In a galaxy far far away planets orbit and stars shine bright. Meanwhile, in your bathroom, you’re taking a nice relaxing bath with your galaxy bath bombs.
Watch the video tutorial here and follow along with the instructions (you can even watch it without sound if you want). Or go to the demo at the end to watch this bath bomb fizz!
Celebrate the new Star Wars movie in style. With these intergalactic bath bombs you can create your own starry sky at home. Keep it for yourself or give it as a Holiday Present to a fan (of bath bombs or sci fi movies a like). These are a guaranteed success!
How to Make Galaxy Bath Bombs:
(Scroll down to the bottom for the printable recipe)
The ingredients I use:
- 1/2 cup baking soda – Get it here
- 1/4 cup citric acid – Get it here
- 1/4 cup cornstarch – Get it here – I used arrowroot powder instead
- 1 tbsp. oil – I used almond oil – Get it here
- food or soap coloring
- some sprinkles (optional)
- A few drops of essential oil – I used grapefruit essential oil
1. Mix your dry ingredients
Put all of your dry ingredients together in a bowl, this is your baking soda, citric acid and cornstarch. Give it a good stir with a spoon.
2. Add your oil
Slowly add 1 tablespoon of oil while you keep stirring the mixture. I used a teaspoon (3 times in total) and added the oil drop by drop. This is your ‘wet’ phase and will make the mixture clump together. Some recipes use water or witch hazel, but when I do this, it starts to fizz right in the bowl. The oil also adds a nice moisturizing touch. Double win!
You can also add a few drops of essential oil at this point. I used grapefruit essential oil.
3. Coloring time!
Divide the mixture over several (smaller) bowls. Add a different color of food coloring to each bowl. Start by adding one drop, mix well and then add another. Because the food coloring is water based, again, you don’t want your bath bomb mixture to start fizzing! First the food coloring formed little specks in the mixture. But if you keep stirring it well it will color the whole batch.
I wanted to add sparkles or glitter, but I wasn’t sure what to use. Makeup glitter isn’t the best option to flush down the drain. That’s why I chose cake sprinkles. They are made of sugar and dissolve in warm water after a while. And I think they add a nice touch! I only added it to the yellow batch.
4. Create your epic bath bomb
You can use any type of mold you like, a star shape for example would work great as well. Since ’tis the season of Christmas, I found this amazing plastic ornament. It had some cheap Cristmas socks in it that I might use for a new DIY cup sleeve.
Fill up both sides of your mold with the mixture. Press it down tightly as you go. Fill up each half until it’s somewhat overflowing. Close up the ornament and twist both sides together. I wrapped a hair tie around it to make sure it stayed close.
I was probably more shocked than anyone that the galaxy bath bombs popped out looking like a perfect sphere. I pressed both halves together quite firmly after I closed the mold and I even put it in the fridge for a little while. But I’m not sure if that helped in any way. There’s one important rule though: when you open it, don’t twist! Just pull it apart slowly with your finger nails. Next time, I’m thinking about coating the mold very lightly with some oil.
When you’re ready to use it, drop one into your bath water. Watch it fizz away and let it reveal its colors, scents and sprinkles.
Now you can look deep into your very own galaxy!
Wrap it as a gift or keep it for yourself and start daydreaming about Galaxy Princesses and Jedi knights …
How to Make Galaxy Bath Bombs
- 1/2 cup baking soda
- 1/4 cup citric acid
- 1/4 cup cornstarch or arrowroot powder
- 1 tablespoon oil I like almond oil
- liquid food or soap coloring
- sprinkles optional
- few drops of essential oil
Combine baking soda, citric acid and cornstarch in a large mixing bowl. Stir well with a whisk or spoon.
Slowly add 1 tablespoon of carrier oil (like almond oil) while you keep stirring the mixture.
Add a few drops of essential oil (optional).
Divide the mixture over several bowls. Start by adding one drop of blue, red and yellow coloring to each bowl, mix well and then add another. Add a handful of sprinkles to the yellow batch (optional).
Take a handful of mixture in the palm of your hand and squeeze together. The mixture should stick together like damp sand.
Fill up both sides of your mold with the mixture. Layer the colors as you go. Press both sides together.
Let the bath bombs dry overnight before taking them out of their mold.
If you don't like to use sprinkles for your bath bomb, use jojoba beads, edible glitter dust or biodegradable glitter instead.
