Chemistry in the bath tub with fizzing eyeball Halloween bath bombs you can make easily with the kids. Explore a cool chemical reaction between an acid and base while you get clean! We love simple Halloween activities for kids!
How To Make Bath Bombs
Supplies:
- 1 cup baking soda
- ½ cup citric acid
- ½ cup epsom salts
- ½ cup cornstarch
- 2 tsp. coconut oil
- Light green mica powder
- Googly eyes
- Bath bomb mold
Spray bottle with water
- Optional – Essential oil
Bath Bomb Size Breakdown:
- Small molds (about 1.5 inches in diameter): This recipe will make around 6 bath bombs.
- Medium molds (about 2 inches in diameter): This recipe will make around 4 bath bombs.
💡Make homemade Halloween soap too!
Instructions:
STEP 1. Combine all of the dry ingredients, including mica powder until your desired color is reached. You only need a bit as the color is very vibrant.
STEP 2. Next, add your choice of essential oil to the scent strength you like, start with 12 drops. Lavender is a great choice for a relaxing bedtime soak. For a little one with the sniffles you might add eucalyptus, need to wake them up in the morning any citrus essential oil will do just that!
STEP 3. Slowly wet your mixture and mix with your hands, just a spritz of water at a time just until you are able to squeeze it and it maintains its shape, any wetter and the fizzing reaction will go off too soon!
STEP 4. Place a google eye in the bottom of one half of the mold, add mixture and pack tightly, keep adding eyes and packing until each half is overfilled, press them together firmly.
Let your bath bombs dry for several hours until completely hardened. I usually let them sit overnight.

Why Do Bath Bombs Fizz?
Kids will love these spooky googly-eyed bath bombs! They’re fun to make and even more fun to use in the bath.
This homemade recipe is kid-friendly and avoids artificial ingredients found in store-bought versions. Skip the fake fragrances, artificial dyes, and glitter!
The best part? The fizzy action is a cool chemistry experiment! Bath bombs fizz when water triggers a reaction between citric acid (the acid) and baking soda (the base), producing carbon dioxide gas—just like a mini volcano!
💡 Also, try this bubbling brew for Halloween to further explore baking soda and vinegar.
Fun fact: cornstarch helps slow down chemical reactions!
This reaction also helps break apart the bath bomb to release any hidden treasures and fragrances you have added!
