together, work any clumps with your hands or a spatula and combine thoroughly
2. Add grape seed oil and combine (if you're using coconut oil, you have to melt it first)
3. Add essential oil and mix until well combined
4. Split you're mixture into 3 roughly equal parts
5. Add 8-10 drops of one color of food coloring to one part. Add one drop at a time while you whisk the mixture (this will prevent the fizzing to happen in your mixing bowl). Repeat with the other colors until you have one bowl with pink, one with blue and one with yellow.
6. With your hands (you can use gloves for this) work out the clumps and make sure the food coloring is evenly combined - for this it's best to take the mixture in between the palms of your hands and gently rub them together.
7. Spritz the mixture with witch hazel until the mixture holds it's shape after being squeezed together in your fist (if you want to know what that looks like check out the video in this post).
8. Start filling the molds with the pink mixture. Press the mixture to one side of the mold and make sure the rest of the mold is clear so that you get fairly distinct layers of color
9. Proceed with the yellow color, placing it right next to the pink. Keep the rest of the mold clear.
10. Fill the remainder with the blue color
11. When your molds are filled up all the way firmly press the mixture down
12. Let the bath bombs sit and harden in the mold overnight or for at least 10 hours
13. Unmold by gently pulling on the sides of the mold. Making sure that each one is completely detached from the side before gently pushing them out by pressing on the bottom of the mold
14. Mix ⅛ teaspoon of isopropyl alcohol with ⅛ teaspoon of sunset pink mica
15. Use mica "paint" to draw the unicorn eyes and nostrils, make sure you wipe any excess color of the paint brush before drawing
16. Mix ⅛ teaspoon of isopropyl alcohol with ⅛ teaspoon of pink watermelon mica and draw the cheeks
17. Let mica dry for 30 minutes
18. Package treat bags with a cute ribbon or store in an airtight container

Until next time. Happy Tinkering!
